you are probably gaining muscle, and unlike her you are gaining a toned body while still losing weight.  Muscle weighs more than fat, so you may have lost more fat than your friend, but you have gained muscle. I wouldn't be too concerned about what the scale is saying for you until after the first month--what really matters is how you feel and the inches being taken off. Also, I thought I should just add that I lost 85 pounds on weight watchers and I didn't do more than my normal exercise-- 30 min. 3 times a week...and that took me about a year to get off. Also, don't push yourself too hard, if you keep exercising all the time and eating a little your body is going to eventually get used to that, and then exercising less and eating more than the little that you do eat will cause you to gain weight. Weight watchers is all about GRADUAL change--the slower you loose it, the less time it takes to get put back on. :D hope this helps <3
