Workout Meal Timing Calculator
Enter your workout start time and get suggested clock times for a pre-workout meal, a pre-workout snack and post-workout refueling.
How it works
main meal ≈ 3 h before · light snack ≈ 45 min before · post-workout refuel within ~1–2 h of finishing
Meal timing tunes energy and recovery around training. A larger mixed meal 2–3 hours before gives time to digest so you are not training on a full stomach, while a small, easily digested carb snack 30–60 minutes before tops up fuel for early sessions. Afterwards, protein plus carbohydrate within a couple of hours supports muscle repair and glycogen refill; the old "30-minute anabolic window" is now seen as more forgiving than once believed, so total daily intake still matters most.
Worked example
For a 5:30 PM workout, the tool suggests a main meal around 2:30 PM (three hours before), an optional light snack by about 4:45 PM, and refueling by roughly 6:30 PM after you finish.
Frequently asked questions
Do I have to eat right after training?
The recovery window is wider than the old 30-minute rule suggested. Eating within a couple of hours is fine for most people, and if you ate beforehand the urgency is lower still. Consistent daily protein and carbs matter more.
Should I train fasted?
Some people tolerate light morning cardio fasted, but for longer or intense sessions a small carb snack beforehand usually improves performance. It comes down to goals and how you feel.
What should the pre-workout meal contain?
Mostly carbohydrate for fuel, moderate protein, and lower fat and fiber close to training to avoid stomach discomfort. The nearer to the session, the smaller and simpler it should be.
