I'm still making small tweaks to my diet. I've taken out most processed sugers (except for occasionally some brown suger in oatmeal or a bit in tea), taken out most breads (except for sprouted grain), and gotten rid of most "bad" fats. I'm starting to incorporate some fasting principles but still trying to find the right balance and meal timing for my workouts. The goal is for function over form so even though a six pack is nice I'd rather have better performance. I guess you could call it a "paleo" type diet but it's pretty much the way I've always eaten. Lots of meat, lots of veggies. Now I'm just trying to dial it in to get the most out of it.
This week I will also start working with the Elevation Training Mask 2.0 which is supposed to simulate training at elevation. After a couple of weeks I will post a review. You can check the mask out at www.trainingmask.com
