Answer: Most active men over 40 do well with a palm-sized portion of protein at each of three or four meals. The official RDA is 0.8 grams per kilogram of body weight a day, and sports nutrition groups such as the American College of Sports Medicine suggest about 1.2 to 2.0 grams per kilogram for active adults. Men with kidney disease should ask a doctor before eating more.
- The RDA of 0.8 g per kg is a minimum, not a target for men who train.
- Active men often aim for about 1.2 to 1.6 g per kg, spread over meals.
- Breakfast is where most men fall short.
- Kidney disease means talking to a doctor before raising protein.
Why protein matters more after 40
From middle age, men slowly lose muscle and strength if they do nothing about it. Muscle also becomes a little less responsive to the signal from a meal, which researchers sometimes call anabolic resistance. Put simply, a 50-year-old often needs a slightly larger dose of protein at a meal than a 25-year-old to get the same muscle-building response.
Protein is not only about the gym. It supplies the building blocks for muscle repair, enzymes and immune cells, and it keeps you full longer, which helps if you are trying to trim your waist. Pairing enough protein with regular lifting is one of the most reliable ways to hold on to strength with age. Our safe starting plan for strength training covers the other half of that equation.
How much: the numbers in plain English
The Recommended Dietary Allowance set by the National Academies is 0.8 grams of protein per kilogram of body weight a day. That is the amount needed to prevent deficiency in most healthy adults, not the amount that best supports training. A joint position statement from the American College of Sports Medicine and dietitian groups suggests about 1.2 to 2.0 grams per kilogram for active adults.
Here is how that works for a man who weighs 90 kilograms, about 200 pounds:
- At the RDA: about 72 grams a day.
- At 1.4 grams per kilogram: about 126 grams a day.
- Split over four meals: roughly 30 grams each.
Most active men land comfortably in the middle of the range. Going far above it rarely adds benefit and crowds out vegetables, fiber and whole grains.
Spreading protein across the day
Many men eat almost no protein at breakfast, a little at lunch and a large portion at dinner. The total can look fine while the morning and midday meals do very little for muscle. A more even spread, with roughly 25 to 40 grams at each main meal, is a simple goal that many sports dietitians use for older lifters.
Practical ways to even it out:
- Add eggs, Greek yogurt or cottage cheese to breakfast.
- Build lunch around chicken, tuna, beans or tofu instead of a sandwich that is mostly bread.
- Keep a high-protein snack after training, such as milk or yogurt.
The table below gives rough figures from USDA food data so you can estimate without weighing everything. Labels on packaged foods will give you exact numbers.
| Food (typical serving) | Approximate protein |
|---|---|
| 3 oz cooked chicken breast | About 26 g |
| 1 cup plain Greek yogurt | About 20 to 23 g |
| 3 oz canned tuna | About 20 g |
| 1 cup cooked lentils | About 18 g |
| 1 cup milk | About 8 g |
| 1 large egg | About 6 g |
A worked day for a 52-year-old who lifts twice a week
Picture a 52-year-old man, about 85 kilograms, who lifts on Tuesdays and Saturdays and walks most days. His usual day was toast and coffee, a ham sandwich, and a large steak dinner. When we would add it up, he reached roughly 75 grams, with almost all of it in the evening.
The changes we would suggest are small. Two eggs and a cup of Greek yogurt at breakfast adds around 30 grams. Swapping the sandwich for a chicken and bean bowl lifts lunch to about 35 grams. A glass of milk after training and a normal-sized dinner portion bring the day to about 120 grams, roughly 1.4 grams per kilogram, without protein shakes. He would then track strength and energy for 8 weeks rather than judge after a few days.
Limits: kidneys, powders and what protein will not do
Higher protein intakes appear safe for healthy kidneys, but men with chronic kidney disease, or diabetes with kidney changes, should ask a doctor or dietitian before eating more. The same goes for anyone told to limit protein for a medical reason.
Protein powders are dietary supplements, not drugs, so their quality varies. The NIH ODS: Dietary Supplements, What You Need to Know fact sheet explains that supplements are not approved for safety and effectiveness before sale. Look for third-party testing seals if you use one.
Protein also has limits. It supports muscle when you train, but it does not raise testosterone, and eating more of it will not fix poor sleep or low energy from an untreated condition. If you feel tired all the time despite eating well, see a doctor and rule out medical causes first.
Where Maxentra fits next to your plate
Food and training come first. The CDC advises adults to do muscle-strengthening work on at least two days a week, per CDC: Physical Activity for Adults, and resistance training in older men has been studied widely; you can browse that work in PubMed: Resistance training and testosterone. Protein supports that effort.
A daily capsule like Maxentra is positioned to support energy, stamina and healthy testosterone already in the normal range, alongside diet, exercise and sleep. It does not replace meals. You can read how Maxentra works and the Maxentra benefits the brand describes, and if you go ahead, order from the Maxentra official website.

Is the RDA enough for men who lift weights?
The RDA of 0.8 grams per kilogram prevents deficiency, but sports nutrition groups suggest about 1.2 to 2.0 grams per kilogram for active adults. Most lifters over 40 do well in the lower half of that range.
Do I need protein shakes?
No. Shakes are a convenience. Eggs, dairy, fish, poultry, beans and tofu can cover most men's needs, and powders vary in quality because supplements are not FDA approved.
Can eating more protein raise testosterone?
No. Protein supports muscle repair when you train, but it does not raise testosterone. Ask a doctor about a morning blood test if you suspect low levels.
