Understanding Steak Macronutrients
A steak is a prized source of high-quality protein, but its full nutritional story depends heavily on the cut and how it's prepared. The term 'macros' refers to the three primary macronutrients: protein, fats, and carbohydrates. For steak, the carb count is virtually zero, making it a staple of low-carb and ketogenic diets. The real variation comes down to its fat content, which directly impacts the total calorie count.
Protein is the most consistent macro, with most beef cuts delivering a high concentration of complete protein, which is essential for muscle repair and overall bodily functions. A 20 oz steak, regardless of the cut, will deliver a massive amount of protein, often exceeding daily recommended values. The fat content, however, is the swing factor. A well-marbled ribeye will have a significantly higher fat and calorie count than a lean cut of top sirloin. When tracking macros, it’s critical to account for this variation, as ignoring it can dramatically affect your daily calorie intake.
How Steak Cut Affects Macros
The choice of steak cut is the most important factor in determining its macronutrient breakdown. Different cuts have varying degrees of marbling (intramuscular fat), which accounts for the wide range of fat and calorie counts. Leaner cuts offer a higher protein-to-fat ratio, while fattier cuts provide more calories and a richer flavor.
- Lean Cuts: Options like top sirloin and tenderloin (filet mignon) are known for being lean and tender. A 20 oz cooked portion of select, lean-trimmed tenderloin contains about 1145 calories, with 175g of protein and 44g of fat. A raw 20 oz top sirloin has even lower figures, but will concentrate macros slightly upon cooking. These cuts are ideal for those on a calorie-controlled or high-protein diet.
- Fattier Cuts: Ribeye and New York Strip are beloved for their rich flavor, which comes from their substantial marbling. A 20 oz cooked ribeye can contain around 1474 calories, 142g of protein, and 100g of fat. Some restaurant preparations can push this even higher due to added butter or seasoning. The higher fat content provides more calories, making these cuts a potent energy source.
Cooking Methods and Their Impact on Macros
The way you prepare a steak can also alter its final macro count. While the protein content remains largely stable, the fat and calorie levels can be influenced by the cooking process.
- Grilling or Broiling: These methods use high, direct heat, allowing excess fat to drip away from the meat. This can result in a slightly lower fat content compared to pan-searing, especially with fattier cuts. It's an excellent method for retaining the steak's natural flavor while managing fat intake.
- Pan-Searing: Cooking in a skillet often involves adding oil or butter to achieve a flavorful crust. This adds extra calories and fat to the final macro count, especially if the pan is not drained. While delicious, this method is less macro-friendly than grilling if not done with minimal added fats.
- Resting the Meat: A crucial step often overlooked is letting the steak rest after cooking. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful steak. While resting doesn't change the macros, it is key to a perfectly cooked steak.

Sample Macro Breakdown by Steak Cut
| Cut (20 oz Cooked) | Calories | Protein (g) | Fat (g) | Notes |
|---|---|---|---|---|
| Tenderloin (Lean) | ~1145 | ~175 | ~44 | Significantly lower fat and calorie count |
| Ribeye (Marbled) | ~1474 | ~142 | ~100 | Richer flavor, higher fat and calorie count |
| Top Sirloin (Lean) | ~765* | ~124* | ~26* | Leanest option, excellent protein ratio (*based on pre-cooked data, final macros will differ) |
| Restaurant Ribeye | ~1480 | ~143 | ~101 | May contain higher sodium and fat due to seasoning and butter |
*Note: The macros for the top sirloin are based on pre-cooked data from a 20 oz cut. Cooking will reduce water weight and potentially some fat, concentrating the remaining macros into a smaller final weight. The cooked macros for lean-trimmed tenderloin and ribeye are based on cooked weights.
A Quick Guide to Macro-Friendly Steak
For those focused on lean protein, top sirloin or tenderloin are the best choices. Opt for grilling or broiling to minimize added fats and allow some marbling to render off. Pay close attention to portion sizes and the cooking process, as these are the two main variables you can control to align your steak with your dietary goals. By choosing your cut wisely and cooking mindfully, a 20 oz steak can be a powerful and delicious tool in your nutritional plan, whether you're building muscle, managing weight, or following a low-carb diet.
Conclusion
Ultimately, there is no single answer for what are the macros for 20 oz steak. The nutritional profile is highly dependent on the specific cut and how it's prepared. While leaner cuts like tenderloin and top sirloin offer a higher protein-to-fat ratio, fattier cuts such as ribeye and New York strip provide a richer flavor and more calories from fat. By understanding the differences and choosing your cooking method carefully, you can enjoy a hearty steak that perfectly fits your nutritional strategy. Always prioritize whole, unprocessed meat and be mindful of portion sizes for optimal health benefits.
