How much protein does your family need?

Adults need at least 0.8 grams of protein per kilogram of body weight a day, children 13 to 34 grams depending on age, and teens who play sports about 1.5 grams per kilogram. Add everyone at your table to see each person’s number, how to spread it over the day, and what dinner needs to bring.

Protein each day

  • You, 38

    55 g a day

    About 18 g at each meal

    The recommended amount at age 38 is 0.8 grams per kilogram of body weight a day. That is a minimum, not a maximum.

  • Jake, 15, plays a sport

    About 85 g a day

    Range: 70 to 115 g

    About 17 g 4 to 5 times a day

    Young athletes need about 1.5 grams per kilogram a day (the sports range is 1.2 to 2.0), spread over meals and snacks.

  • Lily, 8

    24 g a day

    About 8 g across meals and snacks

    The recommended amount at age 8 is 0.95 grams per kilogram of body weight a day.

Dinner for everyone: about 54 g of protein

That’s a third of the day, or roughly ½ lb of boneless chicken. Beans, cheese, milk and a yogurt sauce count too.

With Plus, save these goals to your family profile and every recipe shows how big to make each person’s plate.

Protein needs by age

These are the U.S. recommended amounts for healthy people, from the National Academies. The gram figures use a typical body weight for each age; the per-kilogram column gives a personal number.

The recommended amount covers the needs of nearly everyone, so it works as a floor rather than a goal for adults. Teens and adults in hard training, adults over 65 and people on GLP-1 medications are advised to aim higher.

Getting there without counting every gram

Breakfast is where most families fall short

Plenty of households eat most of their protein at dinner and very little in the morning. An egg, a cup of Greek yogurt or a glass of milk with breakfast evens the day out without a bigger dinner.

Spread it out

Your body uses protein better in several helpings than in one huge one. For most adults that means 25 to 40 grams at each meal, and for teen athletes a helping every 3 to 4 hours, including after practice.

Food before powder

Chicken, eggs, dairy, beans and fish bring iron, calcium and fiber along with the protein. Powders are supplements that the FDA doesn’t review before they’re sold, so keep them for busy days, not every day.

Most kids are already covered

A child’s needs are small. Two cups of milk and an egg cover a whole day for a 6-year-old. If your kids eat a varied diet, there is no need to count their grams.

Turn the numbers into dinner

Type what’s in your fridge into the high-protein recipe generator and get a family dinner with at least 30 grams per adult serving, built from real food. Feeding someone who trains? Our guide to feeding a teen athlete covers practice nights, game days and the 9 p.m. second dinner.

With Plus, save each person’s goal to your family profile. Every recipe then ends with a plate for each of them: how much to serve, and the protein it gives.

Protein questions parents ask

How much protein do I need a day?

The recommended amount for adults is 0.8 grams per kilogram of body weight, or about 0.36 grams per pound. That is 54 grams for a 150-pound adult. It is a minimum: people who train hard need 1.2 to 2.0 grams per kilogram, and adults over 65 are advised to aim for 1.0 to 1.2.

How much protein does a child need?

The recommended amounts are 13 grams a day for ages 1 to 3, 19 grams for ages 4 to 8 and 34 grams for ages 9 to 13. A cup of milk has 8 grams and an egg about 6, so most kids reach their number without anyone planning for it.

How much protein does a teenage athlete need?

About 1.5 grams per kilogram of body weight a day, within a range of 1.2 to 2.0, spread over 4 or 5 meals and snacks. For a 130-pound teen that is roughly 90 grams a day, or about 18 grams each time they eat. Read our guide to feeding a teen athlete for what that looks like on a practice night.

Can you eat too much protein?

For healthy people, intakes up to about 2 grams per kilogram a day are generally considered safe, and studies find little extra muscle benefit above about 1.6. Very high-protein diets can crowd out fiber, fruit and vegetables. People with kidney disease should follow their doctor’s advice on protein.

Do I need protein powder?

Usually not. Food covers most people’s needs, and powders are dietary supplements that are not reviewed by the FDA before they are sold. For children and teens, the American Academy of Pediatrics says nutrition needs are best met with food. A powder can help an adult on a busy day or on a GLP-1 medication when appetite is low.

Why does the calculator ask for weight?

Protein needs are set per kilogram of body weight, so weight gives a personal number. Leave it blank and the calculator uses the recommended amount for that age instead.
