Can Exercise Suppress the Occurrence of Weight Regain?

Published:September 18th, 2011

Were you able to lose weight effectively? Are you afraid to regain those pounds you shed? Do you ever wonder how you can achieve a sustained weight loss?

A  new study conducted by a group of researchers from the University of Colorado in Denver and published in the June 2011 issue of the American Journal of Physiology reveals that exercise may be the big “IT” to the prevention of weight regain in patients who had successfully lost some weight.

Exercise is known to improve energy balance, enhance fuel and energy utilization and increase nutrient utilization within the body. In this particular study, the researchers collected obese rats and let them had a calorie-restricted, low fat diet to induce weight loss. They have noted that these rats were able to maintain weight reduction for a period of six weeks even without exercise. However, after, the initial six weeks, they have noted that those sedentary rats began to regain the amount of weight they have lost even when they maintained their present diet. Nevertheless, those who were having regular exercise continued to lose weight because exercise continued to cause energy imbalance, reduced appetite, and increased energy requirements. They have also noted that the dietary fats being taken by exercising rats are being trafficked away from fat storage in the adipose tissues to greater fat oxidation.

Thus, they have concluded that increased physical activity is the best way to prevent weight regain in patients who had successfully shed pounds. Without this important key, weight regain is expected to occur.
