Obese women with resistance to insulin lose more weight after three months on a diet with low carbohydrates than being on a traditional diet low on fat with the same number of calories, as per a new study.
Study’s lead author, Raymond Plodkowski, chief of endocrinology, nutrition and metabolism at the University Of Nevada School Of Medicine, Reno, remarked that the typical diet recommended by physicians for losing weight is a low-fat diet but results of the study suggest that not all individuals benefit from this form of diet.
From in.news.yahoo.com:
People with insulin resistance, a common precursor for Type 2 diabetes, metabolize carbohydrates, or “carbs,” abnormally, which may affect their rate of weight loss. For them, Plodkowski said, “the lower-carb diet is more effective, at least in the short term.”
At 12-weeks, the study funded by Jenny Craig and using prepared calorie-controlled meals as part of a behavioral weight loss program, found that the insulin resistant women on a lower-carb diet lost 3.4 pounds more than those on a low-fat diet.
Forty-five obese women between the ages of 18 and 65 years participated in the study, and all had insulin resistance, as found by fasting blood levels of insulin. The researchers randomly assigned the women to either a low-fat or lower-carb diet.
The groups did not differ significantly in average body weight, the authors reported. On average, women in the low-fat diet group weighed 213 pounds, while women in the other group weighed 223 pounds.
The composition of the low-fat diet was 60 percent of calories from carbs, 20 percent from fat and 20 percent from protein. Although the lower-carb diet also had 20 percent of calories from protein, it had 45 percent from carbs and 35 percent from primarily unsaturated fats, such as nuts. Menus included a minimum of 2 fruits and 3 vegetable servings a day.
The results were presented at The Endocrine Society’s 92nd Annual Meeting in San Diego.
