Well, I have been "surviving" and maintaining my weightloss on a high protein, SOME not high fat and lots of non-starch vegetable diet for years now. Still alive. In fact, I didn't even start getting close to my goal until I stopped eating fat beyond what my body needed. There are many ways to do low carb. A diet that is low in carbs is a low carb diet. Should someone find a way that works for them, more power to them.
I'm not hungry or in starvation mode/and I'm a smiling low carb success. I eat adequate protein, enough fat to satisfy (but it's not high fat) and plenty of veggies.

Peace
