I can't recommend fasting enough. I do rolling 72-100 hour fasts to lose weight and its by far the easiest thing to do. Are you familiar with water? Yeah. Good to go. (You probably want to add in a bit of sodium/magnesium/potassium)
Yes the first day and last bit suck, especially the first time. But its also ~3-5x more time efficient than most calorie reduction diets and you save time and money.
