Everyday patients or even friends / family members, reach out saying that they are doing everything they can to lose weight with lifestyle measures alone without success. Many times, if they had lost weight with these changes before, they are not working anymore. This brings us to THE realisation that something doesn’t not quite add up. It became abundantly clear to me over and over again that for many patients lifestyle alone was not going to treat their obesity.
The key reason behind this is metabolic adaptation. So what is metabolic adaptation?
Metabolic adaptation is as you continue to lose weight, metabolic rate goes down disproportionate to the amount of weight you lose. We all know caloric deficit is the key to losing weight. Metabolic adaptation makes it very hard to stay in enough calorie deficit to continue to lose weight or even to keep off the weight one had previously lost with the exact same things that were working before. The neurohormonal basis for this adaptation is increased production of hunger producing hormone ghrelin and reduced levels of leptin hormone that helps us stay full.
That is the exact reason why many people would require medication or surgery for continued meaningful weight loss.
So should we stop eating healthy and doing physical activity? We still need to eat healthy and exercise to reap the metabolic health benefits of a healthy diet and exercise in terms of preserving muscle mass, strengthening our bones, lower the risk of high blood pressure, improved heart health, lower risk of many cancers and diabetes among so many other benefits.
