The Claim

In adults at risk for insulin resistance, a 6-week calorie-restricted diet using novel high-protein functional foods results in a 140% greater reduction in HOMA-IR compared to a standard lower-protein diet under identical calorie restriction and similar weight loss.

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

Among adults at risk for insulin resistance, a six-week low-calorie diet with high-protein functional foods reduces insulin resistance 140% more than a low-calorie diet with standard lower-protein foods, even when total calories and weight loss are the same.

See the scientific wording

In adults at risk for insulin resistance, a 6-week calorie-restricted diet using novel high-protein functional foods resulted in a 140% greater reduction in HOMA-IR compared to a standard lower-protein diet, despite identical calorie restriction and similar weight loss, indicating that protein source and distribution may be critical factors for metabolic outcomes.

Why this might work

Eating high-quality protein evenly throughout the day builds more muscle, and more muscle pulls more sugar out of the blood, which lowers the amount of insulin the body needs to keep blood sugar normal.

  1. Study: Use of Novel High-Protein Functional Food Products as Part of a Calorie-Restricted Diet to Reduce Insulin Resistance and Increase Lean Body Mass in Adults: A Randomized Controlled Trial

    When people ate the same number of calories, those who had special high-protein foods got much better at controlling their blood sugar than those who ate regular foods—even though both lost the same amount of weight. This shows what kind of protein you eat matters more than just cutting calories.
