Am I excercising enough?

narc · Yahoo User

From July to August: Pilates and Yoga three days a week (alternating, an hour each)From August to whenever school starts: I plan on taking yoga and pilates classes (they're an hour each) around four times a week. Sometimes in my spare time, I do pilates for thirty minutes. I watch what I eat (most of the time). I avoid eating after 7 or sometimes 9 p.m. My goal is to get skinnier and to get abs. Is this schedule enough? Are there other effective ways (eating certain foods, natural ways, etc.) to lose weight? Any suggestions and extra information are welcome and appreciated!
