How does the energy content of fat compare to the energy content of carbohydrates?

Answer 1

For every 1 gram of fat there are 9 kcals, and for ever 1 gram of carbohydrates there are 4 kcals. Carbohydrates get digested to produce glucose, which is the form of energy preferred by every cell in your body. When there is no glucose left, your body uses stored fat for energy.
