Intermittent fasting for 16 hours daily provides general health benefits
Clinical evidence and systematic reviews generally support that a 16-hour daily intermittent fasting routine can provide general health benefits, particularly regarding weight management and metabolic parameters.
The retrieved papers consistently indicate that intermittent fasting and time-restricted eating protocols (such as 16:8) are effective for weight management, body composition improvements, and cardiometabolic health markers. While some studies suggest benefits are largely driven by spontaneous caloric restriction or depend on age and protocol specifics, the overall body of evidence supports the claim of general health benefits.

Paper 0 demonstrates that an intermittent fasting regimen improves metabolic syndrome biomarkers and aids in weight management comparably to continuous energy restriction.
