A study in the August 2009 issue of the Journal of the American Dietetic Association states that portion and calorie-controlled meal replacements used in a structured weight-loss program help in medically significant weight loss.
The study compared dieters using the meal replacements and the intensive behavioral program developed by Health Management Resources. Those with diabetes, hypertension or other weight-related medical problems used HMR's medically supervised diet and consumed meal replacements (which comprised HMR Shakes, HMR Entrees, and HMR Nutrition Bars).
The others in the group used HMR's Healthy Solutions Diet and ate meal replacements along with fruits and vegetables. All participants took part in weekly classes, maintained food records, and burned a minimum of 2,000 calories each week through exercise.
Patients on the medically supervised diet lost an average of 43.3 pounds in 19 weeks. Patients on the Healthy Solutions diet lost an average of 37.5 pounds in 18 weeks. These data represent two to three times more weight loss, in less time, compared with published results of any other commercial diet program.
The Centers for Disease Control and Prevention reports a dramatic increase in obesity in the U.S. over the past 20 years, with 66% of Americans now overweight or obese.
