In September 2014, I was diagnosed with type 2 diabetes. My A1C was 8.9, and I weighed 241. I went low carb, high fat, and lost 50 lbs and I still struggled to keep my blood sugar under 100. I found biking, and now I am consistently under 100. My last A1c test was 4.7. my blood sugar is always lower the day after I ride. I'd much rather spend time on my bike than taking Metformin or any other diabetic drugs.
