Foraging requires focus, rapid assessment, impulsivity, exploratory behavior and risk taking. It is enhanced by blocking whatever gets in the way, like recent memories and attention to time. Fructose, a kind of sugar, helps damp down these centers, allowing more focus on food gathering.
In fact, the researchers found the entire foraging response was set in motion by the metabolism of fructose whether it was eaten or produced in the body. Metabolizing fructose and its byproduct, intracellular uric acid, was critical to the survival of both humans and animals.
The researchers noted that fructose reduces blood flow to the brain’s cerebral cortex involved in self-control, as well as the hippocampus and thalamus. Meanwhile, blood flow increased around the visual cortex associated with food reward. All of this stimulated the foraging response.

Nutrients | Private Interests and the Start of Fluoride-Supplemented High-Carbohydrate Nutritional Guidelines
Internal documents show that private interests motivated the events which led these expert panels to engage in pivotal scientific reversals. These private interests biased scientific processes and these reversals occurred largely in an absence of supporting evidence. It is concluded that private interests played a significant role in the start of public health endorsements of fluoride-supplemented high-carbohydrate nutritional guidelines.

Fasting induces a highly resilient deep quiescent state in muscle stem cells via ketone body signaling: Cell Metabolism
fasting slows muscle repair both immediately after the conclusion of fasting as well as after multiple days of refeeding. We show that ketosis, either endogenously produced during fasting or a ketogenic diet or exogenously administered, promotes a deep quiescent state in muscle stem cells (MuSCs).

Toward a useful physical education
We have widespread ill health. And in the US 42% of us have become obese. PE didn’t help most people.
Entertainment, porn, and sports show us buff physiques to consume. We prominently reward athletes. And advertising sells us convenient food.
We train people to external direction. Our received ideals of fitness come from military preparedness. And we measure and praise performance. Why?
Ill health increases. And the fitness industry grows. This is not working. This fitness does not help most people.
We are going to spend too much time sitting. We are going to look at screens a lot. How do we teach ways of moving as lifelong harm reduction?
Hope
We must teach hope because without it everything else we can teach won’t get used.
