Your Estimated Daily Protein Requirement
You may need approximately [XX] grams of protein per day.
This result is a general estimate for healthy adults. Your actual requirement may differ depending on your health, body composition, diet, training routine and specific goals.
How Much Protein Do You Need Per Day?
For healthy Indian adults, the ICMR-National Institute of Nutrition recommends 0.83 g of protein per kilogram of body weight each day when the diet contains good-quality protein.
For a predominantly cereal-based diet with lower protein quality, ICMR-NIN provides a reference of 1 gram per kilogram per day. These figures are population-based reference values rather than fixed targets for every individual.
How to Calculate Your Daily Protein Requirement
A basic body-weight estimate uses the following formula:
Body weight in kg × protein requirement in g/kg = daily protein requirement in grams
For example, the ICMR-NIN reference for a healthy adult consuming good-quality protein is 0.83 g/kg per day. For an adult weighing 60 kg:
60 × 0.83 = 49.8 g, or approximately 50 g of protein per day.
Body weight provides a useful starting point, but it does not determine the complete requirement. Age, activity level, body composition, diet quality, training goals and medical conditions may affect the amount a doctor or dietitian recommends.
Protein Requirement Based on Body Weight
| Body Weight | At 0.83 g/kg per Day | At 1 g/kg per Day |
| 50 kg | About 42 g | 50 g |
| 60 kg | About 50 g | 60 g |
| 70 kg | About 58 g | 70 g |
| 80 kg | About 66 g | 80 g |
When Protein Needs May Be Different
The general adult reference may not be suitable during certain life stages, training programmes or health conditions. In the following situations, the calculator result may require professional adjustment:
| Situation | How Protein Needs May Change |
| Regular or intensive exercise | Many exercising adults may require between 1.4 and 2.0 g/kg per day, depending on the type and intensity of training, calorie intake and fitness goals. |
| Older age | Many older adults may require at least 1 g/kg per day to help maintain muscle mass and physical function. The amount should be adjusted according to health, activity and nutritional status. |
| Pregnancy | ICMR-NIN recommends adding 9.5 g per day during the second trimester and 22 g per day during the third trimester to the adult requirement. |
| Breastfeeding | ICMR-NIN recommends adding 16.9 g per day during the first six months and 13.2 g per day from 6 to 12 months. |
| Childhood or adolescence | Protein requirements vary with age, gender, body weight and growth. An adult protein calculator should not be used for anyone younger than 18 years. |
| Recovery from illness, injury or surgery | Serious illness, burns, major injuries, surgery and undernutrition may increase protein needs to support healing and recovery. |
| Kidney or liver conditions | Protein intake may need to be controlled or adjusted according to the condition, organ function and treatment. People receiving dialysis may have different needs from those with chronic kidney disease who are not on dialysis. |
| Underweight or obesity | A calculation based only on current body weight may not provide a suitable target. A dietitian may also consider body composition, nutritional status and treatment goals. |
The exercise range is intended for people who train regularly and should not be treated as the standard requirement for every adult. Individual targets may differ, particularly during pregnancy, illness, competitive training or the management of a medical condition.
Protein Intake for Weight Loss?
Getting enough protein while losing weight can help you maintain muscle as you reduce your overall calorie intake. Research suggests 1.2–1.6 g/kg/day may be useful in a higher-protein weight-loss plan, but the right amount varies. Eating more protein on its own does not guarantee weight loss.
If you are unsure how to plan your meals, Graphic Era Hospital’s Nutrition & Dietetics Department provides individual weight-management guidance.
Protein Intake for Muscle Gain?
People who exercise regularly, especially those doing strength training, may need more protein than the general adult allowance. According to the International Society of Sports Nutrition, 1.4–2.0 g of protein per kilogram of body weight per day is sufficient for most people who exercise regularly. Training and eating enough food overall also matter; simply increasing protein will not build muscle without them.
How Does Your Protein Requirement Change With Age?
As people get older, eating enough protein becomes particularly useful for maintaining muscle and physical function. An expert group recommends 1.0–1.2 g/kg/day for healthy adults over 65. Needs may differ during illness or recovery, so an older adult with a poor appetite or recent weight loss should seek individual advice.
Protein-Rich Foods for Indian Meals
Protein can come from plant and animal foods. A balanced Indian diet may include pulses, beans, milk, curd, paneer, soy, eggs, fish, poultry, nuts and seeds according to individual preferences.
| Food | Example Serving | Approximate Protein |
| Milk | 250 ml | 7 to 8 g |
| Curd | 200 g | 7 to 10 g |
| Paneer | 100 g | 18 to 20 g |
| Egg | 1 large | About 6 g |
| Cooked dal | 1 cup | 9 to 12 g |
| Cooked rajma or chana | 1 cup | 12 to 15 g |
| Tofu | 100 g | 8 to 15 g |
| Soya chunks | 25 g dry | 12 to 13 g |
| Roasted chana | 30 g | About 6 g |
| Peanuts | 30 g | 7 to 8 g |
| Cooked chicken | 100 g | 27 to 31 g |
| Cooked fish | 100 g | 20 to 25 g |
These are approximate values. Protein content changes with the variety, brand, recipe, cooking method and serving size. Packaged foods should be checked using the nutrition label, while mixed dishes may require calculation from the quantity of each ingredient. The Indian Food Composition Tables provide nutrient information for commonly consumed foods in India.
