All I can say for me is that when I started low carbing to deal with my own medical problems I started to lose weight and feel great.
If I start eating high carbs again I get cranky, irritable, my symptoms return. Listening to the "experts" in the 80's about nearly ruined my health.
Everybody is responsible for their own health. If low carbing doesn't work for you then fine, find what does work for you and don't worry about what everyone else is doing.
However, I prefer a good cut of steak, small salad with olive oil and vinegar, broccoli with butter and a dessert of sugar free cheese cake with fresh strawberries over tasteless fat free fare any day. JMHO
