Tomatoes are a staple in many cuisines and for good reason. They are not only delicious and versatile but also offer a wealth of nutrients for a minimal caloric investment. At just 17 calories for a 92g serving, they are a weight-loss friendly food that can help you feel full and satisfied. Understanding the full nutritional profile beyond just the calorie count can help you appreciate their value in your diet.
The Macronutrient Breakdown
To better understand how the 17 calories in 92g of tomatoes are distributed, it's helpful to look at the macronutrient composition. The majority of the calories come from carbohydrates, while fat and protein make up the rest. This natural balance is a key reason why tomatoes are considered a healthy food choice.
- Carbohydrates: The primary source of energy, contributing around 75% of the total calories. This includes both natural sugars and dietary fiber, which aids digestion.
- Protein: A small but significant portion, accounting for about 17% of the calories. While not a primary protein source, it contributes to the overall nutritional value.
- Fat: Extremely low in fat, making up only about 9% of the calories. This makes tomatoes a great option for those watching their fat intake.
Comparing Tomatoes: Raw vs. Cooked
The preparation method can affect the nutritional profile and calorie count of tomatoes, though the changes are usually minor. Raw tomatoes, like the 92g serving discussed, are great for salads and sandwiches, providing a crisp, fresh flavor. Cooked tomatoes, such as those found in sauce, have different nutritional properties, most notably in their lycopene content.
- Increased Lycopene Absorption: Cooking tomatoes actually increases the bioavailability of lycopene, a powerful antioxidant that gives tomatoes their red color. This means your body can absorb more of this beneficial compound when the tomato is cooked.
- Concentrated Flavor: Roasting or simmering tomatoes removes water, which concentrates their natural sugars and intensifies their flavor, making them ideal for sauces and soups.
- Reduced Water Content: The process of cooking reduces the water content, which means that weight-for-weight, a cooked tomato product (like a sauce) will have slightly more concentrated calories than a raw one.
The Power of Lycopene and Other Nutrients
Beyond the basic macronutrients, tomatoes are a nutritional powerhouse, packed with vitamins, minerals, and antioxidants. These compounds offer a range of health benefits that make tomatoes more than just a low-calorie filler.
Health-Boosting Nutrients in 92g of Tomatoes:
- Lycopene: A key antioxidant that protects cells from damage and has been linked to a reduced risk of heart disease and certain cancers.
- Vitamin C: An essential nutrient and antioxidant that supports the immune system and skin health.
- Potassium: An important mineral for blood pressure regulation and heart health.
- Fiber: Aids digestion and promotes a feeling of fullness, which is beneficial for weight management.
- Beta-Carotene: An antioxidant that the body converts into vitamin A, supporting vision and immune function.
Incorporating Tomatoes into a Healthy Diet
Given their versatility, it's easy to add more tomatoes to your diet, whether you prefer them raw or cooked. From salads to soups, they can enhance flavor and nutritional value without adding excess calories.

The Benefits of a High-Water, High-Fiber Food
The high water content and dietary fiber in tomatoes play a crucial role in their ability to aid weight loss and promote satiety. With 95% water, a serving of tomatoes helps keep you hydrated. The fiber helps you feel full for longer periods, reducing the likelihood of overeating and curbing cravings. This combination is especially effective for managing appetite and maintaining a calorie deficit.
