Preventing obesity. Childhood Obesity: Global Trends, Causes, and Prevention Strategies
How has childhood obesity rates changed globally over the past few decades. What are the main factors contributing to the rise in childhood obesity worldwide. Which regions are most affected by childhood obesity and why. What are the health consequences of childhood obesity. How can parents, schools, and communities help prevent childhood obesity.
The Global Epidemic of Childhood Obesity
Childhood obesity has emerged as one of the most pressing public health challenges of the 21st century. Over the past few decades, rates of overweight and obesity in children have risen dramatically around the world, with serious implications for children’s health and wellbeing.
In 2010, an estimated 43 million preschool children under the age of 5 were overweight or obese globally – a 60% increase since 1990. If current trends continue unabated, projections suggest that by 2020, 9% of all preschoolers worldwide – nearly 60 million children – will be overweight or obese.
While obesity rates tend to be higher in adults, many countries have seen the problem escalate more rapidly in children compared to adults in recent years. This global epidemic affects both developed and developing nations, though the greatest burden in terms of sheer numbers falls on poorer countries where 35 million of the world’s 43 million overweight preschoolers reside.
Regional Trends in Childhood Obesity
North America
The United States has seen childhood obesity rates triple over the past three decades. Today, one in six U.S. children is obese, while one in three is overweight or obese. Some key trends in the U.S. include:
- Obesity is more prevalent among boys (19%) than girls (15%)
- Hispanic (21%) and non-Hispanic Black (24%) youth have higher obesity rates than non-Hispanic white youth (14%)
- Nearly 10% of U.S. infants have a high weight-for-length ratio
Canada has also experienced rising childhood obesity rates, though they remain lower than in the U.S. In 2007-2008, about 9% of Canadian youth ages 6-17 were obese. Obesity rates are particularly high among Canada’s Aboriginal populations.
Latin America and the Caribbean
While comprehensive data is lacking for Latin America and the Caribbean, childhood overweight and obesity have clearly become significant issues in the region. More children are overweight than underweight in many countries. Mexico faces a particularly severe epidemic, with childhood obesity rates among the highest in the world.
Causes of the Global Rise in Childhood Obesity
The global increase in childhood obesity can be attributed to several interconnected factors:
- Dietary changes: Shift towards energy-dense, nutrient-poor foods high in fat and sugars
- Decreased physical activity: More sedentary lifestyles, increased screen time
- Environmental factors: Greater availability of unhealthy foods, limited access to healthy options
- Socioeconomic factors: Links between poverty and obesity in many countries
- Cultural influences: Changes in traditional eating patterns, adoption of Western diets
The nutrition transition accompanying economic development in many low- and middle-income countries has led to rapid changes in diet and lifestyle, contributing to rising obesity rates.
Health Consequences of Childhood Obesity
Childhood obesity can harm nearly every system in a child’s body, leading to serious short- and long-term health consequences:
- Cardiovascular problems: High blood pressure, high cholesterol
- Endocrine issues: Type 2 diabetes, early puberty
- Gastrointestinal disorders: Fatty liver disease, gallstones
- Pulmonary complications: Asthma, sleep apnea
- Musculoskeletal problems: Joint pain, increased fracture risk
- Psychological effects: Depression, low self-esteem, social isolation
Additionally, obese children are substantially more likely to become obese adults, increasing their risk of various chronic diseases later in life.
