The primal approach to diet speaks to eating as many earth grown nutrients, and eliminating processed foods. Ive lost nearly 30 lbs and gained 12 in muscle but I have also been training aggresively.

You guys want to hear some knowledge from experts in the field. Mark Sisson. Nate Miyaki. Mike Dolce. These guys deal with elite athletes from MMA to MLB to IFBB athletes, and then normal fat business people who dont have 'time' to take care of themselves.
I myself am an ex pro athlete, and also work as a fitness professional and until I completely embraced a sound diet protocol it was all for naught. Surfing. Better. Training. Way better. Headspace. Through the roof

Any white or processed foods promote inflammation, hypoglycemic rebound, and a litany of other crap that in the long term can kill you, in the short term make you less of yourself. I was 243 at my worst and 21% bf now 216 and 10.8% bf, and its mostly diet. Truth is its 80% diet which any qualified CPT and nutritionist will tell you...

Dolce and Narte both speak to cheat or earned meal days which are important, also about intermittent fasting. Amazing stuff. PM if you want some reading about Nate he is really on it. Mike is getting famous and his stuff is all over the internet.

Good Luck
