The Claim

In middle-aged adults, a healthy low-carbohydrate diet results in a significantly greater reduction in visceral fat area over 12 months compared to a healthy low-fat diet, with an average difference of 6.3 cm² (95% CI: 0.6–12).

What the research says

Supports is higher

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Over 12 months, middle-aged adults following a healthy low-carbohydrate diet lose more visceral fat than those following a healthy low-fat diet, with an average difference of 6.3 cm².

See the scientific wording

In middle-aged adults, a healthy low-carbohydrate diet leads to significantly greater reduction in visceral fat area over 12 months compared to a healthy low-fat diet, with an average difference of 6.3 cm² (95% CI: 0.6–12), suggesting that dietary carbohydrate restriction may be more effective for targeting metabolically harmful abdominal fat.

Why this might work

When carbs are reduced, the liver switches to burning fat for energy and stops making new fat, which causes the body to break down stored fat around the organs more than when eating less fat.

  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 who ate fewer carbs lost more of the dangerous fat around their organs than those who ate less fat, and the difference was real and measurable after a year.
