The biggest potential complication to a diabetic going minimalist is the presence of neuropathy. If there is neuropathy (loss of sensation), steps can be taken to slow or reverse it before barefoot activity is undertaken. It is NOT recommended if you are completely neuropathic.
If you are a diabetic and looking for alternative, natural, holistic, or complementary means of fighting diabetes, please visit this link on the national center for complementary and alternative medicine's website for helpful suggesions: http://nccam.nih.gov/health/diabetes/CAM-and-diabetes.htm
My favorite two alternative treatments that I suggest to diabetics are as follows:
1. For early neuropathy, Alpha lipoic acid (ALA) 600mg daily, works wonderfully. Thought to aid in nerve function, studies in Europe has shown its effectiveness for improving neuropathy symptoms and pain, especially in diabetic neuropathy.
2. Green tea has been shown to have beneficial effects on blood glucose level. There are conflicting studies out there about its true effects, but green tea is not a bad item in your diet no matter what, especially if it helps change your lifestyle. Replacing that soda or other sugary drink with tea (with a little sugar, honey or artificial sweetener) is better for a diabetic whether or not it has potential blood glucose stabilizing effects!
