I recently saw that the calorie amounts put on food labels are in kilo calories. When they say that you usually need around 2,000 calories in a day, are they saying you need 2,000 kcal or 2,000 normal calories? My chemistry teacher says the latter, but I am doing research and I can’t find an answer. If it is the latter, it doesn’t seem right that a serving of chips would have 160,000 calories.
The kcal is the measurement of calories in food. 1 kilocalorie is the same as 1 calorie (C). A kilocalorie is the amount of heat necessary to raise the temperature of one kilogram of water one degree Celsius- which is why macronutrients (fat, protein, carbohydrates) literally provide us energy.
