What is a Keto Calculator?
A keto calculator, also known as a ketogenic macro calculator, is a specific online tool created to assist people on a keto or low-carb diet in figuring out their unique daily macronutrient needs. Macronutrients, or macros, refer to the three main nutrients that provide calories and energy to the body: carbohydrates, proteins, and fats.
Understanding Macros: Proteins, Carbs, and Fats
The term macro comes from "macro-nutrient" and refers to the three building blocks that humans get calories from. These are proteins, carbohydrates, and fats.
This free keto macros calculator will help you determine how much of each macronutrient you need daily to achieve your goals. Calculating your macros is essential whether you are trying to lose, gain, or maintain weight.
Proteins
Protein provides the body with essential amino acids that it can't make on its own, directly or indirectly. Your protein intake helps you build and retain muscle mass, slows the digestion of other nutrients (preventing blood sugar spikes), and allows your body to utilize glucose as fuel.
Fats
Fats are the densest form of energy, meaning it takes more space to store fat than either protein or carbohydrates. You can get fats from various animal and plant sources. Some of the most common types of fat on a keto diet are dairy, meat, seafood, chocolate, olives, oils, etc.
Carbohydrates
Carbohydrates are your body's preferred form of energy because they are less dense than fats and easily accessible. When you eat carbohydrates like bread, potatoes, or pasta, your body stores them in the liver and muscles, converting them into glucose to fuel your brain.
Most plant-based foods contain carbohydrates, with some, like leafy greens, also high in fiber. A low-carb keto diet aims to train the body to use fats for energy, promoting ketosis and allowing you to burn fat instead of using carbs for fuel.
Fiber
Fiber is a non-digestible carbohydrate from plants and is excreted by your body without breaking down. Soluble and insoluble fiber provide health benefits such as preventing constipation and regulating blood glucose levels. To calculate net carbs, simply subtract the amount of fiber from the total carbohydrates.
What is a keto diet?
The ketogenic diet, commonly known as the keto diet, is a popular nutrition plan that emphasizes low carbohydrate intake, high-fat consumption, and moderate protein intake. The main objective is to shift the body's primary source of energy from carbohydrates to fats, resulting in a state known as ketosis.
Ketosis occurs when the body's carbohydrate stores are significantly reduced, increasing the production of molecules called ketones in the liver. These ketones are an alternative energy source for the brain and body when glucose (derived from carbohydrates) is limited.
To achieve and maintain ketosis, individuals following the keto diet typically restrict their daily carbohydrate intake to a minimal level. Doing so forces the body to utilize stored body fats for fuel, leading to potential weight loss goals and keeping the carb content in check.
The key principles of the keto diet include:
How to start a keto diet?
Embarking on a keto diet can be a transformative journey toward achieving your health and weight goals. Here's a step-by-step guide to help you get started:
- Educate yourself: Before diving into the keto lifestyle, learn about the principles and science behind the diet. Understand the macronutrient ratios (low carb, moderate protein, high fat) and how ketosis works in the body.
- Consult a healthcare professional: It's essential to consult with a qualified healthcare professional or a registered dietitian before starting any new diet plan. They can assess your health status and provide personalized recommendations based on your unique needs and medical history.
- Set clear goals: Define your health objectives and personal goals for following the keto diet, whether it's weight gain or loss, improved energy levels, or better metabolic rate.
- Clean out your pantry: Remove high-carb and sugary foods to avoid temptation and stay committed to your new eating plan. Stock up on keto-friendly foods like healthy fats, low-carb vegetables, and protein sources. Our Keto Pantry Guide will help you understand what you need to stock!
- Use a keto macro calculator: To determine your ideal macronutrient intake, use a keto macro calculator. It will determine your daily caloric needs and the required amounts of fat, protein, and carbohydrates to reach your objectives.
- Gradually reduce carbs per day: Instead of drastically cutting carbs overnight, gradually reduce your carbohydrate intake over a few days to allow your body to adjust. Aim to keep your daily net carb intake below 50 grams to initiate ketosis.
- Monitor your progress: Keep track of your daily food intake and monitor how your body responds to the keto diet. Adjust your meals and macros as needed to achieve optimal results.

Understanding your results
Many people underestimate the importance of adequate protein intake and overestimate their carbohydrate needs when following a high-fat diet. Our free keto calculator helps you better understand your body's requirements, empowering you to make informed dietary choices.
Please note:
A word on caloric intake
Calorie intake adjustment is vital for overall health and well-being. Consuming a few calories can have severe consequences, affecting your energy levels and even leading to muscle loss, especially if you're exercising regularly.
Even if you are on a weight loss journey, avoid a calorie deficit diet, as it may hinder your progress and compromise your ability to maintain muscle mass.
For women, it is recommended not to go below 1200 calories per day, and for men, not to go below 1800 calories per day. Increase your caloric intake if you experience rapid weight loss or feel dizzy frequently.
Remember, balancing calorie intake, macronutrient ratios, and regular physical activity is key to successful and healthy weight management.
How to achieve your macronutrient goals?
Mastering your macronutrient goals on a ketogenic diet is vital for staying in ketosis and reaping its benefits. To successfully achieve your keto macros, follow these three essential steps:
Now that you have a solid plan to achieve your keto macro targets, here are some keto-friendly foods that can become staples in your diet:

Anita says
I don't understand the graph. Week one is the highest level of all macros, at the end, it's much lower. Why is that?
Cast Iron Keto says
Hey Anita - So, if you're calculating to lose weight, as you do your needs go down as your weight goes down. At some point, you'll need to increase activity so that you can reliably stay above the recommended calorie baseline. Does that make sense? It's helpful to see the graph but as you lose weight, or gain, or maintain, the best thing would be to come back and recalculate. Hope that makes sense!
Sara says
I'm having the same issue.
Donna Gibson says
I used the calculator and I’m confused. The recommended intake of macros in calories per day is far under the calculated calorie intake. My calorie suggestion is over 1500 but when I add up the recommended calories under each macro section the calories only add up to less than 600 per day. Clarification? Am I looking at it the wrong way? The percentages seem correct at 75%, 5%, and 20%.
Cast Iron Keto says
Hi Donna, we have tried to replicate your issue this morning to no avail. We're not sure what's happening. When we use the calculator, the first calorie suggestion is your daily BMR. Then, after choosing the weight-loss rate, the calorie suggestions under each macro breakdown changes according to that variable. If you give it a try again and get the same results, take a screenshot and shoot it over to [email protected] and we'll take a look.
Brian Roscher says
Does the recommended carbs intake refer to dietary fiber plus simple carbs or just simple carbs?

Why is the calculator not working ... I can't enter anything?

Nevermind... I had to go into full screen to see all
Shaz McGill says
Ok so I'm 59 years old, 136 lbs - 5'5" my fat percentage is 28.67 - I want to get back down to 120 lbs - the weight I have maintained most of my adult life. I want to lose by March 31st (60th bday ) - so I chose the strict 2lbs loss/week. In order to maintain my 136 lbs is says 1908 kcal/day. In order to lose 16 lbs of weight - Fat 681/kcal, Carb 45.42/kcal, Protein 181.7 kcal = 908.12 kcal per day and the graph has me going down to about 800 kcal by week 8. Is that not too low/drastic? Do I just stay at the 908.12 kcal for the 8 weeks or do I continue to cut back - sorry confused. What do I do to maintain after week 8? It says not to go below 1200 kcal/day for women.
