Build keto macros from calories, activity, and goals. Review protein, fats, net carbs, and BMI. Download clean reports and compare sample diet targets easily.
| Profile | Goal | Calories | Protein | Net Carbs | Fat |
|---|---|---|---|---|---|
| Office worker, 72 kg | Fat loss | 1850 | 115 g | 25 g | 127 g |
| Trainer, 82 kg | Maintenance | 2550 | 148 g | 30 g | 190 g |
| Athlete, 90 kg | Lean gain | 3050 | 180 g | 40 g | 223 g |
Male BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) + 5
Female BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) − 161
TDEE = BMR × activity factor
Target Calories = TDEE × (1 + goal adjustment ÷ 100)
Protein = body weight or lean mass × selected protein factor
Net carbs follow the keto style selected. Custom mode uses your own value.
Fat grams = (target calories − protein calories − carb calories) ÷ 9
BMI = weight in kg ÷ (height in meters × height in meters)
Water liters = body weight in kg × 0.033
Keto meal planning works best with numbers. Guesswork often leads to hidden carbs, low protein, or excess calories. This calculator reduces that problem. It estimates daily energy needs first. Then it turns that number into keto-friendly macro targets. You can review calories, fat, protein, net carbs, BMI, lean mass, and water guidance in one place.
A keto pattern usually keeps net carbs low. That helps many people stay in nutritional ketosis. Calories still matter, though. Protein also matters. Too little protein may reduce muscle support. Too many calories may slow fat loss. The calculator helps balance these moving parts with one clear result block.
The form supports metric and imperial entries. It also includes age, sex, height, weight, activity, and goal. You can add body fat if known. That improves lean mass estimates. You can also choose strict, standard, liberal, or custom keto carb limits. Protein settings can stay standard or move higher for training phases.
The calorie estimate starts with basal metabolic rate. This is the energy used at rest. The tool then applies an activity factor. That gives total daily energy expenditure. A goal adjustment is applied next. Fat loss lowers the target. Maintenance keeps it near baseline. Muscle gain adds calories carefully.
Macronutrients are built from that calorie target. Protein is estimated from body weight or lean mass. Net carbs come from the selected keto style. Fat fills the remaining calories. This method keeps the plan practical. It also keeps the math transparent. You can change assumptions and compare outcomes quickly.
Use the results as a planning guide. They are not a diagnosis. Real needs vary by training load, age, medicines, stress, sleep, and medical history. Review labels, track net carbs honestly, and monitor progress for two or three weeks. Then update inputs if body weight, activity, or goals change. Small adjustments usually work better than extreme changes.
Many users also want a simple export step. That is useful for coaching, meal prep, and personal review. The included CSV and PDF actions support that workflow. The sample table below shows how daily targets may look for different goals. It helps you compare conservative and aggressive approaches before changing your meal plan.
Consistency matters more than perfect numbers.
It estimates daily calories, protein, fat, net carbs, fiber, BMI, lean mass, water intake, and meal splits. It is designed for planning, not diagnosis.
Most keto plans focus on net carbs. Net carbs usually mean total carbs minus fiber. This calculator shows net carbs and also gives an estimated total carb figure.
Protein helps preserve lean mass during fat loss and supports recovery. Many keto plans fail because protein is set too low. This tool makes protein a clear part of the plan.
No. The calculator works without it. If you know body fat, the lean mass estimate improves. That can make protein targets more personal.
Update them when body weight changes, training volume changes, or your goal changes. Many people review targets every two to three weeks for steady progress.
No. It is an educational planning tool. People with diabetes, kidney issues, pregnancy, or prescription medicines should speak with a qualified clinician first.
Low carbs can change appetite, but energy balance still matters. Calories help explain why progress stalls, speeds up, or changes when portions shift.
Yes, but they may need higher protein, more total calories, and sometimes higher carbs depending on training demands. Custom protein and carb options help test those setups.
