Outcome Measures

Primary Outcomes (1)

  • Diet-induced thermogenesis

    Before treatment consumption, participants will be rested in a supine position for 30 min to reach a steady resting state in an isolated, dimly lit room under controlled temperature and humidity conditions. Resting energy expenditure (REE) will be determined by indirect calorimetry (ParvoMedics TrueOne2400 automated metabolic gas analysis system, ParvoMedics, Sandy, UT, USA) under a ventilated hood for 30 min. Post-treatment consumption, respiratory gases will be measured in 30 min intervals for 3 hours under the ventilated hood using the indirect calorimeter, with a 30 min rest break between measurements. Diet-induced thermogenesis (kcal/h) will be calculated as the increase in energy expenditure above baseline REE over the duration of the measurements.

    Collected at baseline (before treatment consumption) and 30-min intervals for 3 hours post-treatment consumption.

Secondary Outcomes (3)

  • Substrate oxidation

    Collected at baseline (before treatment consumption) and 30-min intervals for 3 hours post-treatment consumption.

  • Glycemic response

    Collected at baseline (before treatment consumption) and 5-min intervals for 3 hours post-treatment consumption.

  • Subjective appetite

    Collected at baseline (before treatment consumption) and 30 min intervals for 3 hours post-treatment consumption.

Eligibility Criteria

Age18 Years - 45 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Participants (18 - 45 years) who are considered healthy, are non-smokers, and have a body mass index (BMI) between 20 and 24.9 kg/m2 \[World Health Organization classification of normal weight BMI\].

You may not qualify if:

  • Participants who have a fasting plasma glucose \> 5.5 mmol/L indicative of impaired fasting glucose, previously diagnosed diabetes, known or uncertain pregnancy status at the screening visit, gastrointestinal disease, liver or kidney disease, have undergone a major medical or surgical event within the past 6 months, were or are on a diet, skip breakfast, smoke or have taken medication which would be a potential confounder with effects on metabolic and intake regulation.
  • Those unable to complete the testing protocols or are intolerant or allergic to test-day ingredients.
