descriptive
When people with excess body fat eat very few carbs and more fats, their blood ketone levels rise quickly within two weeks, showing their body has switched to burning fat for fuel.
Scientific Claim
Very low-carbohydrate high-fat diets significantly increase blood ketone levels (β-hydroxybutyrate) in overfat adults within 2 weeks of intervention, indicating nutritional ketosis.
Original Statement
“The β-hydroxybutyrate concentration (βHB) increased substantially in the VLCHF and VLCHF+HIIT groups. The highest βHB concentrations were achieved after 2 weeks of VLCHF diet intervention.”
