The Growing 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 skyrocketed around the world, with serious implications for children’s health and well-being. Let’s examine the scope of this global epidemic and its impacts.

Alarming Statistics on Childhood Obesity

The numbers paint a concerning picture of how widespread childhood obesity has become:

• In 2010, an estimated 43 million preschool children under age 5 were overweight or obese globally – a 60% increase from 1990.
• If current trends continue, 9% of all preschoolers worldwide (nearly 60 million children) are projected to be overweight or obese by 2020.
• In the United States, one out of six children is obese, and one out of three is overweight or obese.
• Obesity rates in U.S. children have tripled over the past three decades.

Why has childhood obesity increased so dramatically in recent years? Several factors have contributed to this trend, including shifts toward more sedentary lifestyles, increased consumption of processed and high-calorie foods, and socioeconomic changes that have altered eating patterns.

Health Consequences of Childhood Obesity

Excess weight in childhood can negatively impact almost every system in a child’s body, with both immediate and long-term health ramifications.

Physical Health Impacts

Obesity in children can affect:

• Heart and lung function
• Muscular and skeletal development
• Kidney function
• The digestive system
• Hormones controlling blood sugar and puberty

Mental and Emotional Health

Beyond the physical effects, childhood obesity often takes a significant toll on mental and emotional well-being. Overweight and obese children may face:

• Social stigma and bullying
• Low self-esteem
• Depression and anxiety
• Body image issues

How does childhood obesity affect long-term health outcomes? Children who are overweight or obese are substantially more likely to remain so into adulthood, increasing their risk of various chronic diseases and health complications later in life.

Global Trends in Childhood Obesity

While childhood obesity is a global issue, its prevalence and trends vary significantly across different regions and countries.

North America

The United States has some of the highest childhood obesity rates in the world:

• 17% of children ages 2-19 were obese in 2010, up from just 5% in the 1970s.
• Obesity is more common in boys (19%) than girls (15%).
• Hispanic (21%) and non-Hispanic black (24%) youth have higher obesity rates than non-Hispanic white youth (14%).

Canada has also seen 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.

Latin America and the Caribbean

While comprehensive data is limited, childhood overweight and obesity have become significant issues in this region. More children are overweight than underweight in many Latin American and Caribbean countries, reflecting a global nutrition transition.

Europe

Childhood obesity rates vary widely across European countries:

• Southern European countries like Greece, Italy, and Spain tend to have higher rates.
• Northern European countries generally have lower rates.
• Eastern European countries have seen rapid increases in childhood obesity since the fall of the Soviet Union.

Asia

Childhood obesity is a growing concern in many Asian countries, particularly as traditional diets give way to more Western-style eating patterns:

• In China, about 10% of school-age children and adolescents are overweight or obese.
• Japan has seen steady increases in childhood obesity rates since the 1970s.
• India faces a dual burden of undernutrition and rising obesity rates.

Africa

While undernutrition remains a primary concern in many African countries, childhood obesity is an emerging issue, especially in urban areas and more affluent regions:

• In South Africa, about 19% of children ages 2-14 are overweight or obese.
• North African countries like Egypt have seen significant increases in childhood obesity rates.

Factors Contributing to the Global Rise in Childhood Obesity

The worldwide increase in childhood obesity is driven by a complex interplay of factors, many of which are tied to broader societal and economic changes.

Dietary Changes

How have global dietary patterns shifted to contribute to obesity? Several key trends have emerged:

• Increased consumption of processed and ultra-processed foods high in sugar, salt, and unhealthy fats
• Greater reliance on fast food and convenience meals
• Larger portion sizes
• Higher intake of sugar-sweetened beverages
• Reduced consumption of fruits, vegetables, and whole grains

Decreased Physical Activity

Modern lifestyles have led to a reduction in physical activity among children:

• Increased screen time (TV, computers, video games, mobile devices)
• Reduction in active transportation (walking or biking to school)
• Decreased participation in physical education and organized sports
• Safety concerns limiting outdoor play in some areas

Socioeconomic Factors

How do socioeconomic conditions influence childhood obesity rates? Several factors come into play:

• Food insecurity and poverty, which can lead to reliance on cheap, calorie-dense foods
• Limited access to healthy foods in some communities (food deserts)
• Marketing of unhealthy foods to children
• Lack of education about nutrition and healthy lifestyles
• Cultural attitudes toward food and body weight

Genetic and Epigenetic Factors

While lifestyle factors play a major role, genetic predisposition can also influence a child’s risk of obesity. Additionally, emerging research suggests that epigenetic changes – alterations in gene expression that don’t involve changes to the underlying DNA sequence – may also contribute to obesity risk.

