^So what you're saying is...fancy Latin terms aside...the law of thermodynamics still stands?

In all seriousness, nobody is saying eat a pure carb/sugar diet. That is an absurdum.

Nutrient macros are quite insignificant compared to caloric intake though. That's why the whole low carb/paleo crowd just doesn't get taken too seriously. They think they have a monopoly on fat loss, and it just ain't so.
