Keto Macro Calculator: How to Find Your Perfect Ratios
Getting your macros right is fundamental to keto success. Too many carbs and you stay out of ketosis. Too little protein and you lose muscle. Here is how to dial in your perfect ratios.
The Standard Keto Macro Split
The classic ketogenic ratio: 70–75% calories from fat, 20–25% from protein, 5% from carbohydrates. This translates roughly to 165g fat, 113g protein, and 22g net carbs per day for a 2,000 calorie diet.
Step 1: Calculate Your TDEE
Total Daily Energy Expenditure is the number of calories you burn each day. Use your height, weight, age, and activity level to calculate this.
Step 2: Set Your Calorie Target
For fat loss: eat 10–20% below TDEE. For maintenance: eat at TDEE. For muscle building: eat at or slightly above TDEE.
Step 3: Set Your Carbs First
Fix carbs at 20–50g net per day. This is non-negotiable for ketosis.
Step 4: Set Your Protein
Target 0.8–1.2g protein per pound of lean body mass. Too much protein can be gluconeogenic (converted to glucose).
Step 5: Fill Remaining Calories With Fat
After setting carbs and protein, fat fills the remaining calories. This is your energy currency on keto.
