NCT02343380

Brief Summary

The investigators aim at analyzing whether eating a standard meal in the evening (at 8:00 pm) determines in the same individuals a lower diet-induced thermogenesis (DIT) and a different hormonal response than the consumption of the same meal in the morning (at 8:00 am). The primary outcome is: the intra-individual variation in DIT after the evening and morning meal consumption. The secondary outcomes are the intra-individual variations in glucose, triglyceride, insulin, free fatty acids, leptin, glucagon-like peptide-1, acylated ghrelin, adrenalin, noradrenalin, after the evening and morning meal consumption.

Outcome Measures

Primary Outcomes (1)

  • Intra-individual Variation in Morning Diet-induced Thermogenesis (DIT) Evaluated by Calorimetric Exam After the Consumption of a Meal at 8:00 am Compared With Evening DIT Evaluated by Calorimetric Exam After the Consumption of the Same Meal at 8:00 pm

    Indirect calorimetry by Deltatrac II (DATEX, Division of Instruments Corp. Helsinki, Finland) is used to measure the rate of energy expenditure before- and after- the meal.Diet-induced thermogenesis is considered as the difference between average after-meal and basal energy expenditure.

    Before and 180-min from the beginning of the meal

Secondary Outcomes (5)

  • Variation in Morning Glucose and Insulin Area-Under the Curve (AUC)s After the Consumption of a Meal at 8:00 am Compared With Evening Glucose and Insulin AUCs After the Consumption of the Same Meal at 8:00 pm

    From the beginning of the meal for 180-min

  • Variation in Morning Triglyceride and Free Fatty Acid (FFA) Area-Under the Curve (AUC)s After the Consumption of a Meal at 8:00 am Compared With Evening Glucose and Insulin AUCs After the Consumption of the Same Meal at 8:00 pm

    From the beginning of the meal for 180-min

  • Intra-individual Variations in the Values of Adrenalin and Noradrenalin, After the Morning and Evening Meal Consumption

    Every 30-min from the beginning of the meal for 180-min

  • Intra-individual Variations in the Values of Acylated Ghrelin After the Morning and Evening Meal Consumption

    Every 30-min from the beginning of the meal for 180-min

  • Intra-individual Variations in the Values of Glucagon-like Peptide-1 After the Morning and Evening Meal Consumption

    Every 30-min from the beginning of the meal for 180-min

Interventions

The calorimetric and metabolic responses to identical meals (a high-protein, low-carbohydrates meal) consumed in the morning (8:00 am) and in the evening (8:00 pm) are measured in healthy volunteers, after standardizing diet, physical activity level, duration of fast and resting
