Protein Intake Calculator – Daily Protein Needs (Free, 2026)
Protein Intake Calculator
For healthy adults aged 18 and over
Your Protein Result
Most people guess how much protein they eat, and most guesses are too low. Use the free calculator above to get a daily protein target based on your weight, your goal and your activity level. Then read on to understand the numbers, spread them across your meals and reach them with everyday desi food. If you want the full science first, start with our complete guide on how much protein you really need.
How This Protein Calculator Works
The calculator multiplies your body weight in kilograms by a protein factor, measured in grams per kilogram (g/kg). The factor depends on your goal and how active you are. Lower activity uses the lower end of each range, and hard training uses the higher end.
| Goal | Protein range (g/kg/day) |
|---|---|
| Stay healthy / maintain | 0.8 to 1.4 |
| Lose fat | 1.2 to 1.8 |
| Build muscle | 1.4 to 2.0 |
| Adults 60+ | 1.0 to 1.5 |
You also get a healthy range of 10 percent either side of your target, a per-meal split, and the calories your protein supplies (4 calories per gram). Treat the number as a solid starting point. Your appetite, your results over a few weeks and your doctor's advice can all fine-tune it.
How Much Protein Do You Need Per Day?
The standard recommendation for adults is 0.8 g of protein per kg of body weight. For a 70 kg person, that is 56 g a day. This number is designed to prevent deficiency in the average sedentary adult. It is a floor, not a goal.
Many people benefit from more. If you exercise regularly, are trying to lose fat, or are over 60, your body usually performs better with 1.2 to 2.0 g/kg. Higher protein intakes help repair muscle, keep you full for longer and make it easier to preserve lean mass when your weight changes.
Protein is only one part of your plate, of course. To see how it fits with carbohydrates and fats, read our guide to balancing carbs, protein and fat.
Protein for Weight Loss
When you eat fewer calories than you burn, your body loses fat, but it can also lose muscle. Higher protein is one of the simplest ways to protect that muscle. Protein is also more filling than carbohydrates or fat, and your body uses more energy to digest it, which makes a calorie deficit easier to stick to.
For most people losing fat, 1.2 to 1.8 g/kg works well. A 70 kg person training three or four times a week would land at about 112 g a day. If you are not sure how large your deficit should be, our article on the calorie deficit explained walks you through it step by step.
Eating South Asian food? You do not need to give up roti, rice or curry to eat more protein. You mostly need to add a good protein source to each meal. We cover this in detail in how to lose weight on a desi diet.
Protein for Building Muscle
Muscle grows when you train it and give it enough raw material. Studies pooling many resistance-training trials suggest that the benefit of extra protein levels off at around 1.6 g/kg for most people. Some lifters go up to 2.0 or even 2.2 g/kg, which may help a little in certain cases, but there is no need to chase extreme numbers.
Protein alone will not build muscle. You also need a progressive training routine and enough total calories. If you are new to lifting, begin with our strength training for beginners program, and compare the two styles of exercise in strength training vs cardio.
Want to lose fat and gain muscle together? That is possible for beginners and returning lifters. Higher protein is the foundation of body recomposition, so choose the "Build muscle" or "Lose fat" goal with a high activity level and adjust based on your progress.
Protein for Adults Over 60
As we age, muscles respond less strongly to protein, a change often called anabolic resistance. Older adults also tend to lose muscle faster. That is why the calculator uses 1.0 to 1.5 g/kg for the 60+ goal. Eating protein at every meal, plus some regular strength or resistance exercise, helps protect strength and independence.
Which Body Weight Should You Use?
For most people, current body weight is fine. But if you have a lot of excess weight, the result can look unrealistically high. In that case, many coaches use a goal weight or a healthy-range weight instead.
Not sure where you stand? Check your BMI with our BMI calculator, then get a more complete picture with the body fat percentage calculator. BMI does not separate muscle from fat, so body fat can be a better guide if you lift weights.
How to Spread Protein Through the Day
Total daily protein matters most, but spreading it out makes the target easier to hit. Most adults get a good response from about 0.25 to 0.4 g/kg per meal, which is roughly 20 to 40 g for many people. A typical pattern looks like this:
- Breakfast: 20 to 30 g (eggs, dahi, milk, or paneer)
- Lunch: 30 to 40 g (chicken, fish, or daal with a side of dahi)
- Snack: 10 to 15 g (roasted chana, nuts, or yogurt)
- Dinner: 30 to 40 g (meat, fish, paneer, or legumes)
Many people eat most of their protein at dinner and almost none at breakfast. Moving even 15 to 20 g to the morning is one of the easiest improvements you can make.
