I have been going to the gym at least three times a week for an hour of cardio (bike / treadmill / cross trainer) for weeks now and seem to be putting on weight (fat not muscle) rather than losing it. I have been eating about 1200 calories a day in order to try and improve my diet but am starting to get really down as nothing seems to be working. I have not made drastic changes to my diet or exercise routine - I just seem to be piling on the weight. I have put on about 6 pound in the last 2/3 months. Any help or ideas would be great as nothing seems to be working and I'm not sure if I should be worried?
