yes kilojoues convert down to joules which is the amount of energy in the body
total joules= total energy
more calories more energy
pounds are mass and calories are energy.
Kilo calorie or Large Calories
I would believe that 500 calories is 500 calories. So yes, they are equal in calorie amount.
food energy is measured in kilocalories (1000 calories equal 1 kilocalorie),
The difference between calories and Calories is that calories with a lowercase "c" refer to the energy content in food, while Calories with an uppercase "C" represent kilocalories, which are commonly used to measure the energy content of food. 1 Calorie is equal to 1,000 calories.
The more anything eats, the more energy it has. This is because with the food that you eat, you gain calories, and the more calories you eat, the more energy you have available.
If you intake more calories than you expend, you will gain weight. If you expend more calories than you intake, you will lose weight. It isn't exactly that simple, though. For example, 2000 calories in fruits and vegetables are considerably better for you than an equal number of calories in carbonated beverages. Calories matter - both those expended and those taken in. If you are at the correct weight for your height and continuously eat more calories than you expend, you will soon be overweight. And if you continuously eat fewer calories than you expend, you will soon be underwieght.
Fat. More calories =more heat=more energy.
Coconuts have a higher fat content than potatoes, which contributes to their higher energy density. Fats have 9 calories per gram, while carbohydrates in potatoes have 4 calories per gram. This difference in energy content explains why 100g of coconut contains more energy than an equal mass of dried potato.
Carbohydrates provide 4 calories per gram, while fats provide 9 calories per gram. This means that fats contain more than double the energy content of carbohydrates, making them a more efficient source of energy for the body.
Calories are basically a measurement of energy. To make your muscles move, your body needs energy, and it gets that energy from the food you've eaten. The more muscles you use, and the longer you use those muscles, the more energy(=calories) you use up.
