Could It Be That Diet Sodas Make Us Fat? (http://myhealthoptimizer.com/could-it-be-that-diet-sodas-make-us-fat/)

I think just about everybody who cares about real health these days gets it that most non-sugar sweeteners are bad for you. We know that Aspartameâ„¢, NutraSweetâ„¢ and the rest of those artificial sweeteners destroy health. Most of them lead to horrible diseases, including various cancers, brain tumors and more. And yet we are so concerned about looking too fat, and so obsessed with our appearances that many of us drink diet sodas anyway. We tell ourselves that using artificial sweeteners is the lesser of two evils.

But what if artificial sweeteners do make us fat?
What if they add to the bulge and destroy our health?

I hear you ask, “How can that be? There is no sugar and they have no calories in them.”
The full answer is complex, but I will keep it simple and focus on the essential information you need to understand.
Here’s why diet sodas make you fat: We all know about insulin and that it is secreted by the pancreas. Insulin is required in order for our bodies to metabolize sugar. The more sugar there is in your blood, the more insulin your pancreas needs to secrete so that the sugar can be metabolized. When you don’t have sufficient insulin for the amount of sugar in your blood, that is a form of diabetes, which is a life-threatening health condition.

In addition to being required for your body to metabolize sugar at the cellular level, insulin prompts your body to store available excess calories as fat. This is not a bad thing. We need some fat in order to be healthy.
But problems occur when we have too much insulin so that we store too much fat – we end up packing on the pounds. The problem is compounded because excess insulin stimulates the appetite so that we are compelled to eat more.
This happens even if we don’t really need more food. I say compelled because the chemicals the brain releases to convince us to eat more are overwhelmingly powerful. They are nearly impossible to resist.

At any given time, there is some sugar in your blood stream. Either it is there because you have taken in a food or beverage that has sugar in it, or your body has broken down carbohydrates and converted them to sugar. Again, as long as it is within reasonable limits, this is normal and is not a problem.

The body does its best to secrete the right amount of insulin for the amount of sugar in the bloodstream at any given time. If there is more sugar and insulin than is needed for immediate energy requirements, then the insulin prompts the body to store the excess as fat. If this happens often enough, we can become obese. Look around the U.S. today and you will see that many of us suffer from this problem.

Your brain is the primary control over how much insulin your pancreas releases into your blood stream at any given time. It tries to match the insulin level to the amount of sugar it thinks is in your blood. Having too much insulin causes serious problems. At the very least it leads to obesity. It also leads to insulin resistence, which is a condition in which the cells lose their ability to respond to the insulin. The insulin receptors in the cells get “worn out” and lose their functionality. This is also known as “metabolic syndrome” and is being diagnosed more and more often in the U.S. today.

Having too little insulin also is a problem. It leaves sugar that cannot be metabolized stranded in the blood stream or in intracellular spaces in our bodies. This stranded sugar causes horrendous damage. Look at anyone who has had diabetes for an extended period of time and you will see the kinds of damage that such stranded sugar causes. So to prevent either too much insulin or too little, our brains anticipate the required insulin as we eat. Our brains send an “advance order” to the pancreas so that the insulin is ready when the anticipated sugar enters the blood stream. This fact is critical! Keep it in mind as I add the final pieces to this puzzle.

How does the brain know how much insulin to order? There are taste receptors on your tongue for the basic flavors or tastes that humans can detect. Sweetness is one of these basic flavors or tastes. The sweet taste receptors are located at the back of the tongue.

When anything that tastes sweet comes in contact with these sweet taste receptors, the brain thinks that sugars are being eaten. It tries to determine how much, so it can order the appropriate amount of insulin from the pancreas.
When we eat or drink anything that tastes sweet, the brain will order insulin, even if there is no real sugar and there are no real calories! Just the sweet taste will do it.

That is why almost all artificial sweeteners, and even most natural sugar substitutes lead to over production of insulin.
In fact, many of these non-sugar sweeteners cause far more insulin to be produced and released than a corresponding amount of sugar would. This is because many of these sugar substitutes actually taste much sweeter than sugar. So the brain gets fooled into ordering far more insulin than it would for a corresponding amount of real sugar.

Let’s review the basic chain of events:
1. We drink a diet soda.
2. The artificial sweetener in the soda comes in contact with the sweet taste receptors on the tongue.
3. The brain says, “Oh, we’ve got a bunch of sugar headin’ down the pipe. Better order up some insulin.” It sends an order to the pancreas.
4. The pancreas creates the amount of insulin that the brain ordered and releases it into the blood stream.
5. The amount of insulin is way more than is really needed for the actual amount of sugar taken in. (There wasn’t any real sugar in the soda.)
6. The insulin grabs any available sugars that are not immediately needed for current energy production and stores them as fat.
7. The excess insulin also turns our appetites back on again and we are compelled to eat more food, even if we are not really hungry. *
8. We go buy bigger clothing!
9. We look in the mirror or try on the clothes that fit fine last season and say, “Oh no!” And we go looking for more foods and beverages that have artificial sweeteners in them.

* When we have too much insulin in our blood, our body starts looking for ways to get the sugar it needs to balance out the excess insulin. So it stimulates our appetites to eat more carbohydrates and sweets.

You can see that this is a classic vicious cycle that destroys our health.
Unfortunately, this phenomena occurs even with “natural” sugar substitutes such as stevia and agave sweeteners. Even though these sweeteners do not typically raise the actual blood sugar levels significantly because they do not have much bio-available sugar or many bio-available calories in them, they do raise the insulin levels higher than they should be. Again, when this happens the appetite gets turned on and we are compelled to eat more food – typically far more than we need.
And don’t be fooled by the marketing nonsense about fruit sugars, various forms of fructose and the like. They all lead to this same problem, and many of them are far worse than plain old cane sugar.

So what to do? There are no easy answers. Anything we eat or drink that tastes very sweet is almost certain to cause this problem. Part of the problem is that because the average American diet has become sweeter and sweeter over time we have become accustomed to ever sweeter tastes. It takes some time and effort but we can train ourselves away from the super sweet and back to a more “normal” level of sweetness in our foods and beverages. If we do this our palettes gradually learn to like things that are not quite as sweet.

Also, there is a relatively new, 100% organic sweetener that does not stimulate excess insulin. In fact, it has been very extensively tested and it has no bad health effects at all. On the contrary, it has some interesting health benefits. It is even completely safe for both Type I and Type II Diabetics. A trade off is that it does not taste quite as sweet as most of the artificial sweeteners. But I have found it fairly easy to get used to. I have been using this new sweetener for about a month and the older, sweeter ones that I was using do not even taste good to me anymore. I was using stevia, which now tastes way too sweet to me. The new sweetener is derived from the Acai berry, and it is actually good for you. Actually it is not new in terms of research. It is the result of years of research by and has been through years more of exhaustive safety testing. It is just relatively new on the market.
