Example Data Table
| Body weight | Goal | Factor | Daily range | Meals | Approximate target per meal |
|---|---|---|---|---|---|
| 60 kg | General health | 0.8 - 1.0 g/kg | 48 - 60 g | 3 | 18 g |
| 75 kg | Active lifestyle | 1.2 - 1.6 g/kg | 90 - 120 g | 4 | 26 g |
| 82 kg | Muscle gain | 1.6 - 2.2 g/kg | 131 - 180 g | 5 | 31 g |
| 95 kg | Fat loss | 1.6 - 2.4 g/kg | 152 - 228 g | 4 | 48 g |
Formula Used
The calculator first converts body weight into kilograms when needed.
Weight in kg = weight in pounds / 2.2046226218
Weight in kg = weight in stone × 6.35029318
Then it multiplies weight by the selected protein factor.
Minimum protein = weight in kg × minimum factor
Maximum protein = weight in kg × maximum factor
Suggested target = (minimum protein + maximum protein) / 2
Calories from protein = suggested target × 4
Meal targets divide the suggested daily target across meals and snacks.
How to Use This Calculator
Enter your body weight first. Choose kilograms, pounds, or stone. Select whether the calculation should use current weight or target weight.
Next, choose a protein goal. Use general health for a basic estimate. Use active lifestyle for regular exercise. Use muscle gain or fat loss for higher targets.
Enter your meals and snacks. Select the snack split option when snacks should be smaller than main meals. Press the calculate button. The result appears above the form.

Body Weight and Protein Planning
Why protein targets matter
Protein planning becomes easier when it starts with body weight. A clear number removes guesswork. It also helps meals stay consistent during training, fat loss, or general wellness. This calculator gives a practical daily range instead of one fixed number.
Choosing the right range
Different goals need different protein levels. A person with light activity may need a lower range. A person lifting weights may need more. Fat loss plans often use higher protein because meals must feel filling. Endurance training can also raise needs because recovery matters after long sessions.
Using current or target weight
The calculator can use current weight or target weight. Current weight is simple. Target weight can be useful when the present weight is far from the planned weight. This keeps the estimate practical and easier to apply.
Meal distribution
A daily protein number is only helpful when it fits meals. The calculator divides the target across meals and optional snacks. This helps build a simple eating pattern. You can place more protein at breakfast, lunch, dinner, or after training.
Protein calories
Protein provides about four calories per gram. The tool converts the suggested protein target into calories. This is useful when building a calorie plan. It also helps compare protein with carbohydrates and fats.
Practical use
Use the result as a planning guide. Then adjust based on appetite, digestion, food preference, training load, and professional advice. Very high protein targets may not suit everyone. People with medical conditions should ask a qualified clinician before changing diet.
FAQs
What does this calculator measure?
It estimates daily protein needs from body weight. It also shows protein ranges, meal targets, snack targets, weekly totals, and calories from protein.
Which unit can I use?
You can use kilograms, pounds, or stone. The calculator converts the entered value into kilograms before applying the protein formula.
What is grams per kilogram?
Grams per kilogram means protein grams for each kilogram of body weight. For example, 75 kg at 1.6 g/kg equals 120 grams daily.
Should I use current weight or target weight?
Use current weight for a direct estimate. Use target weight when your present weight is far from your goal or your diet plan needs a practical target.
Is more protein always better?
No. More is not always better. Your ideal amount depends on goals, health, appetite, training, calories, and digestion.
How are protein calories calculated?
The calculator multiplies protein grams by four. This gives estimated calories from protein for the suggested daily target.
Can I use this for fat loss?
Yes. Select the fat loss profile. It uses a higher range because protein can support fullness and help preserve lean tissue.
Can I export my result?
Yes. Use the CSV button for spreadsheet data. Use the PDF button for a simple printable result summary.
