Energy balance
Preventing weight gain requires only small, sustainable changes in energy balance (approximately 100 kcal/day), whereas treating established obesity requires large, difficult-to-sustain behavior changes that trigger strong physiological compensation.
To stop gaining weight, you don't need a drastic diet or intense gym sessions. Aim for a modest daily deficit of about 100 calories. This can be achieved by walking 2,000 extra steps a day and eating 100 calories less. These small, sustainable changes are easier to maintain than strict diets and are effective for preventing weight gain in the vast majority of adults.
it has been estimated that relatively small changes in energy intake and expenditure totaling 100 kcal per day could arrest weight gain in most people... Prevention of weight gain can be accomplished by smaller behaviour changes. in addition to being easier to sustain than larger behaviour changes, smaller ones produce less compensation by the energy balance regulatory system.
Why this rating
The paper is a review article citing multiple large-scale longitudinal cohort studies (CARDIA, NHANES, EPIC-PANACEA) and mathematical modeling, though it lacks a single primary randomized controlled trial testing the specific 'small changes' protocol against a control in a long-term setting.
