Carb Cycling places carbohydrate load around demands while preserving weekly energy alignment.
01Decision tree for day selection
Use the same template each week and adapt only from objective signs.
| Signal | Decision | Carb direction |
|---|---|---|
| Hard session in next 24 hours | preserve session quality | higher |
| Light day or low readiness | reduce non-essential glycogen load | moderate |
| Recovery stress, poor sleep | avoid aggressive load | lower |
| Adherence drift | protect plan realism first | simplify, then scale up |
02Weekly patterns
3:4 high-low structure
| Day block | Target profile |
|---|---|
| 3 training days | higher carb |
| 4 low activity days | moderate to low carb |
Use nutrient timing for pre-post session fuel and keep protein stable.
4:3 performance structure
| Day block | Target profile |
|---|---|
| 4 hard days | higher carb with stronger post session support |
| 3 recovery days | controlled carb with extra micronutrients |
Use this when recovery markers stay solid and training volume is high.
5:2 threshold structure
| Day block | Target profile |
|---|---|
| 5 normal training days | mixed carb profile |
| 2 rest or low-load days | lower carb with moderate fat |
Use this for maintenance-like blocks where adherence stress is low.
03Failure patterns before drift
| Pattern | Why it happens | Fix |
|---|---|---|
| Frequent crash on low-carb days | underestimating training carryover | add 15 to 25 g around sessions |
| Rebound spikes on rest days | uncontrolled high-speed snacks | pre-portion post-dinner carbs |
| Schedule bypass on social days | rigid plan and poor preparation | add a flexible carb bracket for events |
| Logging gaps with no adjustment | hidden mismatch between plan and execution | reduce block complexity for 7 days |
Carb cycling works best when decisions come from training stress, recovery, and adherence logs rather than trend-chasing. For race-week or event-specific high-carbohydrate work, use glycogen loading. For meal build support, pair with macro ratios and macro-friendly recipes.
