when i run into anorexia i drink coffee like its water....according the nutrionial value its only like 1 calorie ....what makes coffee really not good for you is the amount of sugar you put in it and cream...normally i will only eat around 2 to 3 bananas and a few coffees as it is a laxative and an appetite decreaser...but i do allow myself two tsp of sugar since bananas are 121 calories ...plus bananas decrease appetite as well..and by the end of the day i only intake like....263 calories...not too bad ....
