I'm sorry to hear about your foot problem. I hope you get it resolved soon.
I don't know if it can arise from a lack of fruits and carbs in your diet, but I do know that some vitamins and phytonutrients are more prevalent in fruit than vegetables and unless you are eating a LARGE RANGE of vegetables, you may not be getting these important nutrients. Fruits are always right up there on the lists of foods with the most bang-for-your-buck (especially berries).
Personally, I do not thrive on the Bernstein diet (sorry Lanie and fergusc). My sugar runs higher and I have less energy when I try to eat strictly according the low carb proportions. I have tested myself extensively (you know what a data freak I am) and have shown over and over that my sugar stays stable, in a normal bg range (80-95), and I have a greater amount of energy when I include more carbs from fruits. beans, and some whole grains. I even had to up my carbs, to keep my bg from rising last week when I was visiting my daughter and we were on the go all day.
I am routinely eating about 80 -100 net carbs (I subtract the fiber Atkins style) a day, with no adverse effects on my readings. I eat unprocessed, in-season, local, and organic (where practical) foods as much as possible. I am still linking- and balancing my proteins and carbs. I arrived at this range by incrementally (10 carb increments) increasing my carbs until I was seeing numbers over 95 consistently. Then I cut back by 10 carbs a day until I hit the correct range. I have to re-adjust every time I up my exercise, or hit a new fitness level.
My guess is that with some trial and error, you'll be able to find a good balance of heart healthy foods that will not impact your bg and that may improve your overall health and well-being.
I'll be praying for you.
I just want to live happily ever after-every now and then. Jimmy Buffett
