The Claim

Among obese adults, a 12-month time-restricted eating regimen with an 8 a.m. to 4 p.m. eating window results in an average weight loss of 8.0 kg, which is not significantly different from the 6.3 kg average weight loss observed with daily calorie restriction without time limits, indicating that restricting eating hours does not enhance weight loss beyond the effects of calorie reduction alone.

Cause and effect
1 study reviewed
In plain English

If you're overweight and eat only between 8 a.m. and 4 p.m. for a year, you’ll lose about 8 kg — but if you just eat fewer calories without worrying about when you eat, you’ll lose about 6.3 kg. The difference is so small that it doesn’t really matter which method you pick — cutting calories is what matters most.

What the research says

  1. Study: Calorie Restriction with or without Time-Restricted Eating in Weight Loss.

    The study found that eating only between 8 a.m. and 4 p.m. didn’t help people lose more weight than just eating fewer calories, no matter when they ate. So, timing meals doesn’t give you extra weight loss power beyond cutting calories.
