Calories in Skirt Steak: Nutritional facts for Skirt Steak Types

A 100-gram serving of raw skirt steak contains 185 calories. A 100-gram serving of grilled skirt steak contains 235 calories.

One kilogram (1000g) of raw skirt steak contains 1850 calories. One kilogram of grilled skirt steak contains 2350 calories.

The calorie content of one skirt steak depends on the weight of the cut, as a whole skirt steak can weigh between 1.5 to 2.5 pounds (680g to 1134g). A whole raw skirt steak weighing 1.5 pounds (680g) contains 1258 calories. A grilled skirt steak that had a raw weight of 1.5 pounds (680g) contains 1199 calories.

Skirt steak offers several health benefits stemming from the dense nutritional profile of the meat, which is rich in high-quality protein, essential minerals, and vitamins. The following points detail the key health advantages of consuming skirt steak.

• Promotes Muscle Health. Skirt steak is an excellent source of complete protein, providing all the essential amino acids required for building and repairing muscle tissue. A review by Carbone, J. W., & Pasiakos, S. M., 2019, "Dietary Protein and Muscle Mass: Translating Science to Application and Health Benefit," confirms that consuming high-quality protein is effective for maintaining muscle mass and strength.
• Supports Energy Metabolism. This cut of beef is rich in B vitamins, particularly niacin and vitamin B12, which are crucial for converting food into energy. A study by Tardy, A. L., et al., 2020, "Vitamins and Minerals for Energy, Fatigue and Cognition: A Narrative Review of the Biochemical and Clinical Evidence," details how B vitamins function as coenzymes in energy metabolism, helping to reduce fatigue.
• Aids in Red Blood Cell Formation. Skirt steak provides a significant amount of heme iron, a form of iron that is readily absorbed by the body. A report from the World Health Organization, 2001, "Iron Deficiency Anaemia," establishes that adequate intake of bioavailable iron is essential for the production of hemoglobin, the protein in red blood cells that transports oxygen, thereby preventing anemia.
• Boosts Neurological Function. The zinc and vitamin B12 found in skirt steak are vital for brain health and cognitive function. A review by Warthon-Medina, M., et al., 2015, "Zinc intake, status and indices of cognitive function in adults and children: a systematic review and meta-analysis," found that adequate zinc intake is positively associated with certain aspects of cognitive function.

Skirt steak consumption has potential downsides, mainly associated with the health risks of red meat intake and common preparation methods. The following points detail some of these disadvantages.

• Increased Cancer Risk from High-Heat Cooking. Grilling or pan-searing skirt steak at high temperatures can create heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs). A report by the National Cancer Institute, 2017, "Chemicals in Meat Cooked at High Temperatures and Cancer Risk," states that these chemicals have been found to be mutagenic, meaning they can cause changes in DNA that may increase the risk of cancer.
• Association with Cardiovascular Disease. High intake of red meat is linked to an increased risk of cardiovascular disease. A study by He, F. J., & MacGregor, G. A., 2018, "Role of salt intake in prevention of cardiovascular disease: controversies and challenges," showed that higher red meat consumption is associated with a greater risk of heart disease, partly due to the saturated fat content which can elevate LDL cholesterol.
• Higher Saturated Fat Content. Skirt steak is a fattier cut of beef compared to leaner options. A publication from the American Heart Association, 2021, "Saturated Fat," recommends limiting saturated fat intake because it raises low-density lipoprotein (LDL) cholesterol levels, which increases the risk for heart disease and stroke. An alternative with lower saturated fat is flank steak or top sirloin. A suggested consumption for red meat is a maximum of 350-500g (12-18oz) cooked weight per week.

Yes, skirt steak can be part of a healthy diet when consumed in moderation because the meat provides essential nutrients like high-quality protein, iron, zinc, and B vitamins. For heart health, when lean red meat is included in a balanced diet, the impact on cardiovascular risk factors can be neutral or even favorable. A study by O'Connor, L. E., et al., 2017, "A Mediterranean-style eating pattern with lean, unprocessed red meat has cardiometabolic benefits for adults with overweight or obesity," found that a healthy Mediterranean-style diet including lean red meat improved cardiometabolic disease risk factors. For brain health, the iron and vitamin B12 in skirt steak are crucial for neurological development and function. A review by Bourre, J. M., 2006, "Effects of nutrients (in food) on the structure and function of the nervous system: update on dietary requirements for the brain," explains the critical role of these micronutrients in maintaining the structure and function of the brain. The high protein content also supports muscle synthesis and maintenance, which is vital for overall physical health and metabolism, as detailed in the study by Paddon-Jones, D., & Rasmussen, B. B., 2009, "Dietary protein recommendations and the prevention of sarcopenia."

The calorie content of skirt steak changes based on whether the cut is an inside or outside skirt steak. The inside skirt steak is the lowest calorie option, containing 210-230 calories per 100-gram cooked serving. This lower calorie count is due to the cut being leaner with less intramuscular fat. The outside skirt steak is the highest calorie option, containing 240-260 calories per 100-gram cooked serving. The higher calorie value of the outside skirt reflects the greater amount of marbling and fat, which also gives the meat a more tender texture and robust flavor.

No, skirt steak is not healthier than steak tips because steak tips are cut from the leaner sirloin, while skirt steak comes from the fattier diaphragm muscle, resulting in a healthier nutritional profile for steak tips. The skirt steak macros show a higher calorie and fat content, with a 100-gram cooked serving containing 235 calories and 13.9 grams of fat, compared to 206 calories and 10.7 grams of fat in sirloin tips. The lower fat content in steak tips, especially saturated fat, makes the cut a better choice for heart health, as choosing leaner meats helps manage cholesterol levels (Sacks, F. M., et al., 2017). Both cuts provide high-quality protein, but the lower fat-to-protein ratio in steak tips makes the meat a more efficient source for muscle building and repair (Phillips, S. M., 2014). Both skirt steak and steak tips are excellent sources of essential nutrients like iron, zinc, and vitamin B12, which are vital for energy production and cognitive health (Audebert, M., et al., 2013), but the overall nutritional advantage belongs to steak tips due to the lower fat and calorie metrics.

The cooking method directly reduces the serving size of skirt steak per person. High-heat cooking methods like grilling, broiling, or pan-searing cause the meat to shrink as moisture evaporates and fat renders out. This process decreases the final weight of the cooked steak. For instance, an 8-ounce (227g) raw skirt steak will yield a cooked portion of about 6 ounces (170g). A helpful rule of thumb for portioning is to purchase 25% to 30% more raw weight than the desired cooked serving size to account for this shrinkage.

The skirt steak is a long, flat cut of beef from the diaphragm muscles of the cow. For much of history, this cut was considered less desirable due to a coarse texture and was often trimmed away or ground into minced meat. The origin of skirt steak as a primary dish is rooted in the culture of Mexican vaqueros(cowboys) working on ranches in South and West Texas. Ranch owners would give these workers the less-wanted cuts of beef, including the skirt steak, as part of the pay. The vaqueros developed the method of marinating the tough meat to tenderize the cut and then grilling the steak quickly over a hot fire. This preparation became known as fajitas, a term derived from the Spanish word "faja," which means "belt" or "girdle," referencing the shape of the steak. The dish gained widespread popularity in the United States starting in the 1970s and 1980s, which elevated skirt steak from an obscure cut to a prized piece of beef. In other cultures, such as Argentina, the outside skirt (entraña) became a cherished part of the asado or barbecue, valued for a rich, beefy flavor.
