Y is for yo-yo dieting
Oprah made the condition famous; that of constantly losing and subsequently regaining weight. Not only is this pattern of weight loss and weight gain discouraging to those who experience it, constant losses and regains are hazardous to your health. Research shows that adults who experience frequent fluctuations in body weight are at a higher risk of dying from cardiovascular disease.
The next time you see a product that guarantees quick weight loss, save your money. Instead replace the latest fad diet or gimmick with a slow, but permanent, weight loss program that includes regular exercise.
Unfortunately only about 10% of all people who begin a weight loss program without exercise are able to lose the desired weight. Even more alarming is the fact that only 5 in every 100 who lose the weight are able to keep it off.
The body is highly resistant to permanent weight changes through caloric restriction alone. In fact the body reads drastic cuts in energy intake as a reason to preserve fat, our richest source of stored energy. A remanent of more primitive times, the body’s plan is to reduce energy expenditure and fat consumption in case food does not show up on the horizon (literally) for a few days or weeks.
A number of weight loss programs recommend exercise or physical activity along with caloric restrictions. The aim is to gradually lose fat, while maintaining energy-consuming muscle mass. Such lifestyles changes must, however, be gradual and permanent. If the person discontinues diet or exercise the cycle of weight loss and weight gain begins.
Be sure to include physical activity in your daily routine – walking is by far the most convenient, and do some more vigorous exercise a couple of times a week once you are ready. Don’t delay – start today.
