Speaking as someone who's clinically obese, I think everyone but the most extreme use that high level of a heuristic. 3 pizzas a day is way too much. As someone who's tried to lose weight (with on and off success) for years. Once you are in this place, you have to apply much tighter heuristics. Your body isn't giving you the right messages about food. (e.g. Can I have 3 slices of pizza today, is this salad actually lower calorie than that slice of pizza, which one will make the rest of the day easier.) Your body dopes you with Serotonin every time you eat. trying to lose weight has many withdrawal like aspects to it.
