A new study has found that fat tissue retains a kind of memory of obesity even after weight loss, which increases the likelihood of weight gain again.
The study, published in the journal Nature, sheds light on the ‘Yu-Yu effect’ (sudden weight gain after a diet) in which people lose weight and then gain it back.
According to researchers at ETH Zurich in Switzerland, the study results could help in future weight control strategies.
A clear goal in the treatment of obesity is to change lifestyle so that weight can be reduced and secondary complications such as diabetes or liver disease can be avoided.
Usually, people change their diets and make exercise a part of their daily routine to deal with obesity. While some people temporarily lose weight, but later gain it back.
Researchers suspect that this may be due to the body’s fat tissue storing fat. However, the exact mechanism behind this is still unclear.
In a new study, scientists found that human and mouse fat tissue shows changes in genetic activity that persist even after significant weight loss.
