you are way off. You can go bust your *** in the gym and gain weight, get fatter, get unhealthier. Diet is everything. Try eating fast food all day everyday and go to the gym and see how it works out for ya. You can diet and not work out and lose weight, lose fat. your talking to someone that went to graduate school for this. i can educate you all day. your wrong. Diet is better then the gym, however the 2 combined is what produces the results. but if i had to pick one over the toher it would be a healthy diet everytime