Prevention Strategies for Childhood Obesity
Addressing the global childhood obesity epidemic requires a multi-faceted approach involving families, schools, communities, and policymakers. Some key prevention strategies include:
Family-Based Interventions
How can families promote healthy habits at home? Parents can play a crucial role by:
- Providing nutritious meals and snacks
- Limiting sugary drinks and high-calorie foods
- Encouraging regular physical activity
- Modeling healthy behaviors
- Limiting screen time
School-Based Programs
Schools can create environments that support healthy eating and physical activity through:
- Offering nutritious school meals
- Removing unhealthy foods from vending machines
- Providing quality physical education
- Implementing classroom nutrition education
- Creating safe routes for walking/biking to school
Community Initiatives
Communities can support childhood obesity prevention by:
- Improving access to healthy foods in underserved areas
- Creating safe spaces for physical activity (parks, playgrounds)
- Implementing farm-to-school programs
- Organizing community health events and education programs
Policy Measures
Government policies can help create environments that promote healthy lifestyles:
- Regulating food marketing to children
- Implementing taxes on sugary beverages
- Mandating clear food labeling
- Subsidizing healthy foods
- Investing in public health campaigns
Challenges in Tracking Global Childhood Obesity
Monitoring childhood obesity trends on a global scale presents several challenges:
- Lack of nationally representative surveys in many countries
- Inconsistent measurements over time
- Varying definitions of childhood obesity (CDC, WHO, IOTF)
- Difficulty comparing data between regions
These factors make it challenging to obtain a comprehensive picture of childhood obesity trends worldwide and to make accurate comparisons between countries and regions.
The Dual Burden of Malnutrition
While childhood obesity rates are rising globally, many regions still struggle with child hunger and undernutrition. This creates a dual burden, particularly in low- and middle-income countries:
- Infectious diseases associated with malnutrition
- Chronic diseases linked to obesity and Western lifestyles
This paradoxical situation presents unique challenges for public health systems in developing countries, requiring strategies that address both undernutrition and overnutrition simultaneously.
The Role of Globalization in Childhood Obesity
How has globalization contributed to the rise in childhood obesity? Globalization has played a significant role in the worldwide increase of childhood obesity through several mechanisms:
- Economic growth: As countries become wealthier, obesity rates tend to rise
- Urbanization: Urban environments often promote sedentary lifestyles and unhealthy food choices
- Food systems: Global food supply chains have increased availability of processed, high-calorie foods
- Cultural influences: Adoption of Western dietary patterns and food preferences
- Technology: Increased screen time and reduced physical activity
The nutrition transition that accompanies economic development has led many low- and middle-income countries to rapidly shift from traditional diets to more Western-style eating patterns, contributing to rising obesity rates.
Case Study: Mexico’s Childhood Obesity Epidemic
Mexico provides a stark example of how globalization and economic development can impact childhood obesity rates. The country has seen a dramatic rise in childhood obesity over the past few decades, with rates now among the highest in the world. Factors contributing to this trend include:
- Increased consumption of sugar-sweetened beverages
- Greater availability of processed, energy-dense foods
- Decline in traditional dietary patterns
- Reduced physical activity due to urbanization and technology
- Marketing of unhealthy foods to children
Mexico’s experience highlights the need for comprehensive policies and interventions to address childhood obesity in the context of rapid economic and social changes.
Innovative Approaches to Childhood Obesity Prevention
As the global childhood obesity epidemic continues to evolve, researchers and policymakers are exploring innovative approaches to prevention and intervention. Some promising strategies include:
Technology-Based Interventions
How can technology be leveraged to promote healthy behaviors in children? Some innovative approaches include:
- Mobile apps for tracking diet and physical activity
- Gamification of health education and behavior change
- Wearable devices to encourage movement
- Virtual reality experiences promoting healthy lifestyles
- Social media campaigns targeting youth
Environmental Design
Creating built environments that promote physical activity and healthy eating:
- Active design in schools and public spaces
- Urban planning that prioritizes walkability and green spaces
- Redesigning supermarkets to encourage healthier choices
- Implementing “healthy food zones” around schools
Behavioral Economics
Applying insights from behavioral economics to nudge children towards healthier choices:
- Changing default options in school cafeterias
- Using attractive packaging for healthy foods
- Implementing choice architecture in food environments
- Providing immediate rewards for healthy behaviors
Community Engagement
Empowering communities to take an active role in childhood obesity prevention:
- Youth-led health initiatives
- Peer education programs
- Community gardens and cooking classes
- Partnerships between schools, families, and local organizations
The Economic Impact of Childhood Obesity
Beyond its health consequences, childhood obesity also has significant economic implications. What are the economic costs associated with the global rise in childhood obesity?
