Sounds like you caught this pretty early which is a good thing. Many of use before diagnosis were pretty healthy and not overweight. I used to spend 2-3 hours a day in the gym for 5 years before I was dx'd. I was also a vegetarian. So, boy was I surprised. But what I have found is it is not just sugar but all carbs that cause me problems. So I have to watch my intake of things like brown rice, whole grain cereals and whole grain bread. I found the only bread that will allow me to stay under 100 is Eziekel sprouted bread. I can usually manage about 15 carbs at one sitting. Much more than that and I spike way too high, for way too long. Do they make the coconut water without the added sugar? For the past few months I've added coconut oil to my diet at every meal and find it works great at regulating my bgs.
