Study: Fasting 12–16 Hours Daily Best for Longevity

A review of 31 human studies suggests a 12 to 16-hour daily fasting window is the sweet spot for health benefits like weight loss and blood sugar control. Longer fasts didn't show significantly increased benefits for metabolism or longevity, potentially due to compliance issues. This means most people can skip an early meal or late snack rather than endure longer periods without food.
