The Claim

Daily consumption of soy or lupin protein for five weeks reduces serum levels of plasminogen activator inhibitor-1 (PAI-1) and visfatin by approximately 10–14% in adolescent boys with overweight or obesity.

Cause and effect
1 study reviewed
In plain English

In adolescent boys with overweight or obesity, eating soy or lupin protein every day for five weeks lowers blood levels of PAI-1 and visfatin by 10–14%.

See the scientific wording

Daily consumption of soy or lupin protein for five weeks reduces serum levels of plasminogen activator inhibitor-1 (PAI-1) and visfatin by approximately 10–14% in adolescent boys with overweight or obesity, indicating a reduction in adipose tissue-related inflammation.

Why this might work

Eating soy or lupin protein changes the good bacteria in the gut to produce more butyrate and reduce harmful bacteria. This strengthens the gut lining, so fewer toxins enter the bloodstream. Fewer toxins mean less activation of inflammation in fat tissue, which lowers the release of inflammatory proteins into the blood.

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

    This study gave overweight teen boys soy or lupin protein drinks every day for five weeks and found that two inflammation markers in their blood went down, just like the claim said. So yes, the drinks helped reduce inflammation linked to fat tissue.
