Central and peripheral mechanisms involved in dietary fat intake and obesity

LSU New Orleans School of Medicine


Dr. Primeaux received her PhD in Biopsychology from the University of Georgia in 2000, where she studied behavioral and molecular aspects of depression in animal models. In 2003, Dr. Primeaux joined the Pennington Biomedical Research Center as a post-doctoral fellow and began studying animal models of obesity. During this time, she was also awarded a Post-doctoral Fellowship Award from the National Institute of Alcoholism and Alcohol Abuse to examine the role of anxiety-related behaviors on alcohol preference. In 2010, Dr. Primeaux joined the faculty at Louisiana State University Health Sciences Center-School of Medicine and is a member of the Joint Diabetes, Endocrinology & Metabolism Center between LSUHSC-NO and Pennington Biomedical Research Center. Dr. Primeaux focuses on pre-clinical and clinical studies relating to central and peripheral mechanisms involved in dietary fat intake and obesity. She has over 25 publications and has received funding for numerous preliminary studies.

Ongoing research projects related to diabetes obesity

Dr. Primeaux’s laboratory focuses on animal models of obesity and obesity-resistance, dietary fat sensing mechanisms, hypothalamic neurochemistry controlling dietary fat intake and fat and carbohydrate metabolism.

Ongoing projects include

  • The regulation of the hypothalamic neuropeptide, QRFP, by estradiol and QRFP’s effects on dietary fat intake in females.
  • The role of QRFP on macronutrient selection in males.
  • The effects of bariatric surgery on food preferences.
  • Role of orosensory detection of fat in the susceptibility to obesity.
  • Determinants of the susceptibility to obesity and metabolic flexibility.
