Well, I could live on them, but I wouldn't like them.
I would be interested to know if they are trying to change eating habits generally, or specifically considering trying to go low carb to drive BG levels into the normal range specifically by that method.
If not, is it for any reason they have encountered.
Certainly, at courses and general conferences, getting the Mars bars off many was considered a life changing event.
Even before I reversed my diabetes, I didn't low carb, as I certainly found all carbs weren't equal, and it was way too difficult to fit into my lifestyle.
As to calories, while 1600 to 1800 may be high for some, it's about half of what I, and many, were eating.
