The Claim

Daily intake of 10 grams of soy protein for five weeks reduces total cholesterol by 10.4% and triglycerides by 17.1% in adolescent boys with overweight or obesity, and this effect is not observed with lupin protein.

Cause and effect
1 study reviewed
In plain English

In adolescent boys with overweight or obesity, consuming 10 grams of soy protein daily for five weeks lowers total cholesterol by 10.4% and triglycerides by 17.1%, while lupin protein does not produce these changes.

See the scientific wording

Daily intake of 10 grams of soy protein for five weeks significantly reduces total cholesterol by 10.4% and triglycerides by 17.1% in adolescent boys with overweight or obesity, indicating a favorable impact on lipid metabolism that is not observed with lupin protein.

Why this might work

Soy protein feeds beneficial gut bacteria that make butyrate, which tightens the gut lining and stops harmful bacterial toxins from entering the blood. This lowers inflammation in the liver and fat tissue, which stops the liver from making too much cholesterol and triglycerides.

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

    In a study with overweight teen boys, drinking a soy protein shake every day for five weeks lowered their bad blood fats (cholesterol and triglycerides), but a lupin protein shake didn’t — it just helped control hunger instead. So yes, soy worked for fats, lupin didn’t.
