Fat let your friend`s body in the form of carbon dioxide and water. Or CO2 and H2O
Explanation:
First of all, let's clarify something. Fat is nothing more than stored energy in the body to be used when needed. So, if your friend started a diet exercise regime that means he reduced his calory consumption which is the source of energy and he increased his energy consumption. Thus, the usage of energy stored in fat cells was activated. The energy made the cells shrink and create heat to keep the movement. That is why the fat/energy was expelled from his body in the means o water and carbon dioxide. Because these two elements are the ones involved in the heat, energy, exercise cycle.
The fat didn't leave his body. Your friend less consumption of fat forced your body to use the energy from the already consumed fat in your body, which in turns lowers the amount of fat visible to the eye. There's still fat in your friends body just not as much. A little fat is healthy for your body. <span />
