About the thesis

The prevalence of obesity across the world has increased dramatically in recent years, thus increasing the prevalence of obesity-associated diseases, such as type 2 diabetes and cardiovascular disease. Obesity is considered a complex and multifactorial condition, affected by interactions between environmental and genetic factors.

The overall objective of this thesis was to investigate how genetic variants, circulating microRNAs, and dietary fibres affects obesity and weight loss. More specific, the role and potential genetic regulation of angiopoietin-like protein 3 was investigated in relation to body weight, lipid metabolism and liver health before and during a low-calorie diet in the DiOGenes study.

Furthermore, it was investigated whether a diet supplemented with dietary fibres would induce greater body weight loss compared to placebo during energy restriction in an overweight/obese population in the My New Gut II study and whether the fibre-containing dietary supplements would affect the gut microbiome, lipid profile, and glucose metabolism.

Finally, selected circulating miRNAs was analysed in response to weight loss and the potential of these circulating miRNAs as biomarkers of the metabolic syndrome was investigated.
