Obesity could cause damage than you think, says study

Poor nutrition, insufficient exercise, and an excessive number of pounds on the scale are all factors in lifestyle that increase the risk of metabolic disorders like diabetes.

Obesity could cause damage than you think, says study

Obesity increases the chance of a sugar metabolism imbalance and potentially diabetes. A study group at the University of Basel has recently demonstrated that the contrary is also true: inadequacies in the body`s insulin production contribute to obesity. 

Poor nutrition, too little movement and too many pounds on the scale appears as lifestyle influences the risk of metabolic diseases like diabetes. But the relationship works the other way round as well, as a research group led by Dr Daniel Zeman-Meier of the university`s Department of Biomedicine and the University Hospital of Basel reports. 

If insulin production is compromised, as is the case in the early stages of type 2 diabetes, this can contribute to being overweight. The findings of the study were published in the journal Nature Communications. The research team focused on protease PC1/3, a key enzyme in the body that transforms various inactive hormone precursors into the final, active forms. If this enzyme isn`t functioning properly in a person, the result can be severe endocrine disorders. 

The consequences include a feeling of uncontrollable hunger and severe overweight." Until now, it was assumed that this dysregulation is caused by a lack of activation of satiety hormones, but when we turned off PC1/3 in the brains of mice, the animals` body weight did not change significantly." explains the study`s leader, Dr Zeman-Meier. The researchers concluded from this that something other than a brain malfunction must be responsible. 

Incorrect activation of insulin leads to hunger and overweight their next step, they tested whether overweight could be caused by incorrect activation of other hormones. PC1/3 activates insulin, among other things. 

Insulin plays a key role in the regulation of blood sugar and fat metabolism. "Investigating the role of insulin production as a cause of overweight was obvious," says Dr Zeman-Meier. 

The researchers shut off PC1/3 specifically in the insulin-producing beta cells of the pancreas in mice. The animals consumed significantly more calories and soon became overweight and diabetic. An important mechanism in humans". These results are also interesting because PC1/3 is reduced in the pancreas of patients with prediabetes," says Professor Marc Donath, the research group leader and final author of the study. 

This indicates that incorrect insulin activation could be not only a consequence but also a cause of being overweight. But PC1/3 is also important in the weight regulation of healthy individuals, Donath emphasizes. 

The researchers were able to show that the gene expression of PC1/3 in the pancreas is negatively correlated with body weight in the general population meaning that sufficient PC1/3 promotes a healthy body weight.

The finding that a defect in the insulin-producing beta cells is a trigger of overweight opens up new therapeutic possibilities. For example, it is conceivable that medications could be used to reduce the production of immature insulin precursors, creating a new tool in the fight against overweight and diabetes.
