Frequently Asked Questions

What is carb cycling?

Carb cycling is a strategic dietary method that alternates high, medium, and low carbohydrate days throughout the week to support fat loss, muscle gain, and performance.

Is carb cycling effective for weight loss?

Yes, it can be effective by manipulating insulin response and optimizing energy use, especially when paired with training schedules.

Do I need to exercise on high-carb days?

High-carb days are ideal for heavy training or intense workouts. Low-carb days are better suited for rest or light activity.

How many high-carb days should I have per week?

It depends on your goals and training frequency. Most people use 1–2 high-carb days, 2–3 medium, and 2 low-carb days weekly.

Can I use this calculator for bulking?

Yes. Adjust your TDEE upward and set higher calorie targets for high- and medium-carb days while maintaining protein.

What's the difference between the three carb cycling methods?

The 3-day cycle rotates through high, moderate, and low carb days continuously. The weekly schedule allows for customizing specific days of the week. The training-based approach increases carbs on workout days and reduces them on rest days.

How much protein should I eat when carb cycling?

Protein intake remains consistent throughout carb cycling to support muscle maintenance and recovery. This calculator recommends between 1.2-1.8g of protein per kg of bodyweight based on your activity level.
