Fitness Question?

[bdg1115]

I have been going to the gym now for about a month and a half. I go pretty much every day. Monday - Friday, and just do cardio on the weekends, like basketball. During that gym time I am there for about 2 - 3 hours. I do upper body for a while every other day, and cardio for the remaining time I am there. I play raquet ball for about an hour and a half with a few friends. My question is, why am I not seeing any results from the gym? Even the scale tells me I have not lost any weight, I have gained a few pounds. My diet is not bad. I guess I could eat a little more. I drink 2 cups of coffee during the day, and maybe a muffin for breakfast, and then Subway, or some dinner after I get out of the gym. I dont even see any physical change. In the gym I can tell its going well, I am stronger and my cardio has increased. Any ideas on why I am not shedding pounds, or looking slimmer?

Thanks in advance..
