A medium-sized raw tomato (around 123 grams) contains approximately 22 calories. Converting that to the standard scientific unit for energy, a single tomato typically contains between 92 and 93 joules, or 0.092 and 0.093 kilojoules. This value is an estimate, as the exact energy content can vary slightly depending on factors like the tomato's size, ripeness, and variety.

Carbohydrates, fats, and protein are the energy-yielding nutrients that provide 100% of a diet's energy. These macronutrients are what makes up energy in food, fueling every process and activity your body performs, from breathing to running.

A single gram of fat contains more than twice the calories of a gram of protein or carbohydrate. Understanding what nutrients contain calories is fundamental to making informed dietary choices and effectively managing your energy intake.

According to the University of Rochester Medical Center, fats supply more than twice as many calories per gram as either carbohydrates or proteins, making fat the most energy-dense macronutrient. This article explores what provides the most energy in food, examining the roles of these key nutrients and how your body uses them for fuel.

On average, the human body is only about 25% efficient at converting food energy into mechanical energy, with the rest dissipated as heat. Understanding **what type of energy is held in food?** is the first step to appreciating this incredible biological process that fuels every aspect of our lives.

Fats, with 9 kilocalories per gram, contain the highest energy value of all macronutrients. This highlights the crucial need to understand **what does energy mean in nutritional information** to effectively manage your dietary intake and overall health.

The average person needs between 1,600 and 3,000 calories per day, but the way that energy is displayed on food packaging can be confusing. Understanding **what does kcal mean behind a product label?** is key to managing your intake effectively and making informed dietary decisions.

According to the National Institutes of Health, a calorie is the amount of energy required to raise the temperature of 1 kilogram of water by 1 degree Celsius. This might be confusing, but there is a simple way to explain calories by using familiar concepts and analogies that make the science of nutrition much more accessible.
