Did you know that whey protein powder spikes insulin levels, building as much body fat as sugar in many cases?
Insulin is the hormone responsible for shuttling sugar (glucose) to our cells.
But, when our cells can’t take any more sugar, then it attaches the glucose to fatty acids to create body fat. This is how body fat is created.
And, while insulin is present in the blood stream, fat loss cannot occur.
Now, normally sugar is what causes insulin to be released. But whey is unique among proteins in that it can cause as much or more insulin to be released than sugar can.
This is one of the biggest reasons that we build so much excess body fat along with muscle when bulking — because we’re also taking whey.
And it’s what causes our cuts to take so long.
Because, even when we cut calories and cut down on carbs, if we’re still taking high levels of whey, then to a large degree the whey is causing new fat creation.
And, at the same time, it’s also preventing fat loss.
All because of the high levels of insulin it stimulates.
But why is this and how does this work?
Let’s dive in.

Did you know that the official measurement of what is considered to be normal testosterone levels has been lowered?
It has. And this was done because the majority of men no longer fall into the earlier acceptable ranges.
Their testosterone levels are too low.
Why is this? What's happening? And why would they choose to lower the acceptable levels instead of addressing why they are lowering?
In this article we talk about what testosterone does in the body, largely from the view of its anti-aging effects, how lowering testosterone levels, not just in the elderly, speeds up our biological aging, and what is causing this.

If we want to build and keep lean muscle, or have a lean, toned, and shaped body without the excess body fat, there are key hormones we need to look at:
Cortisol is our stress hormone, released in times of physical or mental stress. It's necessary, but when it goes too high it acts to break down the muscle we do have, prevent or slow new muscle gain, and create and hold onto body fat.
Estrogen and Insulin also play a large role here.
On the other side we have Growth Hormone, Testosterone, and IGF, Hormones that act to repair muscle, bone, ligaments, etc, build lean muscle, burn excess body fat, and shape our body in both men and women.
But cortisol, estrogen, and insulin work on a sort of seesaw-reaction basis with growth hormone, testosterone, and IGF.
Raise one side and the other side lowers, and vice versa.
Increase cortisol and we decrease testosterone and growth hormone levels, causing fat gain, preventing muscle gain, and even breaking down the muscle we do have.
But raise testosterone and growth hormone and we lower cortisol, estrogen and insulin levels.
So while we've covered how to prevent cortisol, estrogen, and insulin from going too high in the above linked articles, in this article we cover how to increase levels of growth hormone, testosterone and IGF.
Let's dive in.

Cortisol is one of the most important hormones in our body. It’s been called the “stress” hormone because it’s released during moments of stress.
But it’s also the hormone that wakes us up in the morning, that starts the healing process in our body after any injury or workout, and that provides us with energy and mental focus when we’re “running low.”
But unfortunately, when cortisol levels go too high, it becomes something else.
It can cause muscle loss and prevent muscle gain, cause fat storage and prevent fat loss even when we’re exercising, cause low energy levels, cause us to feel stressed, cause poor sleep, and even slow or prevent healing and recovery.
If you have trouble with any of the above, it’s likely that higher than normal cortisol levels play a part.
But that’s when it’s too high. And, unfortunately, for many people in society today, it already is too high.
So let’s dive in and see what cortisol is, how it works and how we can balance our levels.

Did you know that when Estrogen levels rise too high, it can unbalance other hormones? And this significantly impacts body fat gain and loss?
We've covered several hormones now, from Insulin and Cortisol causing fat gain and preventing fat loss, to Growth Hormone and IGF, the hormones that come out while we sleep and which are largely responsible for fat loss.
We cover all of these because they all work together, each influencing the other, and if we want sustainable fat loss, we need to address each one.
But high Estrogen also plays a large role in all of this in both women and men, building excess body fat and lowering testosterone and growth hormone.
It also lowers thyroid, a hormone that regulates our metabolism, which in turn regulates body fat and energy levels.
And it lowers progesterone in women and men, a calming, fat-burning, testosterone-building hormone.
All of this leads to excess body fat, decreased muscle mass, worsened mood, higher stress levels, slower recoveries, and lower energy.
So let's see what's actually happening here, what causes this, and what we can do about it.

Today we want to walk you through a day in the life of someone using the PerfectAmino Performance Stack to build more lean muscle, increase energy and endurance, and improve recovery, all while slimming down.
Also, how it helps them to improve mental focus and clarity during the day and address stress levels, mood and the ability to relax in the evening and sleep deeply.
The PerfectAmino Stack includes: PerfectAmino, PerfectAmino Pre-Workout, PerfectAmino Creatine, PerfectAmino Electrolytes and PerfectAmino Strength & Recovery.
We're going to show when and how they're taken for best results.
And not just that, but what other actions do they take during the day?
What exercises do they do and when?
What foods do they eat and when? (And we include recipes.)
How do they get maximum sleep for recovery?
All of these points are important, so let's dive in.

If you’re over 40 years old, you’ve probably noticed that weight loss can become harder.
When we’re younger, in our teens, 20’s and 30’s, we can often (not always) get away with a lot. We can eat more carbs without gaining weight, and keep up our energy and strength levels high.
But after 40, things change. And this is a factor related to changes in our hormones as we age.

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 the standard of what “acceptable” testosterone levels are.
At the same time, estrogen levels have risen sharply in both women and men, and thyroid has become a growing issue.
All of this affects our ability to build lean muscle, lose body fat, and maintain heathy levels of lean muscle and fat. And it lowers our overall mood and health.
But while we've covered individual factors that can cause specific hormones to go too high or too low, there is another factor that affects them more broadly, and significantly.
There are exact chemicals in the environment (in our food, air, and water) which didn't exist before.
And 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 the cell's normal actions.
Or they can impersonate certain hormones 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 this.
It isn't a small issue. And every year its effects grow.
In this article we cover what's happening and what you can do about it.

In the last article we covered cortisol, a hormone which, among other things, acts to break down our muscle, breaking down the proteins in it into amino acids, which are then converted to energy sources such as sugar.
At the same time, it holds onto body fat and acts to raise body fat levels, while also preventing protein synthesis for new muscle growth.
But it also lowers key muscle building and fat loss hormones, so let’s cover what those are and how to maximize their production and use within the body for best results.
