Water retention is swelling in some part of the body, usually the feet and ankles, caused by large accumulations of fluid in the spaces between the body’s cells or in the blood vessels.

But it’s a symptom of something, not a condition in its own right.

And, while it can be caused by specific physical conditions of the kidneys, heart or circulatory system, most cases are actually due to lifestyles or diet, and they’re pretty easy to fix.

But there are many things that can cause this, so let’s jump in and see how this all works so you know what to do to help you.

In the last article we covered how many companies selling natural sweeteners such as stevia and monk fruit, knowingly or unknowingly cut their product with artificial sweeteners by 60% or as much as 100%.

They can do this because the only way to tell for sure is to do very extensive chemical testing.

Yet these artificial sweeteners can pose real health risks, from heart trouble to gut trouble.

And they're in about 99% of non-sugar sweetened products today.

But if it takes thorough chemical analytical testing to be absolutely sure it's natural, and you probably don't have access to that, what can you do to know what's real or not?

Well, there are a few ways.

We recently upgraded the sweeteners in our PerfectAmino Powder and PerfectAmino Electrolytes.

And in doing so we found out something quite disturbing.

We already knew some sweeteners labeled “Pure” or “All Natural” were often cut with artificial sweeteners to a degree, and we have always had to watch this.

But what we found out when researching natural sweeteners for our new formulation, and the amount of them that actually aren’t what they say they are, was surprising and somewhat scary.

It turns out, about 99% of so-called natural sweeteners actually contain artificial sweeteners in amounts as much as 60%, 80%… or even 100%.

And we want to make sure you know about this, why it matters, and what to look out for.

The body is a complex contraption, full of very exact systems, and a thousand different factors influencing its overall health and performance in one way or another.

But how do we separate out the important factors that allow us to measure our overall health and spot potential health troubles before they become a real situation?

There is something called Heart Rate Variability, or HRV, and it is a literal measuring stick for our health that we can use to monitor ourselves.

Whether we're into extreme sports and maximum physical performance, or trying to achieve optimal health for a long life, learning what HRV is, and how to use it, puts our health and performance in our hands.

This helps us spot trouble when it’s still a ways away, so we can handle it before it gets out of hand.

High stress levels are a leading problem in society today, with over half of Americans reporting they feel moderately to significantly stressed during the day.

This leads to depression and anxiety, as well as high tempers, and makes life much less enjoyable.

But it goes beyond that, because our mental stress levels affect our physical health.

Mental stress raises our cortisol levels, which in turn throws other hormones out of balance, lowers our ability to get deep, restorative sleep, causes weight gain, slows or prevents muscle building, and lowers our energy levels.

Stress also reduces our ability to recover from exercise and injury and lowers our overall health.

But while mental stress raises physical stress levels, this is not one-sided. Physical stress levels can raise and magnify mental and emotional stress levels.

In fact, our physical and mental stress levels work in tandem, each raising or lowering the other.

So what causes us to be stressed and how do we lower our overall stress levels?

How do we achieve a more even-keeled mood, more able to calmly face the challenges life presents?

How do we become the most alert and competent we can be mentally, while at the same time being able to relax when we need or want to, or when it's time to sleep?

And how do we raise our energy levels, improve hormonal balance, and increase our overall health?

Welcome to the Stress Series and 3 week challenge.

We already covered what PerfectAmino is actually doing in our bodies when we take it.

But I want to cover very specifically how it has a near zero caloric impact on our body, because this is important.

When we work out and take 20 or 30 grams of whey or pea protein, or collagen powder, we think our bodies are getting 20-30 grams of protein or collagen, and that's not true.

Protein and collagen aren't used by our bodies in the forms they arrive in. Instead, they're broken down into their building blocks -- the amino acids.

We’ve upgraded PerfectAmino by adding nucleotides and nucleosides — the building blocks of nucleic acids: our DNA and RNA.

But we want to make sure you fully understand why we did this and how this works.

Because it was for a very exact reason. And it is very much an upgrade.

