Isn't abuse of OTC pills like this practically a given??

If you take a starch blocker AND a fat blocker, can you eat everything in sight and still starve to death? How about adding a "metabolism booster" so you can starve to death even faster? OR if you've had your stomach stapled, you can live on very small quantities of tostitos, ice cream, and M&Ms consumed throughout the day.

I feel sick.
