Eating better will help anyone that eats poorly, and we all do. According to this $54.39 book you will power your blood pressure by 39%, increase your glucose metabolism by 20 fold, lower your cholesterol by 30%, and simply reduce your risk of dying by 42%. If you have diabetes then your doctor has likely already informed you that eating better can help to reduce the effects of diabetes. You should eat better no matter who you are, but you don’t need this book to tell you some simple trick. according to Wikipedia “Type 2 diabetes primarily occurs as a result of obesity and not enough exercise”. You can loose some weight without spending money on a quick fix… start by simply going for a walk, and see where the road takes you.

TL;DR – Eating poorly makes you gain weight… obesity leads to Type 2 diabetes. Eat better. Feel better.
