ELI5: Is there any difference between eating 10 cookies today and eating 1 cookie every day for the next 10 days?

Yes.  Eating a large number of cookies will add many calories into your diet.  Your body will be busy processing those calories and using them for energy as they come from fast-energy sources like simple carbs.  Other food you eat with fat and protein after eating 10 cookies will be set aside until the cookie carbs are burnt, and will lead to weight gain.

Eating 1 cookie a day is probably not a huge enough influx of carbs or calories and will be fairly inconsequential and not promote weight gain nearly as much.
