An investigation of potential variables affecting the physiological adaptations to weight loss: weight loss rate, nature of energy restriction, and ketosis
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?
Stakvik, Karina (Master thesis, 2021)Introduction: Ketogenic diets (KDs) have the ability to suppress the increase in appetite otherwise seen with diet-induced weight loss (WL). The exact mechanisms involved remains unknown, but changes in gut microbiota ... -
Association between Energy Intake, Macronutrient Distribution, Intake of Different Food Groups, Meal Frequency, Physical Activity and Weight Loss Outcomes Ten years after Roux-en-Y Gastric Bypass
Lundanes, Julianne (Master thesis, 2020)Bakgrunn: Fedmekirurgi er den mest effektive langtidsbehandlingen for sykelig fedme og dens komorbiditet. Det har vist seg at opp til 20-30% av de som gjennomfører fedmekirurgi opplever suboptimalt vekttap (SWL) innen de ... -
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 ... -
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. A total of 209 (75% women) severe obese adults were non-randomly ... -
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 ... -
Compensatory mechanisms activated with intermittent energy restriction: a randomized trial
Coutinho, Silvia dos Santos Ribeiro F; Halset, Eline Holli; Gåsbakk, Sigrid; Rehfeld, JF; Kulseng, Bård Eirik; Truby, H; Martins, Catia (Journal article; Peer reviewed, 2017)Background & aims Strong compensatory responses, with reduced resting metabolic rate (RMR), increased exercise efficiency (ExEff) and appetite, are activated when weight loss (WL) is achieved with continuous energy ... -
Effect of Aerobic Exercise Intensity on Energy Expenditure and Weight Loss in Severe Obesity-A Randomized Controlled Trial
Berge, Jarle; Hjelmesæth, Jøran; Hertel, Jens Kristoffer; Gjevestad, Espen Svendsen; Småstuen, Milada Cvancarova; Johnson, Line Kristin; Martins, Catia; Andersen, Eivind; Helgerud, Jan; Støren, Øyvind (Peer reviewed; Journal article, 2021)Objective This study aimed to compare the effects of two aerobic exercise programs of different intensities on energy expenditure. Methods This was a single‐center randomized controlled trial of patients with severe obesity ... -
Effects of a similar weight loss achieved by sleeve gastrectomy or a very low energy diet on homeostatic appetite markers
Skårvold, Silje (Master thesis, 2021)Introduksjon: Bariatrisk kirurgi (sleeve gastrektomi (SG)) har fram til nå vist seg å være den mest effektive behandlingen for fedme. Det er blitt antatt at langsiktig suksess kommer fra de gunstige endringene i det ... -
High-intensity interval training, appetite, and reward value of food in the obese
Martins, Catia; Aschehoug, Irina; Ludviksen, Marit Krey; Holst, Jens; Finlayson, Graham; Wisløff, Ulrik; Morgan, Linda; King, Neil; Kulseng, Bård Eirik (Journal article; Peer reviewed, 2017)Purpose Studies on the effect of chronic interval training on appetite in the obese population are scarce. The aim of this study was to determine the effect of 12 wk of isocaloric programs of moderate-intensity continuous ... -
Investigating the effect of sex and ketosis on weight-loss-induced changes in appetite
Lyngstad, Anna; Nymo, Siren; Coutinho, Silvia; Rehfeld, Jens F.; Truby, Helen; Kulseng, Bård Eirik; Martins, Catia (Peer reviewed; Journal article, 2019)Background Diet-induced weight loss (WL) is usually accompanied by increased appetite, a response that seems to be absent when ketogenic diets are used. It remains unknown if sex modulates the appetite suppressant effect ... -
Investigation of the long-term sustainability of changes in appetite after weight loss
Nymo, Siren; Coutinho, Silvia dos Santos Ribeiro F; Vestbostad, I.; Kulseng, Bård Eirik; Martins, Catia; Truby, Helen; Rehfeld, Jens Frederik (Journal article; Peer reviewed, 2018)Background/Objective Diet-induced weight loss (WL) leads to a compensatory increase in appetite and changes in the plasma concentration of appetite-regulating hormones are likely to play a role. Whether these changes are ... -
Investigation of the role of carbohydrate intake on gut microbiota and short-chain fatty acids
Nerhoel, Kari (Master thesis, 2021)Bakgrunn: Ketogene dietter har stadig økt i popularitet de siste årene, antakelig fordi de har vist at de kan føre til vekttap, samtidig som de forebygger en økning i appetitt som vanligvis forekommer ved vektreduksjon. ... -
