Yes, but you have to remember....
that for some people, this is what works. Some of us are truly carb-sensitive. And if it helps us to monitor the carb intakes, then why is it considered extreme or unhealthy? I eat a very balanced diet. Plenty of veggies, fruits, etc. I just like to control the carbs--works better for me that way.
And I also live in Asia--Okinawa, Japan--so I have seen what type of diet Asian people eat. Yes, they eat lots of grains, but (here, at least) the other staple is fish (especially raw-ick) so they're getting plenty of low-fat protein in their diets as well.
If something different works for you, then that's great. I'm just trying to share my personal experiences; everyone's body responds differently to different things.
