Rush suffers when he strays off politics.
Try eating egg white omelets, tuna, tasty veggies, soup, cereal bars.
I say it's a combination of weights, cardio, and diet that's going to do it for you. A diet with no exercise won't do squat. Your body gets used to getting no calories and tries to compensate, because it thinks it's starving.
Diets, by themselves never work and neither does occasional exercise without any change in your eating habits! If you have no motivation to get any exercise, chances are you'll never keep the weight off.
Rush is WRONG... You need some cardio!
