You’ve probably heard that protein matters more as we get older. But the advice can be confusing. Grams? Kilograms? How much is that on a plate?
This guide keeps it simple. We’ll look at what the official U.S. guidelines say, then turn the numbers into everyday foods you already know.
Talk with your doctor before starting any big change in how you eat, especially if you have a health condition or take medicines. And please read the kidney note below.
Why protein matters as we age
Protein helps build and keep up your muscles, bones, skin, and blood. It also helps your body heal wounds and fight illness, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
The newest Dietary Guidelines for Americans (2025–2030) point out something important about older adults. Some of us need fewer calories as we age, but we still need the same or more of certain nutrients, including protein.
That means each meal has more work to do. The National Institute on Aging (NIA) suggests adding foods like seafood, dairy, fortified soy, beans, peas, and lentils to your meals to get enough protein through the day and maintain muscle.
So how much do you need?
The 2025–2030 guidelines set a goal of 1.2 to 1.6 grams of protein per kilogram of body weight per day. They add that you should adjust it based on your own calorie needs.
To find your weight in kilograms, divide your weight in pounds by 2.2. Here’s what the range works out to for a few body weights:
| Your weight | About this in kg | Daily protein goal (1.2 to 1.6 g/kg) |
|---|---|---|
| 130 lb | 59 kg | about 71 to 94 grams |
| 150 lb | 68 kg | about 82 to 109 grams |
| 180 lb | 82 kg | about 98 to 131 grams |
These are general goals for healthy people, not a prescription. If you eat less than you used to, have a health condition, or aren’t sure where in the range you belong, ask your doctor or a registered dietitian.
What that looks like in everyday portions
You don’t need to weigh every bite. MedlinePlus, from the National Library of Medicine, offers an easy rule: one ounce of most protein-rich foods has about 7 grams of protein. Each of these counts as about one ounce:
- 1 ounce of meat, fish, or poultry
- 1 large egg
- ¼ cup of tofu
- ½ cup of cooked beans or lentils
So a 3-ounce piece of chicken or fish has about 21 grams. Two eggs have about 14 grams.
MedlinePlus also lists common serving sizes from the new guidelines, like 2 tablespoons of peanut butter or 1 ounce of nuts or seeds. And dairy, such as milk, yogurt, and cheese, is another good source. The guidelines suggest 3 servings of dairy a day for a 2,000-calorie eating pattern.
Spread it out through the day
The new guidelines say to prioritize protein foods at every meal. Instead of one big steak at dinner, try to have some protein at breakfast, lunch, and dinner.
Breakfast is often the easiest place to start. If your morning meal is mostly toast or cereal, adding an egg, some yogurt, or peanut butter is a small change.
Easy ways to add a little more
- Stir beans or lentils into soup or chili.
- Keep hard-boiled eggs in the fridge for a quick snack.
- Top toast with peanut butter.
- Keep canned fish on hand for fast lunches.
- Bake, broil, roast, or grill instead of deep-frying, as the guidelines suggest.
A tip on salt: many canned foods are high in sodium. Choose “low sodium” or “no salt added” when you can. NIDDK also suggests draining and rinsing canned beans and fish with water to remove extra salt.
An important note about kidney disease
If you have chronic kidney disease (CKD), more protein is not always better. When your body uses protein, it makes waste that your kidneys have to remove. NIDDK says some people with CKD may need to eat moderate amounts of protein so that waste doesn’t build up. But too little protein can cause problems, too. And people on dialysis may need more.
The bottom line: if you have kidney disease, or your doctor has told you to limit protein, don’t increase it without talking to your doctor or a registered dietitian first. The amounts in this article may not be right for you.
Protein works best with movement
Food is only half the story. NIA says strength exercises help slow the loss of muscle and make everyday tasks, like getting up from a chair or carrying groceries, easier. Our post on simple chair exercises for balance is a gentle place to start.
If you’d like more help putting this into practice, Module 2 of our Senior Steps System, Senior Strength Nutrition, has simple daily protein ranges with examples by body weight, meal ideas, a sample day, and a grocery list. It’s $39 on its own, or $89 for all three modules. You can see the programs here.
