Monitoring fiber and protein intake in obese clients of a nutrition counseling center
Kekrtová, Magdaléna ; Pejšová, Hana (advisor) ; Weidenthalerová, Edita (referee)
The obesity epidemic is still a very topical problem and requires a comprehensive therapy that includes nutritional counselling. In my practical experience, the topic of protein and fibre tends to be very common with obese clients and I often observe less than appropriate choices in terms of protein sources. Fibre is not given much importance and therefore its adequate intake is not optimal. Therefore, the theoretical part aimed to summarize the current knowledge about obesity, protein and fibre. However, nutrition in obesity is summarised in a comprehensive way, taking into account other nutrients, but also micronutrients or drinking, which may also be significantly related to obesity. The theoretical summary of obesity was summarized rather marginally. In terms of treatment approaches, diet therapy, physical activity or psychotherapy are more approached. The importance of the nutritional therapist is not neglected. The practical part was quite comprehensive. The aim of the study was to assess dietary habits (qualitatively and quantitatively, focusing mainly on protein and fibre), body composition before and after the nutritional intervention and thus to evaluate the effect of the therapy. It was also intended to provide information on the original dietary habits of obese individuals in terms of...

Prebiotic sweetener tagatose
Jurečková, Zuzana ; Vránová, Dana (referee) ; Vespalcová, Milena (advisor)
This sweetener, D-tagatose, has numerous advantages, which would eventually be able to use in the food industry. It summarizes the properties of Dtagatose, physical and also chemical, the possibility of production from lactose or bacterial action on Dtalitol. The basic information about the properties of Dtagatosy also discusses the actual metabolism of Dtagatose, prebiotic properties and their effect in the gastrointestinal tract. Dtagatose is a proposed new sweetener, because the possibility can not be missed in certain applications tagatose in a different types of foods for example confectionery. And positive qualities in comparison with sucrose. This comparison is made to examples of disease associated with excessive use of conventional sweeteners sucrose. This paper also discusses possibilities Dtagatose determination in foods by different methods.

Kvantitativní zastoupení bakterií rodu Lactobacillus v lidském zažívacím traktu v závislosti na změně stravovacích návyků
Kolísková, Kateřina
This diploma thesis deals with the issue of quantitative representation of the bacterial family in the human digestion system depending on changes in eating habits. The start of literary digest addresses general characteristics of digestion microbiome and its bacterial represen-tation. The most comprehensive part belongs to individual factors, who influenced overall number of bacterial species inhabiting the digestion microbiome. The last chapters of the theoretical part belong to cultivative and molecular biological methods, which are used in examination of the human digestion tract. Experimental part focuses on differences in the number of individual bacteria in the samples of human excrements, whose presence was determined by cultivative methods. Isolation of bacterial DNA was performed, which was subsequently confirmed by polymerase chain reaction. In resulting values, we observed small changes (p < 0,05) in bacterial species L. acidophilus a L. rhamnosus at the end of the second period. All bacterial families, except Bacteroides, had downward tendency (p > 0,05). Based on acquired data from food records, we observed changes in consumption of basic macronutrients (protein, fat, carbohydrates) and fiber. Only in carbohydrates and sim-ple sugars, we observed statistically provable differences (p > 0,05). Final analysis proved that changes in eating habits did not influence the total number of bacterial species inhabiting digestion microbiome.

Psychological Aspects of Obesity
Mašková, Eva ; Kebza, Vladimír (referee) ; Šivicová, Gabriela (referee)
The aim of this thesis "Psychological Aspects of Obesity" is to summarize psychological findings of causes and consequences of obesity, the most common health problem in the world. This thesis extends the topic of the diploma thesis entitled "The Psychological problems of Obesity." The theoretical part deals with many key issues of obesity, from definition through the epidemiology, etiology and obesity prevention and treatment. However the main topics of this thesis are the psychological characteristics associated with obesity. It includes personality factors of obese people, willpower and self- control and specific psychopathology. The research part of this thesis is mapping the occurrence of a specific psychopathological phenomena focusing on the emotional eating disorder, night eating syndrome, binge eating and symptoms of eating disorder. A total of 80 participants who were diagnosed with obesity, combined I. - III. class, attended educational- recondition stay organised by Third Internal Clinic of The General University Hospital in Prague and University Physical Educational Unity. Applied methods were "Eating Behavior and Emotionality Questionnaire" (JICHEM), "The Eating Disorder Examination Questionnaire 6.0" (EDE - Q) and "The Night Eating Questionnaire" (NEQ). The data of quantitative...

Interplay between ghrelin and its novel endogenous antagonist LEAP2: possible role in the pathology of obesity
Holá, Lucie ; Maletínská, Lenka (advisor) ; Jurčovičová, Jana (referee) ; Malínská, Hana (referee)
The increasing number of overweight and obese individuals has become a major health issue in our society. The etiology of obesity often involves excessive hyperphagia, highlighting the importance of comprehensive understanding the regulation of food intake regulation in order to effectively treat this chronic condition. Ghrelin, a peripheral peptide hormone responsible for increasing food intake, directly affects the hypothalamus through the growth hormone secretagogue receptor (GHSR). Recently, it was found that liver expressed antimicrobial peptide 2 (LEAP2) naturally counteracts the effects of the GHSR as an inverse agonist. This makes LEAP2 a potential candidate for the development of anti-obesity treatment. This thesis explores the interaction between ghrelin and LEAP2 in the context of food intake regulation and obesity. Firstly, it focuses on modified N-terminal peptide LEAP2(1-14) and its lipidized analogs, examining their affinity to and activation of GHSR in vitro and in vivo. The results demonstrate that palmitoylated LEAP2(1-14) (palm-LEAP2(1-14)) exhibits the most pronounced affinity for GHSR, acts as GHSR inverse agonist, reduces food intake, inhibits growth hormone release, and shows increased stability in rat plasma. These findings suggest that palm-LEAP2(1-14) holds promise as an...
