I really need help & advice!!!

I quit smoking 7 weeks and 4 days ago. Before that I was on a very slow (read: lazy) diet & exercise plan I created for myself and had already successfully lost 10lbs since January. I know my body pretty well (at least I used to) and I know what it takes for me to lose whatever amount of weight it is I need to lose. I've done it several times in my life.

But ever since I quit smoking, everything that used to work stopped working. I've stepped up my workouts to one and a half hours 4 times per week and have incorporated light weights and toning exercises. That wasn't working so I cut out the weights and now I'm doing a full 6 hours of cardio only per week. (And I'm not talking about leisurely walking on the treadmill) I've been on this program for 3 weeks now and have not shed a single pound. As a matter of fact, I GAINED (muscle, obviously) when I was doing the weights. So, yay, I'm more toned and I can breathe better but have not lost an inch so if my gown came in tomorrow, I would not fit into it.

I will admit that I am not doing too well on the dieting portion. Of course because of the quitting, I am not as disciplined with my eating as I used to be and it is extremely, 100 times more difficult to control my eating than when I used to smoke. Still, I eat 3 meals per day and I try to avoid carbs as much as possible.

I really need help, advice, or tips. I know that my body has changed since I quit and I just don't know how to make it lose weight anymore. Any advice from quitters?

I quit smoking about 8 years ago I think and at the same time got serious about my health. I went back to the basics of hard discipline, rice and beans (which are the building blocks of muscle) and lots of steamed veggies with chicken. That was very successful for the diet portion but physical activity was also in the mix. I mountain biked my way to 168 from 265. Not bad. I was also a published success story in Mens Fitness from Oct. 2000. Later when I incorporated weights I would level off to 185-191. That is pretty much where I am today! Hopefully this will help you but I know you can do it!!! Good luck.
