Yes, my total cholesterol was at 199 about three decades ago, the highest it had ever been, down to 123 in six weeks, by changing to a diet of white rice and fruit.
I continued the diet with portion control for four months and went from 170 to 133 pounds.
Thereafter I continued the diet without the strict portion control and kept my weight at 143 for another four years.
Since then I have kept a similar diet based on similar amounts of complex carbohydrates, protein and no excess fat.
My total cholesterol, blood pressure and resting heart rate have continued to be low.
