  Purpose

In this study, the investigators are interested in assessing the effects of the isocaloric increase of eating frequency on appetite and metabolism. How the consumption of an isocaloric breakfast in four intakes vs. one can modify satiety and appetite control in lean and obese subjects through :

  • the physiological consequences : difference in postprandial kinetics of glucose, non esterified fatty acid, triglyceride, the secretion of satiety gut hormone (insulin, ghrelin, leptin and cholescystokinine (CCK), peptide YY (PYY), glucagon-like peptide-1 (GLP-1), nutrients oxidative fate and plasmatic oxidative stress (Malondialdehyde (MDA), glutathion, lipid hydroperoxides)
  • eating behavior during an ad libitum buffet test meal

Condition Intervention
Volunteers Other: Increasing eating frequency

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: Behavioural and Metabolic Consequences of Increasing Eating Frequency

Further study details as provided by Hospices Civils de Lyon:

Primary Outcome Measures:
  • Ghrelin plasmatic concentration [ Time Frame: 240 minutes after breakfast beginning (just before the lunch) ]

Secondary Outcome Measures:
  • Satiety through food intakes (quantitative) at the ad libitum buffet test meal [ Time Frame: Since the beginning of the buffet test meal (240 minutes after breakfast beginning) to the end of the meal (at the latest 270 minutes after breakfast beginning). ]
  • Satiety through visual analogue scale [ Time Frame: 240 minutes after breakfast beginning (just before the lunch) ]
  • Plasma metabolite concentrations (glycaemia, non esterified fatty acid, [ Time Frame: kinetics during 430 minutes ]
  • Endocrine concentrations (insulin, ghrelin, GLP-1, PYY, leptin, C-peptide) [ Time Frame: kinetics during 430 minutes ]
  • Plasma markers of oxidative stress (MDA, gluthation, lipid hydroxide) [ Time Frame: kinetics during 430 minutes ]
  • Lipid oxidation [ Time Frame: kinetics during 430 minutes ]
  • Eating behaviour at the buffet test meal by video recording (food choice, nutritional composition of the meal , kinetics of nutrient intake, meal structure, lunch duration) [ Time Frame: during the buffet test meal (max : 30 minutes) ]

Arms Assigned Interventions
non-obese volunteers
Volunteers with a BMI (Body Mass Index) between 20 and 25 kg/m2.
Other: Increasing eating frequency

The subjects receive the same breakfast with two sequences :

  • breakfast in one intake at 8:00
  • breakfast in four isocaloric intakes (8:00, 9:00, 10:00, 11:00) The sequence made twice : one for metabolic study and one for the study of eating behavior

The lunch during metabolic study is a standard meal The lunch during behavioural study is an ad libitum buffet test meal.

The administration order is determined by randomized allocation. The wash-out period is one to three weeks.

There are not diet or exercise interventions.
