I think it sort of depends on how you look at it. If 800 is an hour of running - that's probably "a lot" for quite a few people. But 800 is also just a sandwich. Which isn't all that much.

So if you view this from a time use perspective, just skipping that sandwich is way better than running for an hour. And many people can't spare an hour a day just to make up for a sandwich. Hence - "not a lot" - Its too expensive time-wise for the caloric balance effect it provides. Just skip the sandwich instead.

What kind of sandwiches are you eating? 800 calories is a ridiculously large sandwich.

Even Tesco's bacon & egg triple is only 550 : https://www.tesco.com/groceries/en-GB/products/260422235

I'm struggling to find anything I'd describe as a sandwich come close to 800 calories.

Footlong Spicy Italian at Subway ($10 sandwich) is 1320 cals.

EDIT: the trend holds pretty well at the footlong size (which is a big sandwich). 18/26 sandwiches they offer are >1000 calories.

Fair enough, but so is 800cal/h exercise. And I'd rather overestimate the intake.

I agree with the general message, but I'm curious what ingredients go in your 800 calorie sandwich. That's more than a double Big Mac with 4 patties (780 kcal)!

Maybe the Elvis sandwich

Lots of mayo.. and butter. It's more like a butterich, realistically. ;)

That's a big sandwich :)

Big Mac = 580 Cal.

I'm going to eat lunch one way or another and for me it's going to be under 800. Skipping meals isn't really a good choice, imo, but ok.

You need to eat roughly somewhere between 1300 and 2000 Cal every day to maintain your weight even if you are doing to exercise at all.

If you want to lose weight, it's far easier to remove 800 Cal from your diet, at least time wise, then it is to exercise 800 Cal's worth every day.

Either way, if you're losing weight at any appreciable rate, you will feel hungry (at least if it's not chemically induced in some way, such as chemo or GLP-1 inhibitors or similar). That's just something you have to get used to if you want to lose weight.
