"i think most people expect changes in body too quickly. i have been on alli for three weeks i am down 4 lbs. i am eating smaller meals and in a consistent exercise plan. i never expected alli  to make me rock hard after a month. i plan to use for 2 months to help kick start my second 15 lbs.  alli works if you follow restrictions not going to work with an extremely fat meal. this is supposed to supplement a new life style change. if i only lose 3 to 4 pounds more i will be happy. i am not expecting alli to work after 3rd month. i have 6 more pounds to lose before vacation and another 8 to 10 this year. the lesson is you still need to watch how much you eat. you also need to be active 3 to 4 days a week period.  15 lbs this year and 15 next"