Improving Protein Quality in a Vegetarian Diet
Plant-based foods differ in the amounts of essential amino acids they provide. Eating a variety of foods throughout the day helps create a better overall amino-acid balance.
Familiar Indian combinations can make this easier:
- Dal with rice
- Roti with dal and curd
- Khichdi with curd
- Rajma or chana with rice
- Idli or dosa with sambar
- Cereals or millets with pulses and dairy
- Soy, nuts and seeds alongside regular meals
The ICMR-NIN Dietary Guidelines for Indians 2024 recommend obtaining good-quality protein through appropriate food combinations. A vegetarian diet can meet protein needs when it contains sufficient quantities and variety rather than depending mainly on cereals.
Protein Supplements Are Not Necessary for Everyone
Most healthy adults can meet their daily protein requirement through a varied diet. Protein powders may offer convenience, but they are not a replacement for balanced meals and do not provide all the fibre, vitamins, minerals and other nutrients found in whole foods.
The ICMR-NIN Dietary Guidelines for Indians 2024 advise against using protein supplements routinely to build muscle mass. They recommend meeting protein needs through suitable foods and combining adequate dietary protein with resistance exercise.
A doctor or dietitian may recommend a supplement when food intake cannot meet increased nutritional needs. Before using one, discuss the serving size, ingredients, total daily intake and suitability for your health. This is especially important for adolescents, pregnant or breastfeeding women, people taking regular medicines and those with kidney or liver conditions.
When to Get a Personalised Protein Plan
An online protein intake calculator provides general guidance for healthy adults. Consult a doctor or dietitian before changing your protein intake significantly if you:
- Are younger than 18 years
- Are pregnant or breastfeeding
- Have chronic kidney disease, reduced kidney function, kidney stones or receive dialysis
- Have liver disease
- Have diabetes with kidney involvement
- Are underweight or have obesity
- Are an older adult experiencing weakness, poor appetite or muscle loss
- Are recovering from surgery, a serious illness, burns or a major injury
- Have difficulty swallowing or absorbing nutrients
- Follow a highly restricted vegetarian or vegan diet
- Train for competitive sport or endurance events
- Plan to start a high-protein diet or use protein supplements regularly
Protein Intake for People with Kidney Disease
Protein requirements in kidney disease depend on kidney function and treatment. Some people with chronic kidney disease may need a controlled protein intake, while those receiving dialysis may require a different amount. Kidney patients should not use the calculator result to change their diet without consulting their nephrologist or dietitian.

Frequently Asked Questions (FAQs)
How do I calculate my daily protein intake?
A common Indian reference for a healthy adult is body weight in kilograms multiplied by 0.83. For example, a person weighing 60 kg would calculate:
60 × 0.83 = 49.8 grams per day
Activity, age, diet quality, pregnancy and health conditions may change the appropriate amount.
Should I use my current weight or target weight in the calculator?
Use your current weight unless a doctor or dietitian has advised you to use another figure. If you have significant excess weight, are underweight or are following a clinical weight-management plan, a professional assessment may provide a more suitable target than a calculation based only on current weight.
Do men and women need different amounts of protein?
Protein needs are strongly influenced by body weight, activity, muscle mass, age and health. Men may appear to need more on average because they often have a higher body weight or more lean mass, but gender alone does not determine an individual requirement.
Can a vegetarian Indian diet provide enough protein?
Yes. A well-planned vegetarian diet can provide enough protein through dal, beans, chana, rajma, soy, milk, curd, paneer, nuts and seeds. Eating a varied combination of cereals, pulses, dairy or soy throughout the day improves the overall quality of the protein consumed.
Is 100 grams of protein per day too much?
The answer depends on body weight, activity and health. For a person weighing 60 kg, 100 grams equals approximately 1.67 g/kg per day. This falls within commonly used sports nutrition ranges but is much higher than the general Indian adult reference of 0.83 g/kg. It may be unnecessary or unsuitable for someone who is sedentary or has a medical condition.
Does eating more protein automatically build more muscle?
No. Muscle gain requires progressive resistance training, enough total calories, adequate rest and consistent nutrition. Once protein needs are met, consuming more does not guarantee additional muscle growth.
Should protein intake remain the same on rest days?
Many active people maintain a fairly consistent intake because muscle repair continues between training sessions. However, total calories and meal timing may change on rest days. Athletes following a structured programme should use the plan provided by their sports dietitian or coach.
Is it better to eat all my protein in one meal?
Meeting the daily total is important, but spreading protein across meals makes the target easier to reach and provides protein at several points during the day. A dietitian can help determine a practical distribution for your routine.
Do I need protein powder if I exercise?
Not necessarily. Many people can meet their requirements through food. A supplement may be considered when appetite, food preferences, travel or a demanding schedule makes the target difficult to meet, but it should fit within the complete diet rather than being added without calculation.
How often should I use the protein calculator?
Recalculate after a meaningful change in body weight, activity level, training routine or health goal. Seek professional advice if you develop a medical condition, become pregnant, begin intensive athletic training or plan a major dietary change.
