What this tool does

Estimates a realistic daily carbohydrate target and timing hints (before, during, and after training) based on your body weight and session demands.

Who and when to use it

• Endurance athletes planning fueling for longer sessions.
• Strength trainees trying to keep training output stable while managing body composition.
• Anyone who feels under-fueled but wants a structured carb baseline.

Step-by-step usage

1. Enter your body weight and session duration.
2. Select endurance or strength based on your primary workout type.
3. Choose intensity as honestly as possible.
4. Apply the suggested g/day and pre/during/post distribution for 7–14 days, then adjust by performance and recovery.

Example interpretation

If your output is 320 g/day and your long run day includes a during-session target, keep carbs higher that day and lower on light or rest days while keeping protein stable.

FAQ

Do I need to hit the exact number every day?

No. Use the range as a guide and periodize carbs by training load.

Is this only for athletes?

No. Recreational trainees can use it to prevent low-energy sessions.

Should carbs drop on rest days?

Usually yes, but avoid very low intakes if recovery or sleep worsens.

Do I still need protein planning?

Yes. Carbs and protein should work together for adaptation and recovery.
