I am coming in really late to this thread. If I had to choose, I’d say to concentrate on the “Newbies” category on this site. Also, another fantastic site is dietdoctor.com. They are offering a 30-day free trial. They are a not-for-profit and are totally legit. Put a reminder on your phone to cancel your membership after 28 days or so, and you won’t hear from them again. No spam or any other junk. This will open up a lot of free content to you that is scientific, completely understandable and relatable. When I started, I just drank it in.
Before keto, I never “cooked,” nor did I want to. My husband and I are past 60 and do not have children, so it wasn’t a necessity. Pre-keto, we’d have whatever junk we wanted to throw together for dinner. It was delicious (as junk food can be), but was killing us - especially me.
Anyway, it sounds like you are a busy person. When just starting out, I did three simple meals a day for the first 3-4 weeks, although I had never done so before. I don’t mind eating them same things over and over with little variation, and that was a tremendous help. Breakfast would be 2-3 scrambled eggs in butter with one or two pieces of bacon or sausage, and coffee with a splash of heavy whipping cream. Lunch was whatever I could throw together - romaine salad with chicken, home made blue cheese dressing (simple), hard boiled egg, 3-4 oz. cream cheese. Dinner was always a piece of flash seared meat in a scorching cast iron skillet, (usually pork steak or pork chops with supplemental bacon grease or ghee, or a couple of hamburgers [73/27]), with steamed brussels sprouts with salt and bacon grease or ghee. (Yes, you can eat like this and lose weight.) Always delicious. If you don’t tire of things easily, this will save you a ton of time and toil. After 3-4 weeks of eating three meals a day, my body naturally said “enough,” and I went to two meals a day with no problem whatsoever.
I was terrified in the beginning and didn’t have much of a clue what I was doing, but I listened to people here and did what they suggested. Main think is, eat, keep the carbs as low under 20/day as you can, and meet or slightly exceed your fat and protein macros each day. There is a free macro calculator on ketokarma.com (at the bottom).
