Energy balance
Combining time-restricted eating (TRE) with calorie restriction (CR) significantly reduces body weight, fat mass, and waist circumference compared to calorie restriction alone in overweight or obese adults.
If you are overweight or obese, combining a moderate calorie deficit with time-restricted eating (eating within a specific window of the day) will help you lose more weight and fat than just counting calories alone. However, do not expect this combination to significantly improve your blood pressure, blood sugar, or cholesterol levels beyond what you would get from calorie restriction alone.
The pooled results showed that TRE with CR reduced the body weight, fat mass, and waist circumference significantly (WMD: −1.40, 95% CI: −1.81 to −1.00... WMD: −0.73... WMD: −1.87...)
Why this rating
Based on 8 RCTs with 579 participants; GRADE assessment rated weight loss as 'low quality' due to risk of bias and consistency issues in some studies.
