The Claim

Daily consumption of 28–42 g of walnuts by overweight and obese adults on a calorie-restricted diet has no significant effect on self-reported satiety, hunger, or fullness compared to a standard reduced-energy-density diet.

Description
1 study reviewed
In plain English

In overweight and obese adults following a calorie-restricted diet, eating 28–42 grams of walnuts daily does not change how full, hungry, or satisfied they feel compared to eating other foods with similar calorie density.

See the scientific wording

In overweight and obese adults on a calorie-restricted diet, daily walnut consumption (28–42 g) does not significantly alter self-reported satiety, hunger, or fullness compared to a standard reduced-energy-density diet, indicating that walnuts do not enhance appetite control through subjective satiety mechanisms during weight loss.

Why this might work

Eating walnuts adds specific fats to the body that lower bad cholesterol and reduce blood pressure, but these changes do not affect how full or hungry a person feels during dieting.

  1. Study: Walnut consumption in a weight reduction intervention: effects on body weight, biological measures, blood pressure and satiety

    When people ate walnuts every day while dieting, they didn’t feel fuller or less hungry than people eating other low-calorie foods — so walnuts don’t help with weight loss by making you feel less hungry.
