My guess would be that it's people drinking diet soda, salad dressing, sugar+cream in their twenty coffees before lunch, and/or bread. It's entirely based on my experience with folks at the office. I, myself, don't eat breakfast for anxiety / gallbladder removal reasons (I also don't eat lunch when I'm not at/close to home for it), and my fat ass is from a horrid soda addiction as a kid.
Sugar and related carbs really is the worst, eat whole plate of baked potatoes and meat, sated for the rest of the day, eat the carb equivalent in pastries and brain is still in "want more" mode...
