The Claim

In non-obese Japanese men with type 2 diabetes, a 3-month moderate low-carbohydrate diet reduced visceral adipose tissue by a statistically significant amount, and subcutaneous fat also decreased, with only visceral fat loss showing a statistically significant correlation with reduced carbohydrate intake.

Source: Association of decrease in carbohydrate intake with reduction in abdominal fat during 3-month moderate low-carbohydrate diet among non-obese Japanese patients with type 2 diabetes.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

In non-obese Japanese men with type 2 diabetes, following a moderate low-carbohydrate diet for three months led to a measurable reduction in visceral fat, and this reduction was directly linked to lower carbohydrate intake. Subcutaneous fat also decreased, but not in a way that correlated with carbohydrate reduction.

See the scientific wording

In non-obese Japanese men with type 2 diabetes, a 3-month moderate low-carbohydrate diet reduced visceral adipose tissue by a statistically significant amount, while subcutaneous fat also decreased, but only visceral fat loss showed a significant correlation with reduced carbohydrate intake.

Why this might work

When less sugar and starch are eaten, the body makes less insulin. Lower insulin tells fat cells around the organs to break down stored fat and release it into the blood. This happens more in fat around the organs than under the skin, so the belly fat goes down more than the fat under the skin.

  1. Study: Association of decrease in carbohydrate intake with reduction in abdominal fat during 3-month moderate low-carbohydrate diet among non-obese Japanese patients with type 2 diabetes.

    In a study of non-obese Japanese men with diabetes, eating fewer carbs for three months led to less fat around their organs, and the more carbs they cut, the more fat they lost. Fat under the skin also went down, but not because of eating fewer carbs.
