Week one. Start consume dietary ketones (Best is Ketones in a can (most expensive, all ketones, tastes bad), next is MCT (Medium Chain Triglycerides, usually made from coconut oil) (less expensive, 50% converted to ketones, little taste), next is liquid Coconut oil, least expensive, 20% converted to ketones, little taste). These are converted to Ketones and will restart your fat metabolism. This will prevent weakness due to lack of carbs (Keto flu) or even Diabetic Ketoacidosis if your fat metabolism can't keep your body supplied with energy.

Week two. Stop consumption of wheat or potatoes, continue with dietary ketones.
Week three. Stop consumption of wheat AND potatoes, continue with dietary ketones.
Week four. Above plus reduce other high carb vegetables. Goal is 15g carbs per 6 hour meal period, 25 g per day.

Continue to follow a ketogenic diet, I suggest the Wheat Belly Total Health book. It include a list of supplements and maintaining certain level of thyroid hormones.
