The protein conversation has been raging for years and years and will likely never be settled once and for all. The primal diet has become very popular also and you will definitely not have any problems getting plenty of protein on this diet. The primal diet outlines eating a lot of meat and vegetables the same way our caveman ancestors did. It does help you stay lean, as there is very little empty calories being eaten on this diet. Many people who do the 90 day P90X workout use the primal diet to get ripped. We also know many people who choose the 60 day Insanity workout and also get great results. When you are doing this workout that demands so much energy, you need to make sure that you are getting enough carbs to fuel your workouts. The jury is still out on the primal diet. It has as many critics as it does proponents, but it is very effective in the short term if getting lean and ripped is your goal.
