I dont feel like they are. Traveling France and Italy a couple years back, I found myself not finishing meals much more regularly that I do in the states, Even though I was eating a bit more because I was walking 5+ miles a day.

Maybe i was in part over ordering due to language, or menu expectations. Maybe some of thw places I was in were touristy and over doing it to match 'american portions'

But for instance, i got breakfast that was 'oefs en cocotte de compagne' at a café a couple blocks from the louvre, far enough to not be in the tourist trap surrounding area anymore.

It was massive- 4 shired eggs with a generous amount of mushrooms and gruyere, served with 4 pieces of toast. And I confirmed with the waiter that that was not a shared portion....

i walk 10 minutes (1.0 km) to the second-nearest grocery store (because that has cheaper and better-quality food) and i'm already living pretty far out on the city borders.

Fast Food!

Not being able to outrun your diet is a really strange concept to me, and I've exclusively heard it in this thread, and multiple times in this thread. Dafuq?

It's not that simple, if you are healthier with regular exercise your hunger is also better regulated and your diet will be better.

calories in, calories out. Use more than you eat and weight goes down. Eat more than you use and weight goes up. It's an oversimplification, but it's not wrong.

I mean, you can, but it takes a lot of running to expend the calories taken in with a pretty typical American diet, especially when you account for the increase in appetite exercise typically brings.

But it is possible. If you can burn 2000 calories on a single run, that's a lot of room to maneuver to fit your macros while eating a significant amount of junk food.
