If you are not drinking a minimum of 2 litres of water per day plus an extra 750 ml for every workout then you are slowing down your metabolic rate. Your liver is the organ that deals with metabolising fat, and your kidneys deal with straining the toxins out of your body.

However, if you do not have enough water in your system, your kidneys are not able to do their job effectively and your body shifts some of your kidney’s load over to your liver. This lowers your liver’s productivity and ability to metabolise fat quickly and efficiently.
