I went Vegan for a month and a half this year, I cannot tell you how much that changed not only my body health but mental health over that month and a half. I suggest everyone try it, I did the fasting thing also. I would stop eating at 9pm at night and wait till 1pm or 2pm the next day. Just a word of warning, there is a detox period up to 7 days, then after the first week you feel like a new person.
