Is Yo-yo Dieting Better than Always being Overweight?
A new study suggests that yo-yo dieters may be healthier and live longer than those who stay obese.
Yo-yo dieting seems generally frowned upon by people, including those in the medical community. Gaining, losing and regaining weight is thought to be damaging to health over time. It is also thought that it could ruin your body’s ability to control weight.
This is reflected in the conventional wisdom that everyone just seems to have. You always hear ‘lose weight slowly and steadily‘ or ‘make a lifestyle change’. These are not easy things to do and can be discouraging to people who want to lose weight…so they may not even try.
But the question remains…is it better to be overweight and stay over weight than to have your weight fluctuate?
The recent study used thre groups of mice. One group switched between a high-fat and a low-fat diet every four weeks, another group ate only a low-fat diet and the remaining group ate a high-fat diet.
The yo-yo dieting mice lived about 25 percent longer than the obese animals eating a high-fat diet. They also had better blood glucose levels — poor blood glucose levels could indicate a problem such as diabetes.
This research suggests that yo-yo dieting may be preferable to remaining obese and never dieting at all. It doesn’t say that yo-yo dieting is preferable to staying a healthy weight and eating a healthy diet, which is obviously the best choice.
It is desirable to study the effects of yo-yo dieting on humans; however, such an experiment is quite difficult to control.
Even if it is not possible to extend the study to humans, the researchers hope that this study will encourage people who are trying to lose weight for health reasons to never give up.
