Low carb diets

I'm such a skeptic about diet and nutritional claims (because so many
are bogus) but am interested in this Low carb mania that seems to be
popular these days.

I notice that in the supermarkets there are new products touting
themselves as "Low Carb" with the insinuation that that will help with
weight control.

As I understand it, low carb foods tend to lessen the "amplitude" of
blood insulin levels which can cause hunger signals and consequently
cause a person to eat more. If that's true, isn't the bottom line STILL
calories "in" versus calories "out" or is there something else that the
low carb diet does?
