NCT03157778

Brief Summary

Measured plasmatic concentration of pregnenolone and endocannabinoid in fasting conditions and over a meal in obese and normal-weight men subjects, to research a dysfunction in the negative feed-back between pregnenolone and CB1 ligand in obese subjects. This dysfunction could participate to the hyperactivity of endocannabinoid system saw in obesity.

Outcome Measures

Primary Outcomes (1)

  • Comparison of pregnenolon plasmatic concentration in both groups.

    Pregnenolon plasmatic concentration will be measured at several points.

    Change from 1 hour before lunch to 1 hour after lunch at inclusion day

Secondary Outcomes (2)

  • Comparison of neurosteroid plasma concentrations and endocannabinoid plasma concentrations

    Change from 1 hour before lunch to 1 hour after lunch at inclusion day

  • Comparison of endocannabinoid plasma concentration and pregnenolone plasma concentration

    Change from 1 hour before lunch to 1 hour after lunch at inclusion day

Study Arms (2)

Obese men

EXPERIMENTAL

Measured plasmatic concentration of pregnenolone and endocannabinoid in fasting conditions and over a meal in obese men.

Other: Obese men

Normal-weight men

ACTIVE COMPARATOR

Measured plasmatic concentration of pregnenolone and endocannabinoid in fasting conditions and over a meal in normal-weight men.

Other: Normal-weight men

Interventions

Biological measures before, just before, and after lunch, in obese men

Obese men

Biological measures before, just before, and after lunch, in normal-weight men.

Normal-weight men
