Insulin And Weight Gain

Maybe the title of this post should be about how SUGAR makes you fat, not insulin, but hey, we’re not looking to point fingers here.  I’m just looking to fill you in on the mechanism of insulin and weight gain, and how those high glycemic index carbs make you fat.

So the first thing that happens is, you eat a big ol’ pile of sugar.  Or bread, or whatever other carbs of choice you want to blame for that bulge in your belly.  Since refined carbohydrates have very little fiber, or filler material, that sugar very very rapidly gets digested and assimilated into your bloodstream.  Unrefined carbs, of course, have a much more muted effect, but with refined carbs you’re basically mainlining sugar.

The immediate effect of this is to dramatically spike the level of sugar circulating in your bloodstream.  As a consequence, your body then releases a massive surge of insulin, which is the hormone the body uses to clear sugar out of the bloodstream.  The more sugar in the blood, the more insulin gets released.

Here’s where we run into the first problem.  High levels of insulin signal the body to store and keep fat.  You’ve essentially just shouted at your stomach, STAY FAT, NO MATTER WHAT.  This holds true regardless of caloric intake.  In the presence of high levels of insulin, your body will not burn fat– instead, it will start to break down muscle and burn that instead.

You may have encountered this already.  Ever starve yourself like crazy trying to lose weight, and nothing happens?  You were probably eating refined carbs of some sort (when you did eat), and therefore signalled your body to hang on to that fat for dear life.  You probably got sluggish and cranky, but not thin.

There’s more.  Insulin is an antagonist to Human Growth Hormone (HGH) and glucagon, another hormone.  What’s an antagonist?  What it sounds like… it essentially means that insulin blocks or inactivates HGH and glucagon.

So, why should you care?  Well, glucagon is a hormone that tells your body to burn off fat, so I bet you care about THAT.  And HGH not only tells your body to burn fat, it also tells the body to put on lean muscle mass (which increases metabolism and therefore burns off even more fat).

If it sounds like a double whammy, it is.  Insulin itself makes you store fat, and shuts down the hormones that tell you to burn if off.  Bummer, right?

I’m not finished.  Insulin also makes you hungry.  You see, as your blood sugar spikes, your body over-reacts and dumps tons of insulin into your system, which does its job and clears out all of the blood sugar.

As in, ALL of the blood sugar.  So after you spike your blood sugar up, it comes crashing back down.  This is why, after you binge on carbs, you get that sugar rush followed by a huge crash of energy… and a desire for more carbs.  As your blood sugar drops, your energy levels drop along with it.  And, as your body senses a dramatically low level of blood sugar, it gets desperate for exactly that… more sugar.

Kind of a mess, isn’t it?  Plus, refined carbs don’t have any of the fiber to tell your stomach to feel full, so you gobble down tons of the stuff and still feel like eating.  So, let’s sum up:

• You eat a ton of calories but don’t feel full.
• You spike your insulin levels and tell yourself to stay fat.
• You deactivate the hormones that tell your body to burn fat.
• You have a huge energy crash coupled with a fierce desire for more carbs.

Practically makes you think that sugar should be illegal, doesn’t it?  But remember, ANY refined carbohydrates are going to have this effect.  The higher the glycemic index (how sugary the food is), the worse the effect (i.e, the greater the insulin and greater the weight gain).  Quantity of carbs consumed is another obvious factor.

Is it any wonder why I tell people to avoid this stuff?  Refined carbs are practically poison, my friends. As an extra added bonus, there’s some research suggesting spiking insulin levels are a contributing factor to aging. Remember I said it deactivates HGH?  HGH is the hormone that keeps us young (just ask Sylvestor Stallone, he got caught going into Australia with about a million vials of the stuff).

Switch over to a whole foods diet, avoid the carbs, and stay thin and young.  It’s just that simple.
