I would 2nd bsc’s recomendation of Gary Taubes. Why We Get Fat is more for a general audience but is based on science.
There are no nutrients in grain that you cannot get from meat, fish, nuts, cheese, and non starchy veggies. Many of us find that whole wheat etc. still cause major problems and must be eliminated. You will also find many here that eat slightly more carbs than Dr.B recommends and are still able to meet their goals.
T1s find they use dramatically less insulin so they make less errors an can gain tighter control. T2s remove the source of their blood sugar spikes and thus gain tighter control.
Check out some of the old threads in this group to learn how different people have adapted Dr.B’s principals and by all means read the book. By the way this group is also a great source for low carb recipes, you’ll find you don’t have to feel deprived eating this way.
