Carnivore Calculators
Free calculators built for the carnivore and high-protein community.
Most nutrition calculators assume you eat grains, fruit, and vegetables, and they are awkward to use when you do not. These tools are built the other way around. They start from meat, eggs, seafood, organ meats, and dairy, use practical US serving sizes like ounces, patties, and eggs, and answer the questions people on a carnivore, ketovore, or high-protein diet actually ask: how much protein do I need, how much did I just eat, which cut is the best value, and how do I keep my electrolytes right.
Every tool runs entirely in your browser. There is nothing to install, no account to create, and nothing to sign up for. Nutrient values come from the USDA FoodData Central database and are built into the pages, so results appear instantly and work the same on a phone in the grocery store as on a laptop at home. Where a tool produces a result you might want to keep, it is encoded in the page address so you can bookmark it or share it.
Protein Target Calculator
Enter your current weight, an optional goal weight, and your activity level to get a daily protein target in grams. The result is compared against the USDA daily RDA and translated into everyday foods so you can see what the number looks like on a plate. Start here if you are new to carnivore or high-protein eating and do not yet know how much to aim for.
Meal Protein Counter
Tap foods from a curated list of animal-based items covering beef, pork, poultry, seafood, organ meats, eggs, and dairy, and watch your running protein, fat, and calorie totals build against a daily target you set. Your log is encoded in the page address, so you can bookmark or share it without an account. Useful at the table when you want to know whether you have hit your number yet.
Meat Value Calculator
Pick a cut, choose its USDA grade (Prime, Choice, Select, or unlabeled), and enter the price per pound on the package in front of you. The tool works out protein per dollar after cooking yield, so a cheap cut with a lot of bone or shrinkage does not fool you. Built for the meat counter, where you are comparing two packages and need a quick answer.
Electrolyte Calculator
Enter your body weight, pick your activity level and climate, and get daily target ranges for sodium, potassium, and magnesium. Each mineral comes with a list of carnivore-friendly foods that supply it, plus a sortable table of electrolyte content in common animal foods. Read this one if you are dealing with keto flu symptoms, cramps, or fatigue in the first weeks of a low-carb diet.
Smoking Time Calculator
Choose one of 16 cuts, enter the weight and your smoker temperature, and get an estimated cook time, target internal temperature, and rest time. The calculator flags the stall on cuts that hit it, and a serve-time planner tells you when to start so dinner is ready when you want it. A quick-reference table lists every cut at its standard smoking temperature.
Exercise Fat Burn Estimator
Choose an activity and duration, or switch to watch mode and enter the calories, time, and distance from your fitness tracker, and see the estimate in grams of body fat rather than calories. Results also show how much energy likely came from glycogen and protein, and translate the fat burned into familiar foods like eggs and butter. Built for carnivore and keto dieters who think of energy as fat, not calorie counts.
Protein Label Decoder
A reference page explaining what the labels on meat, eggs, and fish actually mean, including grass-fed versus grass-finished, organic, pasture-raised, free-range, cage-free, wild-caught, and "natural". It also breaks down the USDA grades Prime, Choice, and Select by intramuscular fat, and ends with a quick decision guide for which claims are worth paying more for. For anyone standing in the store wondering whether the premium label changes what is in the package.
Hidden Carbs in Dairy
Tap the dairy you ate today, adjust the serving counts, and see the carb total build against a keto threshold. Lactose is a sugar, and milk, yogurt, cream, and soft cheeses can add up faster than most people expect on an otherwise animal-based diet. Use it if you include dairy on carnivore or keto and want to know whether it is quietly pushing you out of ketosis.
Organ Meat Nutrient Comparison
A side-by-side table of beef liver, chicken liver, lamb liver, beef heart, kidney, tongue, and brain, covering calories, protein, fat, and the micronutrients organ meats are known for, including vitamin A, B12, iron, zinc, copper, selenium, folate, riboflavin, CoQ10, and DHA and EPA. A best-for-each-goal section points you to the organ that fits what you are trying to fix. Useful if you are adding organ meats and want to know which one earns its place.
Protein in Meat — Reference Chart
A sortable table of protein per serving for more than 30 meats, eggs, and dairy items, with columns for serving size, protein, fat, calories, and protein per ounce. Sort by any column to find the densest protein sources or the leanest. A rules-of-thumb section at the end gives carnivore dieters quick mental math for estimating protein without looking anything up.
How these tools are built
The protein, fat, calorie, and micronutrient figures behind the meal counter, protein chart, hidden carbs counter, electrolyte table, and organ meat comparison come from USDA FoodData Central. The exercise estimator uses MET values from the Compendium of Physical Activities. Smoking times and target temperatures are reference values for each cut at a standard smoker temperature, adjusted for the weight and temperature you enter. USDA grade definitions for Prime, Choice, and Select are the published intramuscular fat ranges.
Nutrient values vary by brand, cut, and preparation, and every calculator here produces an estimate, not a prescription.

If you have a medical condition, are pregnant or breastfeeding, or are considering a significant change to your diet, talk to your healthcare provider first.