- Increased healthcare expenditures for obesity-related conditions
- Lost productivity due to obesity-related illnesses and disabilities
- Higher rates of absenteeism in schools
- Potential reduction in human capital and economic growth
A study by the World Obesity Federation estimated that the global economic impact of obesity could reach $1.2 trillion annually by 2025 if current trends continue. This underscores the urgency of addressing childhood obesity not only as a health issue but also as an economic imperative.
Cost-Effectiveness of Prevention
Investing in childhood obesity prevention can yield significant economic benefits:
- Reduced healthcare costs in the long term
- Improved academic performance and future earnings potential
- Increased productivity and economic output
- Reduced burden on public health systems
Studies have shown that many obesity prevention interventions are cost-effective or cost-saving when considering long-term health and economic outcomes.
The Role of the Food Industry in Childhood Obesity
The food industry plays a significant role in shaping children’s food environments and eating habits. How can the food industry contribute to childhood obesity prevention?
Potential Actions by the Food Industry
- Reformulating products to reduce sugar, salt, and unhealthy fats
- Implementing responsible marketing practices, especially for children
- Providing clear and accurate nutritional information
- Developing and promoting healthier food options
- Supporting community health initiatives
Regulatory Approaches
Governments around the world are implementing various regulatory measures to address the role of the food industry in childhood obesity:
- Restrictions on food marketing to children
- Mandatory front-of-pack nutrition labeling
- Taxes on sugar-sweetened beverages and unhealthy foods
- Limits on portion sizes in restaurants
- Bans on trans fats and other harmful ingredients
These regulatory approaches aim to create food environments that make it easier for children and families to make healthier choices.
The Future of Childhood Obesity: Trends and Projections
What does the future hold for global childhood obesity rates? While the outlook remains concerning, there are some signs of progress:
- Some high-income countries have seen childhood obesity rates stabilize in recent years
- Increased awareness and policy action on childhood obesity globally
- Promising results from comprehensive prevention programs in some communities
However, significant challenges remain:
- Continued rise in obesity rates in many low- and middle-income countries
- Persistent disparities in obesity rates among different socioeconomic and ethnic groups
- Ongoing changes in food systems and environments that promote unhealthy behaviors
Projections suggest that without significant intervention, global childhood obesity rates will continue to rise, particularly in developing countries. However, the implementation of evidence-based prevention strategies and policies could help reverse this trend and improve the health prospects for future generations.
Emerging Research Directions
Ongoing research in childhood obesity is exploring several promising areas:
- The role of the gut microbiome in obesity development
- Epigenetic factors influencing obesity risk
- Personalized nutrition approaches based on genetic profiles
- Early life interventions to prevent obesity in infancy and early childhood
- Novel pharmacological treatments for severe obesity in adolescents
These areas of research may lead to new strategies for preventing and treating childhood obesity in the coming years.
Child Obesity | Obesity Prevention Source
Too Many Kids Are Too Heavy, Too Young
Childhood obesity has been called “one of the most serious public health challenges of the 21st century,” and with good reason. (1)
Obesity can harm nearly every system in a child’s body-heart and lungs, muscles and bones, kidneys and digestive tract, as well as the hormones that control blood sugar and puberty-and can also take a heavy social and emotional toll. (2) What’s worse, youth who are overweight or obese have substantially higher odds of remaining overweight or obese into adulthood, (3) increasing their risk of disease and disability later in life.
Globally, an estimated 43 million preschool children (under age 5) were overweight or obese in 2010, a 60 percent increase since 1990. (4) The problem affects countries rich and poor, and by sheer numbers, places the greatest burden on the poorest: Of the world’s 43 million overweight and obese preschoolers, 35 million live in developing countries. By 2020, if the current epidemic continues unabated, 9 percent of all preschoolers will be overweight or obese-nearly 60 million children. (4)
Obesity rates are higher in adults than in children. But in relative terms, the U.S., Brazil, China, and other countries have seen the problem escalate more rapidly in children than in adults. (5)
Of course, some regions still struggle mightily with child hunger, such as Southeastern Asia and sub-Saharan Africa. (6) But globalization has made the world wealthier, and wealth and weight are linked.
