Adherence
Initiating supervised exercise immediately at the start of a weight loss program (0-3 months) yields significantly greater weight loss and waist circumference reduction compared to delaying exercise until 6-9 months, with benefits persisting at 24 months.
If you are starting a weight loss journey, begin supervised exercise immediately, not after you have lost some weight. This study shows that starting circuit training (light weights, high heart rate) within the first 3 months leads to significantly more weight loss and waist reduction than starting it later. The early exercise acts as a motivator to keep you on track.
The most effective weight loss regimen is a combination of intensified behavioural modification and weight training introduced from the very beginning of the weight loss period.
Why this rating
Randomized controlled trial with 24-month follow-up, though dropout rates were significant (35%).
