What is Carb Cycling?

Strategic manipulation of daily carbohydrate intake aligned with training demands and body composition goals. High-carb days fuel intense training and replenish glycogen, while low-carb days enhance fat oxidation and insulin sensitivity.

Is there evidence for it?

EVIDENCEmoderate

How do you do Carb Cycling?

  1. 1.Establish baseline macros: set protein at 1g/lb bodyweight and fats at 0.3-0.4g/lb. Carbs become the variable. Calculate high-carb (2-3g/lb), moderate-carb (1-1.5g/lb), and low-carb (0.5g/lb or less) day targets.
  2. 2.Assign high-carb days to your hardest training days (heavy leg days, intense HIIT, competition days). Assign moderate-carb to moderate training days and low-carb to rest or light activity days.
  3. 3.On high-carb days, time the majority of carbs around training: 30-50% pre/intra/post workout. Prioritize complex carbs (rice, oats, potatoes, fruit).
  4. 4.On low-carb days, increase healthy fat intake to compensate for reduced calories. Focus on non-starchy vegetables, proteins, nuts, avocado, and olive oil.
  5. 5.Run a typical weekly pattern: 2-3 high days, 2 moderate days, 2-3 low days. Adjust based on weekly weight trends and training performance over 4-6 week blocks.

How long does it take?

Ongoing daily tracking, 4-6 week assessment cycles.

Is it hard to start?

hard.
