The Claim
Weight loss from a low-fat vegan diet supplemented with soybeans is not significantly associated with reduction in severe hot flashes in postmenopausal women (r = +0.20, p = 0.12), indicating that these two outcomes are driven by separate mechanisms.
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 postmenopausal women, losing weight on a low-fat vegan diet with soybeans does not correlate with a decrease in severe hot flashes, suggesting the two changes occur independently.
See the scientific wording
Weight loss from a low-fat vegan diet supplemented with soybeans is not significantly associated with reduction in severe hot flashes in postmenopausal women (r = +0.20, p = 0.12), suggesting the two outcomes are driven by separate mechanisms.
A compound from soy called daidzein enters the bloodstream and binds to a specific receptor in the brain that controls body temperature. This binding reduces overactivity in the nerves that trigger sudden heat release, preventing the intense flushing known as hot flashes. Weight loss does not cause this effect — it happens independently through this direct brain pathway.
What the research says
1 studyThe study found that when women lost weight on a vegan diet with soy, their hot flashes got better—but not because of the weight loss. Instead, the soy itself (specifically a compound called daidzein) was what helped reduce hot flashes, meaning weight loss and hot flash relief happened for different reasons.
