Protein Needs Calculator
Calculate your daily protein requirements based on your weight, activity level, and fitness goals. Essential for muscle building, recovery, and overall health.
Why is Protein Important?
Protein is the building block of life, essential for muscle growth, repair, and maintenance. It's made up of amino acids that your body uses to build and repair tissues, produce enzymes, and support immune function.
Daily Protein Needs: Your protein requirements depend on your body weight, activity level, fitness goals, and overall health. Active individuals and athletes typically need more protein than sedentary people.
Protein Functions:
- • Builds and repairs muscle tissue
- • Supports immune system function
- • Produces enzymes and hormones
- • Maintains bone health
- • Provides energy when needed
- • Supports satiety and weight management
Protein Requirements by Goal:
- Maintenance: 1.2-1.6g per kg body weight
- Muscle Building: 1.6-2.2g per kg body weight
- Weight Loss: 1.6-2.4g per kg body weight
- Athletes: 1.4-2.0g per kg body weight
- Endurance: 1.2-1.4g per kg body weight

About Protein Needs
RDA (Recommended Daily Allowance): 0.8g per kg body weight for sedentary adults.
Active Individuals: 1.2-1.4g per kg for those who exercise regularly.
Athletes: 1.6-2.0g per kg for those in intense training programs.
Weight Loss: Higher protein intake helps preserve muscle mass during calorie deficits.
Muscle Building: Adequate protein is essential for muscle protein synthesis and recovery.
Frequently Asked Questions About Protein
Why is protein important for fitness?
Protein is the building block of life, essential for muscle growth, repair, and maintenance. It's made up of amino acids that your body uses to build and repair tissues, produce enzymes, and support immune function. For fitness enthusiasts, adequate protein intake is crucial for muscle building, recovery, and maintaining lean body mass during weight loss.
How much protein do I need daily?
Protein needs depend on your goals and activity level. For general health: 0.8g per kg body weight. For weight loss: 1.2-1.6g per kg. For muscle gain: 1.6-2.2g per kg. For athletes: 1.4-2.0g per kg. Our protein calculator automatically adjusts recommendations based on your specific goals and activity level.
What are the best protein sources?
Complete protein sources include animal products (meat, fish, eggs, dairy) and some plant sources (quinoa, soy). For muscle building, prioritize lean meats, fish, eggs, Greek yogurt, and whey protein. Plant-based options include legumes, nuts, seeds, and protein powders. Aim for variety to ensure you get all essential amino acids.
When should I eat protein?
Distribute protein intake evenly across 3-4 meals per day. Consume 20-30g protein within 30 minutes post-workout for optimal muscle recovery. Include protein at every meal to maintain steady amino acid levels. Casein protein before bed can help with overnight muscle recovery and protein synthesis.
Can I eat too much protein?
While protein is essential, excessive intake (over 2.5g per kg body weight) may not provide additional benefits and could potentially strain kidneys in those with existing kidney issues. For most healthy individuals, protein intakes up to 2.2g per kg are safe and effective for muscle building and weight management.
What about protein supplements?
Protein supplements can be convenient but aren't necessary if you meet your needs through whole foods. Whey protein is quickly absorbed and ideal post-workout. Casein is slower-digesting and good before bed. Plant-based proteins are excellent for vegetarians and vegans. Choose supplements that fit your dietary preferences and goals.
How does protein help with weight loss?
Protein helps with weight loss by increasing satiety, preserving muscle mass during calorie deficits, and requiring more energy to digest (thermic effect). Higher protein diets often lead to better body composition changes - more fat loss and less muscle loss. Aim for 1.2-1.6g per kg body weight when trying to lose weight.
