Just don't. Best case, you'll make yourself sick. Worst case, you won't get sick. And so you'll eat more fries. Success is not guaranteed. Surgery truly is a tool. I know 2 people personally who have gained back a large percentage of the weight they lost by not following the guidelines. So, just don't.
Even so, these first few weeks are the WORST! Liquid diet is awful. It seems like everyone you seeks eating your favorite foods. You're tired. Hungry. Sad. I used to cry in the shower after my family had dinner.
It is ALL worth it. All of it. So, hang in there. Remind yourself that this diet is temporary. The sadness is temporary. The cravings are temporary. It does take a long time to be able to eat real food, in a reasonable serving size. Still worth it.
Plus, those foods are only good HOT! By the second bite they're kind of greasy and gross. So, door dashed fries are not worth your tears
