The plan is a high-fat and low-carb (HFLC) diet. I would actually describe it as extremely low-carb-you're allowed to eat just 20 grams in a day. Some people on keto follow a net-carb plan (you can subtract the grams of fiber from a food's total carbs) and you're allowed to eat more carbs in a day. For my 30-day diet and for the sake of simplicity, I stuck with total carbs.