We know that the building blocks of protein and collagen are the essential amino acids.

Having all of the essential amino acids, and having each of them in the correct overall ratio, is necessary for complete protein synthesis, as well as protein synthesis without the caloric impact.

However, there is another aspect to this.

While these essential amino acids are the material used to synthesize new protein, the actual building blocks of protein and collagen, if we want perfect protein synthesis then we need to look at the process of synthesizing protein itself: how they are being made.

Because if the process is at all faulty, then even if we have the correct amino acids and correct amounts, we won't necessarily get correctly made proteins.

In fact, we can even have stopped creation of specific proteins. And that can affect us in any number of ways.

Well done on completing the 30 Day Lean Body/Lean Bulk Challenge!

While you may feel and look different on the outside... on the inside things are even more different.

We’ve balanced hormones and repaired or replaced trillions of cells.

We’ve removed fat not only from our fat cells, but from our organs such as our liver and kidney, where it can make them less efficient or prevent them from doing their job.

We’ve built lean muscle and, depending on where we started, changed our body shape.

We’ve improved digestion and the microbiome, the most important gatekeepers for our overall health.

We’ve improved our body’s energy levels, our endurance, and our body's ability to recover, burn body fat and build lean muscle.

And we've set ourselves up, if we maintain our current lifestyle, to stay lean and continue to add muscle.

And if we have some extra deserts and gain a couple of pounds... we're now much more physically and hormonally set up to lose that very fast, often within a couple of days.

In short… we’ve done a lot!

But what do we do now?

The body is a complex contraption full of very exact systems and a thousand different factors influencing its overall health and performance in one way or another.

We need to be able to separate out the important factors that allow us to measure our overall health, performance and recovery ability, and spot potential health troubles before they become a real situation.

And that’s where Heart Rate Variability comes in.

Heart Rate Variability, or HRV, is a literal measuring stick of our current health and how well our body is able to adapt and recover. And it’s something we can use to monitor ourselves.

Whether we're into extreme sports and maximum physical performance, or trying to achieve optimal health for a long life, learning what HRV is, and how to use it, puts our health and performance in our hands.

This helps us spot trouble when it’s still a ways away, so we can handle it before it gets out of hand.

When working out, blood flow is very important for both muscle building and fat loss.

It’s how the nutrients, water and oxygen needed for energy creation and muscle creation flow to our cells.

If our blood flow is lower, our cells do not get these nutrients or oxygen fast enough and our energy levels go down during high intensity workouts.

And it slows recovery.

Achieving healthy blood flow then is important for maximum results and maximum overall health.

We've spoken a lot about hormones on the Lean Body/Lean Bulk Program, but not how toxins affect these.

Testosterone levels have been dropping for decades and the largest lab testing company, Lab Corp, actually lowered that standard of what “acceptable” testosterone levels are.

At the same time, estrogen levels have risen sharply and thyroid has become a growing issue.

Hormonal imbalances are no longer just being deficient in one or another hormone.

There are exact chemicals in the environment, in our food, air, and water, which didn’t exist before.

These chemicals can do several things in the body:

They can block certain hormones from being created.

They can block them from being able to communicate their instructions to a cell or disrupt their normal actions.

Or they can impersonate them entirely, giving our cells the message a hormone normally would, but not when the brain says to.

And while this affects muscle-building and fat loss significantly, its effect goes far beyond.

In this article we cover what's happening and what you can do about it.

We're entering Week Four of the Lean Body/Lean Bulk Challenge, and I want to add in something that will improve our recovery ability, our performance, our overall energy levels and our metabolism. And it directly affects our overall health.

It’s called VO2 Max. V is for Volume, O2 is for Oxygen, and Max is for Maximum.

VO2 max is literally the maximum amount, or volume, of oxygen that your cells can utilize during intense exercise, before you burn out.

And raising this allows us to raise overall performance, energy, endurance recovery ability and overall health.

And it allows us to push more over time and achieve more.

So let’s dive in.
