Why not just cook? When you get good at it it doesn't take very long and you said you're not doing anything anyway

Can't speak for op, but boy do I hate cooking.

what about it do you hate that you would spend $35-$50 and apparently an hour per every meal avoiding it? Eg if you were the op.

or just answer for yourself... what do you hate about it?

It just seems like more work. The amount of time buying ingredients, cooking the ingredients, washing up after cooking in order to eat a meal seems out of wack to me. So I always end up cooking more for myself than I should because ultimately I'm sitting there thinking "there's no point going to all this effort for a tiny amount of food".

But realistically that's not what happens, I just end up buying a lot of store sandwhiches and takeaways instead.

Cooking to me seems like a hobby some people really enjoy or at least competent at, if you've got no interest in that hobby then it's easier to just swap money for food directly instead.

Is it a practice thing? My mom tricked me when I was a kid. I really liked omlettes. She plopped the Julia book and the tools and ingredients in front of me and I basically cooked omlettes for 2 hours till I got good at it and ate them. She did that for several other meals letting me perfect my technique.

Since then I've always been good at cooking as it holds no fear for me and makes sense.

That's true. The high order bit here is really the keto diet. There aren't many restaurant options that are compatible with keto, especially desserts. The time savings is a nice side-benefit, but isn't the main driver of the decision.

How does any dessert is compatible with keto?

Keto is basically just low carbs, low sugar. You can make a lot of good desserts within that limitation. Dark chocolate is pretty low carb, as is cheesecake.

Milk is practically all sugar. Doubt anything with sugar can be remotely considered keto.
