How much?

This is just a reminder nag.

Set carbs as low as possible, protein at about 1 gm per kg of lean body mass, and fat controls the satiety duration.

Appetite is driven by fructose and glucose being consumed. Keep then near zero. Any carbohydrates being consumed should be complex fibre and starches, mainly cellular.

How much carbohydrate do we need... very little. Eskimos have zero in there traditional winter diet, except if they snag a piece of several varieties of  seaweeds, and caribou droppings, occasional Arctic hare first cycle droppings if they scare up the hare before they have finished. Note that the Arctic hare eats lichen, and then eat there own droppings, a two pass system, to get the nutrients out.

Fructose, glucose, and starch are caloric equivalent but metabolic handled far differently. Fructose is entirely nearly processed by the liver,  circulating concentrations are 1/1000 of glucose. Glucose mostly passes through the liver, and is circulated, where insulin drives it in cells that can handle glucose. Insulin resistance, aka, diabetes results when the cells are overfed. Insulin also controls storage of fats. Carbohydrates are absorbed at about 20 grams per minute from aquas solutions, while proteins and fats about 2 gm per minute, and from mainly the small intestines, each in there own section mainly. The large bowel allows bacteria to digest the food, and some is then absorbed.

Protein is mainly broken down in to peptides, and then absorbed. A few small proteins (gluten) can sometimes  slip in and cause problems. The proteins are recombined into what is needed or some can be converted to glucose through gluconeogenesis , along with any damaged proteins, glycerols, and some other stuff. http://en.wikipedia.org/wiki/Gluconeogenesis 

Fats are either stored or free fatty acid (FFA) is burned for energy.

Adrenalin and cortisol gets dumped to the digestive system when that are digestion problem, or demand for energy. This has some effects; we tend to eat when tired, stressed, frustrated, bored, anxiety  not because of shortage of energy, but because of excess adrenalin and cortisol. Not good for us who have food issues.

So go find a job you like that is peaceful, satisfying, easy, pays well, is close by to avoid commuting and computing, and carry on... if you can find such a thing any more...
