The Claim

Among obese adults, consistent adherence to an 8-hour early time-restricted eating window (07:00–15:00) for 14 weeks results in a 3.7 kg greater reduction in body weight and a 2.8 kg greater reduction in body fat compared to adherence to a ≥12-hour eating window.

In plain English

Obese adults who ate only between 7 a.m. and 3 p.m. for 14 weeks lost 3.7 kg more body weight and 2.8 kg more body fat than those who ate over a 12-hour or longer window.

See the scientific wording

Among obese adults who consistently adhered to an early time-restricted eating schedule (8-hour window from 07:00 to 15:00) for 14 weeks, body weight decreased by 3.7 kg and body fat decreased by 2.8 kg more than in those following a ≥12-hour eating window, suggesting that strict adherence to early time-restricted eating may enhance fat loss and weight reduction in this population.

Why this might work

When eating is limited to the morning hours, the body switches to burning fat for energy during the long fasting period that follows, because the internal clock tells cells to use stored fat instead of glucose when no food is coming.

  1. Study: Early Time-Restricted Eating Affects Weight, Metabolic Health, Mood, and Sleep in Adherent Completers: A Secondary Analysis

    People who ate only between 7 a.m. and 3 p.m. for 14 weeks lost nearly 4 pounds more weight and almost 3 pounds more fat than those who ate over a longer day—even when they ate the same amount—because their eating schedule helped their bodies burn fat better.
