What was done
This review summarized emerging human research evaluating time-restricted eating (TRE), defined as confining daily caloric intake to a 4-to-10-hour window with zero-calorie beverages during fasting hours, on body weight and cardiometabolic risk factors.
What was found
The review reported that TRE spontaneously decreased energy intake by 20-30% under ad libitum conditions, resulting in a statistically significant weight loss of 1-4%. TRE also decreased systolic and diastolic blood pressure independent of weight loss, with improvements observed in fasting insulin and insulin resistance.
Why it matters
This paper consolidates preliminary clinical evidence showing that limiting the daily eating window can produce modest weight loss and improve metabolic health markers without formal calorie counting.
Limits
The paper is a narrative review with no search strategy, meta-analysis, or quality appraisal described in the abstract. The number of included trials, sample sizes, study durations, and exact numerical effects for blood pressure and insulin parameters are not reported. The authors note the data are preliminary.
