Coutinho, Sílvia dos Santos Ribeiro Fiandeiro (Doctoral theses at NTNU;2018:53, Doctoral thesis, 2018)Various reviews published over the last decades have shown that several compensatory responses on both sides of the energy balance (EB) equation are activated with weight loss (WL), which oppose the maintenance of a reduced ... -

Appetite suppression during ketogenic diets: Do fecal short-chain fatty acids play a role?

Association between ß-Hydroxybutyrate Plasma Concentrations after Hypocaloric Ketogenic Diets and Changes in Body Composition
Martins, Catia; Nymo, Siren; Aukan, Marthe Isaksen; Røkenes, Jessica Ann; Coutinho, Sílvia; Hunter, Gary R; Gower, Barbara A (Journal article; Peer reviewed, 2023)Background Early studies show that ketogenic diets (KDs) lead to preferential loss of fat mass (FM), whereas preserving fat-free mass (FFM). Additionally, animal data support the anticatabolic effects of DL-3-hydroxybutyrate. ... -
Associations between hedonic appetite, eating behavior traits and weight loss outcomes ten years after Roux-en-Y gastric bypass
Skjølsvold, Oda (Master thesis, 2020)Bakgrunn: Fedmekirurgi er den beste behandlingen for å oppnå et langvarig vekttap. Likevel opplever en gruppe av fedmeopererte et vekttap som ikke er optimalt, og/eller vektoppgang etter vektnedgangen. De nøyaktige årsakene ... -
Associations between the FTO rs9939609 genotypes and insulin sensitivity, glucose tolerance, energy metabolism, appetite hormones, and diet in patients with severe obesity

Assosiasjon mellom ketose og appetittregulering under vekttap, hos personer med fedme
Aukan, Marthe Isaksen (Master thesis, 2019)Introduksjon: Diett-indusert vekttap medfører økt appetitt, med en oppregulering i både sultfølelse og ghrelin sekresjon. Ketogene dietter ser ut til å kunne minimere denne responsen. Målet med denne studien var dermed å ... -
Bariatric surgery versus lifestyle interventions for severe obesity: 5-year changes in body weight, risk factors and comorbidities
Øvrebø, Bente; Strømmen, Magnus; Kulseng, Bård Eirik; Martins, Catia (Journal article; Peer reviewed, 2017)Changes in body weight (BW), risk factors and comorbidities 5 years after Roux-en-Y gastric bypass (RYGB) or different lifestyle interventions are compared.

Changes in hedonic hunger after weight loss induced by diet or sleeve gastrectomy
Brandsæter, Ingrid Øfsti (Master thesis, 2021)Introduksjon: Personer med fedme har en høyere hedonisk appetitt for svært velsmakende mat, og vekttap har vist en reversering av dette mønsteret. Det er imidlertid usikkert om metoden bak vekttap har en uavhengig påvirkning ... -
