Welcome! You are at a great place, at least I got addicted right away and the charm never went away!
I am afraid I can’t help much with your questions as I have no social life and I don’t really do snacks. I am hungry, I probably eat red meat and whatever else I have and fancy. If it’s a super rare case when I truly just need a tiny bite, it’s usually the same but in the past I had some meals consisting from a boiled egg or two and maybe some cheese… Boiled eggs are useful, they may come handy as they are but they can be used in more complicated dishes as well (egg stew is popular here).
I don’t know what is the afternoon slump, I do have a lowered energy level but it’s after a substantial lunch
You can find meal ideas in many threads (enthusiastic people often post their last masterwork) but a notable monthly one is the “food pic thread”, it has the name of the months in their name. And “boring keto” too, I suppose it’s a joke as it’s definitely not boring for us most of the time, there are so many options, after all! I know some people find carnivore plates boring though. They are not in my eyes but indeed, it’s often brown, sometimes yellow, white or red but not really green (well if one is relaxed for some cheddar with pesto but I didn’t see that from anyone yet )…
What style of keto do you follow currently? What usual keto items you don’t eat? That can help with advice.
I think a steady energy level is what a body should do when it’s well fed, it works for me with a 1-3 hour eating window too but of course, maybe some people need many meals during the day. Probably the ones who eat small ones? Or get hungry very early? Tiny meals are easy, I mentioned the eggs but any kind of nice protein, with vegs if you fancy them, maybe some nuts… It’s quite individual. Nuts can’t satiate me but they work for some people for sure. But they can be just some little extra. Some people use fat bombs, they can be savory, sweet and neutral…
Best wishes to realize your goals with keto (and more. I got some benefits I had no idea I can get. it was with carnivore though)!
