13 Leanest Meats and Protein Sources for a Healthy Diet

Finding the right balance between getting adequate protein and managing your fat and calorie intake is essential for optimal health. Lean protein sources offer an excellent solution, providing the nutrients your body needs for muscle maintenance, tissue repair, and satiety without excessive calories or unhealthy fats.

Protein plays a crucial role in nearly every bodily function, from building and preserving muscle mass to regulating hormones and supporting immune function. Research indicates that adequate protein intake can also help promote feelings of fullness, making it valuable for those managing their weight.

According to dietary guidelines, adults should aim for approximately 10-35% of their daily calories from protein sources. For someone consuming 2,000 calories daily, this translates to about 50-175 grams of protein, though individual needs may vary based on activity level, age, and health goals.

Whether you prefer animal-based or plant-based options, there are numerous lean protein sources to choose from. Here are 13 of the leanest meats and protein foods to incorporate into your diet.

1. White Fish Varieties

White-fleshed fish ranks among the leanest protein sources available, offering exceptional nutritional value with minimal fat content. A 3.5-ounce serving typically provides 20-25 grams of protein, less than 3 grams of fat, and only 85-130 calories.

Popular white fish options include cod, haddock, halibut, tilapia, sea bass, and flounder. These fish are naturally low in fat while being rich in essential nutrients like vitamin B12, selenium, and phosphorus.

While white fish contains less omega-3 fatty acids compared to fattier fish like salmon or mackerel, incorporating both types into your diet ensures you receive a complete range of nutritional benefits. White fish excels for low-calorie, high-protein meals, while fatty fish provides heart-healthy omega-3s.

Key benefits: White fish delivers high-quality protein with minimal calories and fat, making it ideal for weight management while supporting muscle maintenance and overall health.

2. Skinless Chicken Breast

Chicken breast without skin is a classic lean protein choice, delivering approximately 30 grams of protein per 3.5-ounce serving with only about 3.5 grams of fat and 165 calories.

The key to keeping chicken breast lean is removing the skin, which contains most of the fat. A serving of chicken breast with skin contains nearly twice the fat and 25% more calories than skinless breast meat. You can remove the skin before or after cooking with similar results.

White meat cuts like breasts and tenderloins are leaner than dark meat portions such as thighs and drumsticks. Chicken breast also provides significant amounts of B vitamins, particularly niacin and B6, which support energy metabolism.

Cooking tip: To prevent dry chicken breast, try marinating before cooking, using moist-heat cooking methods, or monitoring internal temperature carefully to avoid overcooking.

3. Turkey Breast

Similar to chicken breast, turkey breast is an excellent lean protein source when prepared without skin. A 3.5-ounce serving provides about 30 grams of protein, 1-2 grams of fat, and approximately 135 calories.

Turkey breast offers a complete amino acid profile, meaning it contains all nine essential amino acids your body cannot produce on its own. It’s also rich in selenium, zinc, and B vitamins, particularly B3 and B6.

Ground turkey can also be a lean option when you choose breast meat that’s at least 93% lean. This makes an excellent substitute for higher-fat ground meats in various recipes.

4. Lean Beef Cuts

Beef can absolutely be part of a lean protein diet when you select the right cuts. Lean beef is defined as containing less than 10 grams of total fat and no more than 4.5 grams of saturated fat per 3.5-ounce cooked serving.

Look for cuts with “loin” or “round” in the name, such as sirloin, tenderloin, top round, or eye of round. A 3.5-ounce serving of lean beef provides about 25-27 grams of protein along with important nutrients like iron, zinc, and vitamin B12.

For ground beef, choose options that are at least 90% lean, preferably 93% or 95% lean. A 4-ounce cooked burger made with 95% lean ground beef contains approximately 24 grams of protein and only 5-6 grams of fat.

Beef is particularly valuable for its high bioavailability of iron and zinc, making it an excellent choice for preventing nutritional deficiencies.

5. Pork Tenderloin

Often called “the other white meat,” pork tenderloin rivals chicken breast in leanness. A 3.5-ounce serving contains approximately 21 grams of protein, less than 3 grams of fat, and only 120 calories.

