The way they eat could be realistic

I see posts and comments all the time about how unrealistic the way the GGs eat being with how thin they are. Since I have a ton of work to do and have no desire to do it, I'll instead give my 2cents about a minor issue in an old teen drama instead.

Assuming they have healthy metabolisms, even with calories in calories out, it's actually realistic. They order a ton of food but then live off the leftovers. Lorelei says it several times in the series. Rory says in an episode that they always had leftovers in the fridge. In one episode they are even cleaning out their fridge and throwing away leftovers they think have gone bad. So they obviously don't eat everything they order. And lots of episodes where they are stressed or upset, they don't eat their food. They also leave food on their plates so they usually stop eating when satisfied. They rarely snack. They had easy to make food like beefaroni (Rory mentions it during one of Lorelei's tantrums) and mac n cheese (when Rory comes home from college she is seen making it), pop tarts, cereal and I swear I remember an episode where Lorelei is eating a salad out of a bag. They also eat at Sookie's, Emily's, Luke's, Al's pancake world and at town events. So they probably ordered the ton of food we see once every two weeks max. (They are very wasteful with food, that's for sure.)

They don't work out, but they walk a lot, more than the average person. They are also very high energy and are fidgeting, moving, participating in events and being active. They are always moving and walking.

So yeah, I think they could probably have eaten the way they do and been thin.

Thoughts?
