why do i only want to eat bacon?!

From a physiologic point of view, every human being loves food high in fat content. Its normal. But as rational humans, we can decide how much and when we eat these foods.

So you can be like everyone else and suffer because you cant eat all the bacon in the world and still be pretty, or, eat to your hearts content until your heart decides to call it quits =P

Is this a new development?
Maybe theres something in it that your body's really craving like salt, iron, protein and fat.

I go through phases too where i want very particular things...i went through wanting pizza and a chocolate milkshake ( i never got my hands on it however but i constantly fantasized about it)...curry....Lemon based deserts (it had to be cold lemon ??:$)-i never quite found what i was looking for exactly. (Closest was a lemon based ice pop?)
Those were the most memorable because that was all i could think of that would satisfy me.
Lately i went through something of a potato phase..where i'm practically infatuated with them...a month or so back...all i wanted was banana morning noon and night..LOL. Today however i'm all about the chocolate unfortunately..i'm going to pay for this i know it.
Strange. :@
I think maybe to force yourself to eat different flavors may be important as it may be some kind of imbalance in your system.
I've heard it said that what you do it...you end up craving.!
Best of luck.

Because its sooooo freaking good. If it didnt have so much fat and bad stuff i would eat that all the time. So as the rest of the fattening unhealthy yummy foods. If they didnt have such high far content wouls be eating those all the time too.

Because your Homer Simpson
