The short version
Eating well for men's health comes down to a few habits that research supports consistently, not to any single "superfood" or hormone-boosting trick. The pattern that holds up best for heart disease, diabetes, weight, and long-term health is a Mediterranean-style diet: mostly vegetables, fruit, beans, whole grains, nuts, fish, and olive oil, with moderate amounts of dairy and poultry and small amounts of red meat, sweets, and ultra-processed food.
- Protein at each meal, especially if you lift or are over 50.
- Fiber and plants: vegetables, fruit, beans, and whole grains at most meals.
- Less ultra-processed food, sodium, and added sugar, and less alcohol.
- A healthy weight, because body fat itself lowers testosterone.
A pattern that works
The Dietary Guidelines for Americans, the American Heart Association, and the DASH and Mediterranean research all point the same direction. A practical way to apply it:
| Eat more | Eat less |
|---|---|
| Vegetables and fruit (aim for half the plate) | Sugary drinks, sweets, and refined snacks |
| Beans, lentils, whole grains, oats | White bread, pastries, and other refined grains |
| Fish, especially fatty fish, about twice a week | Processed meats (bacon, sausage, deli meat) and large amounts of red meat |
| Nuts, seeds, olive oil | Fried food and foods high in saturated fat |
| Poultry, eggs, yogurt, and other lean protein | Salty packaged and restaurant food (the American Heart Association suggests aiming for less than 2,300 mg of sodium a day, ideally 1,500 mg for most adults) |
For blood pressure, cholesterol, and blood sugar targets and how diet moves each one, see our heart and metabolic health guides.
Protein
The official minimum (the RDA) is 0.8 grams per kilogram of body weight per day, about 65 grams for an 80 kg (176 lb) man. That is the amount to prevent deficiency, not necessarily the best amount for muscle. Many sports-nutrition and aging researchers suggest roughly 1.2 to 1.6 g/kg for men who lift weights or are older, and spreading it across meals (about 25 to 40 grams per meal) rather than eating most of it at dinner. Good sources include fish, poultry, eggs, dairy, soy, beans, and lean meat. If you have kidney disease, check with your doctor before raising protein. Combine protein with the plan in our strength training after 40 guide, since protein alone does not build muscle.
Weight, belly fat, and testosterone
Body fat, especially around the waist, lowers testosterone, and low testosterone makes it easier to gain fat, so the two reinforce each other. In men with obesity, losing weight often raises testosterone levels, though by how much varies. That is why weight loss, sleep, and exercise are usually the first steps before TRT in men without clear disease of the testicles or pituitary. See our low testosterone symptoms and TRT guide. For men with obesity, prescription medicines such as GLP-1 drugs are covered in the metabolic health guide.
Ultra-processed food
Ultra-processed foods (packaged snacks, soda, many ready meals, and most fast food) make up a large share of calories in the US diet. Large observational studies link high intake to weight gain, heart disease, and earlier death. In a small, tightly controlled NIH trial published in Cell Metabolism in 2019, people eating an ultra-processed diet ate about 500 more calories a day and gained weight compared with a minimally processed diet, even though the meals were matched on offered calories, sugar, fat, and fiber. These studies cannot prove which ingredient is the cause, but the practical advice is the same: build most meals from foods that look like the plants and animals they came from.
Processed and red meat have a separate link to cancer: the World Health Organization's cancer agency classifies processed meat as carcinogenic to humans and red meat as probably carcinogenic, mainly for colorectal cancer. Men are at higher risk of colorectal cancer than women, so see our cancer screening guide for when to start screening.
Diet trends, checked
| Approach | What the evidence says |
|---|---|
| Mediterranean / DASH | Best-supported patterns for heart health, blood pressure, and diabetes prevention. Easy to sustain. |
| Intermittent fasting | Works for weight loss mainly by lowering calories; trials show results similar to ordinary calorie cutting. Fine if you like it, not magic. Be careful if you take diabetes medicines. |
| Low-carb / keto | Can lower weight and blood sugar in the short term; long-term benefit over other diets is unclear, and saturated fat and LDL cholesterol can rise. Work with a clinician if you have diabetes or heart disease. |
| Carnivore | No good long-term trials; omits fiber, and heavy red and processed meat intake raises colorectal cancer concerns. Not recommended. |
| "Testosterone-boosting" foods | No food reliably raises testosterone in men whose levels are normal. Severe crash dieting and very low fat intake can lower it. See our testosterone boosters evidence check. |
Alcohol and supplements
Alcohol adds calories, disrupts sleep, raises blood pressure, and lowers testosterone at heavy intake. The US guidelines have long defined moderate drinking for men as no more than two drinks a day, and current evidence suggests that less is better; people with liver disease, who take certain medicines, or who are trying to cut down should talk to a clinician. For supplements, a food-first approach is best; vitamin D (if you are deficient), creatine, and protein powder are the ones with the clearest evidence. See our supplements guide.
Making it practical
- Start with one change, such as adding a vegetable to two meals a day or swapping soda for water or sparkling water.
- Plan protein first: choose the protein, then add vegetables and a whole-grain or starchy side.
- Keep default foods at home that make the better option the easy one: fruit, nuts, yogurt, canned beans, frozen vegetables, and canned fish.
- Read labels for sodium, added sugar, and ingredient lists rather than front-of-pack claims.
- Check your numbers (blood pressure, cholesterol, A1C, waist) at your next checkup to see whether the changes are working.
When to get help
See a doctor or a registered dietitian if you have diabetes, kidney disease, heart disease, or food allergies; if you are losing weight without trying; or if eating, dieting, or body image is taking over your life. Eating disorders affect men too and are often missed.
