B11 - Identification of molecular classifiers and casual drivers determining the personal response to dietary intervention trials

Project B11 will combine multidisciplinary expertise of large-scale interventional studies, molecular epidemiology and bioinformatics to identify and validate molecular classifiers related to the short and long-term outcomes of dietary interventions including weight reduction and obesity sequelae on an individual level. This will help to distinguish between patients likely profiting from dietary interventions and those requiring other types of interventions such as drug treatment. Going beyond associative relationships, we aim to establish comprehensive causal mechanistic chains of dietary intervention, induced molecular response, resulting weight reduction, and finally, long-term clinical outcomes (obesity sequelae). These causal chains provide new strategies for therapy surveillance and new therapy targets.

Figure 1. Dynamics of human fat depots/deposits during 18 months of intervention. MRI illustration of the human fat depots/deposits at baseline and after the 18-month intervention following moderate weight loss (6%): (I) Abdominal fat - visceral fat (green), deep SAT (light blue), superficial SAT (blue), non-classified fat (red), peri-muscular fat (purple); (II) Intra-hepatic fat; (III) Cardiac fat - of intra-pericardial fat (IPF, light blue) and a similar reduction of extra-pericardial fat (EPF, purple, n=80 for the cardiac sub-study); (IV) Pancreatic fat (red); (V) Renal sinus fat (blue); (VI) Femur intramuscular fat (green).
