I don't know about the 9 months to get fat adaopted, , seems to me I get there fine in a week or so, but then again I've never eaten a lot of starchy carbs anyway. Now, you said your 50, so your only about 8 years behind me, and if you can remember, Vince Gironda had his bodybuilders on something similar back since the 50's. It was the same type of cycle, but 4 on 1 off. Might want to give that a shot if it's hard getting the 5 in. Personally, these days, I don't use any of the "diets" out there, but if I had to categorize, it would be closer to the Zone, Protein Power, or South Beach, somewhere in the grey areas in between. Lean meats, but no real worry about fat content as long as the cut is fairly lean, fish, etc, lots of fibrous veg, some fruit in the morning, limited starches, but I will mix in some legume with the veg, I just watch the quantities, and the fats; olive oil, nuts avacadoes, etc. Drink nothing but coffee tea and water (ok, maybe some beers at BBQs), no added sugars. Seems to work well for me.
