This free keto macro calculator will help you figure out how much fat, protein, and carbs you should eat on the keto diet for your size.
In today’s post, I am going to share everything you need to know about calculating your macros when starting a low carb diet and how to use a free keto macro calculator to do just that.
What Are Macros?
The word macros is short for macronutrients. There are three categories of macros that people need to track if they want to stay in ketosis – protein, fat, carbs.
Here is a little introduction to these three macros.
- Carbohydrates – Includes sugars, starches, and fibers. They are found in grains, starchy vegetables, beans, dairy products, and fruit.
- Fats – These have the most calories of all the macronutrients. It provides your body energy. Healthy fats are found in foods like oils, butter, avocado, fish, and nuts.
- Protein – Proteins are the building blocks of muscles. How much protein you need depends on your body’s composition, your age, and your overall health. Protein-rich foods include eggs, meat, beans, and tofu.

There are lots of factors that change how much of each macro your body needs.

Frequently Asked Questions About Keto Macro Calculators
This calculator is really simple to use and will help you understand how much to eat each day. If you have any questions about it, please leave them in the comments.
Here are some common questions most people might have about macros on the keto diet.
What is a lazy keto diet?
The lazy keto diet is one where people don’t track their macros, they just try to estimate how much of each type of food they should eat.
Calculating and tracking macros takes time – so it’s no surprise that people fall into lazy keto. The problem is that if losing weight is your goal, it’s hard to do on a lazy keto diet.
If you don’t eat enough fat, you won’t go into ketosis and your body won’t burn fat for energy.
How do I figure out my body fat percentage?
In order to get you the most accurate macros possible, you need to know your body fat percentage. If you have more body fat, you will need to eat more healthy fats. This is because it will keep you full longer and it will train your body to burn more fat as fuel.
If you have a scale that measures body fat, that is the easiest way to do it. If you don’t, you can still calculate it manually. You’ll need a measuring tape and this body fat calculator.
What is a calorie deficit?
Part of my keto macro calculator tells you how much of a deficit you should maintain in order to lose weight. A calorie deficit means that you are burning more calories than you consume.
You need to stay within a healthy deficit or else your body will go into starvation mode and lose less weight.
Why is activity level important for macros?
How active you are affects the minimum number of calories your body will burn in a day. Really active people will naturally burn more calories than sedentary people.
What is the best macro ratio for the keto diet?
Ratios change based on your activity levels and a bunch of other factors. This is why the free calculator is so important. It already figures all of that out for you and tells you the ratios based on your answers.
There are some general ratios that most people use. Here is what most people follow on keto:
- 70-80% Fat – 165 grams
- 5-10% Carbs – 40 grams
- 10-20% Protein – 75 grams
Why should I eat such a small amount of carbs?
There are lots of benefits of eating low carb foods on the keto diet.
The main idea behind this is that when your body stops burning carbs for fuel, it starts to burn fat for energy instead. This leads to weight loss and a bunch of other health benefits too.
Is eating too much protein on a low-carb diet bad?
Experts agree that a good range of protein to eat on a low-carb diet is about 0.7-0.9 grams per pound of body weight.
If you eat too much protein, it can actually prevent you from going into ketosis. Your body will start burning the protein as energy instead of fats.