Best Desi Protein Sources
You can reach your target with ordinary kitchen food. These values are approximate and vary by brand, recipe and cooking method.
| Food | Serving | Protein (approx.) |
|---|---|---|
| Egg | 1 large | 6 g |
| Chicken breast, cooked | 100 g | 30 g |
| Fish, cooked | 100 g | 20 g |
| Lean mutton or beef, cooked | 100 g | 25 g |
| Paneer | 100 g | 18 g |
| Soya chunks, dry | 30 g | 15 g |
| Daal, cooked | 1 katori (150 g) | 12 g |
| Boiled chana | 1 katori (150 g) | 13 g |
| Dahi (plain yogurt) | 1 katori (150 g) | 5 g |
| Milk | 1 glass (250 ml) | 8 g |
| Roasted chana | 30 g | 6 g |
| Peanuts | 30 g | 8 g |
| Whole wheat roti | 1 medium | 3 g |
| Whey protein | 1 scoop | 20 to 25 g |
Vegetarian? Mix daal, chana, rajma, paneer, dahi, milk, eggs (if you eat them), soya chunks and nuts through the day. Eating a variety of plant proteins helps you cover all the essential amino acids.
Sample Day: 70 kg, Fat Loss, About 115 g Protein
- Breakfast: 3-egg omelette plus a glass of milk, about 26 g
- Lunch: 120 g cooked chicken, 2 rotis and salad, about 42 g
- Snack: 1 katori dahi and 30 g roasted chana, about 11 g
- Dinner: 100 g fish, 1 katori daal and 2 rotis, about 38 g
That comes to roughly 117 g, which fits a 70 kg person with a fat-loss goal. Swap in paneer, soya chunks or rajma if you prefer a vegetarian version.
Common Protein Mistakes
- Eating almost no protein at breakfast. A tea and biscuit start leaves you hungry and behind on your target.
- Relying only on shakes. Whole foods bring fiber, vitamins and minerals that a scoop of powder does not.
- Ignoring total calories. Extra protein does not cancel out an overall calorie surplus if your goal is fat loss.
- Chasing extreme numbers. Going far beyond about 2.2 g/kg rarely adds benefit and can crowd out other nutrients.
- Skipping strength training. Protein helps you keep or build muscle, but exercise is the signal that tells your body to do it.

Frequently Asked Questions (FAQs)
Q1: How much protein do I need per day?
Answer: The minimum recommended intake for most adults is 0.8 grams of protein per kilogram of body weight. That prevents deficiency, but many active people, people losing weight and adults over 60 do better with 1.2 to 2.0 grams per kilogram. Use the calculator above to get a number based on your weight, goal and activity level.
Q2: How much protein do I need to lose weight?
Answer: Most people losing fat do well with about 1.2 to 1.8 grams of protein per kilogram of body weight per day. Higher protein helps you stay full and protects muscle while you eat fewer calories. A 70 kg person would aim for roughly 85 to 125 grams daily.
Q3: How much protein do I need to build muscle?
Answer: Research suggests muscle growth is well supported at about 1.6 grams of protein per kilogram of body weight per day, with some people using up to 2.0 or 2.2 grams. Combine this with resistance training and enough total calories for the best results.
Q4: Can I get enough protein on a vegetarian diet?
Answer: Yes. Daal, chana, rajma, paneer, dahi, milk, eggs, soya chunks and nuts can all contribute. Vegetarians may need to plan a little more, and combining different plant proteins through the day helps cover all essential amino acids.
Q5: Is too much protein bad for your kidneys?
Answer: In healthy people, intakes in the ranges used by this calculator have not been shown to damage the kidneys. However, people with kidney disease or reduced kidney function should follow their doctor's advice and not raise protein on their own.
Q6: Do I need protein powder?
Answer: No. Protein powder is a convenience, not a requirement. If you can reach your daily target with eggs, chicken, fish, daal, dairy and other whole foods, you do not need a supplement.
Q7: Does protein timing matter?
Answer: Your total daily intake matters most. Spreading protein across three to five meals, with roughly 20 to 40 grams each, is a practical way to hit your target and support muscle repair, but you do not need to eat protein at an exact minute after a workout.
