My partner and I started June 1 - first time for both of us. We're "secretly" doing it - meaning, we are not telling anyone we know until we complete it (which I know we will). This is to show that we can be healthy without having "excuses" (sorry I'll pass on that doughnut, I'm on a diet, as opposed to: no thanks, I'll pass!). However, I felt I should share with the community here!
Day 4 and I'm actually feeling the same - which is pretty great. I feel like I am getting plenty of food, and the biggest change is the planning aspect. When I was feeling tired, I noticed exercise helped pump me up again. In addition to the Whole30 restrictions, I have also excluded coffee (which I don't drink, but my partner does. I think kicking a caffeine habit is important, too) and any clarified butter or ghee as I already didn't eat dairy before this diet, so why introduce it now?
My sister completed this and felt very positive about it. She was a bit "preachy" which actually detracted me at first. I thought I'd give it a shot, though, because I definitely have a sugar habit to kick! Ultimately I'd like to stick to primarily paleo diet.
Good luck everyone!
