Protein is the nutrient everyone talks about and few people count. So how much do you actually need? The answer depends on your body weight, your activity level and your goal. This guide gives you simple numbers, a quick way to calculate your target and easy ways to reach it with real food.

The basic numbers

The recommended dietary allowance (RDA) for adults is 0.8 grams of protein per kilogram of body weight per day. That is the minimum to prevent deficiency, not necessarily the best amount for people who train. Sports nutrition guidelines commonly suggest around 1.2 to 2.0 grams per kilogram for active people, and some older adults benefit from higher intakes too.

Goal	Grams per kg per day	Grams per pound per day
General health (RDA)	0.8	0.36
Active or regular exercise	1.2–1.6	0.55–0.73
Building muscle	1.6–2.0	0.73–0.9
Weight loss while keeping muscle	1.6–2.0	0.73–0.9

Quick calculator by body weight

Body weight	0.8 g/kg	1.2 g/kg	1.6 g/kg	2.0 g/kg
60 kg (132 lb)	48 g	72 g	96 g	120 g
70 kg (154 lb)	56 g	84 g	112 g	140 g
80 kg (176 lb)	64 g	96 g	128 g	160 g
90 kg (198 lb)	72 g	108 g	144 g	180 g

To calculate your own number: multiply your weight in kilograms by the grams per kilogram you chose. If you know your weight in pounds, divide by 2.2 to get kilograms.

Protein in common foods (approximate)

Food	Serving	Protein
Chicken breast, cooked	100 g (3.5 oz)	About 31 g
Salmon, cooked	100 g (3.5 oz)	About 22–25 g
Eggs	1 large	About 6 g
Greek yogurt, plain	3/4 cup (170 g)	About 15–17 g
Cottage cheese	1/2 cup	About 12–14 g
Lentils, cooked	1 cup	About 18 g
Tofu, firm	100 g	About 8–10 g
Whey protein powder	1 scoop	About 20–25 g

Values vary by brand and preparation, so check labels for accuracy.

How to reach your protein target

1. Spread it out. Aim for about 20 to 40 grams at each main meal.
2. Build meals around protein. Start with eggs, yogurt, chicken, fish, beans or tofu.
3. Plan snacks. Greek yogurt, cottage cheese, jerky or a protein bar help fill gaps.
4. Use powder if needed. See our guide to protein powder.
5. Prep ahead. Our meal prep ideas make high-protein meals easy.

Can you eat too much protein?

For healthy adults, intakes at the upper end of the ranges above are generally considered safe. People with kidney disease or other medical conditions may need to limit protein and should follow their doctor’s advice. If you take supplements or follow a restrictive diet, speak with a registered dietitian.

Protein tools to make it easier

If you struggle to hit your number with food alone, a simple shaker and a basic protein powder can help. These are optional.

Whey protein powder

A convenient way to add 20 to 25 grams of protein to your day. See our full guide before you choose.

Digital food scale

Weighing portions is the easiest way to know how much protein you are eating.

Sample high-protein days

Meal	Approx. 100 g day	Approx. 140 g day
Breakfast	Greek yogurt with berries and nuts (20 g)	3-egg omelet with spinach and a side of yogurt (35 g)
Lunch	Chicken and rice bowl (35 g)	Large chicken salad with chickpeas (45 g)
Snack	Cottage cheese with fruit (14 g)	Protein shake and a banana (25 g)
Dinner	Salmon, potatoes and vegetables (30 g)	Lean beef or tofu stir-fry with rice (40 g)

Values are rough and vary with portion size and brand.

Protein for vegetarians and vegans

You can reach your target with tofu, tempeh, lentils, beans, edamame, seitan, dairy or eggs (if you eat them) and soy or pea protein powders. Combining different plant proteins through the day helps cover all essential amino acids.

Protein as you get older

Many older adults benefit from a higher protein intake to help preserve muscle. Guidelines often suggest around 1.0 to 1.2 grams per kilogram or more, spread across meals and combined with strength training. Check with your doctor, especially if you have kidney issues.

Common protein mistakes

• Eating most of your protein at dinner and very little at breakfast.
• Relying on bars and shakes instead of whole foods.
• Guessing portions instead of checking a label or weighing once.
• Forgetting that protein needs depend on activity and age.

Frequently asked questions

Do I need more protein to lose weight?

Higher protein intake can help you feel full and preserve muscle while you lose fat. Aim for the upper half of the range if you are strength training.

Is plant protein as good as animal protein?

Plant proteins can meet your needs if you eat a variety and enough total protein. You may need slightly more of some sources.

Does protein timing matter?

Total daily protein matters most. Spreading it across meals is a good habit, but there is no need to panic about an exact post-workout window.
