A Mechanism Behind the Yo-Yo Effect

 

The yo-yo effect in dieting is something that has been observed for a long time- someone tries to lose weight but gains it all back right after the diet. Recently, scientists have discovered a mechanism behind the yo-yo effect that could help explain why it occurs. By analyzing fat cells from overweight mice and of mice that lost weight through dieting, it was revealed that obesity leads to characteristic epigenetic changes in the nuclei of the fat cells. These changes were found to have remained even after the loss of weight, where the cells remember the overweight state and find it easier to return to it. The mice with those epigenetic markers were able to gain the weight back faster when they resumed a high fat diet. A similar study was carried out on humans and the results were found to be consistent with the mice study.

In my opinion, this is a study that has produced useful information. By discovering a mechanism for why the yo-yo effect occurs on the molecular level, we can better understand how and why it occurs in humans. We could perform more research on this topic in order to potentially develop strategies to prevent it from happening to people who are trying to lose weight and keep it off. This study could have many benefits for many of these people.