As poor countries move up the income scale and switch from traditional diets to Western food ways, obesity rates rise. (7) One result of this so-called “nutrition transition” is that low- and middle-income countries often face a dual burden: the infectious diseases that accompany malnutrition, especially in childhood, and, increasingly, the debilitating chronic diseases linked to obesity and Western lifestyles.
It’s surprisingly challenging to track childhood obesity rates across the globe. Many countries do not field nationally representative surveys that measure heights and weights of school-aged children, or don’t have repeated consistent measurements over time. Dueling definitions of childhood obesity-from the U.S. Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO), and the International Obesity Task Force (IOTF)-further complicate matters, making it hard to compare data between regions.
This article gives a brief overview of global obesity trends in children. A related article covers obesity trends in adults.
North America
Over the past three decades, childhood obesity rates have tripled in the U.S., and today, the country has some of the highest obesity rates in the world: one out of six children is obese, and one out of three children is overweight or obese. (8) Though the overall U.S. child obesity rate has held steady since 2008, some groups have continued to see increases, and some groups have higher rates of obesity than others:
- In the 1970s, 5 percent of U.
S. children ages 2 to 19 were obese, according to the CDC’s current definition; by 2008, nearly 17 percent of children were obese, a percentage that held steady through 2010. (8,9)
- Obesity is more common in boys than girls (19 percent versus 15 percent). (8)
- Obesity rates in boys increased significantly between 1999 and 2010, especially among non-Hispanic black boys; but obesity rates in girls of all ages and ethnic groups have stayed largely the same. (8)
- Hispanic (21 percent) and non-Hispanic black (24 percent) youth have higher rates of obesity than non-Hispanic white youth (14 percent), a continuing trend. (8)
- Nearly 10 percent of U.S. infants had a high “weight for recumbent length”-a measure that’s similar to the body mass index but used in children from birth to age 2. (8)
- From 1999 to 2010, Mexican American infants were 67 percent more likely to have a high weight for recumbent length than non-Hispanic white infants. (8)
Canada has also seen a rise in childhood obesity since the late 1970s-overall, obesity rates have more than doubled, and in some age groups, tripled. (10) But childhood obesity rates are still a good bit lower there than they are in the U.S. In 2007-2008, nearly 9 percent of Canadian youth ages 6 to 17 were obese, based on the IOTF age-specific cutoffs. (10) Child obesity is a bigger problem among Canada’s Aboriginal groups: A survey of Aboriginal groups who live outside of reservations found that in 2006, nearly 33 percent of children ages 6 to 8 were obese, as were 13 percent of children ages 9 to 14. (10)
Latin America and the Caribbean
Though data are scarce from Latin America and the Caribbean, it’s clear that childhood overweight and obesity have become sizable problems-and that overall, more children in the region are overweight than underweight.
Preschoolers
Roughly 7 percent of children under the age of 5 in Latin America and the Caribbean were estimated to be overweight or obese in 2010, according to the WHO growth standards. (4) While under-nutrition remains a concern in this age group, the region has seen substantial reductions in child underweight over the past two decades, from 7 percent in 1990 to 3 percent in 2010. (6)
School-Age Children and Adolescents
Nationally representative data are limited in these age groups, but again, the best available data suggest that obesity has become a serious problem. In Mexico, for example, a 2006 government health survey measured heights and weights of children across the country. It found that nearly 10 percent of 15-year-olds were obese and 33 percent were overweight or obese, using the adult cut points for overweight (BMI of 25 or higher) and obese (BMI of 30 or higher), cut points that likely underestimate the true rates of overweight and obesity in adolescents. (11) In Argentina, meanwhile, investigators measured heights and weights from a representative sample of 1,688 children ages 10 to 11 in Buenos Aires’ public schools. They found that 35 percent of the children were overweight or obese, using the CDC’s definition, and about 4 percent were underweight. (12) Of note, stunting and overweight coexist in many developing countries, and stunting my increase the risk of obesity later on in life.
