Protein Intake Calculator is a nutrition tool that estimates your daily protein requirement based on your body weight, activity level, and goal — whether muscle building, weight loss, or general health maintenance — using evidence-based guidelines from sports nutrition research.
How it works: It multiplies your body weight (in kg) by a protein factor (g per kg) calibrated to your activity level and goal. Sedentary adults need ~0.8g/kg (RDA minimum); athletes and muscle builders need 1.6–2.2g/kg. For weight loss, higher protein (1.8–2.4g/kg) preserves lean muscle during a calorie deficit.
When you need it: Users typically reach for Protein Intake Calculator when planning daily protein targets for a muscle-building program, ensuring sufficient protein during a weight loss diet to prevent muscle loss, checking if your current protein intake meets your fitness goals, or converting a protein gram target into food portions.
Key Facts
Approximate protein per serving for high-protein foods — useful for hitting your daily target.
| Food | Serving Size | Protein (approx.) | Notes |
|---|---|---|---|
| Chicken breast (cooked) | 100g | ~31g | Lean, versatile — highest protein density |
| Tuna (canned in water) | 100g | ~25g | Convenient, inexpensive |
| Eggs (whole) | 1 large | ~6g | Also provides healthy fats |
| Greek yogurt (plain) | 200g | ~17g | Also a source of calcium and probiotics |
| Cottage cheese | 200g | ~25g | High in casein — slow digesting |
| Whey protein powder | 1 scoop (~30g) | ~24g | Fast-absorbing — good post-workout |
| Lentils (cooked) | 200g | ~18g | Plant-based + high fiber |
| Tofu (firm) | 100g | ~17g | Complete plant protein |
| Ground beef 80/20 (cooked) | 100g | ~26g | Also high in fat — account in macros |
Protein quality matters — animal proteins contain all essential amino acids. Plant proteins (except soy and quinoa) are often incomplete. Combine different plant sources (rice + beans, for example) throughout the day to get all essential amino acids.
