In the last 50 years obesity rates in America have 4Xed, climbing to over 40% of the population. As this causes much more than just “cosmetic” issues it’s time to see why this is happening and what we can do about it.
This is the first article in a series on Insulin, Insulin Resistance, Sugar and Body Fat, as a well as an overall series on hormones, so stay tuned!
Yes, about 90% of what most of us consider as body fat is made by and from sugar.
But probably not how you think.
And it has a lot more to do with the type of sugar it is and, more specifically, how it affects your hormones (messenger chemicals that tell your body how to use the food you put into it).
Because it’s your hormones that will determine what will ultimately happen with this sugar and whether or not it will be used to make new body fat.
Now, before you get scared and think: “Oh no, this is another low carb rant!”
We actually found in the beta trials for our Fat Loss & Lean Bulk Program that as long as the carbs (sugars) were natural carbs, people can lose fat and lean out just as well on higher carbs as on higher fat.
It’s processed sugars that mess everything up. But we’ll get into how that works further on.
First, let’s break down what actually happens when we consume carbs and what hormones come into play here.
Now, when we think of “gaining fat” or “being overweight” we’re not talking about the fat that makes up 50% of each of our cells and must be there for our survival.
No, we’re talking about the fat under our skin and stored in our fat cells which exist only as fat storage centers. This is about 90%-95% of what we think of as our “body fat”.
But this fat isn’t just made of fat. It's a very specific type of fat (there are many) made of part sugar and part fatty acid and looks a bit like a tadpole with a sugar head and three tails made from chains of fatty acids.
This three-tailed tadpole of a fat is called a Triglyceride.
Glyceride refers to the sugar head and “Tri-” is for the three fatty acid tails.
These Triglycerides are the fats stored in your fat cells and what you’re trying to keep off your body if you want to be lean.
(They can also be stuck to the walls of your blood vessels or shoved in between cells in your organs, causing high blood pressure, heart disease, and organ trouble. But that’s another article).
But no matter where they are, triglycerides require both the sugar head and the three fatty acid tails. If you only had sugars or only had fatty acid chains, you wouldn’t get one of these triglycerides and it couldn’t be stored in your fat cells.
So how are these formed?
When we eat carbohydrates (bread, fruit, grains, beans, candy, etc) it’s all one thing to the body — sugar.
Some sugars may be broken down slower and some faster, but they all end up as something called glucose — blood sugar.
Now, when sugar hits the blood stream it needs to be cleared out for two main reasons: first, so it can be used as energy, and second, because higher levels of sugar are harmful to the walls of our blood vessels and can cause injury to them.
So when sugar comes in our body releases a hormone (a messenger chemical that instructs the cells on what to do) called Insulin. Insulin’s job is to clear the sugar out of the blood stream.
And Insulin does this in one of three main ways and in this basic order:
First, it tells the cells throughout your body to take in the sugar so it can be mixed with oxygen to create something called ATP (the actual energy form the cells use).
Second, if the cells are full, then Insulin tells the muscle and liver to take in the extra sugar and turn it into chains of sugar to be stored for fast use in the future. These chains of sugar are called glycogenor glycogen stores.
And third, if there is still too much sugar for the above, because both the cells and the glycogen stores are full, then insulin directs the body to connect up the sugar with fatty acid chains and convert it all into triglycerides — body fat, which is then stored in your fat cells.
Now, this fat is a sort of energy savings account.
You see, later on, if the cells are out of glucose (sugar), and there is no more sugar in the blood to put into the cells, then the body releases a different hormone called Glucagon.
Glucagon goes to the muscles and liver and breaks the glycogen (stored chains of sugar) back into individual sugars for use.
This then causes the release of Insulin again which lets this newly released sugar into the cells.
Then later, if these cells are again empty, and all the glycogen stores are depleted, the Glucagon is release again and tells the body to release an enzyme called Lipase. (Enzymes are chemicals in the body that cause chemical reactions.)
Now the Lipase goes to the fat cells (energy savings account) and starts breaking down the triglycerides (body fat).
It does this by releasing the sugar head (glucose), but also by converting the fatty acid chains into something called ketones. It’s a bit more complicated than that, but ketones are basically another energy source the cells can use in place of glucose.
Now, while all of this is happening all of the time to some degree, it all happens mainly in that basic order.
While insulin is in your blood stream, the hormone glucagon, and the fat-burning enzyme lipase, are suppressed, and fat burning is very minimal.
So from a practical view we see that if we consume more carbs than our bodies can put into the cells or store as glycogen, then we build fat. And if we have extra fat we want to get rid of, we need consume less carbs than our body needs to operate so that it’s willing to tap into the fat stores for energy instead.
Also important: while insulin is in your blood stream (which it will be until the sugar is cleared out), the hormone glucagon, and the fat-burning enzyme lipase, are suppressed, and fat burning is very minimal. Obviously, because why use your savings account (body fat) when you’ve got new energy coming in already?
But this also means that if we’re constantly eating high sugar foods throughout the day then we have higher Insulin levels in our blood stream throughout the day and no amount of exercise will get rid of our fat because… the hormone Glucagon and the enzyme Lipase are suppressed, so fat burning can’t occur.
This is why people do intermittent fasting or fasted workouts. They eat dinner at around 6pm and then don’t eat breakfast the next morning. At this point the sugar has been out of the blood stream for many hours and, if a workout is done, the body will quickly go through its glycogen stores and then tap into the fat stores.
Then, if the person doesn’t eat again until lunch time you have several hours where glucagon and lipase are active to break down fat for energy.
Unfortunately, you also have protein breakdown during this time which can lead to muscle loss. (But don’t worry, PerfectAmino prevents that muscle loss without breaking the fast.)
So to recap: While sugar is in the blood stream we have the potential of fat creation and the prevention of fat-burning. And when sugar is out of the blood stream for many hours we have the potential of fat being utilized for energy, and so, fat loss.
But this is very two dimensional.
Why can't some people lose fat even if they cut out sugars?
Whatkind of sugar does this?
And what about Insulin resistance and Cortisol and…?
Yes, we need more…

If you’ve ever had a shock and felt the adrenaline surge in your body then you’ve felt cortisol. It’s a wake-you-up, get-you–ready-for-action hormone.
It really is. It hits its lowest point around midnight, so you can go to sleep, and then peaks again about an hour after you’ve gotten up in the morning, getting you to wake up and get ready for the day.
It’s nick-named the “stress hormone” because it’s released in moments of stress. So in a dangerous situation, or if you get scared suddenly, you’ll feel it.
But… when we have too-high levels of cortisol for too long, it can make us feel stressed… even if we have no reason to be.
