How do our bodies respond to fats and sugars?

Our bodies respond to fats and sugars by breaking them down into usable energy. Fats are metabolized into fatty acids and glycerol, which can be used for energy or stored for later use. Sugars, on the other hand, are quickly converted into glucose, providing an immediate source of energy for cells. Both nutrients play essential roles in metabolism, but excessive intake can lead to health issues like obesity and insulin resistance.
