A follow-up of 99 adults with overweight or obesity found that weight differences remained one year after a 12-week time-restricted eating program, a promising result that is also smaller and less controlled than the phrase "fasting worked for a year" suggests. [1]

ScienceDaily, reporting edited material from the University of Granada rather than the primary paper itself, said all participants received Mediterranean-diet education and entered four groups: a usual eating window of at least 12 hours, an early eight-hour window, a late eight-hour window and a self-selected eight-hour window. [1]

At the one-year assessment, the early and late groups had maintained more weight loss than the control group and the early group also preserved a larger reduction in fat mass, follow-up differences rather than proof that one clock suits every patient or timing alone produced the result. [1]

The crucial boundary arrived when the structured intervention ended and about one-third of participants chose to continue intermittent fasting during the following year, a choice that may show some people found the practice manageable but also means later exposure was partly self-selected rather than fully governed by the original assignment. [1]

The release does not supply the follow-up count for each group, post-program calorie intake, activity, adherence or harms, missing denominators that matter in a 99-person study where attrition or changed behavior can move the result, so the study offers a durability signal worth testing without turning an eight-hour eating window into a universal prescription.
