I'm not sure why you're here? If you have TYPE 1 then changing your diet would not make any difference at all in "improving" your symptoms. It's an autoimmune disease, our bodies simply don't make any insulin.. changing what we eat, does not change that fact.
Talk to your doctors if you have concerns.. and stop using google to diagnose yourself
Also AFIAK, calluses are not a symptom of diabetes.. I've had callused feet since I was 13 or 14.. I didn't develop T1 until 6 years later. My mom has had them all her life...
