Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Fasting lipids, postprandial lipaemia, insulin resistance - The determination of total cholesterol, triacylglycerol, high density lipoproteins will be performed on an automated Roche Cobas Mira Plus spectrophotometric analyser (Cobas Mira Plus (ABX Diagnostics, France), by enzymatic calorimetric method using commercially available kits (ABX Pentra, Horiba ABX, France). Quantitative insulin analysis will be performed by using a commercially available enzyme-linked immunosorbent assay (ELISA) kit (Mercodia AB, Uppsala Sweden) and plasma glucose will be analysed using a commercial assay kit (Life Sciences, Cambridge, UK) and an automated Cobas Mira biochemical analyser. 2. Energy intake and body mass - For measurement of rate of energy expenditure (EE) a ventilated hood system (Oxycon Pro, Jaeger GmbH, Hoechberg, Germany) will be used. On day 6, the participants will be requested to come to the metabolic room at the Human Nutrition Section (School of Medicine, College of Medical Veterinary and Life Sciences, Glasgow, UK) at ~ 08:30am in a fasted state. Participant height, body weight and fat mass will be measured and fasting blood samples will be collected. Then approximately 10-15 minutes will be given to the participant to rest and acclimatize with the environment. Subsequently metabolic rate will be measured for a duration of 20 minutes. The participants will be asked to consume ad libitum buffet breakfast and lunch. Following breakfast and lunch blood samples will be collected at 30, 60, 90 and 120 minutes. Immediately at all time points at which blood samples will be collected following breakfast and lunch appetite will be measured using visual analogue scales. In addition, the rate of energy expenditure (EE) for the duration of 20 minutes will be measured at all time points after breakfast and lunch. The amount of food offered and leftover during ad libitum buffet breakfast and ad libitum buffet lunch will be recorded by the researcher. Body height will be | — |

| 1. Appetite measures - appetite sensations will be measured with validated appetite questionnaires (Flint, Raben et al. 2000). Venous blood samples will be collected in 9 ml vacutainers containing EDTA and then appropriately treated with chemicals prior to preparation of plasma. 2. Metabolic rate | — |
