DDH, when was the last time you had your thyroid levels checked?
Last summer I pulled out my Weight Watchers books and calculators to help me drop some unwanted weight. I also increased my mileage each week by 10% or more. I had to seek assistance here for help with the activities points awarded through WW but things quickly fell into place and the weight slowly came off as the summer months progressed. By the time I returned to school in August I had dropped 12 pounds. My weight stayed stable through the school year. This summer I have dropped 10 more pounds due to my surgery and having to deal with the fallout of my relationship ending and riding a lot. What I have learned these past two years is portions are very important, not to avoid the foods I enjoy but to enjoy them in moderation and I have to ride at least 6 days a week to maintain my weight. So since June 2006 I have gone from wearing a size 14 pants to a size 8 and I'm back to what I weighed when I graduated from high school in 1980. I love the new me!
Don't give up hope, keep plugging away at this. Pat yourself on the back. You will find a program that will work for you.
