Hi, about 6 weeks ago I started on the Low Carb diet, very quickly I started to notice how well I was feeling with much lower Blood sugar scores increased insulin sensitivity but managed to put on 5kg which left me and the dietician mystified. Because of the unexpected weight Gain, a friend suggested to me that I may have an under-active Thyroid. After an initial GP consultation (with a new GP) I had a thyroid and cholesterol test, both were normal. The GP then shocked me by saying (1) I was on the on the wrong diet, (2) it was a waste of time recording Blood sugars insulin dosage, and carbs in a diabetes diary, (3) diabetes did not cause the metabolism to be impaired, and (4) there were no further tests of the endocrine system that could be done. I must say I was a bit shell shocked at these statements as they seem so at odds with ther other advice I have had from Endocrinologists, Dieticians and other GPs. I plan to see my regular GP to check this out furthering a couple of weeks . Are these GP statements crazy or is it me?
