1. I'm more of an independent observer when it comes to the various types of diets, and that's mainly because I've found what's good for me through trial and error. That includes how much I need to eat and how frequently, as well as whatever ratio of the food groups that ends up being. Frankly, I have no idea what that ratio is, and it won't be helpful for me know what your ratio is ... our bodies aren't equivalent.

2. The idea of ketosis as a form of sustainable energy seems rather ridiculous to me. I'd equate it to pedaling a bicycle with your hands instead of your feet, forever. Human metabolism is a tuned machine from a biochemical standpoint. The Krebs/TCA/Dark Cycle nets 36 ATP, whereas anaerobic metabolism nets 2 ATP. When it comes to ketosis, you're not limiting the oxygen to force the switch fermentation, but ultimately achieving the same end result through another much less efficient pathway of lipolysis. If you're a sedentary being that only needs his/her body to work extra hard just to support the brain and liver, that's fine. If you want to have an active lifestyle and maintain muscle density, it just doesn't make sense as a sustainable diet.

3. Not to be picky, because perhaps you were completing it mentally, but some of your logic is flawed. You say "Indeed, people on low carb diets have seen the LDL lower and HDL raise" ... but it's not the carbohydrates that are impacting the levels, it's the increased fiber and reduction in saturated fats that give better HDL/LDL levels. And yes, you can have a low-carb diet that's high in fiber and low in saturated fat. And the rest of your arguments follow the same (1) here's my point (2) evidence that sounds good but doesn't directly support and/or isn't specific of my point (3) [insert contemptuous comment about the AHA]. Yes, you can get vitamins from other sources than fruits/vegetables ... at what sacrifice to caloric intake or health (e.g. you may have to eat 5 lbs of red meat to get the equivalent amount of vitamins in a cup of veggies)? Yes, Jack La Lanne ate meat, but he also consumed thousands of calories of carbohydrates to sustain the strenuous workouts ... no active person/athlete/body builder could do it otherwise.

4. I thought AHA was a band from the 80s ...
