Drinking Water Increases Fat Oxidation

I am sure you have heard or read the weight loss tip of drinking water to help you lose weight.  Well, for most of us the reason for drinking water was to help feel fuller faster so we ate less calories.  

Also, if we drank water instead of caloric beverages we would consume less calories, which may lead to weight loss.  There were also the critics that may have told you this was ridiculous and you were wasting your time drinking water as a tool for greater weight loss.  

Well, there is some pretty solid evidence that says this is not ridiculous at all and the studies conducted on this have been some of the more rigorous studies conducted with crossover experiments and randomized and controlled trials.  

In various crossover experiments drinking water resulted in lower total caloric intake with the subjects that were tested.  The reason for this is simple and it is because they were not consuming calorie filled beverages.  They were replacing these caloric beverages with water that has zero calories.  

What was also found was that the individuals do not eat less food when they know they are drinking caloric beverages.  They still eat the same amount of calories regardless of if their beverages contained calories or not.

Drinking Water Increases Fat Oxidation

Fat oxidation is at its greatest when your insulin levels are low.  The reason for this is because insulin inhibits or decreases the ability of rate limiting enzymes that breakdown triglyceride fats into free fatty acids.  As well as the transport of these free fatty acids into the mitochondria and Krebs cycle to be burned for energy.  

Since water does not contain calories or carbohydrates  like over beverages it does  not trigger an insulin response.  If you were to compare it to the glycemic index water is of course 0, milk is around 35, juice is around 50 and sugary drinks are as high as 80.  

Keeping your insulin levels lows results in greater rates of fat oxidation.  Now remember this doesn't apply just to water.  The foods you eat and what combination of nutrients you eat can all influence the insulin response.  Keeping your insulin response consistently lower throughout the day will allow your body to burn more stored fat as energy.

Anytime your insulin and blood sugar levels are elevated you stop fat breakdown and fat oxidation.

There have been decades of crossover studies that consistently show higher levels of fat oxidation when drinking water compared to caloric drinks before or during low to moderate exercise.  If you look at the average of these studies the fat oxidation is around 40% greater after water is consumed than after a caloric beverage.  

It is normal for fat oxidation to be depressed for a length of time after a meal because naturally your body is going to release insulin to properly utilize the nutrients you just consumed.  What you choose for your beverage though can dictate how long that slow down of fat oxidation really is.  

Research has shown that drinking water instead of a caloric beverage can restore the rate of fat oxidation to pre-meal levels about 2 hours sooner than if you were to drink a caloric beverage with the same meal.  

Some studies have shown that consumption of 500-600 calories from carbohydrates can depress fat oxidation for 6 hours after consumption.  

Hypocaloric Diets and Water Leads To Weight Loss

Two very interesting intervention studies looked at a hypocaloric diet and then the same diet plus water as the beverage.  One study looked at 48 randomized  overweight or obese men and women.  They were given a hypocaloric diet plus 500ml of water at each meal or they were just given the hypocaloric diet (control) with no water.

The results showed that weight loss in the water group was 2kg greater.  In analysis of data from the Stanford A to Z Study they focused on 155 overweight premenopausal women who reported drinking less than 1L/ day of water before beginning 1 of 4 different weight programs.  The programs were the Atkins diet, Zone diet, LEARN diet,  and Ornish diet.  The 4 programs do recommend  drinking 1L/day of water or more and limiting or no intake at all of caloric beverages.  

After 2 months of their diet classes they all reported higher water intake and less caloric beverage intake.  Independent of any changes in diet or physical activity those who increased their water intake and decreased caloric beverage intake had significantly greater weight loss.  

Water And Metabolic Syndrome

Surprising new research from the University of Colorado shows that drinking water alone may redue the incidence of Metabolic Syndrome, also know as MetS.  This syndrome, which may precede Type 2 diabetes, is highlighted by high blood pressure, cholesterol, and weight carried around the belly.

The latest results, however, show that drinking water--and not fructose-sweetened beverages--may lose more fat by reducing levels of vasopressin.  Vasopressin is a hormone released from your brain that increases water retention, which leads to dehydration by storing more water as 'metabolic water.'  The researchers discovered that being dehydrated often leads to weight and body fat gain.

By drinking water, however, you may lower vasopressin levels, therefore you may be able to lose weight and stay hydrated at the same time.  This also reduces the amount of 'metabolic water' stored in your fat, which could also lead to weight loss.

Summary

Ok, lets summarize all this data as some of it may have gotten confusing.  

Drinking water during the day and at your meals instead of drinking calorie filled beverages decreases your total calorie intake and it also promotes greater fat oxidation, which is the burning of stored fat as energy.  

So drink water at meals  and in-between meals instead of calorie filled beverages.  Take your Prograde Metabolism so you are consuming scientifically proven nutrients that boost your metabolism and help to control blood sugar and insulin levels.  Finally, eat a higher protein rich and lower carb diet to minimize the insulin spikes that will depress fat oxidation for hours after that meal.
