Research contradict widely held research

A new study suggests that exercise plus diet is not the most effective means to loose weight. 

Dieting and exercising can help weight loss.   But dieting alone can be as effective, according to a new study published in a recent issue of Journal of Clinical Endocrinology and Metabolism.

Weight loss occurs in a person who reduces intake of calories in his diet and or increases energy expenditure through physical exercise.

"What we found was that it did not matter whether a reduction in calories was achieved through diet or burned everyday through exercise," Dr. Leanne Redman of the Pennington Biomedical Research Center in Baton Rouge, Louisiana.

In the 6-month study of thirty-five overweight but otherwise healthy adults, 12 were assigned to reduce their calorie intake by 25 percent.   12 were assigned to diet plus exercise, reducing calorie intake by 12.5 percent and increasing their exercise by 12.5 percent.   The remaining 11 were not asked to change any thing in terms of diet and physical activity.

Yes, dieting alone can be effective for weight loss.  However, numerous prior studies have shown the benefits, both in terms of weight reduction and health, of exercise.
