Are You Hard-Wired to Fail at Dieting?

Are You Hard-Wired to Fail at Dieting?
 

If you tend to quickly regain the pounds you’ve lost though changing your eating and exercise habits, you might be biologically doomed to fail at long-term weight loss. According to a new study published in the International Journal of Obesity, eating a high-fat diet over a long period of time damages a biomechanical process in which the stomach tells the brain that it’s full. Even when you return to a healthy weight, the mechanism does not correct itself, and you’re likely to pack the pounds back on.

The study was performed on two groups of mice. One group ate a low-calorie diet made up of 7% fat; the other group ate a high-calorie diet that included 60% fat. After 12 weeks, obese mice were fed a normal diet and although they lost weight at first, they went on to increase their food intake, matching it to the high-fat diet.

“The stomach’s nerve response does not return to normal upon return to a normal diet,” says study author Dr. Amanda Page. “This means you would need to eat more food before you felt the same degree of fullness as a healthy individual.”

Adds Page: “We know that only about 5% of people on diets are able to maintain their weight loss, and that most people who’ve been on a diet put all of that weight back on within two years.” 

Further research will look at whether this nerve damage can be reversed.
