I’m listening to the Dr sims episode right now. I always work out fasted because I do so right when I wake up (generally). What is sufficient to eat before I start my workout? A protein shake? A yogurt?

If you prefer to work out fasted, Andrew Huberman suggests several approaches:

1. Simple Hydration: Just water with caffeine, electrolytes, or both before the workout.
2. Evening Preparation: Consume carbohydrates the night before. This helps ensure your glycogen stores are topped off for the next morning's workout 1 2.
3. Small Pre-Workout Meal: If you feel hungry, Huberman suggests a small meal that includes protein and fat, like a protein shake or some fat-based food like nuts, to avoid major shifts in blood sugar levels 3 2.

Incorporating these strategies helps manage energy levels and optimizes performance while working out. If you find that you need a small boost, a protein shake or yogurt could be just enough without feeling too full.
