The Claim

Daily consumption of 10 grams of lupin protein for five weeks in adolescent boys with overweight or obesity is associated with a significant reduction in glucose-dependent insulinotropic polypeptide (GIP) and ghrelin levels.

In plain English

In adolescent boys with overweight or obesity, consuming 10 grams of lupin protein daily for five weeks is associated with lower levels of the hormones GIP and ghrelin.

See the scientific wording

Daily consumption of 10 grams of lupin protein for five weeks in adolescent boys with overweight or obesity is associated with a significant reduction in glucose-dependent insulinotropic polypeptide (GIP) and ghrelin levels, suggesting a potential role in modulating postprandial satiety and insulin secretion.

Why this might work

Lupin protein is broken down by gut bacteria to produce butyrate, which tightens the gut lining and stops inflammatory molecules from entering the blood. This reduces inflammation in fat tissue, which lowers the signals that tell the body to release hunger hormones and insulin-stimulating hormones. As a result, the body produces less ghrelin and GIP, making the person feel fuller longer and reducing the need for high insulin output after meals.

  1. Study: Functional Soy and Lupin Protein-Based Beverages Modulate Gut Microbiome and Attenuate Metabolic Dysregulation in Adolescent Boys with Overweight and Obesity

    The study gave overweight teen boys a daily drink with 10 grams of lupin protein for five weeks, and their hunger hormones (GIP and ghrelin) went down — meaning they likely felt fuller after eating. This matches exactly what the claim said.