Prevention Strategies for Childhood Obesity

Addressing the global childhood obesity epidemic requires a multi-faceted approach involving families, schools, communities, healthcare providers, and policymakers.

Family-Based Interventions

How can families play a role in preventing childhood obesity? Key strategies include:

• Promoting healthy eating habits at home
• Encouraging regular physical activity
• Limiting screen time
• Ensuring adequate sleep
• Modeling healthy behaviors for children

School-Based Programs

Schools can play a crucial role in promoting healthy lifestyles:

• Providing nutritious school meals
• Offering comprehensive physical education programs
• Integrating nutrition education into the curriculum
• Creating opportunities for physical activity throughout the school day
• Eliminating unhealthy food and beverage marketing in schools

Community Initiatives

Communities can support healthy lifestyles for children through various means:

• Developing safe parks and recreational facilities
• Improving access to healthy foods in underserved areas
• Creating walkable neighborhoods and safe routes to schools
• Offering community-based nutrition and physical activity programs

Policy Interventions

What policy measures can help combat childhood obesity? Governments and organizations can consider:

• Implementing taxes on sugar-sweetened beverages
• Regulating food marketing to children
• Improving food labeling to help consumers make informed choices
• Subsidizing healthy foods to make them more affordable
• Developing urban planning policies that promote active lifestyles

Challenges in Addressing Global Childhood Obesity

While the need to address childhood obesity is clear, several challenges complicate efforts to tackle this issue on a global scale.

Cultural Differences

How do cultural factors impact approaches to childhood obesity? Cultural attitudes toward food, body image, and child-rearing practices vary widely across the globe, necessitating culturally sensitive interventions.

Economic Disparities

Economic inequalities both within and between countries can make it difficult to implement uniform strategies for preventing childhood obesity. Low-income communities often face greater barriers to accessing healthy foods and safe spaces for physical activity.

Industry Influence

The food and beverage industry wields significant influence through marketing and lobbying efforts, which can hinder policy changes aimed at promoting healthier diets.

Lack of Global Coordination

While childhood obesity is a global issue, efforts to address it are often fragmented and lack coordinated international action.

Innovative Approaches to Combating Childhood Obesity

As the childhood obesity epidemic continues to evolve, researchers and policymakers are exploring new and innovative approaches to prevention and treatment.

Technology-Based Interventions

How can technology be leveraged to promote healthy behaviors in children? Some promising approaches include:

• Mobile apps for tracking diet and physical activity
• Gamification of healthy lifestyle choices
• Virtual reality experiences to encourage exercise
• Social media campaigns promoting healthy eating

Early Life Interventions

Emerging research suggests that interventions starting in pregnancy and early childhood may be particularly effective in preventing obesity:

• Promoting breastfeeding
• Guiding appropriate introduction of solid foods
• Encouraging healthy sleep habits from infancy
• Supporting maternal health during pregnancy

Environmental Design

How can we design environments that naturally encourage healthy behaviors? Innovative approaches include:

• Redesigning school cafeterias to promote healthier food choices
• Creating active classrooms with standing desks or exercise balls
• Developing urban spaces that encourage walking and outdoor play

Personalized Nutrition

Advances in genetics and microbiome research are opening up possibilities for more personalized approaches to nutrition and obesity prevention tailored to an individual’s unique biological profile.

The Future of Childhood Obesity Prevention

As we look to the future, what directions might childhood obesity prevention efforts take? Several key trends and priorities are likely to shape approaches in the coming years:

Global Collaboration

Recognizing that childhood obesity is a global issue requiring coordinated action, there’s likely to be an increased emphasis on international collaboration and knowledge sharing.

Systems Approach

Future efforts are likely to take a more holistic, systems-based approach that addresses the multiple interconnected factors contributing to childhood obesity.

Focus on Health Equity

There will likely be a growing emphasis on addressing the social and economic disparities that contribute to higher obesity rates in certain populations.

Integration of New Technologies

As technology continues to advance, we can expect to see greater integration of digital tools, artificial intelligence, and big data analytics in obesity prevention efforts.

Emphasis on Early Prevention

Building on emerging research, there’s likely to be an increased focus on interventions starting in pregnancy and early childhood to establish healthy habits from the earliest stages of life.

In conclusion, childhood obesity represents a complex global health challenge that requires sustained, multi-faceted efforts to address. By understanding the scope of the problem, its underlying causes, and promising prevention strategies, we can work towards creating a healthier future for children worldwide. As research continues to evolve and new approaches are developed, there is hope that we can reverse the tide of the childhood obesity epidemic and ensure better health outcomes for generations to come.

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 Causes | Obesity Prevention Source

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!
