Weight Loss

I was asked to participate in Weightwatchers. My friend started it and asked me to join also. I did two weeks ago. I have lost weight. My starting weight was 175 pounds. I am sharing my weight because it will not be this much for long. I am now at 170.8 pounds. Weightwatchers is teaching me how to choose more wisely the foods that I eat. It is hard because I love to bake and cook and low fat and fat free where not in my vocabulary. I have been working a lot lately, but it is for a good reason. Working makes having time for exercise a little more difficult, but I need to try a little harder I guess. If anyone has ideas on how to work out while also working 12 hour night shifts please suggest away. I need it!
