Calorie Breakdown: Cooked vs. Raw Pork Tenderloin
The number of calories in pork tenderloin is not static; it depends on whether the meat is measured before or after cooking. The cooking process removes moisture, which concentrates the calories and nutrients in the meat, leading to a higher calorie count per ounce for cooked tenderloin compared to raw.
Cooked, Roasted Pork Tenderloin (4 oz)
A 4-ounce serving of cooked, roasted pork tenderloin is a popular and healthy protein choice. It is a dense, nutrient-packed portion with the moisture cooked out. The nutritional details for a roasted serving are highly favorable:
- Calories: Approximately 162 kcal
- Protein: Around 30 grams
- Fat: Around 4 grams
This makes cooked pork tenderloin an excellent option for those looking to maximize their protein intake while managing calorie consumption. Its high protein content promotes satiety, which can help with weight management.
Raw Pork Tenderloin (4 oz)
Before cooking, a 4-ounce portion of lean pork tenderloin has a slightly lower calorie count due to its higher water content. The calorie and macronutrient values for a raw, lean serving are different:
- Calories: Approximately 135 kcal
- Protein: Around 23.7 grams
- Fat: Around 3.9 grams
It is important to remember that these raw values are not representative of the final product you consume. Cooking causes a significant reduction in the meat's water weight, so a 4-ounce raw tenderloin will result in a smaller, more calorie-dense cooked portion.
The Full Nutritional Profile of Pork Tenderloin
Pork tenderloin is more than just a low-calorie meat. It is a nutrient-dense food packed with essential vitamins and minerals that support overall health. A single 4-ounce serving provides a substantial amount of crucial nutrients:
- B Vitamins: An excellent source of thiamin, niacin, vitamin B6, and vitamin B12, which are vital for energy metabolism, nerve function, and red blood cell formation.
- Minerals: It is a good source of selenium, phosphorus, and zinc, which play roles in thyroid function, bone health, and immune system support.
- High-Quality Protein: Pork contains all nine essential amino acids, making it a complete protein source essential for muscle growth and repair.

How Preparation Methods Influence Calories
While pork tenderloin itself is very lean, the way you prepare it can drastically alter its final calorie count. The key to keeping your meal heart-healthy is to choose cooking methods and ingredients that add minimal fat and sodium.
- Roasting or Grilling: These methods require minimal added fat and are ideal for preserving the tenderloin's low-calorie profile. Using a dry rub of herbs and spices is a flavorful, zero-calorie way to season the meat.
- Pan-Frying: This can increase calories if too much oil or butter is used. To keep it lean, use a minimal amount of a healthy oil like olive or avocado oil and blot any excess oil with a paper towel.
- Sauces and Glazes: Adding a sugary barbecue sauce or a heavy cream-based sauce can add hundreds of extra calories. Opt for light glazes made with Dijon mustard, balsamic vinegar, or fresh herbs instead.
Tips for Healthy Pork Tenderloin Preparation
- Trim All Visible Fat: Before cooking, take a moment to trim any excess silver skin or fat from the exterior of the tenderloin.
- Create a Low-Sodium Marinade: Avoid pre-seasoned tenderloins that can be high in sodium. A simple marinade of fresh lemon juice, herbs like thyme and rosemary, garlic, and a splash of olive oil will add flavor without excess salt.
- Serve with Nutrient-Dense Sides: Pair your lean pork tenderloin with roasted vegetables, a fresh salad, or whole grains to create a balanced, filling meal.
- Use Proper Portions: Aim for a 3-4 ounce serving of cooked meat, which is about the size of a deck of cards or the palm of your hand.
Health Benefits Beyond Calories
Lean pork tenderloin offers more than just a moderate calorie count. Its nutrient profile provides significant health advantages. The high-quality protein supports muscle maintenance and can aid in slowing age-related muscle loss. It also contains beta-alanine, an amino acid that helps your body produce carnosine, which can improve muscle performance and reduce fatigue. As a testament to its nutritional value, pork tenderloin can be certified as heart-healthy by the American Heart Association when prepared correctly, meeting specific criteria for total fat, saturated fat, and sodium.

Conclusion
In summary, a 4-ounce serving of cooked pork tenderloin provides approximately 162 calories, along with a significant amount of high-quality protein and essential nutrients. As one of the leanest cuts of pork available, it is an excellent choice for individuals focused on weight management, muscle maintenance, and heart health. The ultimate calorie count is dependent on the preparation method, so opting for simple cooking techniques like roasting or grilling and avoiding heavy sauces is the best approach to keep this protein source a healthy addition to your diet.
