Are you using their defaults? Because they are no where near being Keto. For a keto/lchf plan your fats at 70+g. carbs, 20 g, protein ±100 grams or something close to that.
I’d ditch the shake. Make your own with almond and or coconut milk, yogurt, berries, 100% Cocao Powder, dash of stevia if needed. Or a green one with leaf veggie instead of the berries. What ever floats your boat.
As others mentioned you have to change over to a fat burner. You do that by going as low carb as you can stand. That can take months for some, a few days for others, and I have heard of it taking up to a year for a few people all depends on how broken your system is. Once you become a fat burner, think about doing at least intermitten fasting.
All the best sorting this out.
