I’m a low-carb’er without the high-protien mainly because the gubmint is promoting the conversion of corn into fuel instead of feed for livestock which drives up the cost of protein. Beef is danged unaffordable.
And I’m low-carb because it suits me. Plus the gubmint’s food pyramid love’s carbs and in my experience, you take the gubmint’s advice at your peril.
For adults who are not athletes, have a plan sized portion of protein twice a day (3 is ok too) and you’re golden. You don’t need a ton. Make two of the portions from healthy animals, fish, or dairy. One can sometimes be from veggie sources like nuts or seeds.
100g or so of carbs, and everythihg with a healthy fat alongside.
