I'm stunned that there is anybody here who actually thinks exercising has anything to do with reducing body weight, alone.
I thought we were all clear. Body is machine, we fuel it. Body covers itself with spare fuel. Body doesn't get that fuel, uses spare fuel in fat cells.
Exercise has nothing to do with that other than exacerbating the fuel requirements.
It would if everything else remained constant, but it doesn’t. Runners even have a term for the appetite increase that occurs as a result of all the running, “Runger.”
That said, if you do want to lose body fat , combining exercise and diet will work faster than just diet alone.
