The Claim

In middle-aged adults with insulin resistance (defined as HOMA-IR > 2.6), a low-carbohydrate high-fat diet leads to significantly greater reductions in android and visceral fat compared to a calorie-restricted low-fat diet; this differential effect is not observed in insulin-sensitive individuals, indicating that insulin resistance status modifies the body composition response to dietary carbohydrate restriction.

Supports is higher

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

In plain English

If you're middle-aged and your body doesn't respond well to insulin, cutting carbs and eating more fat might help you lose belly fat better than a low-fat diet. But if your body handles insulin normally, both diets work about the same for fat loss.

See the scientific wording

Among middle-aged adults with insulin resistance (HOMA-IR > 2.6), a low-carbohydrate high-fat diet is associated with significantly greater reductions in android and visceral fat compared to a calorie-restricted low-fat diet, while no such difference is observed in insulin-sensitive individuals, suggesting insulin resistance status modifies the body composition response to dietary carbohydrate restriction.

  1. Study: Greater Loss of Central Adiposity from Low-Carbohydrate versus Low-Fat Diet in Middle-Aged Adults with Overweight and Obesity

    The study found that middle-aged people with insulin resistance lost more belly fat on a low-carb, high-fat diet than on a low-fat diet, which matches the claim.
