Welcome! Glad to have you here, and doing a HAPPY DANCE that you actually were COUNSELED to do keto!! My advice is KISS - you know that principle!
Read the FAQ and check out the HOW TO topics for future reference, figure out your macros, then eat things you like, but add the fat you’ve denied yourself (or maybe you haven’t? ). Low carbs (under 20 grams a day). Moderate protein, then eat fat until you’re not hungry.
Dr. Sarah Hallberg, who runs an obesity & diabetes “resolution” clinic, tells her patients to remember “GPS” - no Grains, no Potatoes (or other root veggies), no Sugar. Fix your own food so you know what’s in it. Use plenty of salt! I ate an awful lot of bacon & eggs when I first started (still do!). Easy and nutritious and does a good job of fitting the macros.
You’ve come to the right place. It’s full of awesome, helpful people and inspiring stories.
OH! One more thing! ACRONYMS! This place is crawling with them, and the moderators don’t have any acronym spray, so they’ve become pets. I would print the Wiki & keep it handy at first. ENJOY and KCKO (it’s on the Wiki)!
