Dieting vs Exercise
Author: Oksana Aron, MD Source: Weight Loss NYC Oct 14, 2025Food vs Fitness
Some interesting medical studies compared very low calorie dieting alongside different types of fitness. The goal was to assess weight loss and bone loss in older adults. Participants were randomly split into four groups: dieting, dieting plus fitness, fitness without dieting, and neither/none
. A follow up study broke the fitness groups down further into three groups of aerobic, strength training, and both
(and none, for control).
Both studies showed all the dieting groups lost weight, whereas the fitness without dieting groups did not, however bone density measurements declined most in the non-fitness diet group.
All three of the groups who dieted and exercised lost about 9 percent of their starting weight, … But aerobic exercise didn’t prevent weight-loss-induced bone loss, whereas strength training alone or combined with aerobic exercise was equally effective at diminishing bone loss [and] for lessening muscle loss.
