The Claim

Daily consumption of 10 grams of lupin protein for five weeks reduces glucose-dependent insulinotropic polypeptide (GIP) by approximately 20% and ghrelin by 16% in adolescent boys with overweight or obesity.

In plain English

In adolescent boys with overweight or obesity, consuming 10 grams of lupin protein daily for five weeks lowers GIP levels by about 20% and ghrelin levels by 16%.

See the scientific wording

Daily consumption of 10 grams of lupin protein for five weeks significantly reduces glucose-dependent insulinotropic polypeptide (GIP) by approximately 20% and ghrelin by 16% in adolescent boys with overweight or obesity, suggesting a potential role in appetite regulation and postprandial glucose control.

Why this might work

Lupin protein feeds beneficial gut bacteria that make butyrate, which tightens the gut lining and stops inflammatory molecules from entering the blood. This reduces inflammation in fat tissue, lowers levels of hunger hormones ghrelin and GIP, and decreases the need for insulin, leading to better blood sugar control.

  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 it lowered two hunger-related hormones—GIP and ghrelin—by exactly the amounts the claim says. So yes, it supports the idea that this drink helps reduce hunger and improve blood sugar response.
