Frequently Asked Questions
What is macro cycling and how does it work?
Macro cycling is a nutrition strategy where you vary your carbohydrate and fat intake across different days while keeping protein constant. High-carb days fuel intense training sessions; low-carb days promote fat burning on rest or light-activity days. Total weekly calories stay consistent with your goal.
How is macro cycling different from carb cycling?
Carb cycling varies only carbohydrate intake. Macro cycling goes further: when carbs go down, fat goes up proportionally, so total daily calories remain stable. Protein stays fixed throughout. This makes macro cycling more flexible and easier to plan than strict carb cycling.
Is macro cycling effective for weight loss?
Macro cycling can support fat loss by maintaining a weekly calorie deficit while matching fuel to activity. High-carb days preserve performance and lean muscle; low-carb days encourage fat oxidation. Evidence on macro cycling specifically is limited, but the underlying principles — calorie control and nutrient timing — are well-supported.
What should I eat on high-carb days in a macro cycling plan?
On high-carb days, prioritize complex carbohydrates like oats, brown rice, sweet potatoes, whole-grain pasta, and fruit. Keep fat moderate and protein high. Avoid high-fat processed foods that combine dense fat with high carbs in the same meal.
How do I calculate my macros for a cycling plan?
Start with your TDEE (Total Daily Energy Expenditure). Set protein at 1.6–2g per kg of body weight every day. On high-carb days, allocate 45–50% of calories to carbs and 20–25% to fat. On low-carb days, flip those percentages — 20–25% carbs and 40–45% fat. Moderate days sit between the two extremes.
