Whilst it costs a bit more, you save so much time and possibly money. It allows you to not have any dishes -> no dishwasher needed -> no cupboard space needed -> no kitchen needed -> no fridge needed -> cheaper rent. You don't need to go grocery shopping (no car needed), food never gets wasted, you take out significantly less trash. There's 0 "mental load", you never have to think/plan about how you're going to eat/cook/whatever.
If you're willing to adopt a bit of an "ignorance is bliss" attitude, you can happily pretend that you're eating a perfectly balanced diet ;).
I have no affiliation with Huel, just an extremely happy customer. Now that I'm traveling around the world, it's pretty much the only thing I miss from my old life. If I could get it shipped anywhere in the world for a reasonable price, I'd probably still be eating it right now.
