Study Suggests Diets Are Not One-Size-Fits-All
A recent study suggests that not all diets are made equal. Researchers from the University of Copenhagen found that the efficacy of a diet may rely more on an individual’s insulin sensitivity than on the diet itself.
The researchers examined data from three randomized clinical trials that were conducted in eight European countries. The studies examined the effects on weight of high protein diets, high fat diets, low carbohydrate diets, low carb but high glycemic index diets, high carb and high glycemic index diets, and high fiber and whole grain diets. The studies results were then classified according to the participant was pre-diabetic, diabetic, or had normal glycemic control.
The researchers found that pre-diabetic participants were more likely to gain weight when they consumed a high-glycemic load diet. However, they lost weight when they consumed a low-glycemic load diet or a high fiber and whole grains diet, regardless of whether or not they restricted calories.
Participants with diabetes were more likely to lose weight if they followed a high-fat, low-carbohydrate diet than if they followed a low-fat, high-carb diet. Participants with normal glycemic levels were more likely to lose weight on a low-fat, high-carbohydrate diet.
The study was published online ahead of print on July 5, 2017, in the American Society for Nutrition.
Losing weight has been linked to a number of health benefits, including improving sleep quality, better mood, improved sex drive, decreased joint pain, and decreased risk of cardiovascular disease.
