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 ... -
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 ... -

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 ... -
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 ... -
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 ... -
Iodine status and iodised salt consumption in portuguese school-aged children: The iogeneration study
Leite, Joao Costa; Keating, Elisa; Pestana, Diogo; Fernandes, Virginia Cruz; Maia, Maria Luz; Norberto, Sonia; Pinto, Edgar; Moreira-Rosario, Andre; Sintra, Diana; Moreira, Barbara; Costa, Ana; Silva, Sofia; Costa, Vera; Martins, Ines; Mendes, Francisca Castro; Queiros, Pedro; Peixoto, Bruno; Caldas, Jose Carlos; Guerra, Antonio; Fontoura, Manuel; Leal, Sandra; Moreira, Roxana; Carvalho, Irene Palmares; Lima, Rui Matias; Martins, Catia; Delerue-Matos, Cristina; Almeida, Agostinho; Azevedo, Luís; Calhau, Conceição (Journal article; Peer reviewed, 2017)The World Health Organization promotes salt iodisation to control iodine deficiency. In Portugal, the use of iodised salt in school canteens has been mandatory since 2013. The present study aimed to evaluate iodine status ... -
Longer Length of First Stay in Intermittent Residential Programmes Is Associated with Larger Weight Loss at 1 and 2 Years
Martins, Catia; Strømmen, Magnus; Kulseng, Bård (Journal article; Peer reviewed, 2013)Objective: To determine if length of first stay impacts on weight loss and cardiovascular fitness, at 1 and 2 years in severely obese patients enrolled in intermittent residential programs. Methods: In a retrospective ... -
Obesity Knowledge amongst final year medical students in Norway
Martins, Catia; Norsett-Carr, Anette (Journal article; Peer reviewed, 2017)Objectives: To assess the level of obesity knowledge in final-year medical students in Norway and to compare it to an expert group and first-year medical students. Methods: A 20-item questionnaire was specifically designed ... -
Predictors of success after a 2-year lifestyle intervention for morbid obese patients at Røros Rehabilitering Center
Hveem, Ida; Olsen, Eirik (Master thesis, 2015)Background: Lifestyle treatment can produce good short-term results in the treatment of morbid obesity, but relapse is a common problem. Therefore it is important to identify predictors of longterm success after lifestyle ... -
