7.  blood pressure hormone can cause weight gain
Uncovering new strategies to fight obesity is a key focus for researchers, given that the condition is a growing public health concern.

Now, a new study sheds light on how the renin-angiotensin system – the hormone system that regulates blood pressure – may also promote excess weight gain. The discovery offers a potential target for obesity treatment.  Researchers reveal how a hormone system that controls blood pressure may also cause weight gain. Senior study author Justin Grobe, Ph.D., assistant professor of pharmacology at the University of Iowa, and colleagues published their findings in the journal Cell Reports. While the role of the renin-angiotensin system (RAS) in blood pressure control is well established, previous studies have indicated the RAS is also involved in energy balance and metabolism, suggesting the hormone system influences weight. According to Grobe and colleagues, whether RAS promotes weight gain or weight loss depends on where in the body it is active. For example, if the RAS is highly active in the brain, it increases energy expenditure by boosting resting metabolism, which leads to weight loss.
