if you want to lift something by telekinesis, you’d be just as tired, if not more, than if you used your hands. if you want to set something on fire by thought alone, you need to provide that initial energy somehow (like starting fire with bow drill). you’ll be drained just as much as after physical work
No, if you were just worried about energy, you would be much less tired than by doing things manually. For example, moving a heavy object downhill would gain you energy, not lose it, and keeping a heavy object in the air would neither gain nor lose energy. it would only be lifting that is hard, and it would still be easier than lifting manually.
Edit: and according to Wikipedia, human muscles only have an efficiency of around 20%, so doing basically anything through magic would be 5x easier than doing it by hand.
let’s keep conservation of energy, conservation of momentum, conservation of angular momentum and conservation of mass. who said telekinesis is 100% efficient? also let’s make it so that the bigger distance from user, the less efficient it gets
This is like saying you would be tired after lifting a pallet with a forklift. Many magic systems are about using magic in the world around you, which only requires you to understand how to use it; the energy being consumed doesn’t come from yourself.

Now you see why the people at Hogwarts have a big feast every other day. And I don’t recall the more corpulent ones using that much magic
