How Much Protein Is Enough?

by Dr. Stacy Sims

It’s a question I’m asked by women a lot: How much protein should I consume every day? And while the detailed answer will always depend on your age, your activity level, your menstrual cycle status, and plenty more, there are a few simple guidelines that can help get you on the right side of the protein tracks.

Protein RDA

The recommended daily allowance (RDA) for protein is about 1 gram per kilogram (kg) of body weight, or roughly 0.45 grams per pound (lb). This amount is just about sufficient for sedentary individuals, but it can differ based on age, sex, and activity levels. For active women, sports scientists suggest aiming for 1 gram of protein per pound of body weight.

Research has shown that for women aged 20-35, optimal daily protein intake is 1.6-2.2g/kg/day (0.7g-1g/lb/day), while older women, especially those in perimenopause and menopause, may need slightly higher amounts. This 2023 study recommends that daily protein intake should fall within 1.4-2.2g/kg/day (0.6g-1g/lb/day), with protein distributed evenly across meals every 3-4 hours. This helps maintain lean body mass and supports body composition and weight loss. Studies have also shown that overall daily protein needs are higher during the luteal phase of the menstrual cycle.

You Didn't Lose Fitness, You Lost Fuel

If you grew up in the ‘80s and ‘90s, you were handed two contradictory rulebooks. First, fat was the enemy. Then, almost overnight, fat was fine and carbohydrate was the problem. Neither was built on good science, and neither was built with active women in mind, yet both stuck. I see the impact everywhere: women who are highly active, lift heavy, know what they’re doing—and still hesitate whe...

What My Grandmothers Taught Me About Aging Well

My great-grandmother lived to 105. One of my grandmothers made it to 106. The other was 97 when she died. While the numbers on their own don’t tell you much, I can tell you what it actually looked like. All three lived independently. All three had their faculties—sharp, opinionated, entirely themselves right to the end. You’d walk into my great-grandmother’s house and before your coat was off...

How to Think Like an Athlete

I was giving a keynote earlier this year to a room full of active women, and asked them to raise their hand if they considered themselves an athlete. I’d say maybe less than a quarter of hands went up. The rest looked around, unsure. The scientist in me had been curious about this for a while, so it wasn’t entirely surprising, but it still told me something. I know for a fact there were badas...