Europe
Surprisingly, Europe has less-than-complete data on childhood obesity trends, especially from eastern countries. And until recently, data were not gathered in a consistent way across the continent, making it very hard to compare numbers from country to country. But the best available estimates find that over the past few decades, obesity rates have been rising among children in many countries. (13,14) More recently, rates seem to have hit a plateau in a few countries, among some age groups:
Preschoolers
Overweight and obesity rates at 4 years of age vary quite a bit from country to country, according to a recent systematic review of studies from the 27 countries in the European Union (EU). Spain had the highest rate-just over 32 percent-and Romania had the lowest rate, about 12 percent. (14) Keep in mind, though, that only 18 of 27 countries had data available, and often, the sample sizes were small or the data had other limitations. Five countries had repeated surveys of children ages 2 to 5, offering a glimpse of trends over the past few decades-the Czech Republic, England, France, the Netherlands, and Romania. Of those, only England showed a rise in obesity rates, from about 18 percent in 1995 to 23 percent in 2002.
School-Age Children
The World Health Organization European Childhood Obesity Surveillance Initiative recently began tracking child obesity rates across 15 countries, using the WHO child growth standards. The first analysis, based on 2007-2008 data from 13 countries (Belgium, Bulgaria, Cyprus, Czech Republic, Ireland, Italy, Latvia, Lithuania, Malta, Norway, Portugal, Slovenia, Sweden), finds that 24 percent of European children ages 6 to 9 are overweight. (15) A second wave of data collection, in 2010, has yet to be reported. Over time, this survey should offer more insights into European trends within and across countries.
Adolescents
Cyprus, Greece, Spain, and England have some of the highest obesity rates among youth ages 10 to 18, according to a recent systematic review of studies from 30 countries (the 27 EU members plus Iceland, Norway, and Switzerland). (13) But again, the data are limited and of varying quality; only 18 of 30 countries had nationally representative data from measured heights and weights. Fourteen countries had trend data available, though some were based on self-reported measures with small samples. (13) Most of these countries showed increases in obesity rates over the past few decades. France, however, showed no changes in obesity rates from 1998 to 2007 in children ages 3 to 14, a finding echoed by subsequent reports. (16–18) Sweden saw no change from 2001 to 2007 among 16-year-old youth, and a more recent review finds obesity rates have held steady in other age groups as well.(18)
Africa
Hunger, underweight, and stunting have long been the more pressing child nutrition concerns across Africa, and even today, 20 to 25 percent of preschoolers in sub-Saharan Africa are underweight. (6) Yet here, too, child obesity rates are on the rise: The percentage of preschoolers in Africa who are overweight or obese more than doubled over the past two decades, from 4 percent in 1990 to 8. 5 percent in 2010. (4) A closer look at the numbers, though, shows much higher rates in Northern Africa than the rest of the continent:
Preschoolers
In Northern Africa, an estimated one in six preschool-aged children is overweight or obese-the highest rate in the world, and triple that in 1990. (4) There’s quite a bit of variability from country to country, however: About 20 percent of Egypt’s preschoolers were overweight or obese in 2008, compared with 5 percent in Sudan. (4)
In sub-Saharan Africa, meanwhile, overweight and obesity rates among preschoolers are still in the single digits-roughly 9 percent in Middle Africa, 6 percent in Western Africa, 7 percent in Eastern Africa, and 8 percent in Southern Africa. (4) But for most of the region, these rates are double or triple what they were two decades ago; only Southern Africa has seen the rate drop slightly since 1990.
Children and Adolescents
There are scant few nationally representative surveys available from older youth in the region, but available data suggest obesity is increasing in this age group, as well. In South Africa, for example, only about 1 percent of youth ages 8 to 11 were overweight or obese in 1994, based on the IOTF cut points. (19) By 2006, about 17 percent of South African girls and 11 percent of boys ages 6 to 13 were overweight or obese. (20)
Asia
There’s quite a bit of diversity from region to region, however. While South Asian countries like Bangladesh, India, and Pakistan have low obesity rates, their large populations add up to large numbers of children who are overweight or obese.Even though child hunger remains the most pressing nutritional concern for much of Asia-n South Asia, for example, one in three preschool children is underweight-the region has also seen dramatic increases in child obesity. Overall in Asia (excluding Japan), nearly 5 percent of preschoolers were estimated to be overweight or obese in 2010, a 53 percent increase in prevalence since 1990. (4) That translates into 17.7 million Asian preschoolers being overweight or obese.
