Feature Worldwide obesity has tripled since 1975, with over 650 million obese and 1.9 billion overweight people in 2016, according to the World Health Organization (WHO). added, is that these highly restrictive approaches eventually fail because you have a strong metabolic pushback towards the set point � the more drastic the diet the more intense the pushback � and many people are simply not able to stick to the strict regimen for long periods. Regardless of the type of diet, non-compliance is often driven by tough life events, stressed Dr Michael D. �ensen, an obesity expert at the Mayo Clinic. �My patients often fail to achieve their goal for weight-loss because of life problems,” he told Global Health Asia- �aci�c. �I’m not saying it’s their fault, they try to lose weight and then their partner gets cancer, they get stressed out from work, or something else happens that disrupts their plans to lose weight.� Poor socio-economic conditions are also strong predictors of obesity. Not everyone has the same degree of food security or can afford to buy and prepare healthy food, so these are extra challenges on top of the biological pushback that make long-term weight loss even harder, said Dr Dushay. Coupled with the globalisation of unhealthy lifestyles, all these factors have contributed to soaring rates of excess weight gain. Worldwide obesity has tripled since 1975, with over 650 million obese and 1.9 billion overweight people in 2016, according to the World Health Organization (WHO). Over the same period, the prevalence of overweight and obesity in children and adolescents more than quadrupled and stood at �40 million in 2016. �ids and teenagers in low- and middle-income countries are the most vulnerable because they’re more exposed to high-fat, high-sugar, and high-salt foods that are cheap but promote weight gain and lack essential nutrients, highlighted the WHO. This explosive rise has been described by the WHO as an obesity epidemic, meaning the condition can’t simply be blamed on people’s choices. “Obesity is not a temporary condition where people can easily lose significant amounts of weight and keep it off over time,� stressed Dr �uhl. �And that’s one of the reasons we’ve seen the American Medical Association classify obesity as a chronic disease.� Well-being isn’t the result of body size Despite the strong biological and environmental headwinds, people who are committed to eating wholesome foods and doing physical activity on a regular basis can definitely lose weight. “Those people are much more likely to succeed than people who say, ‘for the next two months I’m only going to have a liquid diet or cut cheese out,’” said Dr �ensen. “I actually don’t use the term ‘diet’ when I talk to my patients because it implies something temporary. I prefer the term �changing eating habits,’� he said. “I usually tell my patients: are you willing to make permanent changes to your eating habits? Even one small thing at a time you’re willing to change forever can reduce your weight and improve your health.� A comprehensive healthy lifestyle, including not only a high quality diet and exercise but also good sleep and stress management habits, can help even very large-size people improve quality of life and lose a significant amount of weight, said Dr Dushay, but that doesn’t necessarily mean everyone will slim down to their ideal body size. “The scale moves in very frustrating and individualised ways that we don’t totally understand, but if people focus on improving their diet, exercise, sleep, and stress levels, they could feel significantly better without having to rely solely on a number on the scale to tell them that they are healthier,” she said, noting that many of her patients are surprised by how empowered they feel when they improve their health to the point that they can go up a �ight of stairs, walk a mile, or play with their children or grandchildren without being out of breath. The bottom line is that the goal is to feel better rather than chase a number on a scale because excess weight doesn’t always equate to poor health. Despite what many think, the body mass index (�MI), the measure used to establish whether you’re overweight or obese by dividing your weight by the square of your height, isn’t an accurate metric of overall health. �Obesity is a very heterogeneous disease. �ou can find 10 people with the exact same �MI and they can be in 10 different states of health, from very poor to very good,” explained Dr Dushay, noting that someone who is slim but totally stressed out with terrible eating and sleeping habits is less healthy than another with a higher �MI who follows a good diet, does regular physical activity, and sleeps well. People with obesity who exercise can be in good health even if they don’t lose a lot of weight 52 SEPTEMBER-OCTOBER 2020 GlobalHealthAsiaPacific.com
