Given that all participants in the study were overweight and “healthy”, what was not studied, and could have been very useful, was what was the impact of the two diets on participants’ blood sugars (HbA1c), insulin levels, and on some measure of inflammation. It is possible that there could have been little difference in weight loss between the two diets but big differences in the impact on risk factors related to diabetes.
The most important consideration of any diet is finding one that you can stick with for the long haul. While many diets promise that you'll quickly shed pounds in the beginning, the truth is that reining in your eating will almost always result in quick, initial weight loss regardless of what program you decide to try. The trick is to find a program that -- after that first couple of weeks -- you can adhere to as your weight loss slows to more realistic levels. Experts say that people who make diets a lifestyle rather than just a "diet," while setting a goal of losing a pound or so a week, are more apt to keep the weight off over the long term.
What's more trustworthy than a diet built by experts from the Mayo Clinic? Created by doctors, nutritionists, and all-star chefs, the plan has a few phases: In the first, you should lose 6 to 10 pounds in two weeks. After that, you can expect to lose 1 to 2 pounds a week until you reach your goal weight. You're also given plenty of resources and advice to help you keep the weight off.
