Castela, Inês; Rodrigues, Catarina; Ismael, Shámila; Barreiros-Mota, Inês; Morais, Juliana; Araújo, João R.; Marques, Cláudia; Silvestre, Marta P.; Ângelo-Dias, Miguel; Martins, Catarina; Borrego, Luís Miguel; Monteiro, Rosário; Coutinho, Silvia; Calhau, Conceição; Faria, Ana; Pestana, Diogo; Martins, Catia; Teixeira, Diana (Peer reviewed; Journal article, 2022)Background & aims Although intermittent energy restriction (IER) seems to be as effective as continuous energy restriction (CER) for weight loss, there is still a need to determine the putative effect of this strategy ... -
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. ... -

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 ... -
Metabolic adaptation is an illusion, only present when participants are in negative energy balance
Martins, Catia; Røkenes, Jessica Ann; Salamati, Saideh; Gower, Barbara A.; Hunter, Gary R. (Peer reviewed; Journal article, 2020)Background The existence of metabolic adaptation, following weight loss, remains a controversial issue. To our knowledge, no study has evaluated the role of energy balance (EB) in modulating metabolic adaptation. Obj ... -
Metabolic adaptation is associated with less weight and fat mass loss in response to low-energy diets
Martins, Catia; Røkenes, Jessica Ann; Gower, Barbara A.; Hunter, Gary R. (Peer reviewed; Journal article, 2021)Background: The practical relevance of metabolic adaptation remains a controversial issue. To the best of our knowledge, no study has properly evaluated the role of metabolic adaptation in modulating weight loss outcomes. ... -
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 ... -

Martins, Catia; Dutton, Gareth R.; Hunter, Gary R.; Gower, Barbara A. (Peer reviewed; Journal article, 2020)Weight regain remains the main challenge in obesity management, and its etiology remains elusive. The aim of the present review was to revise the available evidence regarding the “Compensatory Theory,” which is an explanatory ... -
