Why Focus on 50 Grams of Protein?
Protein is an essential macronutrient vital for numerous bodily functions, including building and repairing tissues, creating enzymes and hormones, and supporting immune health. While the RDA is a baseline, increasing intake to around 50 grams per day can support muscle growth, counteract age-related muscle loss in older adults, and promote satiety for weight management.
Animal-Based Sources to Hit Your Target
Animal proteins are complete proteins, containing all nine essential amino acids, making them effective for building and repairing muscle.
- Chicken Breast: A 100-gram serving offers about 31 grams of protein.
- Fish: A 170-gram salmon fillet provides over 35 grams of protein and omega-3s. A small can of tuna has about 25 grams.
- Greek Yogurt and Cottage Cheese: A cup of Greek yogurt contains 15–20 grams, while a cup of cottage cheese offers over 25 grams.
- Eggs: Two large eggs provide over 12 grams of protein.
Plant-Based Options for Your Protein Needs
Plant-based sources can easily contribute to a 50-gram target, especially when combined.
- Lentils and Legumes: One and a half cups of cooked lentils provide around 20 grams of protein. One cup of chickpeas offers about 15 grams.
- Tofu and Tempeh: About 150 grams of tempeh delivers 24 grams, and a similar serving of firm tofu provides around 20-30 grams.
- Quinoa: One cup of cooked quinoa provides about 8 grams.
- Nuts and Seeds: An ounce of almonds or pistachios has about 6 grams, while two tablespoons of chia seeds or peanut butter add 4-7 grams.

Meal and Snack Ideas for a 50g Target
Spread protein intake throughout the day for muscle synthesis and satiety.
- Breakfast: 1 cup Greek yogurt with protein powder and chia seeds (35-40g). Or, 3-4 eggs scrambled with spinach and cottage cheese.

How to Strategically Plan Your Intake
Planning is key. Meal prepping and knowing the protein content of foods helps. Focus on substantial protein at each meal and combine sources for complete nutrients.
Don't Obsess Over a Single Number
Individual needs vary. Active individuals may need more than 50 grams, while less active individuals may need less. Consistency and quality of sources are most important.
Conclusion
Reaching 50 grams of protein daily is achievable through a varied diet of lean meats, fish, dairy, eggs, and plant-based foods like legumes, tofu, and nuts. Strategic meal planning and smart snacking distribute intake for optimal health, muscle maintenance, and repair. A high-protein diet is accessible with planning and creativity.
