Don't get yourself into a state where you need to lose 40kg. If you do, and lose the weight, you will have excess skin.
I like my new healthy self but actions have consequences.
I turn 50 this year and have committed to doing 50,000 pushups before 2024. It sounds like a lot, but after the first month, doing 200-300 a day isn't really that difficult (when broken up into smaller sets). Honestly, it's a LOT more of a mental challenge than a physical challenge.

Climbing up the stairs directly burns 2 calories, and not eating the Oreo because you're climbing the stairs avoids 53.
Sounds about right to me. Even if it does require living in one of those places where it is not customary to store your Oreos on staircases.
