Source: Web research, March 2026.
Filet mignon is a premium cut of beef taken from the tenderloin, the least-worked muscle along the spine, which makes it exceptionally tender with a fine grain and mild flavor. One 6oz steak (170g) contains approximately 371 calories, 34.3g of protein, and 25.2g of fat with zero carbohydrates. Per 100g, filet mignon delivers 218 calories, 20.2g of protein, and 14.8g of fat. It is leaner than ribeye or New York strip despite its reputation as a luxury cut. The high protein content makes it a solid muscle-building meal, and the absence of carbs fits carnivore and keto eating patterns. Filet mignon is also a meaningful source of iron (2.5mg per 100g), zinc (3.4mg), and vitamin B12 (3.7mcg), all critical for energy metabolism and red blood cell production. If you are hitting serious protein targets, a single steak covers over 34g.

Health Benefits of Filet Mignons
Filet mignon is one of the highest-quality protein sources available, providing 20.2g of complete protein per 100g with all essential amino acids. For anyone focused on muscle hypertrophy, the leucine content in beef protein directly stimulates muscle protein synthesis, making it a highly effective post-workout meal.
The iron content in filet mignon (2.5mg per 100g) is heme iron, the form most readily absorbed by the body compared to plant-based iron sources. Adequate iron levels directly support oxygen transport in the blood, which impacts athletic endurance and reduces fatigue during intense training.
Zinc at 3.4mg per 100g supports testosterone production, immune function, and wound healing. For anyone in their peak training years, zinc is a critical mineral that many people are deficient in. A single serving of filet mignon provides a substantial contribution toward the 8 to 11mg daily recommended intake.
Vitamin B12 at 3.7mcg per 100g exceeds the 2.4mcg daily recommended intake in a single serving. B12 is essential for nerve function, DNA synthesis, and red blood cell formation. It is only found in animal products, making red meat like filet mignon a reliable dietary source.
With no carbohydrates and a favorable protein-to-calorie ratio, filet mignon supports body recomposition goals when portioned appropriately within your overall calorie targets.
Dietary Considerations
Filet mignon is naturally gluten-free, dairy-free, and zero-carb, making it compatible with keto, carnivore, paleo, and Whole30 dietary frameworks. It is not suitable for vegan or vegetarian diets. With 218 calories per 100g and a strong protein content of 20.2g, it fits well into calorie-controlled plans for both cutting and bulking phases. The saturated fat content of 5.8g per 100g is moderate compared to fattier cuts. For weight loss, the high protein density keeps you full and supports lean mass retention during a deficit. No significant allergen concerns beyond beef itself. Filet mignon is lower in sodium at 50mg per 100g before seasoning, which is an advantage for anyone monitoring salt intake.
