Frequently Asked Questions
Why do I crash after eating sugar?
Simple sugars cause rapid blood glucose spikes that trigger insulin release. The insulin drives glucose into cells quickly, often causing blood sugar to drop below baseline, producing fatigue, irritability, and hunger. Complex carbs with fiber prevent this spike-crash cycle.
Is caffeine a good source of energy?
Caffeine does not provide energy; it blocks adenosine receptors that signal tiredness. This creates the sensation of alertness without actual fuel. Caffeine works best combined with food-based energy, not as a replacement for proper nutrition.
How long before exercise should I eat?
Full meals need 2-3 hours to digest before intense exercise. Smaller carb-based snacks can be eaten 30-60 minutes before. Individual tolerance varies, so experiment during training, not competition or important workouts.
Can I get energy from fat instead of carbs?
Yes, especially during low-intensity activity. Fat adaptation through low-carb eating can train your body to use fat efficiently. However, high-intensity exercise still relies primarily on carbohydrates regardless of dietary adaptation.
