Ketogenic Macro Calculator
Calculate your daily fat, protein, and carb targets for a ketogenic diet. Standard keto ratios are roughly 70-75% fat, 20-25% protein, and 5-10% carbs of total daily calories.

Step-by-Step Examples
Example 1
Standard 2000 cal Keto
2000 cal/day, default ratios.
- Carbs: 5% × 2000/4 = 25g (100 cal)
- Remaining: 1900 cal
- Protein: 25% × 1900/4 = 119g (475 cal)
- Fat: (1900-475)/9 = 158g (1425 cal)
✓ Fat 158g | Protein 119g | Carbs 25g
Example 2
Strict 1500 cal Keto
1500 cal/day, carb limit set to 20g.
- Carbs: 20g fixed = 80 cal
- Remaining: 1420 cal
- Protein: 25% × 1420/4 = 89g
- Fat: remaining/9 = 119g
✓ Fat 119g | Protein 89g | Carbs 20g
Example 3
Higher-Protein Keto
2200 cal/day for active individual, want more protein.
- Using standard 5% carb: 27g carbs
- Remaining for higher protein split would need custom ratio
- Standard calc gives: Fat 173g, Protein 131g, Carbs 27g
✓ Fat 173g | Protein 131g | Carbs 27g
Real-World Applications
Ketogenic Diet Planning
Daily macro targets are the foundation of successful keto dieting.
Athletic Keto
Active keto dieters often need protein adjustments above the standard 25%.
Diet Tracking Apps
MyFitnessPal, Carb Manager, and similar apps use this ratio logic for keto mode.
Therapeutic Keto
Medically supervised ketogenic diets for epilepsy use precise macro ratios.
Common Mistakes to Avoid
⚠️
Eating too much protein on keto
Excess protein can be converted to glucose (gluconeogenesis), potentially slowing ketosis. Stick close to the 20-25% protein target.
⚠️
Not tracking carbs precisely
Even small carb overages (10-15g extra) can kick some people out of ketosis. Use a food scale and tracking app for accuracy.
⚠️
Assuming all fat sources are equal
Quality matters: prioritize healthy fats (olive oil, avocado, nuts) over excessive processed/saturated fat for long-term health.
Frequently Asked Questions
What is the standard keto macro ratio? ▾
Roughly 70-75% fat, 20-25% protein, 5-10% carbs of total calories. This translates to about 20-50g net carbs per day depending on individual tolerance.
Why is protein moderate, not high, on keto? ▾
Very high protein intake can trigger gluconeogenesis (protein converted to glucose), potentially reducing ketone production. Moderate protein keeps the diet 'ketogenic.'
How long does it take to enter ketosis? ▾
Typically 2-4 days of strict carb restriction (under 20-50g/day), though it varies by individual glycogen stores and metabolic flexibility.
Is keto safe for everyone? ▾
No — people with certain conditions (pancreatitis, liver disease, some metabolic disorders) should consult a doctor first. Pregnant or breastfeeding individuals should also seek medical guidance.
What are keto-friendly fat sources? ▾
Olive oil, avocado, butter, coconut oil, nuts, seeds, and fatty fish. Aim for a mix of saturated, monounsaturated, and polyunsaturated fats.
