Early this year I came across a Ted Talk by a microbiologist whose main point in the talk is that cancer cells love sugar. She can watch such cells multiply under a microscope when fed sugar. That cancer cells like sugar has evidently been known for some time but that revelation was news to me. As a consequence, I've given up most sweets and the fat has been melting off. I'm a bit below my high school weight but mostly I now have a flat stomach.
