If you're talking about the chicken taste, quite frankly, I have no damned idea.
Well, it's rough if you don't plan for it. Protein is great because it converts to energy slowly. On rest days, you want to
try to get 1g of protein per pound of body weight. Or 3g per kilo if you wanna do it that way. Also, you want to basically balance your intake like this:
Mine:
Rest days: 53% Protein, 23.5% Carbs, 23.5% Fat = 1533cals.
Workout Days: 41.2% Protein, 44.1% Carbs, 14.7% Fat = 1971cals.

A 16 hour fast isn't as hard as it sounds, since you're (probably) asleep for at least six of those hours anyway.
Also, calorie free things are fine. Coffee/Tea with Splenda, diet soda, water, gum, celery, etc. Some of these help to fill you up to continue the day without breaking your fast (much). Remember, this is a fast for health reasons, not idealogical.
