This sample table shows common keto-friendly foods and rough macro values per serving.
| Food | Serving | Calories | Protein (g) | Fat (g) | Net Carbs (g) |
|---|---|---|---|---|---|
| Eggs | 3 large | 216 | 18 | 15 | 1.8 |
| Salmon | 150 g | 312 | 33 | 20 | 0 |
| Avocado | 1 medium | 240 | 3 | 22 | 3 |
| Olive oil | 1 tbsp | 119 | 0 | 13.5 | 0 |
| Cheddar cheese | 40 g | 161 | 10 | 13 | 0.6 |
1) Basal Metabolic Rate: The calculator uses Mifflin-St Jeor when body fat is not entered. It uses Katch-McArdle when body fat is available.
2) Total Daily Energy Expenditure: TDEE = BMR × activity multiplier.
3) Goal Calories: Fat loss lowers TDEE by your chosen percentage. Muscle gain raises TDEE by your chosen percentage. Recomp uses a smaller reduction.
4) Protein: Protein grams = body weight or lean mass × protein factor.
5) Net Carbs: Net carbs are set directly by the user. Keto plans often stay between 20 and 30 grams daily.
6) Fat: Fat grams = remaining calories ÷ 9 after protein and net carbs are assigned.
A keto diet focuses on very low carbs. Protein stays moderate. Fat fills the rest of your calories. This calculator helps you estimate all three macros. It also estimates daily calories. That gives you a simple target for planning meals.
Calories still matter. Macros matter too. Keto works best when carbs stay low enough. Protein should support muscle and recovery. Fat should match your calorie goal. When one macro is off, progress can slow. This tool helps create a balanced starting point.
The calculator estimates your basal metabolic rate first. That is the energy your body uses at rest. It then applies an activity multiplier. This gives an estimated total daily energy expenditure. After that, the tool adjusts calories for maintenance, fat loss, gain, or recomposition.
You choose your daily net carbs. Keto users often stay near 20 to 30 grams. Protein is based on body weight or lean mass. This helps keep protein practical. Fat is calculated from the calories left after protein and carbs. That makes the plan flexible and easy to change.
If you know body fat percentage, add it. The calculator can estimate lean body mass. That improves protein and calorie estimates for many people. It is helpful during fat loss. It is also useful for users with more muscle or higher body fat.
Use the daily targets to build meals. You can split macros across two, three, or four meals. Review the per meal values. Compare foods with the sample table. Then track results for two weeks. Adjust calories or protein if progress stalls. These numbers are estimates, not medical advice.
Net carbs are total carbs minus fiber. Many keto plans track net carbs because fiber has less effect on blood sugar for most people.
Many people start with 20 to 30 grams daily. Your tolerance can vary. Activity, body size, and food choices also matter.
No. Protein should usually be moderate, not very low. Adequate protein supports muscle retention, recovery, and fullness.
Fat supplies most of the calories after protein and net carbs are set. That is why keto diets often show a high fat target.
It gives a solid estimate, not a guarantee. Your real needs can differ because of hormones, training, sleep, and medical factors.
Yes. Choose the fat loss goal and set a moderate deficit. Very large deficits can feel hard to sustain and may affect performance.
Enter it if you know it reasonably well. It can improve lean mass and protein estimates. Leave it blank if unsure.
Recheck every few weeks, or after meaningful weight change. Update sooner if activity, goals, or training volume changes a lot.