Other lean pork cuts include pork loin chops and sirloin roasts. When preparing pork, trim any visible fat from the edges to reduce fat content further. Despite being lean, pork tenderloin remains tender and flavorful when cooked properly.

Pork provides an excellent source of thiamine (vitamin B1), which plays a critical role in energy metabolism, as well as selenium, phosphorus, and zinc.

6. Bison and Venison

Game meats like bison (buffalo) and venison (deer) are naturally leaner than conventional beef. Bison contains about 24 grams of protein per 3.5-ounce serving with only 2-3 grams of fat and approximately 140 calories.

Because bison and other game meats are often grass-fed or wild, they tend to have a healthier fat profile with higher levels of omega-3 fatty acids compared to grain-fed beef. This results in a more favorable omega-3 to omega-6 ratio, which may help reduce inflammation.

The leaner nature of game meats means they can dry out more easily during cooking, so use lower temperatures and avoid overcooking for best results.

7. Shrimp and Shellfish

Shrimp stands out as an exceptionally lean protein source, providing 22 grams of protein, only 2 grams of fat, and about 110 calories per 3-ounce serving. Other shellfish like crab, lobster, and scallops offer similar nutritional profiles.

While shrimp contains dietary cholesterol (approximately 150mg per serving), current research suggests that dietary cholesterol has minimal impact on blood cholesterol levels for most people. The more significant factors affecting heart health are saturated and trans fats.

When purchasing shrimp or shellfish, opt for plain frozen varieties rather than breaded or pre-seasoned options, which often contain added fats and sodium. Shellfish also provides valuable minerals like selenium, zinc, and copper.

8. Plain Greek Yogurt (Non-Fat or Low-Fat)

Greek yogurt undergoes a straining process that removes liquid whey, resulting in a thicker, more protein-concentrated product. A 6-ounce serving of non-fat Greek yogurt contains approximately 15-20 grams of protein, virtually no fat, and only 100 calories.

Compared to regular yogurt, Greek yogurt provides nearly double the protein per serving. It’s also an excellent source of calcium, providing 15-20% of daily needs, along with probiotics that support digestive health.

Choose plain varieties to avoid added sugars, then customize with fresh fruit, nuts, or a small amount of honey if desired. Greek yogurt works well as a base for smoothies, a substitute for sour cream, or simply enjoyed on its own.

9. Low-Fat Cottage Cheese

Cottage cheese is a protein powerhouse, offering 28 grams of protein per cup of 2% low-fat cottage cheese, with only 2.5 grams of fat and approximately 180 calories. Non-fat versions provide similar protein with even fewer calories.

This dairy product contains casein protein, which digests slowly and provides a steady release of amino acids. This makes cottage cheese particularly valuable as a pre-bedtime snack for supporting overnight muscle recovery and reducing muscle breakdown.

Beyond protein, cottage cheese supplies significant amounts of calcium, phosphorus, selenium, and B vitamins. The increased availability of single-serving containers makes it convenient for on-the-go nutrition.

10. Egg Whites

While whole eggs are nutritious, egg whites provide pure protein with virtually no fat. One large egg white contains about 3.6 grams of protein, less than 0.5 grams of fat, and only 17 calories.

Egg whites are composed primarily of water and protein, with the protein being highly bioavailable, meaning your body can efficiently use it. They’re also naturally low in sodium and contain no cholesterol.

You can purchase egg whites in cartons for convenience, or separate them from whole eggs at home. Pasteurized liquid egg whites and powdered egg white products are safe to consume without cooking, making them convenient for protein shakes and smoothies.

11. Legumes: Beans, Lentils, and Peas

Legumes represent excellent plant-based lean protein sources. A half-cup serving of cooked legumes provides 7-9 grams of protein, less than 1 gram of fat, and 110-130 calories, depending on the variety.

Popular options include black beans, kidney beans, chickpeas, lentils, black-eyed peas, and split peas. Beyond protein, legumes deliver substantial fiber (6-8 grams per serving), which supports digestive health, blood sugar control, and cholesterol management.

While legumes are lower in certain essential amino acids (particularly methionine), combining them with whole grains throughout the day provides complete protein. Legumes also offer folate, iron, magnesium, and potassium.

