*shrug* pretty hard to stop eating when you are surrounded by food and are HUNGRY.
She’s not eating from hunger....she’s eating that much out of habit.
In nearly all cases where a person is greatly overeating even though only eating when hungry, the hunger is the direct result of a habitual diet of sugary, starchy, and calorie-dense foods. Some of these people who grow up in families with poor eating habits simply have no idea that eating a big salad will leave you less hungry an hour or two later, than eating a big pile of greasy pasta with 10-20 times as many calories, because they’ve simply never experienced it. They’ve grown up in families where “salad” means things like mayonnaise-laden potato salad with a few scraps of shredded carrot for color, or a concoction of marshmallows, fruit chunks canned in heavy syrup, and nuts suspended in a mountain of whipped cream.
