Summary

In this study, the investigators are interested in investigating how the emulsification state and amount of fat in a meal can modify the kinetics of postprandial lipemia and inflammatory outcomes (including endotoxemia) in obese vs lean subjects.

10 lean and 10 obese volunteers will come 3 times (\>3 weeks apart) at the investigation center to receive a standard breakfast containing milk fat (10 g non emulsified, or 40 g non emulsified, or 40 g finely emulsified). 13C triglyceride stable isotopes will allow to follow the metabolic fate of fatty acids and calculate lipid oxidation by breath test. Blood sampling throughout digestion will allow to measure metabolic, lipid and inflammation parameters. Stool will be analysed to determine lipid losses in faeces and to phenotype microbiota.

Interventions

OTHER

All subjects receive three sequences of a standard breakfast

All subjects receive three sequences of a standard breakfast containing : * 10 g non emulsified * or 40 g non emulsified * or 40 g finely emulsified of milk fat with stable isotope (13C triglyceride). The administration order is determined by randomized allocation. The wash-out period is three weeks. There are not diet or exercise interventions. Only, one week before and three days after, the subjects consume neither naturally enriched in 13C foods or pre/probiotics. In addition, three days before and three days after each test, the subjects receive dietary instructions