Research indicates that regular legume consumption may help reduce cholesterol levels, improve blood sugar control, and support heart health.

12. Tofu and Tempeh

Soy-based proteins like tofu and tempeh provide complete plant proteins containing all essential amino acids. A 3-ounce serving of firm tofu contains about 9 grams of protein, 4 grams of fat, and 70 calories.

Tofu’s neutral flavor and versatile texture allow it to absorb marinades and seasonings well, making it adaptable to various cuisines. Firmer varieties work well for grilling or stir-frying, while softer types blend smoothly into sauces and desserts.

Tempeh, made from fermented soybeans, offers a firmer texture and nuttier flavor than tofu, with slightly higher protein content (about 15 grams per 3 ounces). The fermentation process may also enhance nutrient absorption and provide beneficial probiotics.

If you prefer to avoid genetically modified foods, choose organic soy products, as organic certification prohibits genetic modification.

13. Low-Fat Milk

Low-fat milk (1% milk fat) provides an easy way to incorporate lean protein into your diet. One cup contains 8 grams of protein, 2 grams of fat, and about 100 calories, compared to whole milk’s 8 grams of fat and 150 calories per cup.

Milk proteins include both whey and casein, offering both fast and slow-digesting proteins. This combination supports muscle protein synthesis effectively, making milk a popular post-workout beverage.

Beyond protein, milk provides calcium, vitamin D (when fortified), potassium, and B vitamins. These nutrients support bone health, muscle function, and overall metabolism.

Some research suggests that the type of milk fat may not be as problematic for heart health as once believed, so discuss with your healthcare provider which option best suits your individual health needs.

Bonus Options Worth Considering

Powdered Peanut Butter

Traditional peanut butter contains healthy fats but packs significant calories (around 190 per 2 tablespoons). Powdered peanut butter, made by pressing out most of the oil, contains about 70% fewer calories while maintaining much of the protein.

Two tablespoons of powdered peanut butter provide approximately 6 grams of protein, 1.5 grams of fat, and only 50 calories. Reconstitute it with water for a spread, or add the powder directly to smoothies, oatmeal, or yogurt.

Canned Tuna in Water

Canned tuna packed in water (not oil) is an affordable, convenient lean protein source. A 3-ounce serving provides about 20 grams of protein, less than 1 gram of fat, and approximately 100 calories.

Choose chunk light tuna to minimize mercury exposure, and limit consumption to 2-3 servings per week as a precautionary measure. Tuna provides selenium, vitamin D, and B vitamins along with its impressive protein content.

How to Choose the Leanest Meats

When shopping for lean protein, keep these guidelines in mind:

For poultry: Select breast meat and remove the skin. White meat is leaner than dark meat.

For beef and pork: Look for cuts with “loin” or “round” in the name. Choose ground meat that’s at least 90% lean, preferably 93-95% lean.

For fish: White-fleshed fish varieties are leanest, though fattier fish provide valuable omega-3s and should also be included in your diet.

For dairy: Select low-fat or non-fat options when protein is your primary goal. Greek yogurt and cottage cheese offer the most protein per serving.

For plant proteins: Legumes, tofu, and tempeh provide lean protein with fiber and other beneficial nutrients.

Cooking Methods for Lean Proteins

The cooking method you choose significantly impacts the final fat and calorie content of your protein:

Best methods for keeping proteins lean: Grilling, broiling, baking, roasting, steaming, poaching, or air frying. These methods require little to no added fat.

Methods that add fat: Deep frying, pan-frying in oil or butter, and breading add significant calories and fat.

Healthy flavor boosters: Use herbs, spices, citrus juice, vinegar-based marinades, and low-sodium seasonings instead of creamy sauces or excessive oils.

Building Balanced Meals with Lean Protein

While lean protein is important, balanced nutrition requires variety. Structure your meals to include:

• Lean protein: 3-4 ounces per meal (about the size of a deck of cards)
• Non-starchy vegetables: Fill half your plate with colorful vegetables
• Whole grains or starchy vegetables: Include moderate portions for energy and fiber
• Healthy fats: Add small amounts of nuts, seeds, avocado, or olive oil

This balanced approach ensures adequate protein while providing essential vitamins, minerals, fiber, and healthy fats your body needs.
