Metabolic health coach Marc Bates has released a YouTube video calling for radical reform of nutrition science methodologies, citing fundamental flaws that create public confusion about dietary recommendations.

Bates argues that current nutrition research relies excessively on epidemiological studies originally designed for tracking contagious diseases, not nutritional causation. This methodological mismatch produces unreliable data through food frequency questionnaires that ask participants to recall eating habits over extended periods.

"Studies use epidemiology as their base statistical format, which was not designed to track nutrition and is only used to track correlations," Bates explained. "This works fine for contagious diseases because you're looking for where the source of the disease, where in nutrition we're looking for the cause of the nutritional problem."

The coach highlighted how this approach creates contradictory headlines about foods like red meat. He cited one study where flawed methodology could have produced the absurd conclusion that "fast food is healthier than fish and vegetables."

Bates proposes three fundamental shifts to reform nutrition science: biomarker-driven cohorts measuring biological responses, short iterative randomized controlled trials focusing on metabolic outcomes, and evolutionary reality checks triangulating findings against human evolutionary history and clinical outcomes.

The announcement comes as public confusion about dietary recommendations continues to undermine confidence in nutrition science, particularly affecting understanding of ketogenic and carnivore dietary approaches.
