This happens on a complex molecualr level. The calories aren't actually "made". They come from molecules, polymers, macromolecules, and monomers. This happens when amino acids, glucoses, and atoms combine to form molecules. Different molecules contain things like lipids (fats) or sugars (in sugar and starches) or proteins, which are what we know of as calories for energy.
calories are energy. food contains calories, so when you eat food, the calories within the food power your body.

Calories are just a measurement of energy you get from eating or drinking something. Food, was made to give us energy so that we can stay alive.
There are no differences between "calories" and "Food Calories" when it comes to measurement; they refer to the same unit of energy. Therefore, 732.0 calories is equivalent to 732.0 Food Calories. In dietary terms, Food Calories are often denoted with a capital "C" (Cal) to distinguish them from small calories (cal), with 1 Food Calorie (Cal) equal to 1,000 small calories (cal). Thus, 732.0 calories equals 732.0 Food Calories.
Fats are not in calories but in food. Food nutrients (and fats are one of them) usually have calories.
