📌Carnivore Presets
Presets load different body sizes, activity levels, goals, carb caps, protein factors, and food profiles so the outputs are easy to compare.

💡Tips
The carnivore diet involve the consumption of meats, eggs, and animal fat. It can be difficult for an individual to determine the amounts of meat, eggs, and animal fat that they needs to consume each day to meet their goals. If an individual does not use a method to calculate these numbers, the individual will have to guess the amount of food that they will consume each day.
Guessing at the amount of food that will be consumed will result in the individual not meeting their dietary goal. The calculator that is provided here will use your body statistics, your activity level, and the carnivore diet style that you would like to follow to calculate the amount of calories that you should consume daily, the amount of protein that you should consume daily, and the amount of fat that you should consume daily. Additionally, the calculator will estimate the total weight of the food that you will have to consume to reach these targets for calories, protein, and fat.
How to Use the Carnivore Diet Calculator
This calculator isnt used to force you to consume a certain amount of food. Instead, it is provided as a starting point for you to adjust the amount of food that you consume to ensure that you are feeling well and have the desired weight. Body fat percentage is an important measurement in the calculation that you will perform.
Your body fat percentage will allow the calculator to separate your lean body mass from your fat body mass. The calculator will calculate the target for protein from your lean body mass because protein is used to maintain your lean body mass, not your fat body mass. If you do not input your body fat percentage, the calculator will assume that all of your weight is made up of lean body mass.
If your body fat percentage is higher than ten percent of your total body weight, then your protein target will be calculated inaccurately. Your activity level and training will play a big role in the calculation of the energy that you should consume daily. The calculator will use your resting metabolic rate and multiply that number by your activity level to determine your energy needs.
The number of days that you train will also impact your total energy needs. The more days that you train, the more energy that your body will need to support that activity. However, the difference between training for four days each week as opposed to six days each week may be small.
Even if the number of days that you train changes, it will have an impact on your fat target that you plan to consume each week. The goal that you follow will impact your energy targets. If your goal is losing fat mass, then you will reduce the number of calories that you consume, but you will increase the amount of protein that you consume to maintain your lean body mass.
If your goal is gaining lean body mass, then you will increase the number of calories and the amount of fat that you consume to provide the energy needed to increase the size of your lean body mass. If your goal is to recompose your body (increasing lean body mass while decreasing fat mass), then the calculator will estimate a value in the middle of these two extremes. This calculator will not determine how long you should follow your selected goal.
Instead, the calculator will provide you with a calculation of your energy and macronutrient needs if you can maintain your selected goal for a few week. Your carnivore diet style will also have an impact on the ratio of fat to protein that you consume. If you select lean meat as your carnivore diet style, you will need to consume more total meat to reach your target calorie intake.
If you select fatty meat, like ribeye steak, as your carnivore diet style, you will need to consume less total meat to reach your target daily calorie intake. The food-profile selector will show the total weight of the food that you will have to consume daily to reach your targets. The protein-floor priority will change the amount of protein that you consume daily.
If the protein floor that you select is high, then the calculator will generate a higher target of protein for you that will allow you to feel more fully when consuming fewer calories than your body requires. If you select a moderate protein floor, then you will consume the same amount of protein daily as those targets are established for an individual maintaining their current body composition. The trace carbohydrates setting is another that you should use when calculating your macronutrients.
Most carnivores consume between zero and ten grams of carbohydrates daily from sources like eggs and connective tissue. It is important for you to enter the number of trace carbohydrates that you consume daily because if the number of carbohydrates isnt accurate, the fat target that the calculator generates will not be accurate as well. An incorrect fat target will lead to incorrect feelings of hunger and energy levels.
The reference tables located on this page will show you the ranges of the calculations that are used in the calculator. Protein targets will range based on your goals. The goal adjustments will demonstrate the change in the amount of calories that you will consume if you are attempting to follow a fat-loss diet or a lean-gain diet.
The food macro profiles will show you the changes in protein and fat amounts if you choose to cook your food or trim some of the meat that you consume. Do not use these tables as rules for your diet. Always read the labels of the food products that you decide to purchase.
Some of the most common mistake with this calculator are using it as a permanent prescription for the amount of food that you will eat daily. You should always recheck the calculation if your weight or training changes. Another of the most common mistakes is to ignore the changes in the nutritional value of the meat due to the method in which you cook the meat or trim it.
The calculator will not provide you with an accurate estimation of the fat content of the meat if you trim it. The most value of using this calculator is that it will force you to consider the connection between your diet and the food that you consume. If the weight of the food that is calculated is too high for your budget, you can alter the protein floor or the fat content of the meat that you consume.
The targets will not always be the same as the initial calculation. Your appetite, digestion, and sleep cycles will change over time. The calculator will provide you with a starting point for your carnivore diet, and it will provide a way for you to update the calculation if your bodys signal to you change.
