Welcome to the forums.
Iām sorry you are feeling overwhelmed, but as other people are posting, the key to keto (catchy, huh?
) is keeping your carbohydrate consumption low enough to keep your insulin level low. Protein affects insulin too, but at a lower rate. Besides which, we have to have some; itās essential. But you donāt need too much, either, so keep it moderate. Thereās a lot of wiggle room with protein, so just think āmoderate proteinā and relax.
The calories youāre no longer getting from carbohydrate? Get them from fat. Yeah, fatāisnāt that a trip? But fat stimulates insulin the least, so itās the safest source of calories. So eat plenty of fat, enough to allow you to go for hours between meals without getting hungry.
ETA: You can measure glucose or not, whichever you want. If measuring is going to make you crazy, then donāt; itās not required. If you keep your carbohydrate under 20g, that will practically guarantee you low glucose, and therefore low insulin levels. Most people find it easy to stay under 20g by avoiding sugar, starches, and the like, and just eating salad greens (think blue cheese dressing, yum!) and fibrous veggies, such as broccoli and cauliflower (more cheese, yay!). There are lots of curlicues you can add, but if you want to keep it really simple, stick to bacon and eggs for a while, then branch out when you feel more relaxed and ready for some adventure.
