<human>: My brother-in-law is anorexic, he lives with us & we are taking care of him because he can't take care of himself. I make him healthy, beneficial food. He'll eat 2-3 mouth fulls, put the food away then proceed to eat junk food. To which he complains about lack of energy, he believed he had chronic fatigue due to lack of energy (he doesn't btw). I have explained the difference about processed vs. raw foods & why he would be more compelled to go for the junk food. He explains that he feels full & that his bowel movements are stagnant so he drinks copious amounts of coffee for bowel movement. His body has now become dependent & now can't do it naturally. Dieticians, I need a weening alternative to get rid of coffee in our household. Please help.

Can you give me the gist of the text in a nutshell?
