"the key to using alli is that you must list everything you eat and not exceed the amount of fat per meal.  i haven&#039;t experienced any side effects and am extremely pleased.  i lost 10 pounds before starting the program and hit a plateau, but since using alli, i&#039;ve lost 27 more with only 13 pounds to go.  when i reach my ideal weight, i&#039;m going to continue the tracking, eventually weaning myself off of alli, to be able to maintain my weight.  i don&#039;t expect a quick transition, but love the results.  i recommend trying it, but be diligent to follow the instructions for good results."
