Yeah, you absolutely don't need to overthink keto once you have a good idea of what foods provide the ideal set of nutrients that you need. You just have to keep those foods stocked, and eat whatever you have on hand when you're hungry, until you stop being hungry. As for avoiding junk food, just STAY OUT OF THE JUNK FOOD AISLE. Don't walk through there, don't daydream about chocolate, make a conscious effort to keep it out of sight, and it will be out of mind. That part takes some self-discipline, but once you make the conscious decision to keep it out of sight, your mind will go wander to some other distraction or stimulus and you will forget about it, and it will become a habit soon.

The truly hardest part of all of this in general is finding a suitable form of substitute stimulus that keeps you from being driven to seek your default vices. The unfortunate part is that there are not a lot of accessible/healthy things in life that provide the adequate stimulus that we seek/need in order to feel "okay". We're drawn towards drugs and junk food and etc because it's easy to acquire and satisfies our needs for stimulus in the short term.
