Intermittent fasting is all over my feed, and I tried 16:8 for two months. I lost weight, but my energy crashed during morning workouts. Is it really better than just eating three balanced meals? Some studies show it improves insulin sensitivity, but they're short-term and often on mice. I know a dietitian who says it's just a tool to cut calories, not magic. But if it helps people stick to a schedule, maybe that's enough.
