It’s refreshing to see people beginning to think clearly and rationally and move away from gimmicky diets that have little basis in fact, reality, or objectivity, and to ones that are firmly seated in all aspects of human physiology and science.
After all, this is why most of us choose to eat a certain way, that is to be as healthy as we can be, both physically and mentally . . . not to, say, replicate how our caveman ancestors supposedly ate and lived.
It’s due to this line of reasoning that carbohydrates, and especially sugar and fructose, have fallen by the wayside of late, driven by an irrational fear, bordering on obsessiveness, that’s evolved to where sugar is now conceived of as a toxic poison and blamed for causing diabetes, cancer, obesity, gout, etc. (Thank you Dr. Lustig.)
It’s important to point out that sugar is used by virtually every cell in the body to generate energy, or ATP. The brain is especially reliant on glucose for optimal functioning: The brain represents only 2 percent of the body’s total weight yet accounts for 15 percent of the body’s total energy expenditure. 1 Indeed, the brain is a voracious sugar guzzler, and sugar, not ketone bodies, is its preferred fuel source, despite popular discourse to the contrary. Insulin and sugar make us smarter 2 so it stands to reason that ketosis has the opposite effect.
