Hi, I'm new here. I've been cycling for about 5 yrs. and recently, I've gained close to 40lbs. over the past year and a half. I haven't changed my diet (I try not to eat dairy, sugar and red meat) and I run at the gym for an hour plus do a 45 min. weight routine. I cycle 10-20mi./2-3 days per week. I just put my bike on the trainer for the winter. I'm ready to throw in the towel, because no matter what I do I either maintain my current weight or gain. I used to weigh 95lbs, now I'm 126 and 5'1". I really find it hindering my cycling performance, not to mention I look awful. I had my thyroid tested and all the routine blood work is negative. What can I do to reverse this, am I doing something wrong or leaving something out?
