The Claim
Daily consumption of 10 grams of soy or lupin protein for five weeks results in a 15-19% reduction in HOMA2-IR in adolescent boys with overweight or obesity, independent of changes in body weight or BMI.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adolescent boys with overweight or obesity, consuming 10 grams of soy or lupin protein daily for five weeks leads to a 15-19% decrease in HOMA2-IR, a measure of insulin resistance, without changes in body weight or BMI.
See the scientific wording
Daily consumption of 10 grams of soy or lupin protein for five weeks significantly improves insulin sensitivity in adolescent boys with overweight or obesity, as measured by a 15-19% reduction in HOMA2-IR, independent of changes in body weight or BMI, suggesting these plant proteins may help mitigate early metabolic dysfunction.
When adolescent boys consume soy or lupin protein, gut bacteria break down the protein and fiber to produce butyrate, a molecule that tightens the gut lining. This prevents harmful bacterial toxins from entering the bloodstream, which lowers inflammation in fat tissue. With less inflammation, the body’s cells respond better to insulin, so blood sugar drops without needing more insulin.
What the research says
1 studyKids who drank a daily shake with soy or lupin protein for five weeks became better at using insulin to control blood sugar — even though they didn’t lose weight. This could help lower their risk of getting type 2 diabetes later.
