While it is technically correct that cardio activity will use fat to fuel energy output, this process usually only lasts as long as the session itself, and because we gradually adjust to certain levels of intensity the body increasingly resists shedding unwanted weight when routinely using this method: this is why varying one's cardio intensity levels is mandatory if we wish to optimize fat loss. Weight training, however, will work one's body much more intensely than most forms of cardio will, thus stimulating a greater metabolic response, which will ultimately lead to increased fat loss above and beyond that directly attributable to aerobic work.
Avoid Junk Food – While you are at it, make sure that you do not eat junk food by any chance. By eating junk food, you are creating your chances of getting slim, very slim. Junk food like fries and burgers and flavored sodas are the worst enemy when you are aiming to lose weight. Instead of snacking on these, you must eat nuts, and fruits when feeling hungry. https://www.youtube.com/watch?v=TyXnVTALGM0
