Combining diet and exercise best strategy to reduce type 2 diabetes risk

7 May 2015

Although many people think the benefits of exercise, calorie restriction and weight loss are interchangeable, a new study has suggested this is not the case when it comes to managing type 2 diabetes.

A new paper, published in Diabetes Care, enrolled sedentary, overweight, middle-aged men and women and assigned each to one of three groups. Each group was designed to reduce weight by six to eight per cent through either calorie restriction, exercise or a combination of both.

Saint Louis University associate professor of nutrition and dietetics Edward Weiss and colleagues found that both exercise and calorie restriction had positive effects on insulin sensitivity. 

However, the group that did both saw two times the improvement in insulin sensitivity than either of the single-approach groups.

"Your blood sugar may be perfectly normal, but if your insulin sensitivity is low, you are on the way to blood sugar issues and, potentially, Type 2 diabetes," Dr Weiss said.

The study suggests that combining exercise and calorie restriction is the best way to reduce type 2 diabetes risk.
