Carnivore Diet Calculator

A carnivore diet calculator estimates your daily macronutrient needs — protein, fat, and calories — based on your unique stats and goals. Unlike generic macro calculators, it accounts for the carnivore diet's unique zero-carb approach and lets you choose your preferred fat-to-protein ratio.

The calculator goes beyond just numbers: it translates abstract macro targets into real food portions (grams of ribeye, number of eggs, pounds of ground beef) so you know exactly what to buy and cook. Use it alongside our TDEE Calculator for a complete picture of your energy needs.

There is no single "correct" fat-to-protein ratio on carnivore — the best ratio depends on your health goals:

• Therapeutic (80/20): Very high fat, low protein. Used for neurological conditions like epilepsy or severe autoimmune issues. Most ketogenic.
• Standard (70/30): Balanced fat-to-protein ratio for general health, sustained energy, and weight maintenance. The most common approach.
• Lean (60/40): Higher protein, lower fat. Ideal for fat loss, body recomposition, or those who feel better with more protein.
• Muscle Gain (55/45): Highest protein ratio. Designed for athletes, bodybuilders, and anyone prioritizing muscle growth.

Experiment with different ratios using our Ratio Explorer in the results. If you're tracking overall calories, our Calorie Deficit Calculator can help you plan your fat loss phase.

This is the #1 question in the carnivore community. The answer depends on your protein target, which is driven by your lean body mass and activity level. Most people need between 1.0 and 1.2 grams of protein per pound of body weight.

In food terms: a 180 lb (82 kg) person targeting 180g of protein would need roughly 820g (1.8 lbs) of ribeye, 1 kg (2.2 lbs) of 80/20 ground beef, or a combination like 500g steak + 8 eggs. Our calculator's What to Eat Today section shows you these equivalents for multiple meat types.
