Breakdown of Macros in a Pound of Flank Steak
To fully understand the nutritional value of a pound of flank steak, it's essential to look at the macronutrient composition in detail. The figures can vary based on whether the steak is raw or cooked and the specific grade of beef. For a 1-pound (16 oz) serving of raw, lean flank steak, the macronutrient profile is highly favorable for those on low-carb or high-protein diets.
Protein Content
Protein is the most abundant macronutrient in flank steak. A 1-pound portion of raw, lean flank steak contains roughly 99 grams of protein. This makes it an excellent source of this essential nutrient, which is vital for building muscle, repairing tissues, and producing hormones and enzymes. For a typical person, this amount can more than cover the recommended daily protein intake, making it a highly effective food for muscle growth and recovery. When cooked, the protein content per ounce increases due to moisture loss. A 3 oz serving of cooked flank steak contains approximately 23 to 32 grams of protein, depending on the cooking method.
Fat Content
Flank steak is considered a leaner cut compared to other types of beef, but it still contains a notable amount of fat. A 1-pound portion of raw, lean flank steak has about 29 grams of total fat. This fat is a mix of saturated, monounsaturated, and polyunsaturated fats. The monounsaturated and polyunsaturated fats are generally considered healthier fats that can contribute to heart health. It's important to note that cooking methods can affect the final fat content. Broiling or grilling can help render and remove some fat, while pan-frying might add more depending on the oil used. For those monitoring their fat intake, trimming any visible excess fat before cooking is a simple way to reduce the overall fat and calorie count.
Carbohydrate Content
One of the most appealing features of flank steak for those on ketogenic or low-carb diets is its complete lack of carbohydrates. A pound of flank steak, like all unprocessed meats, contains 0 grams of carbs. This means it has no impact on blood sugar levels and is a perfect fit for carb-restricted eating plans. This also means it's free of dietary fiber and sugars, which are typically found in plant-based foods.

Cooking Methods and Their Effect on Macros
The preparation method significantly impacts the final macronutrient profile of your flank steak. Here's a look at how different cooking techniques can alter the final nutritional outcome:
- Grilling or Broiling: These methods use dry, high heat, which causes fat to drip away from the meat. This can result in a slightly lower fat and calorie count in the finished product. The cooked weight will be lighter than the raw weight due to moisture loss, which concentrates the protein and nutrients.
- Pan-Frying: Cooking in a pan with added oils or butter will increase the overall fat and calorie content. However, this method can also add flavor and create a nice crust on the steak. For a healthier option, use a minimal amount of healthy cooking oil.
- Stewing or Braising: Slow-cooking methods like stewing involve simmering the meat in a liquid. This can cause some water-soluble nutrients to leach into the cooking liquid. The end result can be rich and flavorful, but the nutrient density of the steak itself may differ slightly from other methods.
Conclusion
Understanding the macros for a pound of flank steak is crucial for meal planning, especially for those on specific diets like keto or high-protein regimens. A 1-pound portion is a potent source of protein, with zero carbohydrates, and a moderate amount of fat that can be controlled by trimming and cooking methods. While the raw nutritional data provides a baseline, considering the cooking process is key to accurately assessing the final macros. Its versatility and robust nutrient profile make flank steak an excellent choice for a healthy and satisfying meal.
Nutritional benefits of including flank steak
- High-Quality Protein: Flank steak provides a complete protein source with all essential amino acids, supporting muscle repair and growth.

How to incorporate flank steak into your diet
To get the most nutritional value and flavor from your flank steak, consider these preparation tips:
- Marinade for Tenderness: Given its tough nature, marinating flank steak for several hours can break down muscle fibers and infuse flavor. Use a citrus-based or soy-based marinade.
- Slice Against the Grain: Always slice flank steak against the grain after cooking. This shortens the muscle fibers and makes the meat more tender and easier to chew.
- Serve with Vegetables: Pair your flank steak with a side of roasted or sautéed vegetables to create a balanced meal. Broccoli, asparagus, or a simple side salad are great choices.
- Versatile for Recipes: Flank steak is ideal for dishes like fajitas, stir-fries, and steak salads, offering a variety of ways to enjoy its flavor.
- Meal Prep Friendly: Cook a large flank steak and use the leftovers for lunches throughout the week, incorporating it into different meals to keep things interesting.
Conclusion: A High-Protein, Low-Carb Powerhouse
For those seeking a high-protein, low-carbohydrate food source, a pound of flank steak offers an impressive nutritional profile. With a substantial protein count and a moderate, manageable amount of fat, it can serve as a cornerstone of many diet plans. By being mindful of cooking techniques, you can enjoy a flavorful, tender, and nutrient-dense meal that supports your health and fitness goals. Whether grilled, broiled, or pan-fried, understanding the macros for a pound of flank steak helps you make informed choices about your food.
