how does one end up toothless AND 300lbs?? what the hell can you eat with no teeth that as the calorie base you need to bee 300lbs. not counting the super weight-gain 5000. BEEFCAKE!!
How about lard and ice cream. Cheesecake can be ingested without teeth fairly easily. Generally, however, the weight is usually gained before the teeth fall out. This means that one would only have to support the actual weight with a liquid or a paste type diet.
