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 resulted in a mean weekly energy deficit compliance of 95% in the first month and 64% by the sixth month.

In plain English

Among postmenopausal women with hormone receptor-positive breast cancer taking hormone therapy, a personalized plant-based diet and supervised exercise led to 95% adherence to a weekly energy deficit in the first month and 64% adherence by the sixth month.

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 achieved a mean weekly energy deficit compliance of 95% in the first month and 64% by the sixth month, indicating high initial adherence that declined over time.

Why this might work

When a person eats less and moves more, the body slows down its energy use and increases hunger signals, making it harder to keep up with the diet and exercise plan over time. The initial strict routine feels easier because motivation is high, but as the body adjusts and daily life gets in the way, sticking to the plan becomes harder.

  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.

    The study found that women following a plant-based diet and walking program stuck to it 95% of the time in the first month, but only 64% of the time by six months — exactly what the claim says.
