I need to lose weight

I had fallen off the diet wagon and notice that my pants are tighter now.  *HELP*  I didn’t snack or eat junk food.  Instead of having the usual vege dinner, I had been eating other dishes (without rice) for dinner.  During weekends, I would eat noodles for lunch and go out for dinner.   This has been happening since January.  Well, I guess I really cannot eat like a normal person.  I have to either look for the best weight loss supplement or start having vege dinner again.
