you cant eat the same thing long term, you will become bored with it, don't set yourself up for failure and just eat a wide range of paleo foods

I certainly think it will be more complete than just KFC and chocolate.

I think it would help if the chicken breast included the skin.  I'd also add wings if you eat them.

 I`m no dietitian but  I`m curious about what kinds of veggies you eat. Avoiding fruit is one thing but you should compensate by adding different, nutrient dense veggies.

 How about berries......adding frozen blueberries would be a good(year round)choice and, when in season, eating a full range of fresh berries would be healthy, paleo and tasty.

 Long term I think you need to make sure the body is getting all the nutrients/vitamins/antioxidants and fiber it requires. I also think it`s important to balance your body`s acidity/alkalinity for maximum wellbeing.

Having no knowledge of how long you've been doing any type of Paleo, that diet could be very useful or potentially detrimental. Honestly, the plan itself isn't bad. It looks like you'll be getting a fair amount of fat. However, be aware that if you're having to eat bags-full of nuts each day to stay satiated, your body must be searching for more fat. By far the most important part of that diet plan (given that it doesn't appear to include any cheats) would be satiety IMHO. Of course, if you begin to deviate from the plan due to insufficient satiety, you may find yourself back at KFC... In which case, I guess the best thing to grab might be 1 of those sandwiches with no bread!   -I've never had KFC and in no way endorse it, but i've seen the commercials recently...
