Yeah, travel would be really hard. We didn't go anywhere more than a night when we were on. You would have to pack food to do it successfully, but yea keto is best when you're fixing most of your food.

That's the optimization problem. I find one can't always have it all. Sometimes health means have a less than delicious meal or skipping a restaurant.

When I'm on my deathbed, I'm far more likely to regret the things that I did eat opposed to the ones I didn't

I actually think this is an important part of cultivating healthy relationships with food. I needed to stop thinking about boring meals as missed opportunities for consumption.

I mean, there aren't great choices at Sonic, but it's not too hard to find a burger at most restaurants, and a steak at the ones that don't (and just don't eat the bun).

A diner breakfast of eggs and bacon or sausage will do as well. Just don't eat the starches.

I'm much less strict now than I was, because I am comfortable going into ketosis and losing a few pounds if my clothes start getting tight. But in the beginning, I aimed for 10 g of carbs, assuming that due to wrong estimates and "hidden carbs" (anything with less than 0.5 g per serving can be listed as 0 carbs) I'd still likely be under 20 and definitely under 40.

Some would say that's not a varied diet. I would argue that eating a different dessert at every meal isn't all that much variation except in taste - which is not to be laughed at, but I've always been the kind of person who would rather have more steak or hollandaise than a dessert. Poached eggs on ham, covered in hollandaise, is not exactly an ascetic diet.
