Energy balance

A small change approach (SCA) consisting of a 2000-step daily increase and 100 kcal daily reduction does not prevent long-term weight gain in adults with overweight or obesity compared to monitoring alone over 2-3 years.

If you have overweight or obesity, simply adding 2000 steps and cutting 100 calories a day is unlikely to keep your weight off in the long run (2+ years). While you might see some benefit for the first year, it eventually fades to being no better than just having your weight checked regularly. For long-term management, you likely need more than just these small, isolated changes.

Why this rating

Randomized controlled trial with 320 participants, though it was stopped early due to funding cuts, reducing power slightly.
