Hydration increases cell metabolism

International Journal of Obesity volume 33, page 385 (2009)Cite this article

The recent article by Mathai et al.1 published in the International Journal of Obesity entitled ‘Selective reduction in body fat mass and plasma leptin induced by angiotensin-converting enzyme inhibition in rats’ is very interesting for a number of reasons but perhaps one of the most important is the fact that the treated rats drank twice the amount of water (about 80 ml day−1) as the non-treated controls (about 40 ml day−1). This is a large difference that would have the effect of increasing the flow of water through the body. The authors discuss this point and cite four other studies that have also found increased water intake with renin–angiotensin system inhibition. They suggest possible mechanisms for this enhanced drinking as being due to an increased presence, and thus action, of angiotensin in the brain due to ACE inhibition in the periphery and/or due to urine loss. Both of these are credible physiological mechanisms but they need to be demonstrated.
