First off, congratulations for a brilliant result.
I'm glad you have found a diet that works for you.
As to the cholesterol, again, that's personal. Most lchf that stay on the diet report good results, others seem to be not so good and move onto a different path. The only way to know is to stick with it. Get the bs under control, then target the cholesterol. You'll know it the diet is working if the blood tests tell you!
My GP is good about testing, they do bloods every 3 months or so, when I ask them. So I can change my diet from targeting weight loss and getting the bs right, to targeting cholesterol, and I will know if it's right or not.
Get the nurse to check yours regularly as well at the Ha1bc.
