The Claim

In postmenopausal women, a 12-week low-fat vegan diet supplemented with soybeans causes a mean weight loss of 3.6 kg and a 92% reduction in severe hot flashes compared to a control group maintaining their usual diet.

Cause and effect

In plain English

Postmenopausal women who followed a low-fat vegan diet with soybeans for 12 weeks lost an average of 3.6 kg and experienced a 92% reduction in severe hot flashes, while women who kept their normal diet showed no significant change.

See the scientific wording

In postmenopausal women, adopting a low-fat vegan diet supplemented with soybeans for 12 weeks causes a mean weight loss of 3.6 kg and reduces severe hot flashes by 92%, compared to no significant change in a control group maintaining their usual diet, indicating that this dietary pattern is an effective non-hormonal intervention for managing menopausal symptoms and body weight.

Why this might work

When people stop eating animal foods and eat more soy and plants, they take in fewer harmful compounds that interfere with how the body uses insulin and signals fat cells. This lets insulin work better, changes the hormones made by fat tissue, and tells the brain’s temperature control center to stop overreacting, which stops hot flashes. At the same time, the body starts burning stored fat because it can use energy more efficiently.

  1. Study: Processed foods in the context of a vegan diet, and changes in body weight and severe hot flashes in postmenopausal women: a secondary analysis of a randomized clinical trial

    Women who ate only plant-based foods with soybeans for 12 weeks lost about 8 pounds and had far fewer intense hot flashes, while women who kept eating normally didn’t change. This shows the diet really helped.
