5 common fasting mistakes
Fasting is simple, but a handful of avoidable errors make it feel much harder than it is. Fix these and it usually clicks.
1. Breaking the fast with a feast
A huge, sugary, or greasy first meal spikes blood sugar and overwhelms a quiet gut, leaving you bloated and foggy. Ease in with water, a little protein, then your real meal 15–20 minutes later.
2. Ignoring electrolytes
Most fasting headaches and low-energy slumps are low sodium, not low food. A pinch of salt or a sugar-free electrolyte drink fixes the majority of early discomfort.
3. Under-eating protein
A short eating window makes it easy to fall short on protein — which is exactly what protects muscle while you fast. Anchor every meal with a real protein source.
4. Going too hard, too fast
Jumping straight to 20:4 or OMAD before 16:8 feels easy is the fastest way to quit. Step up one rung at a time, and only once the current window feels automatic.
5. Never adapting to your day
Fasting the same way on a hard-training, poor-sleep day as on a rested one backfires. Shorten the fast when recovery is low; extend a little when you feel strong. Rigidity is what breaks streaks.
