The Claim

Increased intake of daidzein, genistein, and glycitein from soy is associated with weight loss in postmenopausal women, with each isoflavone showing a strong negative correlation with body weight change (r = -0.67 for daidzein and genistein; r = -0.66 for glycitein).

In plain English

Higher consumption of daidzein, genistein, and glycitein from soy is linked to a decrease in body weight among postmenopausal women.

See the scientific wording

Increased intake of daidzein, genistein, and glycitein from soy is associated with weight loss in postmenopausal women, with each isoflavone showing a strong negative correlation with body weight change (r = -0.67 for daidzein and genistein; r = -0.66 for glycitein).

Why this might work

When women consume more soy isoflavones, these compounds bind to specific receptors in the brain that control body temperature, which reduces the body's tendency to burn extra energy to cool down. This allows the body to store more fat instead of using it for heat, leading to weight loss over time.

    The study found that when postmenopausal women ate more soy compounds (daidzein, genistein, glycitein), they tended to lose more weight — and the link was strong, just like the claim said.
