Influence of a complex weight reduction methodology on body composition, cardiovascular fitness and quality of life in obese people. V Panayotov, Petkov, Palatova, Bonova, Yordanova. Obesity Facts 2014;7(suppl 1):118–119. http://www.karger.com/Article/Abstract/363668 (open access)
It was established in this study that after 8 months of follow-up, a diet based on our Eurodiet products was more effective than a conventional diet in terms of weight loss and lean mass spared. Although adding anaerobic physical training has cardiovascular benefits, this form of exercise alone does not induce weight loss.
Non-Alcoholic Fatty Liver Disease (NAFLD) in Obese and Cardiometabolic Risk Factors. K Komshilova, E Troshina. Obesity Facts 2014;7(suppl 1):162–163. http://www.karger.com/Article/Abstract/363668 (accès libre)
Non-Alcoholic Fatty Liver Disease (NAFLD) is associated with several markers and cardio-metabolic risk factors contributing to type 2 diabetes, such as dyslipidemia, insulin resistance, changes in glucose metabolism and high levels of C-reactive protein (CRP) and PAI-1. The frequency and the severity of cardio-metabolic problems increase with the evolution of this form of fatty liver disease.
Protein, carbs and fats in personalized weight control – efficacy, effectiveness and safety. Longitudinal changes in peripheral neurotransmitters levels after dietary restriction in subjects suffering from metabolic syndrome.

Subjects with metabolic syndrome followed a diet restricting their energy intake by 30% for 6 months. Their weight loss was paralleled by a significant increase in their dopamine and serotonin blood levels (+18% and +16%, respectively). These increases were also associated with a decrease in the subjects’ carbohydrate intake and the consumption of fewer calories.
The impact of speed of weight loss on body composition and compensatory mechanisms activated during weight reduction. Coutinho, With, Kulseng, Truby, Martins. Obesity Facts 2014;7(suppl 1):77. http://www.karger.com/Article/Abstract/363668 (open access)
Whether the 9% weight loss achieved by obese subjects was fast (within 4 weeks) or more gradual (within 8 weeks), the same amount of weight was lost and the same changes in body composition occurred in both cases. However, although gradual weight loss prevents Reduced Resting Metabolism (RRM), fast weight loss is more conducive to physical exercise and has more positive effects on subjects’ feelings of hunger and their craving for food (both of which were significantly reduced).
Protein, carbs and fats in personalized weight control: efficacy, effectiveness and safety Arne Astrup. Obesity Facts 2014;7(suppl 1):3. http://www.karger.com/Article/Abstract/363668 (open access)
To lose weight, it does not suffice to reduce one’s energy intake. The protein, carbohydrate and lipid content of diet also play an essential role because calories do not all have the same effects on satiety and thermogenesis. The results of the randomised trials conducted here show that the protein to carbohydrate ratio and the glycemic index of carbohydrates have decisive effects on people’s spontaneous energy intake and improve the success of their weight control efforts and the severity of the cardio-metabolic risk factors present.
