Energy balance

High-frequency aerobic exercise (up to 180 min/week) during maintenance does not significantly improve long-term weight loss compared to lower exercise levels, likely due to adherence difficulties.

Do not aim for extreme exercise volumes (like 3 hours a week) if you struggle to maintain them. High exercise doses are hard to sustain long-term and may lead to feelings of failure. Focus on moderate, consistent activity that you can maintain year-round, rather than high-intensity regimens that you might quit.

However, the higher amounts of self-reported aerobic exercise were not accompanied by significantly greater mean weight losses, and the higher exercise levels were not maintained at the 12- and 18-month follow-ups.

Why this rating

RCT data, but self-reported exercise adherence is the metric.
