I am eating Keto and have been for 15 years.
Started back home and here for the past 8 years.
It is the best diet I have ever eaten and am in superb health at 75.
Key is to get rid of all starchy foods and eat fats instead. They are concentrated so only one meal a day is needed.
Proteins are cooked and must be free range. I am eating duck, duck eggs, chicken, chicken eggs, pork from local farms, fish from the sea and local rivers & lakes. Also NZ cheddar, home-made yogurt from local raw milk. Avoid all commercial pork & chicken.
Fats are NZ butter, sunflower oil, soya bean oil, palm oil, raw egg yolks. Bitter teas are drunk in the morning (black, oolong, jasmine), later in the day fruit juice, chocolate, coffee with added coconut milk and nut milks.
I eat about 75g fat daily and 100g sugar from 1kg fresh fruits. Massage oil is palm oil.
Please ask me if you need assistance.
