Do I have to do 16:8 everyday of the week, or is it still effective if I do it six days a week?

I am in college and once a week I like to go out. If I stay on 16:8 the rest of the week will intermediate fasting still be effective.Edit: I do plan on eating healthy regardless if I am doing 16:8 that day, it’s just going out will be outside my normal eating window. via /r/intermittentfasting http://bit.ly/2VfY609 https://ift.tt/eA8V8J
