Really Good Book & Inspired Me to Take Action
Format: Hardcover
After I finished reading the book, I asked my doctor for a Continuous Glucose Monitor. For two weeks, I reduced my carb & sugar intake & was able to keep my glucose in the "steady" range. Then, I ate an oatmeal cookie without pre-eating any fiber or protein. BIG SPIKE! One cookie sent my glucose soaring. I can't even imagine what happens to my body when I eat 1/2 pound of candy. This book was written in a very understandable way & it inspired me to start tracking my glucose levels. I recommend reading this book. And there is definitely something about seeing the effect on your body when you eat sugar by using a CGM. It's an almost immediate visual telling you that you're inflicting damage on yourself. When you don't see it, you can pretend it's not really happening. When I saw that spike, I imagined my poor body trying to release all that insulin to remove sugar from my blood.

Great Book to Understand How Diet Impacts Blook Sugar and Health
Format: Hardcover
Life changing book that helped me understand how sugar and processed foods impacted my health. I verified the tips in this book with my own blood glucose monitor. The tips that she shared helped me reduce my glucose spikes and helped me enjoy a little snack from time to time.

FIVE STARS!
Quality is as good if not better than the Brand name Water picks. This flosser is super powerful and gets the spots a toothbrush can’t! I would recommend it to anyone.
