To the Editor: In their randomized controlled trial, Dr Morey and colleagues1 reported that among older, long-term (≥5 years) survivors of colorectal, breast, and prostate cancer, a diet and exercise intervention reduced the rate of self-reported functional decline. The body mass index (BMI) of the participants ranged from 25 to 40 (calculated as weight in kilograms divided by height in meters squared).
