The Claim

In adults with non-alcoholic fatty liver disease, a 12-week calorie-restricted intermittent fasting (5:2) diet and a low-carbohydrate high-fat diet produce similar reductions in total abdominal fat (14–18%) and visceral adipose tissue (17–21%), indicating that overall weight loss, rather than macronutrient composition, is the primary driver of fat loss in this population.

How it works
1 study reviewed
In plain English

In adults with non-alcoholic fatty liver disease, two different diets—intermittent fasting and low-carbohydrate high-fat—result in the same amount of fat loss in the abdomen and around internal organs, even though the diets have very different amounts of carbs and fats. The amount of weight lost, not the type of diet, determines how much fat is reduced.

See the scientific wording

In adults with non-alcoholic fatty liver disease, a 12-week calorie-restricted intermittent fasting (5:2) or low-carbohydrate high-fat diet results in similar reductions in total abdominal fat (approximately 14–18%) and visceral adipose tissue (approximately 17–21%), despite markedly different macronutrient compositions, suggesting that overall weight loss, not diet composition, is the primary driver of fat loss in this population.

Why this might work

When the body takes in fewer calories than it needs, it breaks down stored fat in belly and liver areas to use as energy, and this happens whether the calories come from cutting carbs or skipping meals — the total energy shortage is what triggers the fat loss.

  1. Study: Macronutrient composition and its effect on body composition changes during weight loss therapy in patients with non-alcoholic fatty liver disease: Secondary analysis of a randomized controlled trial.

    For people with fatty liver disease, whether they eat fewer carbs or skip meals two days a week, they lose about the same amount of belly and liver fat as long as they lose the same amount of weight. What matters most is losing weight, not what foods they eat.
