carbohydrates and proteins in pill form would mean scarfing down DOZENS of pills three times a day, or one GIANT fucking suppository every morning.
even then, the lack of roughage would turn your digestive tract into a log-jam, and you'd need a crane to get the blockage out of your colon.
evolution has prepared us to survive on FOOD not pills, and even if all the nutritional elements were there, without the fats, carbs, protiens, fiber and the mass needed to keep that shit in motion, we would die.
even with enteral feeding under medical supervision patients waste away unless they can start eating again.
thats why theres so few fat coma patients.
note: this is not a recommendation for a weight loss regime, any more than catching the aids, or getting hooked on meth.
