How Much Protein Do Women Over 40 Need?

There isn't one protein target that applies to every woman over 40.

If you’re wondering how much protein do women over 40 need, the answer depends on body weight, activity level, training, and goals—but there are useful ranges we can start with.

For healthy older adults, expert groups commonly recommend around 1.0–1.2 grams of protein per kilogram of body weight per day, with 1.2 g/kg or more often recommended for people who are physically active.

For someone who strength trains and wants to build or maintain muscle, a practical target can be higher. As we discussed in our broader protein article, around 1.6 g/kg—or roughly 0.7 grams per pound of body weight per day—is a useful target for people doing resistance training.

For a 150-pound woman, that works out to approximately 105 grams of protein per day.

That doesn't mean 104 grams is a failure and 106 grams is a success.

It gives you a useful target to work toward.

Why Protein Becomes More Important as You Age

Muscle isn't something we should only care about for appearance.

Preserving muscle and strength becomes increasingly important as we age. Research on older adults has found that adequate protein combined with resistance training can support lean mass, while resistance training itself remains one of our most important tools for maintaining strength and function.

This is one reason I emphasize protein with my clients.

Protein supplies the amino acids your body uses in the processes involved in building and repairing tissue. I also like it from a practical nutrition standpoint because higher-protein foods can make it easier to build meals that support your body-composition goals.

But here's the part I don't want you to overcomplicate:

You don't need to become obsessed with protein.

You need a reasonable target you can consistently hit.

Make Your Protein Target Realistic

One of the biggest problems I see isn't understanding that protein is important.

It's actually eating enough of it consistently.

A simple place to start is looking at the meals you already eat and asking: where is my protein coming from?

Choose protein sources you actually enjoy. If you're struggling to reach your target through meals, a protein shake can be a convenient option. Spreading your protein across your meals can also make a larger daily target feel much more manageable. These are strategies I use with clients who have difficulty getting enough protein into their day.

You don't need a perfect meal plan.

And you certainly don't need to panic about getting protein within some tiny post-workout window. For the average person, consistently getting your overall nutrition right matters much more than obsessing over timing.

The Bottom Line

So, how much protein do women over 40 need?

There isn't one number for everyone, but if you're active and strength training, around 0.7 grams per pound of body weight per day is a practical target.

If you weigh 150 pounds, that's roughly 105 grams.

Start there. Build protein into foods you already enjoy. Track it for a while and see what your normal intake actually looks like.

The goal isn't to eat as much protein as possible.

It's to eat enough to support the work you're doing in the gym—and to find an approach you can actually maintain.
