I don't know about yasmin or dairy products increasing weight loss. Only recently have i been able to loose weight on yasmin (I am currently off of it now), and I think that was mostly due to starvation b/c it hurt me to eat everything for awhile with my teeth problems I have had, even soup hurt. So, I lost weight. I too was on Alesse and I gained 30 lbs in my 2nd year of use so I switched to yasmin but have had other negative side effects not related to weight gain, though I did go up in weight even more the 1st year on that pill. Some women may be able to loose weight on this pill and others just won't, it just depends on you.
