why do i crave only the foods that make me fat?
bread, cheese, rice, candy...bring it on!
and why do i have no real desire to do anything to get fitter? i am usually ok with my size (16) but would of course rather be thinner and not wonder what´s going on in my arteries. and the scare tacts of heart disease and such just have no effect on me...why?

Hassia, we all seem to have a firmly-rooted conviction that we are invincible, that we will never die. That belief lives in the reptilian and midbrain, where the basic survival instincts reside: eat, sleep, shelter, protect loved ones, etc. I think it is there to keep us from fearing death to the point where we can't function. But the survival instincts are very strong and can sometimes take over the reasoning brain. I crave sweets and carbs and I like fat things because the flavor is in the fat. It takes a lot of willpower to overcome these cravings - do you have it, or can you get it somehow? It is also possible that you have some unresolved issues that are tormenting you and you eat for comfort. I do, too. You might talk to your doctor about it, if you haven't already. Go to your library and get a book on self-hypnosis. That might help. And good luck!
