Timing your meals may stop weight regain, new study hopes
NCT ID NCT07190170
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether time-restricted eating (eating only during a set window each day) can help adults who have recently lost weight keep it off and avoid regaining fat. About 110 adults aged 25-65 who lost at least 5% of their body weight in the last 3 months will be randomly assigned to either follow time-restricted eating or continue their usual eating pattern for 12 months. The goal is to see if this approach reduces weight and fat regain.
