You think it’s crazy. But just follow this logic.
High cocoa chocolate does increase blood flow to muscles. –> This results in an increase in oxygenation and nutrients to the muscular tissue.
–> This results in an increase in the number of energy producing mitochondria in the muscles.
–> This also produces more energy producing folds WITHIN EACH of those increasing numbers of mitochondria.
Thus, ergo, therefore, and soooo, that’s why people who consume high cocoa chocolate on a long term basis report reduced fatigue, increased energy.
Eat the chocolate. It’s Spock level logical.
