A recent study published Feb 2009 in the New England Journal of Medicine discusses the differences between common weight loss diets. This study was conducted between 2004 and 2007, includes 800 overweight/obese adults (30 to 70 years old). The participants were randomly assigned to low carbohydrate diet, low fat diet, or high protein diet. All participants performed 90 minutes of exercise per week. The majority of the weight loss occurred during the first 6 months with all the diets. All of the diets lowered cardiovascular and diabetes risk factors. The low fat and low carbohydrate diets lowered LDL (bad or “lousy” ) cholesterol levels more than the high protein diet. The low carbohydrate and high protein diets caused more weight loss at 6 months but at 1 year weight loss was the same among all the different diets. This study showed that all of these diets were equally successful in promoting weight loss. Calorie restriction (with any of these diets) AND routine exercise are the most important components of a successful weight loss program! You need to pick a diet that will work for you and remember to incorporate a regular exercise routine.
