Dietary Supplementation on Fat Oxidation

Recruiting now · Not applicable · Has a placebo group

Conditions studied: Overweight, Obesity

In brief

The purpose of this pilot study is to evaluate the effects of 4 weeks of daily consumption of encapsulated N-trans-caffeoyl tyramine (NCT) and N-trans-feruloyl tyramine (NFT) at a dose of 120 mg/d on measures of fat oxidation in women with overweight or obesity. The hypothesis is that fat oxidation at rest (measured via indirect calorimetry) and over a 24 h period (measured via d31-palmitic acid stable isotope tracer) will be higher in the group receiving the active study product compared to the control product at the end of the 4-week consumption period.
