The Claim

In overweight adults with type 2 diabetes, a 24-week dietary intervention combining a high-protein, low-fat diet with moderate exercise produces no statistically significant difference in body composition changes compared to a higher-carbohydrate diet, despite equivalent weight loss in both groups.

Source: A randomised trial comparing low-fat diets differing in carbohydrate and protein ratio, combined with regular moderate intensity exercise, on glycaemic control, cardiometabolic risk factors, food cravings, cognitive function and psychological wellbeing in adults with type 2 diabetes: Study protocol.

Description
1 study reviewed
In plain English

Among overweight adults with type 2 diabetes, a diet high in protein and low in fat combined with moderate exercise results in the same changes in body composition as a higher-carbohydrate diet after 24 weeks, even when both diets lead to the same amount of weight loss.

See the scientific wording

In overweight adults with type 2 diabetes, a 24-week dietary intervention combining a high-protein, low-fat diet with moderate exercise does not show statistically significant differences in body composition changes compared to a higher-carbohydrate diet, despite both groups achieving similar weight loss.

Why this might work

When two groups lose the same amount of weight by eating fewer calories, their bodies break down fat and muscle in similar proportions, no matter if they eat more protein or more carbs, because the total energy shortage determines how the body uses its stored fuel.

  1. Study: A randomised trial comparing low-fat diets differing in carbohydrate and protein ratio, combined with regular moderate intensity exercise, on glycaemic control, cardiometabolic risk factors, food cravings, cognitive function and psychological wellbeing in adults with type 2 diabetes: Study protocol.

    This study gave two groups of overweight people with diabetes different diets — one with more protein and one with more carbs — but both ate fewer calories and exercised the same. It’s measuring whether one diet helps lose more fat or keep more muscle than the other, and the results will tell us if they’re about the same.
