The Claim

A healthy low-carbohydrate diet leads to greater visceral fat loss compared to a healthy low-fat diet over a 12-month period in middle-aged adults, independent of total weight loss, indicating that macronutrient composition affects fat distribution beyond overall calorie balance.

Cause and effect
1 study reviewed
In plain English

Over 12 months, middle-aged adults on a healthy low-carbohydrate diet lose more visceral fat than those on a healthy low-fat diet, even when total weight loss is the same, showing that the proportion of carbohydrates and fats in the diet influences where fat is lost.

See the scientific wording

A healthy low-carbohydrate diet results in greater visceral fat loss than a healthy low-fat diet over 12 months in middle-aged adults, independent of total weight loss, suggesting that macronutrient composition influences fat distribution beyond overall calorie balance.

Why this might work

When carbohydrate intake is low, the body produces less insulin, which tells fat cells around the organs to release stored fat into the blood. This fat is then burned for energy instead of being stored, leading to more fat loss around the organs compared to when more carbohydrates are eaten.

  1. Study: Effect of low-carbohydrate vs low-fat diet intervention on visceral fat estimated from dual energy X-ray absorptiometry in a 12-month randomized controlled trial.

    People on a low-carb diet lost more fat around their organs than those on a low-fat diet, even when both groups lost the same amount of total weight — meaning what you eat affects where your body loses fat, not just how much.
