Time restricted eating for weight loss is one of the most searched diet approaches worldwide. A new pooled analysis of five clinical trials suggests that an 8 hour eating window may lead to slightly greater weight loss than longer eating windows, especially compared with a 12 hour schedule. The findings are promising, but they do not mean that every patient should follow strict 16:8 fasting. Ayurveda also emphasizes meal timing, digestion, metabolic rhythm and individual body strength, making personalized guidance important before starting fasting for weight loss.
