Hi Skinny43, There are no hard and fast rules for Low Carb or even for Keto. In the case of Low Carb, beware of all fruit , all grains and all starches. But we are all different, some can eat an apple or a potato or a carrot etc. but others can't. It isn't just the quantity of Carbs, but individual food types that vary in effect from person to person. Low Carb could be anything from around 120gms per day, right down to about 20gms per day. You need to use your BG Meter in order to determine what and how much you can tolerate , and how low you wish to go. Keto can be as high as 50gms carbs all the way down to 0 gms. Again, use of Keto testing strips will tell you how low you need to go to be in Ketosis.
