I have noticed this too, and I concur with your conclusion. I've only been watching Amberlynn and Chantal, but I have noticed the following:
1. Neither one knows how to handle a knife when prepping food. They chop things half-assedly into big chunks and throw them into a pot, as if spending an extra two minutes to cut things carefully is just too much hassle.
2. Both over-rely on frozen processed foods that require no prepping
3. Both prefer to eat out than prepare meals
4. Neither one knows how to hold a fork properly.
5. Neither knows how to cut things on a plate in front of them; they both use a babyfisted stabbing motion to cut, as a 4-year-old would
6. Both drop bits of food all over themselves when they eat, where it gets lost in rolls of fat. If they pick it up with their fingers, it goes in their mouths.
7. Neither are self-conscious about wiping their nose on their food and salivating at the aroma
8. Both will put single bites in their mouths that really could be three bites.
9. Both will resort to eating with serving spoons
10. Both produce unappealing, brown slop when they cook.
One would think that a 400-500 pound person would have the art of eating down; what else could they know? But this is a mistaken assumption; food has no art to them. If they could get away with using funnels, they would.
I've tried to imagine what causes such appalling behavior, and I keep coming back to two things. Intense laziness makes them too impatient to wait for food to cook, and a weird pathology of needing to feel stuffed or they can't feel sated at all makes them gobble the food down so fast they can't even taste it.
I've always thought deathfatties were gross for obvious reasons, but getting to know these two fat-heads has really shown me just how awful a deathfatty lifestyle is. If laziness were a crime, both of them would merit a firing squad.
