How This Macro Estimator Works
The Keto Macro Calculator uses the Mifflin-St Jeor equation to calculate your Basal Metabolic Rate (BMR) and then applies a ketogenic multiplier. Unlike standard diet calculators, this tool prioritizes fat-adaptation by keeping glycogen levels low enough to trigger the production of ketones.
How to Use the Calculator
- Protein: Set based on your lean body mass to prevent muscle wastage (0.6g to 1.0g per lb).
- Carbohydrates: Usually kept at a hard limit of 20g to 30g for beginners.
- Fat: The remaining calories come from fat to provide energy and hormonal support.
If you weigh 180 lbs and have a desk job:
- Goal: Weight Loss
- Calculated Macros: 1,650 kcal
- Split: 128g Fat / 103g Protein / 20g Net Carbs
In this scenario, hitting the protein goal ensures you lose fat, not muscle, while the fat
keeps your hunger hormones (ghrelin) suppressed throughout the workday.
Keto Macro Strategy FAQ
While a process called gluconeogenesis can convert protein to glucose, you would have to eat massive amounts of lean meat for this to kick you out of ketosis. For most people, high protein is safe and beneficial.
Net carbs = Total Carbs - (Fiber + Sugar Alcohols). On Keto, we only count carbs that impact blood glucose. Fiber passes through the body undigested.
Many people use Keto for years for metabolic health. However, focus on 'Clean Keto' (whole foods) rather than 'Dirty Keto' (processed meats and snacks) for the best long-term results.
