About the Protein Intake Calculator
What is protein and why do you need it?
Protein is a nutrient that builds and repairs muscle, skin, enzymes and hormones. Your body does not store protein the way it stores fat, so you need some every day.
The Indian Council of Medical Research and National Institute of Nutrition (ICMR-NIN) sets the protein recommendation for healthy Indian adults at 0.83 grams per kilogram of body weight per day. This is the Recommended Dietary Allowance (RDA) for good-quality protein.
Pregnant women in the second and third trimesters and breastfeeding mothers need extra protein each day. The tool adds these amounts automatically when you select the right option.
If you have kidney disease, your protein needs are different. Do not use this tool to set a target; speak to your nephrologist or dietitian first.
- Protein supports muscle, immunity and healing
- RDA for healthy adults is 0.83 g per kg body weight
- Extra protein needed in pregnancy and lactation
- Kidney disease changes protein needs
How the calculator works
You enter your weight, age group, sex, activity level and life stage (such as pregnancy or breastfeeding). The tool applies the ICMR-NIN formula to show your daily protein target in grams.
Then you choose food items and the amounts you eat. The tool uses Indian food composition values per 100 grams of raw edible portion. It adds up the protein from each item and compares the total to your target.
Cooking changes water content, so protein per 100 grams of cooked food differs from raw values. The tool uses raw values unless a cooked option is shown.
- Weight in kilograms
- Age, sex and activity level
- Life stage: adult, pregnant, breastfeeding
- Food items and amounts eaten
Steps to use the tool
Enter your details, pick the foods you ate or plan to eat, and read the result. You can change any entry and the totals update at once.
- Type your weight in kilograms
- Select your age group, sex and activity level
- Choose pregnant or breastfeeding if it applies
- Pick a food from the list and enter the amount in grams
- Add more foods as needed
- See your total protein and how it compares to your target
Understanding your result
The tool shows your daily protein target and the total protein from the foods you entered. It also shows the gap or surplus.
Use this to see if your meals usually meet the target. If there is a gap, you can add a serving of dal, curd, egg or milk to the next meal and check again.
The number is an estimate for a healthy person. A doctor or dietitian reads it alongside your medical history, blood reports and overall diet.
- Target grams per day based on ICMR-NIN
- Total grams from your food entries
- Gap or surplus shown clearly
- Not a prescription; discuss with a professional
Tips for accurate entries
Small changes in how you measure food make the totals more useful. Weigh raw ingredients when you can, or use standard cup and spoon measures for cooked items.
Combine cereals and pulses in roughly a 3 to 1 ratio by raw weight to get all essential amino acids. Adding milk or curd improves protein quality further.
Spread protein across meals rather than eating it all at once. Physical activity helps your body use the protein you eat for muscle maintenance.
- Weigh raw dal, rice, flour and paneer before cooking
- Use the same bowl or cup each time for cooked items
- Include milk or curd daily if you are vegetarian
- Eat some protein at each main meal
- Stay active so the protein is used for muscle
What this tool cannot tell you
The calculator is for general information for healthy people. It does not cover medical conditions that change protein needs, such as kidney disease, liver disease, burns, surgery recovery or critical illness.
Food values are averages; actual protein in your kitchen may vary by variety, brand or preparation. The tool does not give a meal plan, diagnose deficiency or excess, or replace advice from a qualified professional.
- Not for kidney disease or other medical conditions
- Does not account for protein quality in every meal
- Food database values are averages only
- No meal plan or supplement advice given
- Cannot diagnose protein deficiency or excess
When to see a doctor or dietitian
See a doctor or dietitian if you have a medical condition, are losing weight without trying, feel weak, have swelling in the feet, or notice changes in urine output. These may need a specific protein prescription.
Pregnant and breastfeeding women should discuss their diet at each antenatal or postnatal visit. If you are planning a high-protein diet or supplements, get medical advice first.
- Kidney, liver or other chronic illness
- Unplanned weight loss or muscle wasting
- Swelling in feet or face
- Changes in urine amount or colour
- Before starting protein supplements
In an emergency, call 7414 001 001 or go to the emergency department.

Common questions about the Protein Intake Calculator
How much protein does a healthy Indian adult need each day?
The ICMR-NIN recommendation is 0.83 grams of good-quality protein per kilogram of body weight per day.
Your exact target depends on your weight, sex, activity level and life stage.
Can I meet my protein needs with only vegetarian food?
Yes.
Combining cereals and pulses in a 3 to 1 ratio by raw weight, and including milk or curd daily, provides all essential amino acids. The tool includes common vegetarian items like dal, paneer, soy and millets.
Does the calculator use raw or cooked food values?
The tool uses values per 100 grams of raw edible portion unless a cooked option is shown.
Cooking changes water content, so protein per 100 grams of cooked food will differ from the raw value.
Is it safe to eat more protein than the target shown?
For healthy adults, a moderate surplus from food is usually well tolerated.
Very high intakes over long periods, especially from supplements, may strain the kidneys. If you have kidney disease, do not exceed the target without your nephrologist's advice.
Do I need protein powder to build muscle?
No. ICMR-NIN guidance states most people can meet protein needs through food alone.
Muscle growth also needs enough carbohydrates and fats for energy, plus regular strength exercise. Protein powder is not necessary for normal healthy life.
Should I use this tool if I have kidney disease?
No. Protein needs in kidney disease are different and must be set by your nephrologist or dietitian.
This tool is for general information for healthy people only.
