A cheeseburger has enough energy to power you for most of a day. Possibly doing a lot of heavy lifting, and continuously running the largest and most sophisticated neural network hardware on the planet.

That'd be a very large cheeseburger. I burn more calories in a typical 50 min workout (weights, not cardio, it's easier with cardio.)

Looking up burgers I've eaten recently:

* A bacon cheeseburger from Five Guys is 1060 kcal

* A double-double from In-N-Out is 670 kcal, and that's before you make it animal style

But yeah, not a McDonald's cheeseburger. I'm somewhat offended that they're allowed to call those "burgers".

A 300 kcal cheeseburger? I don’t think so. The baseline metabolic rate of an adult is ~1700 kcal/day.

The definition of a dietary calorie (kilo-calorie) is the amount of energy needed to raise the temperature of 1kg of water by 1 degree Celcius.

So the kettle math is actually quite straightforwards.

Yeah, I mean, it's just generally astounding that the food I eat is enough to power even a sedentary lifestyle, let alone one with a bunch of running and other exercise.
