The Claim

In postmenopausal women with hormone receptor-positive breast cancer on adjuvant endocrine therapy, a personalized plant-based diet combined with supervised exercise therapy results in a significantly greater increase in lean mass after 24 weeks compared to a minimal attention control group.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect
1 study reviewed
In plain English

Postmenopausal women with hormone receptor-positive breast cancer who followed a personalized plant-based diet and supervised exercise for 24 weeks gained more lean mass than those who received minimal attention.

See the scientific wording

In postmenopausal women with hormone receptor-positive breast cancer on adjuvant endocrine therapy, a personalized plant-based diet combined with supervised exercise therapy led to a significantly greater increase in lean mass compared to a minimal attention control group, with a statistically significant difference (P<0.001) observed after 24 weeks.

Why this might work

Eating more plants and exercising regularly lowers inflammation in the body and turns on signals that tell muscles to grow and stop breaking down, leading to more muscle mass over time.

  1. Study: Effects of plant-based diet (PBD) and exercise therapy (Ex) on weight and body composition in patients with primary hormone receptor (HR) positive breast cancer: A phase 2 randomized controlled trial.

    Women with breast cancer who ate a plant-based diet and walked regularly lost more fat and actually gained muscle, while those who just got a treadmill and monthly calls didn’t. The study proves the combo worked better.
