For one data point, I do it for about $70 a week, $100 if I'm splurging (a couple nice cuts of steak or something.) During lean times, I have gotten it as low as 30 bucks, but I wouldn't recommend that. One surprising expense on keto is Lite salt. Your body doesn't retain fluid in ketosis, you'll lose 5-10 pounds the first week in just that, and so you need to increase your sodium and potassium intake significantly compared to a non-ketogenic diet. Lite salt is absolutely perfect for that, being a 50/50 mix of potassium and sodium. It adds about 10 bucks to my grocery bill a month but it's definitely worth it especially when starting out, to avoid the dreaded keto flu.
