Donal Collins, MBChB


I have been a GP for 28 years, and during this time treated my diabetic patients with the usual advice and medications which confirmed what I had been taught: this is a progressive disease that can only be slowed down. Then a few things happened. I noted some patients' dramatic reversal of their disease. Then I developed type 2 diabetes much to my horror. I did the traditional approach, cal in/cal out, with no effect on my HbA1C. Then I learned from my patients and adopted LCHF. I have advised 100s with great success. My career is now joyful. I use Diet Doctor for short intervention advice and big impact.
