Eating earlier doesn’t make people move more or less during the day—activity levels stay the same.

Scientific Claim

Early time-restricted feeding does not significantly alter spontaneous physical activity energy expenditure in overweight adults, with a mean difference of 11 ± 9 kcal/day (p=0.23) under controlled conditions.

Original Statement

“Spontaneous physical activity (SPA) was unaffected (180±82 vs. 168±90 kcal/day; Δ=11±9 kcal/day; p=0.23).”
