Heres the general recommendation for starting:
<20g of carbs per day (minus fiber)
1-1.5g of protein per kg of lean body mass (what you would weigh if you have 0 fat)
Fat to satiety - that is, add fat until you arent hungry between meals
Try not to snack, but if you do try to make it as fatty a snack as possible like some keto coffee or a fat bomb - this is to allow insulin to drop as much as possible between meals.
Fats to try:
Lard
Ghee
Butter
Avocado, coconut, or macedamia oil
Fatty cuts of meat like bacon
Olive oil
Heavy Cream
Full fat cheese
Olives
Full fat dressings and sauces, curries, and soups
It is normal to initially lose weight and then stop for 1-2 months. This is normal. In this time there will still be noticable changes, like a less puffy face, less joint pain, visually smaller even if the scale doesnt move, losing inches… etc. Focus on NSVs during this time until you are fat adapted… or all the time. The scale frequently lies.
I have a thread up about moderate protein, high fat meals that I can link in a few hours.
Edit: also dont calorie restrict. Let your hunger determine how much to eat… trust me.
