How Much Protein Per Day Do You Actually Need?

Ask ten people how much protein per day they should eat and you’ll get ten different answers. One friend swears by 200 grams. A gym trainer says “just eat more chicken.” The label on a protein powder tub suggests you need a scoop after every workout.
The real number is usually much simpler, and it depends mostly on your body weight and what you’re trying to achieve. Let’s sort it out.
The Basic Answer: 0.8 Grams Per Kilogram
The standard recommendation for an average, mostly inactive adult is about 0.8 grams of protein per kilogram of body weight. So if you weigh 70 kg, that’s roughly 56 grams a day.
This number is the minimum needed to avoid deficiency. It’s not necessarily the best amount for someone who trains, is trying to lose fat, or is getting older. That’s where most confusion about how much protein per day comes from: people quote the minimum as if it were the target.
How Much Protein Per Day If You Exercise Regularly?
If you work out three or four times a week, most sports nutrition research points to a higher range: about 1.2 to 2.0 grams per kilogram of body weight.
- Light to moderate exercise (walking, jogging, casual gym): 1.2 to 1.6 g/kg
- Strength training and building muscle: 1.6 to 2.2 g/kg
- Endurance athletes: 1.2 to 1.6 g/kg
For that same 70 kg person lifting weights, the range works out to roughly 112 to 154 grams daily. You don’t need to hit the top of the range. Somewhere in the middle is a sensible place to start.
How Much Protein Per Day for Weight Loss?
When you eat fewer calories, your body can lose muscle along with fat. Eating more protein helps protect the muscle you have, and it also keeps you fuller for longer, which makes a calorie deficit easier to stick to.
For most people trying to lose weight, aiming for 1.4 to 2.0 g/kg is a practical target. Someone who weighs 80 kg would be looking at around 112 to 160 grams a day.
What About Older Adults?
As we age, the body gets less efficient at using protein to maintain muscle. Many nutrition guidelines suggest adults over 60 do better with roughly 1.0 to 1.2 g/kg, and a bit more if they’re active. Spreading it across meals matters more here than piling it all into dinner.
Easy Protein Sources and What They Give You
Numbers on paper are one thing. Here’s what they look like on a plate (approximate values):
- 2 large eggs: about 12 g
- 100 g cooked chicken breast: about 31 g
- 1 cup Greek yogurt: about 17 to 20 g
- 100 g paneer: about 18 g
- 1 cup cooked lentils: about 18 g
- 1 cup milk: about 8 g
- 2 tablespoons peanut butter: about 7 g
- 100 g tofu: about 8 to 12 g
A day with eggs at breakfast, chicken or lentils at lunch, yogurt as a snack, and a protein-rich dinner will get most people close to their target without any powder at all.
Spread It Out Across the Day
Your body doesn’t store protein the way it stores fat, so it helps to spread your intake over three or four meals. Aiming for about 20 to 40 grams per meal works well for most adults. If you currently get 10 grams at breakfast and 80 at dinner, moving some of it earlier is a small change that pays off.
Can You Eat Too Much?
For healthy people, intakes up to about 2 g/kg are considered safe in the research. Going far beyond that rarely gives extra benefit and often just crowds out other foods like fiber-rich carbs and vegetables.
The exception is anyone with kidney disease or another medical condition affecting protein handling. If that’s you, talk to your doctor before raising your intake.
A Simple Way to Work Out Your Number

Take your weight in kilograms and multiply it by the range that fits your situation:
- Mostly sedentary: weight x 0.8
- Regular exercise: weight x 1.2 to 1.6
- Lifting or fat loss: weight x 1.6 to 2.0
Track your meals for three or four days to see where you currently land. Most people are surprised by how far off their guess was, in either direction.
Frequently Asked Questions
Is 100 grams of protein per day too much?
Not for most adults. For someone around 60 to 80 kg who exercises, 100 grams sits comfortably within the normal range.
Do I need protein powder to reach my daily target?
No. Powder is a convenience, not a requirement. Regular food can cover it for most people.
Does protein timing matter after a workout?
The total amount across the day matters far more. Eating some protein within a few hours of training is a good habit, but there’s no need to panic about a 30-minute window.
Can vegetarians reach the right amount of protein per day?
Yes. Lentils, chickpeas, beans, tofu, paneer, yogurt, eggs, and milk make it very doable. Variety across the day covers all essential amino acids.
The Bottom Line
For most people, how much protein per day comes down to a range: about 0.8 g/kg if you’re inactive, and 1.2 to 2.0 g/kg if you exercise or are losing weight. Start with a number that fits your goal, build meals around a protein source, and adjust based on how you feel and perform.
You don’t need perfection. You just need to be in the right neighborhood most days.