It’s important to note that in Asian adults, the health complications associated with overweight and obesity start at a lower BMI than seen in the U. S. and Europe. So many of these estimates of child obesity prevalence in Asia likely underestimate the true public health burden of obesity in Asia.
Preschoolers
In 2010, preschooler obesity rates were far higher in Western Asia (which includes the Middle East) than in Eastern, Southeastern, or South Central Asia (roughly 15, 5, 5, and 4 percent, respectively). (4) But South Central Asia had the largest number of overweight preschoolers of any region on the world-an estimated 6.6 million children. (4)
School-Age Children and Adolescents
Nationally representative data are scarce for older children in Asia, but taken together, paint a worrisome picture of obesity trends. In China, over the past 20 years, nationally representative studies of youth ages 8 to 18 have shown a dramatic rise in obesity: In 1985, only 2 percent of boys and 1 percent of girls were overweight or obese, based on Chinese-specific cut points (at age 18, a BMI of 24 for overweight and 28 for obesity). By 2005, roughly 14 percent of boys and 9 percent of girls were overweight or obese-a total of 21 million children. (21) In India, meanwhile, the largest study to date covered five urban areas and included nearly 40,000 children ages 8 to 18. It found that 14 percent were overweight or obese-a number that, if extrapolated to urban youth across India, amounts to an estimated 15 million children. (20) In Western Asia, the Arabian Gulf States have especially high rates of overweight and obesity among schoolchildren. A nationally representative Kuwaiti survey in 2006 found that about 44 percent of boys and 46 percent of girls ages 10 to 14 were overweight or obese, according to the CDC’s pre-2000 definition. (22)
Oceania
The major developed countries in Oceania-Australia and New Zealand-have childhood obesity rates in the double digits, but there’s some evidence that rates have hit a plateau over the past decade. (18,23)
In Australia, a systematic review of 41 studies from 1985 through 2008 found that obesity rates in children ages 2 to 18 rose through the mid-1990s, but have held relatively stable since then. (23) In 2008, 21 to 25 percent of Australian boys and girls were overweight or obese, and 5 to 6 percent were obese.
In New Zealand, nationally representative data show that about 28 percent of children ages 5 to 14 were overweight or obese in 2006-2007, a rate that was unchanged from 2002. (18) Overweight and obesity rates are much higher in some of New Zealand’s ethnic groups (Maori, 37 percent, and Pacific Islanders, 57 percent), but are also largely unchanged since 2002.
The Bottom Line: It’s Never Too Early to Start Preventing Obesity
Even among the youngest of children, it’s clear that obesity rates are rising across the globe. Equally clear is that it’s very, very hard for anyone who becomes overweight to lose weight, at any age. Preventing obesity in a child’s earliest years (and even before birth, by healthy habits during pregnancy) confers a lifetime of health benefits. And it’s the most promising path for turning around the global epidemic. (24)

Obesity Prevention Source
Many factors influence body weight-genes, though the effect is small, and heredity is not destiny; prenatal and early life influences; poor diets; too much television watching; too little physical activity and sleep; and our food and physical activity environment.
What Tips the Scales Toward Excess Weight?
The causes of obesity are as varied as the people it affects.
At its most basic, of course, obesity results when someone regularly takes in more calories than needed. The body stores these excess calories as body fat, and over time the extra pounds add up. Eat fewer calories than the body burns, weight goes down. This equation can be deceptively simple, though, because it doesn’t account for the multitude of factors that affect what we eat, how much we exercise, and how our bodies process all this energy. A complex web surrounds a basic problem.
What are some of the factors that increase the risk of obesity?
Genes Are Not Destiny
Heredity plays a role in obesity but generally to a much lesser degree than many people might believe. Rather than being obesity’s sole cause, genes seem to increase the risk of weight gain and interact with other risk factors in the environment, such as unhealthy diets and inactive lifestyles. And healthy lifestyles can counteract these genetic effects.
