Razzi, the Atkins diet has been around for quite some time. I first learned about ketosis when investigating the dangers of that particular diet. I agree with what you say, but really, a healthy diet is one that includes carbs as well as proteins, and is well-rounded.
My dietary research started in my early 20's, when I found out I was not metabolizing minerals properly. Since then, it has been a lifelong exploration and study of nutrition, and how it works. I'm happy to say that in my 50s, I still have the same size 5 wool worsted suit that I bought when I was 22, and my system works better than ever.
If it comes from a pig, I love it! mmmmm,,,, bacon! And I don't cook a ham too often, because I tend to have it half-eaten by the time it reaches the fridge. Though I don't eat a *lot* of meat (ie, portions are small), I do have a protein every night before I go to bed; otherwise I wake up sick and hungry.
Beans and legumes have been a real life-saver; as a type 2 diabetic (who takes no meds), they provide complex carbs and proteins, and help to stabilize the glycemic index. Inability to eat any grains whatsoever has made me a constant eater (protein only satisfies for so long), and of course, fructose is quickly metabolized, so that means my fruit intake (except for avocadoes) is limited. Potatoes, as someone said, are night shades, and also are not good to have too often.
Oy, the challenges of a special diet! It's all worth it, though, to feel healthier.
