The Leanest Animal Proteins
When seeking out the most protein-dense and calorie-efficient foods, lean animal proteins are often the first place to look. Their high biological value and complete amino acid profiles make them highly effective for muscle repair and satiety.
Skinless Chicken Breast and Turkey Breast
Skinless chicken breast is a powerhouse of lean protein, providing about 31 grams of protein per 100 grams for roughly 165 calories. Turkey breast is a very similar, excellent option, with around 29 grams of protein per 100 grams. These poultry options are incredibly versatile and can be baked, grilled, or stir-fried with minimal added fat to keep the calorie count low.
White-Fleshed Fish and Shellfish
Many types of white-fleshed fish, such as cod, halibut, and haddock, offer an impressive amount of protein for very few calories. A 100-gram serving of cod, for instance, contains around 22.8 grams of protein for only 105 calories. Shrimp is another top contender, offering approximately 24 grams of protein per 100 grams for just under 100 calories. These seafood options are also rich in important nutrients like B vitamins and selenium.
Low-Fat Dairy Products
For those who consume dairy, certain products offer a fantastic protein-to-calorie ratio. Non-fat Greek yogurt is packed with protein and probiotics, with about 10 grams of protein per 100 grams for around 59 calories. Low-fat cottage cheese is another excellent choice, providing approximately 11 grams of protein per 100 grams for 98 calories. These products are also great sources of calcium, which is important for bone health.
Plant-Based Powerhouses
Plant-based diets can also achieve a high protein intake with low calories, though some attention to variety is required to get all essential amino acids.
Tofu, Edamame, and Legumes
Tofu, particularly firm or extra-firm varieties, is a complete protein source that is very low in calories. A 100-gram serving provides about 8 grams of protein for 76 calories. Edamame is another soy-based option rich in protein and fiber, offering 11 grams of protein per 100 grams. Legumes like lentils and chickpeas also contribute significantly, providing both protein and complex carbohydrates for sustained energy.
Plant-Based Protein Powders
For an on-the-go or post-workout boost, plant-based protein powders like pea, soy, or hemp protein can be very calorie-efficient. These supplements offer a concentrated protein source without the extra fats or carbs found in many whole foods.

How to Build a Low-Calorie, High-Protein Diet
Prioritize Whole Foods
While protein powders can be useful, building your meals around whole food sources ensures you also get essential vitamins, minerals, and fiber. For breakfast, consider an omelet with egg whites and vegetables, or a bowl of non-fat Greek yogurt with berries. For lunch, a salad topped with grilled chicken or a shrimp and avocado mix is a satisfying option. Dinners can feature lean fish like cod or salmon with a side of steamed vegetables.
Read Nutritional Labels
Be mindful of preparation methods and ingredients. For example, frying chicken or adding heavy dressings to salads can significantly increase calorie and fat content. Similarly, always read labels for packaged products like protein bars, as many contain added sugars and unhealthy fats that undermine a low-calorie goal.
Embrace Variety
To avoid flavor fatigue and ensure a broad spectrum of nutrients, it's wise to mix up your protein sources. For example, have poultry one day, fish the next, and a plant-based meal after that. This rotation helps you benefit from the unique nutritional profiles of different foods.
Conclusion
Foods with the highest protein and lowest calories are primarily lean animal products like chicken breast, white-fleshed fish, and low-fat dairy, as well as plant-based options including egg whites, tofu, and legumes. Focusing on these nutrient-dense choices can significantly aid weight management by boosting satiety and preserving muscle mass. By prioritizing whole foods and being mindful of preparation, it is simple to create a diet that is both high in protein and low in calories, supporting your health and fitness goals.
