Hey Jessica. If you want to lose 30 pounds in 2 1/2 months your in for a tough one. I've been going to the gym, 4 days a week since february, and I have lost 15 pounds. But I have also gained muscle. If you want to lose weight , my suggestion is: Cut Down meal sizes, Don't eat junk food or don't snack between meals. Also you have to do a lot of cardio workouts, like running or roller blading for 30 minutes a day.
