I read Bernstein a few years ago, and tried his approach. I’m pretty sure it brought my A1c down from about 6.8 to 6.2. I don’t think it did a lot for my overall health. If you’re a Bernstein follower - good luck.
About two years ago I learned about Team Type 1. If you haven’t read their story - you should. I’d like to listen to Phil Southerland and Dr. Bernstein debate carb intake.
I’m 50 years old and cycle to stay healthy and keep my insulin needs low. I eat a ton of carbs when I exercise. I eat a ton of carbs after a good ride. I eat a ton of carbs before a hard ride. My A1c varies between 6.2 and 6.8. I can ride a bicycle 100 miles. I’m average.
This is one of my favorite bike rides. My house to the visitor center in the Colorado National Monument. About a 1200’ climb, only 8 miles. Make sure your BG is over 100 to start. Eat about 40 grams of carbs. (Clif Bar, or Three Musketeers, or PopTart…yummmmmmy!) Cut your basal in half. Ride your heart out for an hour. Eat another 30 when you get home. Bolus for 1/2 of what you ate. Keep this up and your TDD drops considerably!
