i have been on the fat metabolism now for 2 weeks and the only thing i noticed is that i am doing a lot of burping which i hardly ever do. let me know how it works for you in the comments section below. i'm 6'2 and don't like hitting my head so i build them a little taller. only downside, they were about a half an hour late but called to let me know they had truck problems. for whom would this possibly be an issue? because it has cream cheese, so it could be called a cheesecake.
