There seems to be a real aversion to changing the diet, even if the diet you're going to change to is one you've enjoyed in the past. Once I'm on it, if anything I enjoy a fattier, more protein-controlled version of low carb more than a less ketogenic low carb diet, but there's still this inertia about the switch. Increased palatability, increased energy, increased ability to function around people, not as big a dietary switch as from a high carb diet to Atkins, but still there's that reluctance.
