causal

When people with excess body fat eat very few carbs and more fats, their bodies burn more fat for fuel during intense exercise, as shown by lower respiratory exchange ratio measurements.

Scientific Claim

Very low-carbohydrate high-fat diets significantly reduce respiratory exchange ratio (RER) during maximal exercise in overfat adults, indicating increased fat oxidation.

Original Statement

RERpeak significantly decreased in the VLCHF and VLCHF+HIIT groups, as was shown in our previous studies. This indicates an increased rate of fat oxidation.

Assessment Explanation

The study directly measured RERpeak and found significant decreases in VLCHF groups, which is appropriately described as indicating increased fat oxidation. The causal language is appropriate for this specific physiological measurement.
