Marc Bates, a metabolic health coach, announced the release of a new YouTube video presenting scientific evidence that humans evolved as fat-burning organisms rather than sugar-dependent creatures. The video challenges conventional dietary wisdom by positioning ketosis as humanity's natural metabolic state.

The announcement comes as growing numbers of health professionals question modern carbohydrate-heavy dietary recommendations. Bates argues that anthropological evidence reveals a fundamental misunderstanding of human evolutionary nutrition.

"Carbohydrates were the exception, not the rule," Bates stated. "Most of the year, fruits and sweet plants weren't even available, except in tiny amounts."

The video presents stable isotope analysis of ancient human bones as key evidence. According to Bates, anthropologists analyzing early human remains find isotope signatures proving high-protein, high-fat diets dominated human nutrition for millennia.

"We weren't grazers or fruitarians, we were fat-fueled carnivores," Bates explained.

The metabolic health coach describes modern high-carbohydrate consumption as creating chronic hyperinsulinemia. This constant high-insulin state suppresses fat oxidation, overwhelms mitochondria, and increases oxidative stress and inflammation.

"By eating a constant supply of carbohydrates, we enter into a constant high-insulin state," Bates noted. "Fat oxidation is suppressed, mitochondria get overwhelmed, oxidative stress and inflammation build up, and disease risk goes up. We just get used to basically being ill."

The video aims to educate viewers about returning to metabolically appropriate nutrition based on human evolutionary biology rather than modern dietary guidelines.
