International Metric Standard
Protein Per 100 Grams: International Metric Standards Across Animal Meats
Under the international metric standard, raw animal meats provide 19.5g to 24.0g of protein per 100g, while cooked animal meats deliver 26.0g to 32.5g of protein per 100g. Cooked pasture chicken breast (32.5g/100g) and cooked grass-fed top sirloin (31.5g/100g) provide the highest concentrations of bioavailable essential amino acids.
A 100g portion of whole pasture-raised red meat delivers over 2.0g to 2.4g of L-leucine, fulfilling 80%+ of the single-meal mTOR threshold, along with 100% of the daily requirement for vitamin B12 and high-affinity heme iron.

DIAAS Scoring & True Ileal Bioavailability
Animal meats score 1.20 to 1.33 on the DIAAS scale, meaning that every 100g of meat provides complete amino acid absorption without digestive enzyme saturation or gut distress typical of plant protein powders.
Micronutrient Synergy per 100g Serving
Beyond protein, 100g of grass-fed beef delivers 4.5mg zinc, 2.6mcg vitamin B12, 1.2g creatine, and 450mg carnitine, driving mitochondrial lipid oxidation and metabolic health.

Metric Kitchen Scale & Culinary Protocol
- 1. Set Digital Scale to Grams: Grams eliminate decimal rounding errors inherent in ounces, making macro logging exact down to single-gram increments.
- 2. 160g–170g Cooked Beef = 50g Pure Protein: To achieve a gold-standard 50g anabolic protein bolus, portion 160g to 170g of cooked grass-fed steak on your plate.
- 3. Rest Before Weighing Cooked Portions: Allow steaks to rest for 5–8 minutes so intra-fiber juices redistribute before cutting and placing on the scale.
Chef & Nutritionist Troubleshooting Protocol
Issue: Steak juice leaking onto scale during portioning
Cause: Slicing meat too quickly without resting. Fix: Rest 8 minutes on a wire rack so the meat reabsorbs liquid before portioning.
Issue: Nutrition app displaying conflicting 100g values
Cause: Database mixing raw vs cooked entries. Fix: Ensure you select '100% Grass-Fed Steak (Cooked)' when logging finished meals.
Frequently Asked Questions
How much protein is in 100g of raw beef?
Raw beef provides between 20g and 24g of protein per 100g, depending on the fat trim (Top Sirloin is ~23.5g, Ribeye is ~21.0g).
How much protein is in 100g of cooked steak?
Cooked steak provides 27g to 31.5g of protein per 100g due to thermal water concentration during cooking.
How many 100g servings do I need for 150g of daily protein?
You need approximately 480g to 500g of cooked meat per day (about 17 oz total cooked weight) to hit 150g of complete animal protein.
Why does cooked chicken breast have more protein per 100g than beef?
Chicken breast has virtually zero intramuscular fat, meaning nearly all non-water mass consists of protein, yielding 32.5g protein per 100g cooked.
Is 100g of animal protein equivalent to 100g of plant protein?
No. Animal protein has a complete amino acid spectrum and DIAAS score >1.20, whereas plant protein isolates score lower (0.60–0.85) due to limiting amino acids and antinutrient interference.
