The science behind it goes back to our caveman roots
By Ella Alexander
In the least surprising news of the day, it's been confirmed that yo-yo dieting leads to inevitable weight gain.
A study, published in the journal Evolution, Medicine and Public Health, found that repeated diets trigger a caveman response to famine that causes the brain to send out signals of food scarcity – telling the body to store more fat in case there are future food shortages.
According to the Telegraph Reporters, the research was based on observations of nature. Scientists devised a mathematical model in a simulated animal that doesn't know when to expect its next meal. They found that when food is low on the ground, animals seize any opportunity to put on weight.
"Surprisingly, our model predicts that the average weight gain for dieters will actually be greater than those who never diet," said the lead researcher Dr Andrew Higginson, from the University of Exeter.
"This happens because non-dieters learn that the food supply is reliable so there is less need for the insurance of fat stores."
He added that the best way to lose weight was via the traditional route – exercise regularly and eat in moderation.
"The best thing for weight loss is to take it steady," said Dr Higginson. "Our work suggests that eating only slightly less than you should, all the time, and doing physical exercise is much more likely to help you reach a healthy weight than going on low-calorie diets."
So put that juice down and enjoy the indulgences of Christmas and then the next holiday...
