A Different Approach to Getting Fit

Sunday, July 5th, 2009

Many weight-loss programs propose changes in the propositions of the three main food groups–proteins, fats and carbohydrates. How effective are these programs? The Harvard School of Public Health in Boston, Massachusetts, placed 811 overweight adults on four different diets over a two-year period. The diets contained varying percentage of fat, protein, and carbohydrate.

After six months, all four diet groups averaged a six-kilogram weight loss, or 7 percent of their original weight, which ever diet they were on. All again began to regain weight after 12 months. After two years, the average weight loss was about four kilograms for all groups. Earlier studies had claimed that higher protein intake reduced appetite and sustained muscle mass better during weight loss. The Harvard researchers’ conclusion: A diet program’s benefits result from the degree to which people stick with them, not from any specified energy reduction formula.
