If a person weighs over 1,000 pounds and is totally bed-ridden, how on earth do they manage to continue consuming the enormous amount of calories it takes to stay that heavy?

Just saw a blurb about a “half-ton woman.” She can’t get up to go in the kitchen to get her own food. She can’t go to the grocery store. She can’t drive. She can’t do anything for herself, so someone is obviously bringing food to her. The woman can’t force that person to bring her food. Doesn’t that individual bear some responsibility for the woman’s weight issue?
