My father aged 52 years is suffering from Diabetes for 3-4 years. Initial Diagnosis from Insulin Levels and C peptide test is of Type 2 DM only. His BMI is 23 and has remained around it for the whole of his life. He has a Grade 1 Fatty liver too, with the last HbA1c of 6.5%. How can we reverse his Diabetes completely using diet and exercise while maintaining a healthy weight? What are the parameters, which defined as cure of diabetes? Should we go for some antibody tests to rule out any autoimmune form of diabetes of LADA/Type 1.5 Diabetes?
