The Claim
A high-fiber, low-fat dietary intervention in women with a history of breast cancer does not result in significant weight loss over one year, and the observed hormonal changes are not secondary to changes in body weight.
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 women with a history of breast cancer, a high-fiber, low-fat diet for one year does not cause significant weight loss, and any hormonal changes observed are not caused by changes in body weight.
See the scientific wording
A high-fiber, low-fat dietary intervention in women with a history of breast cancer does not result in significant weight loss over one year, indicating that observed hormonal changes are not secondary to changes in body weight.
Eating more fiber causes estrogen to stick to waste in the gut, so less of it gets reabsorbed into the blood. This lowers the amount of active estrogen circulating in the body, even when body weight stays the same.
What the research says
1 studyThis study found that women who ate more fiber and less fat had lower estrogen levels—even though they didn’t lose any weight. So, the drop in estrogen wasn’t because they lost weight; it was because of the diet itself.
