Butterfasting is the best way for teenagers who troll pro ana boards to lose weight.
The butterfast is amazingly simple. All you do is eat a stick of
butter in the morning (can be melted or nonmelted). For the rest of the day, you can basically eat whatever you want until the
butter passes through. It seems completely illogical, but the
butter doesnt
lie.
I think it coats your stomach or intestines (you know, the part that absorbs the calories?). And the food just passes right on by.
Warning, the butterfast does have a slight laxative effect, but butterfasting is much gentler than laxing.
