The honest truth is that there is no quantifiable answer to this question. There simply isn't the data out there to answer such a multi-faceted and complicated question. We can give you statistics on individual supplements and their effect on single component of health, but that isn't nearly as convincing.
What we tend to do is use our own anecdotal experience and go from there. Due to the non-scientific nature of this evidence we can't give you a cast iron guarantee of the quantitative benefit of any programme. All we can tell you is that we have had great success in the past and that those who take the supplements we recommend experience better results than those who don't.
So with that in mind, what if I were to tell you about a free fat loss supplement? Sounds like a no brainer, according to the motivation formula zero cost means an infinite benefit ratio! The supplement I'm talking about tastes great, allows your body to function optimally and is totally free, of course it's good old water.
Water works in a number of ways, primarily and most importantly it allows your body to do what it needs to do. That means everything is dependent upon hydration levels for efficiency. Training intensity, digestion, cardiac health, detoxing just a few incredibly broad areas which are dependent on the blue stuff.
In appreciate that outlining that your body needs water to function is not ground breaking insight so I've lined up some more interesting reasons:
Water is less salty than your blood, when you consume it, energy is required to balance that out so it can be absorbed. A study conducted in 2003 found that drinking 500ml of water induced a 10-40 minute increase in metabolic rate. This means that for the time immediately following ingestion of water more calories are being burned than when you're thirsty, and because it is probably at rest a very high percentage of the energy used will be fat.
Water also reduces appetite, people confuse thirst with hunger and so overeat to compensate, researchers found that short term, those who consumed water before a meal would consume less food. Another win.
Here's the best till last, maintaining hydration long term results in a change in your hormone balance. You reduce the amount of fat tissue in your body, increase your insulin sensitivity and increase the ratio of fat used in the body for energy.
Now we're talking
Now we're talking
So, maintain hydration by ensuring that your urine is clear. Focus particularly on drinking in the morning, when you are likely most dehydrated, winding down consumption before bed so as not to interrupt sleep.
