The Importance Of Drinking Water For Health & Weight Loss

Water is such an important part to a healthy, happy human body and it’s a safe bet you’d benefit from increasing your intake, from both a health and weight loss perspective. This is one of the simplest yet most beneficial changes you could make to your diet if you haven’t already started.

Water is considered to be one of the most, if not the most important nutrient in the body. Our bodies are made up of approximately 60-65% water, with muscles about 75%, blood about 82% and the lungs being 90% water.

Every cell of your body is composed of water. You need it to carry nutrients, blood and oxygen all around your body. You can survive indefinitely without carbohydrates, you can live for a while without proteins and fats, but go without water for a few days and you won’t last long. This goes to show how vital water is to good health and it’s no surprise your physical performance, as well as your ability to use nutrients to build and repair your body is totally dependent on your level of hydration.

Water is important for everybody but for those of us who exercise consistently and generally like to keep active, it is even more important. You actually lose water throughout the day even when you’re not active; it is used just to breath, to sweat, to digest food and in your bodily waste functions. It’s just that during exercise and recovery, your body uses up far more water than that of a sedentary inactive individual.

Dehydration will also affect your ability to exercise effectively and with adequate intensity to get results. If you dehydrate your muscle by only 3%, you cause about 10% loss of muscle strength. If you are regularly exercising you want to train to your maximum potential every time and better your previous performances. This is how we improve and progress and get results. If you’ve lost 10% of your muscle strength there’s no way you’re exercising to your potential. When you look at the impact dehydration has on just our physical performance alone, it’s clear to see staying hydrated is so important if we want to optimize our weight loss and fitness levels.

Just drinking more water will actually help with weight loss for many people, more specifically, the metabolism of fat.  This is actually something that the liver does when it converts stored fat to energy. The liver has other functions but this is one of its main jobs. Unfortunately, another of the liver’s duties is to help out the kidneys, which need plenty of water to work properly. If the kidneys are water-deprived, the liver has to do much of their work along with its own, lowering its total productivity. It therefore can’t metabolise fat as quickly or efficiently as it could when the kidneys were pulling their own weight. If you allow this to happen, you not only might be doing some damage to your liver, but you’re also setting yourself up to store more fat.

There are so many other things that can be spoken about when it comes to the importance of drinking water; these are just some of the more relevant ones when it comes to our weight loss & fitness goals. Try to drink about 2-3 litres of water a day, and add about a litre per hour of exercise you do and see if it helps you to feel better and reach your weight loss & fitness goals.
