“We expected significant differences in weight regain across the three exercise groups, with the highest, intermediate and least regain in the 150, 225 and 300 (minutes per week) respectively,” the research team said in the Obesity journal.
The results didn’t match their expectations. There was little difference in the amount of weight regained across all three groups, regardless of how much time they spent exercising.
“The average weight regain across the three randomized groups was minimal, ranging from 1.1 to 3.2 kg with considerable inter-individual variation,” said the researchers.
That wasn’t the only interesting finding. Turns out that even with frequent check-ins with health and fitness professionals, adherence to all three exercise regimes was poor. Only 11 of the 76 individuals in the 150-minute group, two of the 80 in the 225-minute cohort and one of the 79 tasked with 300 minutes a week met their exercise goals. The average amount of weekly exercise in the groups was 129, 153 and 179 minutes respectively.
