They're using high-calorie processed food for the dopamine rush it gives them. They don't really taste food like we do, they can't. Tongue receptors burnt out from high fat, salt overload, refined sugar. Blood glucose whipsawing out of control on a daily basis due to insulin spikes. When they are crashing they're no different from heroin addicts jonesing for a fix. Ever seen them get angry when they're denied food? It's like a junkie having their stash taken away. Pathetic.
