Dudley, I'm not sure whether you have excluded wheat/gluten foods yet? That made a big difference to me as I told you. I didn't know how bad it was at the time of eating them, but removing sugar and yeast were not enough. I had to remove all gluten grains/breads from my diet too.

It was well worth it. Gluten grains are anything with wheat, oats, barely, rye etc.

I even found (at that time) that the warmth in my body increased as well as many symptoms being relieved and finding much improvement in my health and more energy and strength.

I had non wheat/gluten cereals made from corn, or rice etc(making sure to check ingredients in case they contained any byproducts of gluten grain), rice, etc. Of course, I cannot eat any grains these days because my immune system is worse, so all high carbohydates have had to be dramatically reduced. But back then I was ok, so long as it was sugar, yeast and wheat/gluten free.

Once you are on the diet fully and for long enough, then you can start to notice some changes, but it can take weeks of adherence.
