More than 500 million people in this planet are obese…
Here is the situation. Half a billion human worldwide are obese… Okay, we are not just talking about the posture or body image here. We are talking about the side effect of having more weight, how much money that each individual spent to lose weight and how much money that is invented to study how to make people leaner. This is a serious world health problem.
What we have done to handle this problem? Well, almost everything. Diet, exercise, lifestyle intervention with behavioral changes, pills, surgery, and liposuction are some example how bad we want our society to be healthy and lean these days. But what do we got? This prevalence of obesity is much even higher, and the numbers are doubled in past 30 years.
Eat less, move more…
That is not so easy. Although expert panels of World Health Organization have recommended obese and overweight individuals to lose weight at least 10% from their current weight. Lifestyle modification including diet, exercise and behavior therapy are considered as the first option to achieve this goal. It is necessary to address that weight loss program using life style modification including diet, exercise and behavior therapy is not always successful. Study of peer-literature publications, reviews and meta-analysis by Yaskin et al. showed that this intervention was marginally effective to induce weight loss in overweight and obese individuals.
Obese individuals who join this weight loss program could loss some weight. However, there is a group of obese who can not lose weight, or even after they lost some weight there is still a possibility for weight rebound. This devastating phenomenon then fails the whole process that has been initiated before.
Currently, academia and people who work in the research field tried to find out why this phenomenon happened. Why some people are easily lost weights while the other not? Why obese people are tend to increase their weight even more after weight loss. Are some genes responsible or activation of certain protein are blunted in this process. Lets hope that we can find something good for the future, otherwise we can only said that this is might be part of human evolution…
