The Claim
In elite race walkers, adherence to a ketogenic low-carbohydrate, high-fat diet for 3 weeks is associated with increased blood ketone concentrations (specifically β-hydroxybutyrate) during exercise, reaching approximately 1 mmol/L, indicating the presence of metabolic ketosis even during high-intensity endurance activity.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Elite race walkers who follow a keto diet for 3 weeks start burning fat for fuel during intense exercise, and their bodies show signs of ketosis — like having 1 mmol/L of ketones in the blood — even when working hard.
See the scientific wording
In elite race walkers, adaptation to a ketogenic low-carbohydrate, high-fat diet for 3 weeks is associated with elevated blood ketone concentrations (β-hydroxybutyrate) during exercise, reaching levels of approximately 1 mmol/L, confirming metabolic ketosis even during high-intensity endurance activity.
What the research says
1 studyThe study looked at race walkers eating a very low-carb, high-fat diet for 3 weeks, and found their bodies burned more fat during exercise, which usually means they were in ketosis.