Prenatal and Postnatal Influences
Early life is important, too. Pregnant mothers who smoke or who are overweight may have children who are more likely to grow up to be obese adults. Excessive weight gain during infancy also raises the risk of adult obesity, while being breastfed may lower the risk.
Unhealthy Diets
What’s become the typical Western diet-frequent, large meals high in refined grains, red meat, unhealthy fats, and sugary drinks-plays one of the largest roles in obesity. Foods that are lacking in the Western diet-whole grains, vegetables, fruits, and nuts-seem to help with weight control, and also help prevent chronic disease.
Too Much Television, Too Little Activity, and Too Little Sleep
Television watching is a strong obesity risk factor, in part because exposure to food and beverage advertising can influence what people eat. Physical activity can protect against weight gain, but globally, people just aren’t doing enough of it. Lack of sleep-another hallmark of the Western lifestyle-is also emerging as a risk factor for obesity.
Toxic Environment-Food and Physical Activity
As key as individual choices are when it comes to health, no one person behaves in a vacuum. The physical and social environment in which people live plays a huge role in the food and activity choices they make. And, unfortunately, in the U.S. and increasingly around the globe, this environment has become toxic to healthy living: The incessant and unavoidable marketing of unhealthy foods and sugary drinks. The lack of safe areas for exercising. The junk food sold at school, at work, and at the corner store. Add it up, and it’s tough for individuals to make the healthy choices that are so important to a good quality of life and a healthy weight.
Obesity and its causes have, in many ways, become woven into the fabric of our society. To successfully disentangle them will take a multifaceted approach that not only gives individuals the skills to make healthier choices but also sets in place policy and infrastructure that support those choices.

Prevention of obesity – Gryazinskaya CRH
Obesity is a disease that can be cured simply by adjusting the lifestyle. All you need is your desire and many of the problems that excess weight entails will bypass you.
Preventive measures.
Nutrition: The basis of the diet for obesity is a “healthy” diet, its principle is the dosed intake of a variety of foods. There are general recommendations for a diet for obesity:
Eat plenty of fiber-rich foods every day. These are fruits, vegetables, legumes, cereals. All these products are low-calorie, rich in vitamins and minerals.
Sweets, muffins, fried foods, canned food, store-bought juices, lemonades, fast food – it is better to exclude from the menu.
Dishes of fast carbohydrates and proteins, it is better to combine with slow carbohydrates. For example, meat food with side dishes of vegetables and cereals.
Fast carbohydrate dishes are best taken at the beginning of the day (in the morning), when the metabolism is more intense.
Eliminate animal fats. Replace them with healthy vegetable oils (olive, sesame).
Be careful with spicy, spicy and sour foods – do not abuse them, because they tend to stimulate the appetite.
Do not forget that food should be varied. Then it will satisfy the body’s need for vitamins and trace elements.
Limit alcohol, as alcoholic drinks will add extra calories, no nutrients, and whet your appetite.
Drink plenty of water to quench your thirst. Pure water contains 0 calories, and if you drink a glass of water 30 minutes before a meal, then the feeling of satiety will come earlier. The last meal should be 2.5-3 hours before bedtime.
Physical activity: It is possible to increase the consumption of kilocalories entering the body only through physical activity. An untrained person should not immediately start intensive training. For the prevention of obesity, cyclic types of physical education are best suited: skiing, swimming, running. The easiest is to walk at a brisk pace for 40 minutes 3-4 times a week or take at least 10,000 steps a day every day. A prerequisite is control over your condition.
Psychological problems: Not all causes of obesity are due to human physiology. His psyche plays an important role in the appearance of excess weight. Sleep disturbance, negative emotions, frequent stress can increase appetite and encourage increased food intake, which in turn leads to weight gain. Having solved at least partially the problem associated with the psychological aspect of obesity, it is possible to prevent weight gain.
Remember: By losing weight, you reduce the risk of a large number of diseases such as diabetes, atherosclerosis, arterial hypertension, stroke, myocardial infarction and improve your quality of life!
