VIDEO LESSON
The evidence
In a 12-month randomized trial, time-restricted eating plus calorie restriction produced similar weight loss to calorie restriction alone. Benefits seem to come mostly from eating less.
Who it may suit
• People who find a clear eating window easier than counting
• Those who snack late at night
Cautions
• Not advised with a history of disordered eating
• Use caution with insulin or sulfonylureas because of low blood sugar risk
• Protect protein intake within the window
