Unhealthy underweight people (this is partly genetics and a little lifestyle... the problems I have, parent has, also another poster mentioned her dad having the same problems).
Healthy overweight people (partly genetics to them being healthy).
This is also very true with Psoriasis people and other health conditions (although not EVERYONE does get psoriasis).
But not forgetting that a underweight or overweight, healthy or unhealthy person can develop in their lifetime a new set of health issues without genetics being involved and lifestyle being a factor (basically say if your parents had good genetics from their parents whom were healthy, they developed these problems SOMEHOW in the course of their lifetime and left it to burden their children (kind of like HIV infected people do)).
But like HIV infected parents do, not every child is effected.
I have read peoples Arthritis being healed from fasting and/or raw food. From what I've read so far, confirm me if I'm right or wrong (chrisb?) that Arthritis is a cavitation on the joints, a missing bone fragment on the joints. So basically a whole new bone regrows or straightens.
While this can happen to people with arthritis, it does not happen TOO often (although does happen) with people whom have tooth problems (toothbrush+toothpaste pretty harsh... i tried brushing with toothbrush alone once and it hurt a lot!!). Plus your teeth also intake minerals (as well as the things next to the teeth) very, very well (why oil pulling is so good for people). Not good if you're putting soap, fluoride, baking soda or any of that stuff on your teeth (or near your teeth, basically its in taking in your body a load of crap).
Raw food gives you time to maintain a base of body weight, while giving your body a break from extra calories and food that is hard to digest, to give a break for the body and have your body heal itself, then eat again, heal itself, eat again, heal itself, etc. That's why it takes quite a long time for people to see results if ANY on raw food.
Anorexic people eat in very small amounts throughout the day or at one time, basically the white blood cells or whatever goes into your body to heal, go into your stomach to digest or help with digestion (or are constantly interrupted), through this course, your body cannot heal or repair.
although could be a contradiction to what I am saying on raw food?
By the way, I think the hunger feeling is your body's white blood cells working. I think people like to eat a lot, because once they eat, your body cells go straight to the stomach and you wont feel anything (or much if anything). Once they stop, their cleansing out in huge numbers on the stomach, the lungs, the head on mucous, stones, excess fat, etc. Once they finish that, they move onto the body healing and at the end stages repairing/constructing.
