Introduction
• Globally, there are more than 1 billion overweight adults, at least300 million of them obese.
• Obesity and overweight pose a major risk for chronic diseases,including type 2 diabetes, cardiovascular disease, hypertension andstroke, and certain forms of cancer.
• The key causes are increased consumption of energy-dense foodshigh in saturated fats and sugars, and reduced physical activity.
Obesity and Overweight
Overweight and Obesityare defined as excessive fat accumulation that may impair health.
• Body mass index (BMI) is a simple index of weight-for-height that iscommonly used to classify overweight and obesity in adults.
For adults, WHO defines overweight and obesity as:
• overweight is a BMI greater than or equal to 25; and
• obesity is a BMI greater than or equal to 30.
BMI-most useful measure of overweight and obesity.
However, it should be considered a rough guide.
BMI
Overweight and Obesity
Some stats about overweight and obesity
Some recent WHO global estimates shows:
• In 2016, more than 1.9 billion adults aged 18 years and older wereoverweight. Of these over 650 million adults were obese.
• In 2016, 39% of adults aged 18 years and over (39% of men and 40%of women) were overweight.
• Overall, about 13% of the world’s adult population (11% of men and15% of women) were obese in 2016.
• Worldwide obesity nearly tripled between 1975 and 2016.
Some indications on Overweight and Obesity
Common Consequences of Overweight and Obesity
Raised BMI is a major risk factor for non-communicable diseases such as:
• cardiovascular diseases (mainly heart disease and stroke), which were the leading cause of death in 2012; diabetes;
• musculoskeletal disorders (especially osteoarthritis – a highly disabling degenerative disease of the joints);
• some cancers (including endometrial, breast, ovarian, prostate, liver, gallbladder, kidney, and colon).
The risk for these non-communicable diseases increases, with increase in BMI.
Obesity Vs Overweight
Common Consequences of Overweight and Obesity
• Childhood obesity is associated with a higher chance of obesity,premature death and disability in adulthood.
• But in addition to increased future risks, obese children experiencebreathing difficulties, increased risk of fractures, hypertension, earlymarkers of cardiovascular disease, insulin resistance andpsychological effects.
Consequences of Overweight and Obesity
Co-existing under-nutrition and obesity
Many low- and middle-income countries are now facing a "doubleburden" of disease.
• These countries continue facing problems of infectious diseases andundernutrition.
• They also experience a rapid upsurge in non-communicable diseaserisk factors such as obesity and overweight, particularly in urban.
• It is common to find undernutrition and obesity co-existing within thesame country, the same community and the same household.
Co-existing under-nutrition and obesity
• Children in low- and middle-income countries are more vulnerable toinadequate pre-natal, infant, and young child nutrition.
• These children are exposed to high-fat, high-sugar, high-salt, energy-dense, and micronutrient-poor foods.
• These dietary patterns, in conjunction with lower levels of physicalactivity, result in sharp increases in childhood obesity whileundernutrition issues remain unsolved.

Yes: Overweight and obesity can be reduced
Overweight, obesity and related non-communicable diseases, are largelypreventable.• Supportive environments: by making the choice of healthier foods and regular
physical activity the easiest choice.• thereby preventing overweight and obesity.
At the individual level, people can:• limit energy intake from total fats and sugars;• increase consumption of fruit & vegetables, and legumes, whole grains & nuts; • engage in regular physical activity.
Yes: Overweight and obesity can be reduced
• Individual responsibility can only have its full effect where peoplehave access to a healthy lifestyle.
• Therefore, regular physical activity and healthier dietary choicesavailable, affordable and easily accessible to everyone, particularly tothe poorest individuals.
• An example is a tax on sugar sweetened beverages.
Yes: Overweight and obesity can be reduced
Food industry can play a significant role in promoting healthy diets by:
• reducing the fat, sugar and salt content of processed foods;
• ensuring that healthy and nutritious choices are available andaffordable to all consumers;
• restricting marketing of foods high in sugars, salt and fats; and
• ensuring the availability of healthy food choices and supportingregular physical activity practice in the workplace.
WHO’s role
"WHO Global Strategy on Diet, Physical Activity and Health”
Accordingly, actions needed
• to support healthy diets and regular physical activity.
• to improve diets and physical activity patterns at the population level.
• to reduce unhealthy diet and physical inactivity.
WHO also developed "Global Action Plan for the Prevention andControl of Non-communicable Diseases 2013-2020"

Effective Weight Management(EWM)
Effective weight management for individuals and groups at risk of developingobesity involves a range of long-term strategies.
• These include prevention, weight maintenance, management of co-morbidities and weight loss.
• They should be part of an integrated, multi-sectoral, population-basedapproach, which includes environmental support for healthy diets andregular physical activity.
Key elements of EWM:
• Creating supportive environment that promote the availability andaccessibility of a variety of low-fat, high-fibre foods, and that provideopportunities for physical activity
EWMPromoting healthy behaviours to encourage, motivate and enable individualsto lose weight by:
• eating more fruit and vegetables, as well as nuts and whole grains;
• engaging in daily moderate physical activity for at least 30 minutes;
• cutting the amount of fatty, sugary foods in the diet;
• moving from saturated animal-based fats to unsaturated vegetable-oilbased fats.
Managing existing burden of obesity and associated conditions throughclinical programmes to ensure to lose weight or avoid further weight gain.
