I am getting married in (almost) exactly 3 months...and I'm hopelessly discouraged. I've never been significantly over weight, but I wanted to trim down about 15 pounds. I started working out & dieting hard core (1 hour a day of cardio and lifting, eliminate heavy carbs, sweets, etc.) 2 months ago...and decided not to step on the scale until I was in 2 months. Well today was the day...and I GAINED 7 pounds, along with my clothes feeling TIGHTER! What am I doing wrong?! How can I shed the 15 lbs in 3 months??? Tips? Advice?
