I am 5'0" and currently weight 150 lbs. Ideally, I'd like to lose about 30 pounds or so. I have started eating very healthily, but I was wondering if my exercise routine is enough for me to lose 30 pounds. I would like to lose it by May 2012, so that gives me about 7 months. I have started running on the elliptical for 30 minutes twice a day, doing pilates for an hour 6 days a week, and also doing a bit of circuit training 3 days per week. Will all of this exercise, paired with my healthy eating be enough to lose 30 pounds in 7 months?
