Protein is essential for building and repairing muscle, supporting immunity, making enzymes and hormones, and keeping you full between meals. Yet the question “how much protein do I need?” has different answers depending on your age, body weight, and how active you are. This guide explains the standard guidelines, what they mean in everyday food, and when you may need more or less.
The Basic Guideline: 0.8 g per Kilogram
The Recommended Dietary Allowance for healthy adults is about 0.8 grams of protein per kilogram of body weight per day. For a 60 kg adult, that is roughly 48 grams. This figure is designed to prevent deficiency in most healthy people, not to optimise muscle health, recovery, or ageing. Many nutrition researchers consider it a minimum rather than a target.
Protein Needs by Situation
| Group | Approximate Intake | Why It Differs |
|---|---|---|
| Sedentary adults | 0.8 g per kg | Meets basic needs |
| Regular exercisers | 1.2 to 1.6 g per kg | Supports repair of muscle fibres |
| Strength training or muscle building | 1.6 to 2.2 g per kg | Higher demand for muscle protein synthesis |
| Adults over 65 | About 1.0 to 1.2 g per kg | Muscle loss with age makes higher intake useful |
| Pregnancy and breastfeeding | Higher than standard | Supports the growth of the baby and milk production |
For example, a 70 kg adult who lifts weights three times a week would aim for roughly 112 to 154 grams of protein per day. A 70 kg sedentary adult needs closer to 56 grams.
What Protein Looks Like on Your Plate
Most people do not weigh food, so it helps to know rough portions. Each of these provides about 10 to 15 grams of protein:
- One cup of cooked dal or rajma
- Two eggs
- One cup of plain Greek yogurt
- 100 grams of paneer or tofu
- A palm-sized portion of chicken, fish, or lean meat
- One cup of milk combined with a handful of nuts
Spread Protein Across the Day
Research suggests the body uses protein most effectively when it is spread across meals, with roughly 20 to 40 grams per sitting for most adults. Eating very little protein at breakfast and lunch, then a large amount at dinner, is less effective for muscle maintenance than a steady pattern. A simple rule is to include a protein source at every meal.
Signs You May Not Be Getting Enough
- Slow wound healing or frequent infections
- Persistent tiredness or feeling weak
- Loss of muscle strength or shape
- Thinning hair or brittle nails
These symptoms have many possible causes, including low iron, low vitamin D, thyroid issues, and poor sleep. If they persist, see a doctor rather than assuming protein is the only problem.
When to Be Cautious
Very high protein intake is not automatically better. People with chronic kidney disease, certain liver conditions, or gout may need to limit protein, and the right amount depends on their medical team’s assessment. Anyone with an existing condition should discuss targets with a doctor or renal dietitian before changing their diet significantly.
Practical Takeaways
Most people can meet their needs with regular meals built around a protein food, such as dal at lunch, eggs or paneer at breakfast, and fish, chicken, tofu, or legumes at dinner. Track intake for a few days to see where you stand, then adjust. The goal is consistency, not perfection.
