Do You Do Alternate Day Fasting?

I think people are so afraid, cause this is how i use to feel, just so afraid of gaining weight for any short period time. And especially if you're doing this for the long term, then this week or two or three that you've gained a few pounds, it means nothing when you're setting yourself up for sustainable life. Do you do alternate day fasting? I'm not doing it right now because i am doing seventy five hard. While i' never thought i could just go days and days without eating, but just how it helpsyou atd makes you feel....
