Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Thermic effect of food | 6 h | Measurement of thermic effect of food over 6 hours after a meal rich in test oil and control oil. The thermic effect of food is the difference between post-prandial energy expenditure and basal energy expenditure. We will assess the difference in thermic effect of food over a 6-hour period between the test oil and the control oil. |
| Respiratory quotient/fat oxidation | 6 h | Measurement of substrate oxidation by indirect calorimetry over 6 hours after consumption of the test oil and control oil. We will specifically calculate carbohydrate and fat oxidation rates over the 6-hour period post-prandially and compare rates of oxidation of these two substrates between the test oil and the control oil. |
| Food intake | single meal | Measurement of food intake at a single meal served 1 hour after a pre-load containing 8-10 g of the test oil and the control oil |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Leptin | 6 hours | Measurement of leptin over 6 hours after consumption of the test oil and control oil |
| Ghrelin | 6 hours | Measurement of ghrelin over 6 hours after consumption of the test oil and control oil |
| Glucose | 6 h | Measurement of glucose over 6 hours after consumption of the test oil and control oil |
| Glucagon like peptide 1 | 6 hours | Measurement of glucagon like peptide 1 over 6 hours after consumption of the test oil and control oil |
| Peptide YY | 6 hours | Measurement of peptide YY over 6 hours after consumption of the test oil and control oil |
| Feelings of appetite and satiety | 6 h | Measurement of feelings of appetite and satiety by visual analog scales over 6 hours after consumption of the test oil and control oil |
| Insulin | 6 hours | Measurement of insulin over 6 hours after consumption of the test oil and control oil |
