I'm following Tosca Reno's Eat-clean diet. I haven't done Cooler 1 but have followed cooler 2 and sort of follow Cooler 3 on a daily basis.
I've been eating clean for about 2 months and it's one of the best decisions I've ever made! I have had the highest success on the scale yet (blame the holidays and not staying clean! and on starting a bit of weight training as well) but I feel and look a lot better and EVERYTHING in my closet is lose on me already
It's a great program and let me know if you have any questions, I've learned a lot over the past while!
