how much protein do I need per day
If you are working out, trying to lose weight or building muscle, you have probably wondered: how much protein do I need per day? Protein is one of the most important nutrients for muscle repair, recovery and maintaining lean body mass, but your ideal intake depends on your body weight, activity level and fitness goal.
For a healthy adult, the basic protein requirement is around 0.8 g per kg of body weight per day. However, people who exercise regularly, want to build muscle or are trying to lose fat may need more.
There is no single protein target that works for everyone.
A simple way to estimate your requirement is:
Body weight (kg) × protein target (g/kg) = daily protein requirement
For example, if you weigh 60 kg and choose a target of 1.4 g/kg:
60 × 1.4 = 84 grams of protein per day
Your ideal intake can vary depending on your goal.
| Goal | Protein per kg of body weight |
|---|---|
| Basic requirement | 0.8–1.0 g/kg |
| General fitness | 1.0–1.2 g/kg |
| Weight loss | 1.2–1.6 g/kg |
| Muscle gain | 1.4–1.6 g/kg |
| Regular strength training | Around 1.6 g/kg |
These are practical ranges rather than strict rules. Your age, training intensity, calorie intake and overall health can also influence your protein needs.
You can calculate your estimated protein intake per day using your body weight.
Formula:
Body weight × protein requirement = daily protein target
For example:
For someone who regularly performs resistance training, using approximately 1.6 g/kg can be a useful target. Research has found that increasing protein intake during resistance training can support gains in lean body mass, with benefits generally leveling off around 1.6 g/kg/day.
| Body Weight | 1.0 g/kg | 1.2 g/kg | 1.4 g/kg | 1.6 g/kg |
|---|---|---|---|---|
| 50 kg | 50 g | 60 g | 70 g | 80 g |
| 55 kg | 55 g | 66 g | 77 g | 88 g |
| 60 kg | 60 g | 72 g | 84 g | 96 g |
| 65 kg | 65 g | 78 g | 91 g | 104 g |
| 70 kg | 70 g | 84 g | 98 g | 112 g |
| 75 kg | 75 g | 90 g | 105 g | 120 g |
| 80 kg | 80 g | 96 g | 112 g | 128 g |
| 90 kg | 90 g | 108 g | 126 g | 144 g |
| 100 kg | 100 g | 120 g | 140 g | 160 g |
If your goal is muscle gain, protein should be combined with resistance training and adequate overall nutrition.
Research involving resistance-trained adults suggests that protein intake around 1.6 g/kg/day is sufficient for maximizing most of the additional muscle-building benefit associated with increased protein intake. Going substantially above this does not automatically mean more muscle.
For example, a 70 kg person could use:
70 × 1.6 = 112 g protein per day
This does not mean you need to consume 112 g of protein from supplements. Your daily meals can provide a large portion of your requirement.
Protein becomes especially important when you are trying to lose body fat.
During a calorie deficit, maintaining adequate protein intake along with resistance training can help support lean muscle mass. Research in adults with overweight or obesity has found that higher protein intake can help preserve muscle during weight loss.
A practical range for an active person trying to lose fat is approximately:
1.2–1.6 g protein per kg body weight per day
For example, if you weigh 65 kg:
65 × 1.4 = 91 g protein per day
However, protein alone does not cause fat loss. A sustainable calorie deficit, regular exercise, adequate sleep and a balanced diet are also important.
Women do not automatically need a completely different protein formula.
Protein requirements depend largely on:
For example, a woman weighing 60 kg who regularly strength trains could use a target of approximately 1.4–1.6 g/kg depending on her goals.
That would equal roughly 84–96 g of protein per day.
The same basic calculation can be used for men.
For example, a 75 kg man who strength trains could use:
75 × 1.6 = 120 g protein per day
Larger body size does not necessarily mean you need extremely high protein intake. More protein is not automatically better once your nutritional requirements are being met.
Indian diets can provide plenty of protein without relying entirely on supplements.
Combining different protein sources throughout the day can make it easier to reach your daily target.
No. Whey protein is a supplement, not a necessity.
If you can comfortably meet your daily protein requirement through food, you do not need whey protein simply because you work out.
Whey can be useful when you have difficulty getting enough protein from normal meals or want a convenient post-workout option.
For example, a person who needs 100 g of protein per day could get it from a combination of eggs, dairy, paneer, chicken, fish, soy, dal and other foods.
More protein is not always better.
For healthy adults, higher protein intake may be appropriate depending on training and dietary goals, but extremely high intakes are unnecessary for most people.
If you have kidney disease, liver disease or another medical condition, speak with a qualified healthcare professional before significantly increasing your protein intake.
Your diet should also contain carbohydrates, healthy fats, vegetables, fruits and adequate fibre rather than focusing exclusively on protein.
Instead of eating almost all your protein in one meal, it can be practical to distribute it across breakfast, lunch, snacks and dinner.
For example, someone targeting 100 g per day could aim for approximately:
Research on protein distribution suggests that spreading protein across multiple meals can be a useful strategy for supporting muscle protein synthesis, particularly when combined with resistance training.
You don’t need complicated recipes to increase your protein intake.
Some easy options include:
Breakfast: Eggs, Greek yogurt, paneer, milk or besan chilla
Lunch: Dal, rajma, chicken, fish, paneer or tofu with rice/roti and vegetables
Snack: Greek yogurt, roasted chana, milk, boiled eggs or a protein shake
Dinner: Chicken, fish, tofu, paneer, soy chunks or dal
The best protein source is one that fits your dietary preferences, budget and overall nutritional needs.
If you’re still wondering how much protein do I need per day, start with your body weight and fitness goal.
For basic nutritional needs, approximately 0.8–1.0 g/kg/day is a useful reference.
For active people, a target around 1.2–1.6 g/kg/day may be more appropriate depending on the goal.
For resistance training and muscle gain, approximately 1.6 g/kg/day is a strong evidence-based target for many healthy adults.
The easiest calculation is:
Remember that protein is only one part of a healthy fitness plan. Your total calories, workout routine, sleep, hydration and overall diet all matter.
A healthy adult’s basic requirement is around 0.8 g/kg of body weight per day. Active people may need approximately 1.2–1.6 g/kg depending on their fitness goals and training.
For people doing resistance training, around 1.4–1.6 g/kg/day is a practical target. Research suggests that benefits generally plateau around 1.6 g/kg/day for muscle gain.
Many active adults can consider approximately 1.2–1.6 g/kg/day while losing weight, particularly when resistance training is part of the routine.
Multiply your body weight in kilograms by your chosen protein target in grams per kilogram. For example, 60 kg × 1.4 g/kg equals 84 g of protein per day.
Depending on your goal, approximately 60–96 g per day can cover a range from basic needs to regular strength training.
Not necessarily. Protein needs are influenced by body weight, activity, age and fitness goals rather than simply being male or female.
Yes. Paneer, curd, milk, soy, tofu, dal, rajma, chana, sattu, nuts and seeds can all contribute to your daily protein intake.
No. Whey protein can make it easier to reach your target, but muscle gain does not require protein supplements if your regular diet provides adequate protein.
