Choose Eating Before Training when…
You're doing sessions over 60 minutes, training at high intensity, doing strength training (pre-workout protein matters), or want optimal performance during the session.
Choose Fasted Training when…
You prefer training in the morning before eating, have sensitive digestion that causes GI issues with food before training, are doing low-intensity cardio under 60 minutes, or follow an intermittent fasting protocol.

FAQ
What's the best pre-workout food?
For sessions over 60 minutes: 40-60g carbohydrate + 20-30g protein, 1-2 hours before training. Oats with protein powder, chicken and rice, or Greek yoghurt with fruit are practical options. Avoid high-fat, high-fibre meals that slow digestion before training.
How long before a workout should I eat?
The general guideline: a full meal 2–3 hours before exercise; a small snack (simple carbs, minimal fat and fibre) 30–60 minutes before. The 2–3 hour window allows significant digestion and avoids the gastrointestinal discomfort that can occur when exercising with a full stomach. Individual tolerance varies — some athletes train comfortably 60–90 minutes after a full meal; others need the full 3 hours. High-fat and high-fibre meals delay gastric emptying and require longer pre-exercise gaps.
What should I eat before a morning workout if I train early?
For early morning training (5–7am), a small, easily digestible carbohydrate snack 30 minutes before is practical: a banana, a rice cake with honey, or sports drink. If the session is under 60 minutes at moderate intensity, training fasted is also effective and avoids the logistical challenge of eating very early. For longer or high-intensity sessions, even a small amount of carbohydrate before training is associated with better performance than fasted training.
