Protein for men over 40: how much, how often, and how to actually hit it
Short answer
Most men over 40 do well on 0.8 to 1.2 grams of protein per pound of goal bodyweight a day, split across three or four meals of roughly 30 to 40 grams each. Lift three times a week. Protein supports the training. It does not replace it.

How much protein does a man over 40 need in a day?
Start with the weight you are aiming for, not the one on the scale today. A man at 230 pounds who wants to be 190 works from 190.
My range is 0.8 to 1.2 grams per pound of that goal weight. For 190 pounds, that is 152 to 228 grams a day. If you're training hard, three or more sessions a week and working to build or hold muscle, push toward the 0.8 to 1.2 range as your real target. If your training is lighter, or you're just getting started, stay in the lower half until that changes.
The research on people who train points to a slightly lower band. A 2018 review found at least 1.6 grams per kilogram a day (about 0.7 per pound) is a sound minimum for building muscle, and it noted intakes up to 2.2 grams per kilogram (about 1.0 per pound) in the literature. Above that there is little evidence of extra benefit. So the top of my range is a ceiling you rarely need, not a target you must reach.
If you have kidney disease or a doctor has told you to limit protein, check with them before raising your intake.
How much should I eat at each meal?
Aim for about 0.18 grams per pound of goal bodyweight at each of four meals. For a 190 pound goal that is around 34 grams. In practice, 30 to 40 grams at each main meal and a smaller amount at a snack gets most men there.
The same review concluded that spreading protein across at least four meals beats loading it into one. I said the same in episode 146: put a protein source in every meal and snack.
What are the easiest protein sources for a busy dad?
Eggs, Greek yogurt, chicken, canned fish, lean beef, cottage cheese and whey. For plant-based eaters, tofu, tempeh, lentils, beans and quinoa, with more variety across the day.
Watch the foods that sound like protein and are mostly fat. In episode 146 I tell the story of a client eating a Costco bag of nuts, a handful at a time, on the road. Nuts are good food. A third of that bag was most of his fat for the day.
Do I need protein powder?
No. Powder is convenient when you are short of time, and a shake can cover a meal you would otherwise skip. Whole food first, powder to fill gaps.
Will more protein make me bulky?
No. In episode 113 I say it directly: protein supplies the building blocks, and training is the signal that tells the body to grow. Eating protein without lifting does not build muscle.
What should I do first?
- Write down your goal weight.
- Multiply by 0.8 and by 1.2 to get your range, and pick a number in the lower half unless you're training hard.
- Divide it by four to get a per-meal target.
- Track your protein for seven days, no other changes. Most men find their biggest gap is at breakfast.
- Fix breakfast first.
Questions men ask
- Should I count protein from my goal weight or my current weight?
- Goal weight. It keeps the target from ballooning when you are carrying extra fat.
- Can I get enough protein on a plant-based diet?
- Yes, with planning. It takes larger portions and more variety, and a plant-based shake can help.
- Is 30 grams per meal a hard limit?
- No. The review found no fixed cap, and larger doses are still used by the body. Even spreading matters more than any single number.
- How long until I notice a difference?
- Protein alone changes little. Combined with three lifting sessions a week, most men feel stronger within a few weeks.
