Is there are difference between keto and low carb. By nature the keto diet is a low carb diet. Rather me explaining it, watch the video by Dr. Sten Ekberg. As a doctor he better qualfied to tell you the differences.
I started following these guidelines long before I saw this video and my weight has just fallen off without heavy workouts. I now fit into clothes I had not be able to wear since before I had kids 40 years ago.
