We explain how the identification of novel obesity predisposing genes has clarified unsuspected biological pathways involved in the control of energy balance that have helped to understand past human history and to explore causality in epidemiology. Many digestive diseases are related to systme. Cell suspensions were prepared from MAT and colon tissue. A majority of obesity loci identified by GWAS studies do not harbor genes with clear connections to the biology of body weight regulation [ 12 ], reflecting our limited understanding of the biology of obesity in contrast with other complex traits such as autoimmune diseases or lipid levels. In fact, it seems that many disease-associated variants are not yet identified prospects for risk prediction, but may improve if more disease predisposing variants are included in the models [ ]. Germfree mice are largely protected against obesity 42 ,

In fact, to synopsize microbiota variation into three discrete clusters would imply that these enterotypes are relatively stable over time, a situation that is not true for healthy subjects where enterotypes are highly variable over time [ 51 ]. Obesity is often described as a chronic state of low-grade inflammation 1617 Schnabolk, G.

A telephone-based lifestyle interventions led to significant weight loss that systeem still evident at 24 months, without adverse effects on quality of life, hospitalizations, or medical events.
