Energy balance

Intermittent fasting (16:8 time-restricted eating) produces significantly greater weight loss and improvements in fasting glucose and triglycerides compared to standard calorie restriction in obese adults over an 8-week period.

If you are obese and struggling with weight loss, try a 16:8 intermittent fasting schedule (eat within an 8-hour window, fast for 16) for at least 8 weeks. This approach may yield better weight loss and metabolic improvements than simply counting calories, and it is generally well-tolerated.

GoodSupportsHIGH confidence
The IF group achieved greater weight loss (−4.1 ± 2.1 kg) compared to the SCR group (−2.7 ± 1.9 kg), with statistically significant differences (p=0.012)... Improvements in fasting glucose (−7.2 ± 9.1 mg/dL vs. −3.1 ± 8.7 mg/dL; p=0.041) and triglyceride levels (p=0.048) were observed with IF
