I have a close relative with cancer. I have celiac disease and have been studying the metabolic pathway diligently for almost two years. I’m not an expert, but I know what I know.
So far, one medical professional has claimed that sugar can’t cause cancer, because the body produces sugar even if we don’t eat it. And two people said they got cancer, or a recurrence of cancer after abstaining from refined sugar in favor of fruit ......abstaining from sucrose in favor of fructose.
Refined sugar is half fructose.
Starving people can feed on their own fat for a couple weeks to a couple months before death. If humans required ingested sugar, people would starve to death within a few hours of their last meals. This does not happen.
Blood glucose is required by a few brain cells because they are too thin to contain mitochondria. The majority of brain cells do not need sugar. Humans do not need to eat sugar to live. And yes, our liver have mitochondria which manufacture glucose out of protein and fat. It’s called gluconeogenesis. The purpose is to feed the few brain cells which need it.
Cells use mitochondria to metabolize sugar into energy.

The body has three main methods of making energy from sugar:
* ATP/CP System
* Anaerobic Lactic Acid System
* Aerobic system.
So far people have ascribed body acid from sugar through the lactic acid system. All three energy systems produce acids and destroy tissue.
In all three systems mitochondria use sugar, produce acid, and destroy tissue. The end product of all three systems is adenosine triphosphate (ATP), known as the cell’s energy currency. Cells are capable of consuming fat directly or via "ketone bodies" .......a fancy term for lightweight hydrocarbons. The liver can convert fat into ketone bodies. Any unused ketone bodies get expelled in the urine, and by the lungs.
As I mentioned above, the liver can convert fat and protein into glucose. The glucose could be consumed by all cells, except for a couple of facts. 1) The brain uses chemicals to claim first dibs on this glucose, and 2) the liver uses chemicals to limit glucose production to the amount needed by the brain.
An important factor has been neglected here. Sugar molecules are sugar because they have lots of hydroxyl (OH) ions. When cell mitochondria process sugar, as a byproduct, they create hydrogen peroxide (H2O2). Cellular vehicles feed needed chemicals to mitochondria. When these vehicles break, mitochondria produce more and more H2O2. H2O2 is a bleach. Compared to water (H2O), hydrogen has an extra oxygen radical (O) which it tries to get rid of. Radical oxygen creates localized acidic conditions throughout the body. Radical oxygen attempts to attach to cells everywhere, essentially burning them.
In contrast, when the liver makes glucose from protein and fat, it reverses the normal cellular metabolic process. Unlike in sugar-using metabolism, sugar-creating metabolism creates hydrogen (H) ions as a byproduct. The hydrogen ions flow through the body absorbing free oxygen radicals. It absorbs the radicals from hydrogen peroxide (H2O2) and from the tissue burned by the hydrogen peroxide.
So when a detractor argues against the Warburg effect by claiming the liver manufactures glucose anyway, it’s just bogus. Sugary glucose, whether digested or manufactured represents disease, but manufactured glucose comes with its own cure .......its own neutralizing agent.
Now add that cells burn fat, average about six times as efficiently as sugar. The ATP system is three times as efficient, and the other two systems are between six and twenty times as efficient.
Sugar is good for cancer, and bad for humans. Cancer requires sugar. Humans do not.
