The Claim

In morbidly obese adults undergoing bariatric surgery, the presence of type 2 diabetes has no significant effect on the magnitude of weight loss, fat mass reduction, or fat-free mass loss during an 8-day very low-calorie diet.

Description
1 study reviewed
In plain English

Among morbidly obese adults who have had bariatric surgery, those with type 2 diabetes lose the same amount of weight, fat, and lean tissue as those without diabetes when following an 8-day very low-calorie diet.

See the scientific wording

In morbidly obese adults undergoing bariatric surgery, the presence of type 2 diabetes does not significantly alter the magnitude of weight loss, fat mass reduction, or fat-free mass loss during an 8-day very low-calorie diet, suggesting that diabetic status does not strongly modulate short-term body composition responses to caloric restriction.

Why this might work

When calories are drastically reduced, the body breaks down fat and muscle tissue at the same rate whether or not a person has type 2 diabetes, because insulin levels drop sharply and the body relies on stored energy the same way in both groups.

  1. Study: Very low-calorie diet in candidates for bariatric surgery: change in body composition during rapid weight loss

    In severely obese people getting ready for surgery, whether they have type 2 diabetes or not, they lost about the same amount of fat and muscle during an 8-day super-low-calorie diet.
