How Much Protein Do You Need After 55?

Protein becomes increasingly important as we get older—but that doesn’t mean you need a steak, a protein shake, or an enormous amount of protein at every meal.

A well-planned plant-based diet can provide plenty of protein after 55. The bigger question is how much you actually need, where to get it, and how to spread it throughout your day.

Why Protein Matters More After 55

As we age, maintaining muscle becomes increasingly important for strength, mobility, balance, and independence. Getting enough protein—along with regular resistance exercise—helps support and preserve that muscle.

The goal isn’t simply to eat “more protein.” It’s to get enough high-quality protein from a variety of foods throughout the day.

How Much Protein Do You Need After 55?

The standard Recommended Dietary Allowance (RDA) for adults is 0.8 grams of protein per kilogram of body weight per day. But research on healthy aging suggests many older adults may benefit from somewhat more—often around 1.0 to 1.2 grams per kilogram per day.

Your ideal amount depends on your body size, activity level, overall diet, and health. The important point: you can reach these amounts with plant foods.

Best Plant-Based Protein Sources

Beans, lentils, tofu, tempeh, edamame, peas, whole grains, nuts, seeds, and soy foods can all contribute meaningful amounts of protein. You don’t need one “perfect” protein food—the variety across your day matters.

Plant-Based Protein at a Glance

FoodServingApprox. Protein
Lentils1 cup cooked18 g
Edamame1 cup cooked18 g
Tempeh½ cup15–16 g
Black beans1 cup cooked15 g
Tofu½ cup10–12 g
Soy milk1 cup7–9 g

How to Spread Protein Throughout Your Day

Instead of trying to get most of your protein at dinner, spread it across breakfast, lunch, dinner, and snacks. Adding tofu or soy milk at breakfast, beans or lentils at lunch, and tempeh, edamame, or another soy food at dinner can make the day add up without much effort.

Do You Need Protein Powder?

For most people, protein powder isn’t necessary. Whole plant foods can provide plenty of protein while also delivering fiber, vitamins, minerals, and other beneficial compounds.

That said, protein powder can be convenient when appetite is low, meals are rushed, or someone has higher protein needs. Think of it as a tool—not a requirement.

Protein and Strength Training Work Together

Protein is only part of the healthy-aging equation. Your muscles also need a reason to stay strong. Regular resistance exercise—weights, resistance bands, or body-weight movements—works together with adequate protein to help maintain muscle and strength as you age.

Walking is excellent for overall health, but adding some form of strength training becomes increasingly important after 55.

A Simple Plant-Based Protein Day

A protein-rich day doesn’t have to revolve around counting grams. Oatmeal with soy milk and seeds, a lentil or bean-based lunch, and tofu, tempeh, or edamame at dinner can provide substantial protein while also delivering fiber and a wide range of nutrients.

Example of a Protein-Rich Plant-Based Day

Breakfast

Oatmeal with soy milk, chia or flax, berries and walnuts

Approx. 18–22g protein

Lunch

Lentil and quinoa bowl with vegetables

Approx. 25–30g protein

Dinner

Tofu or tempeh with edamame, vegetables and potatoes

Approx. 30–35g protein

Snack

Fruit with a handful of nuts or roasted edamame

Approx. 6–12g protein

The Bottom Line

Protein matters as we age, but getting enough doesn’t require animal foods or making every meal revolve around protein.

A varied plant-based diet built around beans, lentils, tofu, tempeh, edamame, whole grains, nuts and seeds can provide substantial protein while also delivering fiber and other nutrients that support healthy aging.

Pair those foods with regular strength training, stay active, and focus on the overall quality of your diet rather than obsessing over a single number.
