About

Background in nutrition and clinical health sciences, with a PhD in Medicine and Health Sciences (obesity and metabolism).
My research focus on how diet, bariatric surgery, physical activity, gut microbiota, and psychological factors influence appetite regulation and body weight. The goal is to identify sustainable strategies for long-term weight loss and weight maintenance.

Research

Exercise, Cardiometabolic Health and Reproduction (EXCAR)

Effects of a high-protein diet and resistance training on fat-mass loss maintenance (PRO-FIT)

Planlagt studie: I PRO-FIT studien skal vi undersøke hvordan styrketrening og et høyt proteininntak påvirker vektnedgang, vedlikehold av muskelmasse, metabolisme, appetittregulering og livskvalitet.

Effect of diet-induced weight loss versus Sleeve Gastrectomy and Roux-en-Y Gastric Bypass on appetite (DISGAP)

Ferdig studie: Vi har undersøkt hvordan vekttap med diett og fedmekirurgi påvirker spiseadferd, belønningssystemet og appetitt-relaterte hormoner.

Smart Nutrition, Healthier Communities: A Digital Therapeutic Strategy for Early Obesity Intervention

Ferdig studie: Prosjektet undersøker effekten av digitalterapeut (DTx) og digitalt oppfølgingsverktøy i Frisklivssentralen Værnesregionen, og retter seg mot tidlig intervensjon for overvekt og fedme.
