How Many Calories Are in a Serving of Grilled Beef Tenderloin?

A 150-gram serving of grilled beef tenderloin contains about 320 calories. Tenderloin is one of the leanest cuts of red meat, so it has noticeably fewer calories than fattier cuts of the same weight, such as ribeye or ribs. The meat is high in protein and has almost no carbohydrates. For this reason, it is a popular choice for people who want to maintain muscle mass or manage their calorie intake; 150 grams of cooked tenderloin provides about 40 grams of protein. How does the cooking method affect the calorie count? Grilling or pan-searing tenderloin without added oil keeps the total calorie count low. In contrast, cooking a tenderloin with plenty of butter or frying it in oil can add 100–150 calories to the same serving; the added fat contributes calories separately from the meat itself. The level of doneness has almost no effect on the calorie count. The difference between rare and well-done tenderloin is only a few calories because the loss is mainly water, not fat. How do side dishes change the total calorie count? Sauces and side dishes served with tenderloin can contain more calories than the meat itself. Creamy mushroom sauce or mashed potatoes with butter can easily double the meal's total calories, while grilled vegetables or a green salad keep the total lower. For someone tracking calories, tenderloin on its own is a reliable choice; sauces and side dishes are the main things to consider. Even a handful of french fries can bring the total above 200 calories. How does tenderloin compare with other cuts of red meat? A 150-gram ribeye contains about 430–450 calories, while the same weight of ribs can exceed 500 calories; tenderloin at 320 calories is considerably lower. The difference comes from fat content: tenderloin comes from the least-used muscle and therefore accumulates the least fat. Ground beef varies widely depending on its fat content. A 150-gram patty made with ground beef that is 20% fat can contain 100–150 more calories than tenderloin. Tenderloin ordered at a restaurant generally has more calories than tenderloin made at home; butter sauce or an oil glaze added before serving can add nearly 100 calories without being noticed. Resting the meat does not change its calorie count but helps retain its juiciness. Letting grilled tenderloin rest for a few minutes before slicing makes the same serving feel less dry and more satisfying. This does not reduce its calorie count, but it can help the serving feel more filling. As a general guide, a piece of tenderloin about the size and thickness of your palm is close to a 150-gram serving. This is a useful starting point for estimating a serving when no scale is available.
