Before you fill out the carb cycling calculator, it’s a good idea to skim through the information below. That way, you will understand carb cycling and how it works.
What is Carb Cycling?
Carb cycling refers to alternating your daily carbohydrate intake. Usually, a “cycle” includes low, medium, and high-carb days over the course of the week. And the exact cycle depends on your body, activity level, and goals.
But why use carb cycling in the first place? After all, it sounds a lot more complicated than just eating low carbs all the time.

Why Use Carb Cycling?
Low-carb diets are arguably the most popular for weight loss. But, the reason they work is not simply the elimination of carbs.
Instead, reducing carbs gets results because it lowers your blood sugar. This, in turn, lowers insulin and promotes fat burning.

Figure 1. Low-carb diets lower blood sugar and insulin. Carb cycling does the same thing without being overly restrictive.
However, restricting carbs all the time isn’t necessarily the best approach in the long run, especially in extreme cases like the keto diet.
For one, it’s not practical for most people because eliminating carbs doesn’t fit well with our family or social lives.
In addition, low-carb diets often result in prolonged calorie restriction. This energy deficit helps with short-term weight loss but can lead to metabolic damage and hormone imbalance.
On the other hand, carb cycling allows the flexibility to enjoy carbs with your family and friends. So you can live your life in a more normal fashion.
When used correctly, high-carb days help boost your metabolism and prevent the unwanted side effects of restrictive dieting.

Generally, carb cycling coincides with your workout schedule. Low carbs when you don’t work out, medium carbs when you do. And a weekly high carb day to boost your metabolism.
Again, the number of low, medium, and high days varies with your situation. For example, your numbers depend on your body, schedule, and fitness goals. That’s where the carb cycling calculator comes in.
How the Carb Cycling Calculator Works
The carb cycling calculator works by asking you questions about your unique situation. First, specify your weight, body composition, and body type to establish your metabolic rate.
Next, you give details about your daily activity and workout schedule. Then, we can calculate your ideal calorie target and macronutrient ratio for each day of the week.
Lastly, you choose your fitness goal. You can use carb cycling for fat loss, body recomposition, and even muscle gain.
After completing the questions, you’ll see your personalized carb cycling macros, including a breakdown of your low, medium, and high days.

Carb Cycling Calculator Example
At this point, you may wonder what a carb cycling plan might look like. So let me walk you through an example.
In this scenario, a 175-man works out on Monday, Wednesday, and Friday. His primary goal is to burn as much fat as possible while maintaining lean muscle. In other words, he wants to look good in a bathing suit, like we all do.
To do this, he starts the week with a high-carb day for his Monday workout. Then he eats medium carbs for his Wednesday and Friday workouts. And on his rest days, he follows a low-carb diet.

High Carb Day
On a high-carb day, the added carbohydrates fuel your workout and fill your glycogen stores to provide energy for the week ahead. In addition, the slight calorie surplus boosts your metabolism, offsetting the negative effects of dieting.
A high carb day should be 45-55% carbs, 15-25% fat, and 27-30% protein.
Some people think of high-carb days as cheat days where you can eat whatever you want. However, you should still try to hit your macro targets using mostly healthy foods.
I prefer to think of high-carb days as a strategic part of a fat-burning nutrition plan. Therefore, I call them refeed days instead of cheat days.
Medium Carb Day
On a regular workout day, you need enough carbs to replenish what you burn during exercise without spilling over. Your exact carb intake depends on your body composition, activity level, and fitness goal. But here are some guidelines.
A medium carb day should be 20-40% carbs, 30-50% fat, and 27-30% protein.
Low Carb Day
On rest days, you don’t burn as many calories or carbs. Hence, your carb intake should be lower.
At the same time, your fat intake can be higher since you burn more calories from fat on rest days.
Low carb days should be 5-20% carbs, 50-65% fat, and 30% protein.
