Those are some big claims in that title.

And how could they be true when we have statements like:

“BCAAs stimulate the building of protein in muscle and possibly reduce muscle breakdown.”

“Valine is needed for your muscle fibers to fire, for tissue repair, and for the maintenance of proper nitrogen balance in the body.”

“Leucine stimulates muscle protein synthesis and may be the dominant fuel involved in anabolic (tissue building) reactions.”

Well, unfortunately, the claims in the title of this article are true.

They come from research studies done on BCAAs, while the above quoted statements come from marketers.

BCAAs, or Branched Chain Amino Acids, taken on their own regularly and over time, can have a significant effect on body fat creation, muscle gain reduction, kidney trouble, type 2 diabetes, metabolic syndrome, and obesity.

And it's becoming quite a problem. Just google "BCAAs side effects" or "BCAAs and Type 2 Diabetes" and you'll find much more than you wanted to.

But how can they say these things and how does this all work?

Let's dig in and see.

Welcome to Week One of the Lean Body/Lean Bulk Challenge!

In this article we cover what metrics to keep track of, dialing in your macros and workouts, and what to expect during week one.

In the first week of this challenge we have several things happening.

We’re trying to switch our diet so our bodies are getting what they need to build lean muscle without the excess calories or hormone-triggering foods that would cause fat gain.

With this comes restructuring our cells so they will use the foods we’re giving them properly and balancing or increasing hormone levels so our body will prioritize building lean muscle over body fat.

We’re addressing digestion, which is crucial to our overall health as well as building muscle, as we need our cells to receive all of the nutrients and vitamins we’re consuming.

You will be consuming a lot of whole food proteins, which your stomach is probably not used to receiving, and it will need extra help until it builds up enough stomach acid and enzymes of its own.

So make sure you’re taking your digestive enzymes with each meal during this.

We’ll also be working to dial in our exact macros.

And we may be experiencing some cravings.

On this protocol you will be lifting 5 days per week.

As this protocol is very specific to building lean muscle and toning, there will mainly be weight lifting.

There will also be something called Zone 2 Cardio, which will not cause muscle loss, but other than that there is no cardio during this challenge.

If you would like to take a walk, that’s fine. But adding in other forms of cardio could hamper your progress.

And it’s only 30 days.

Okay, let’s run through a few key points and then jump into the workouts.

On this protocol you will be lifting 5-6 days per week.

As this protocol is very specific to building lean muscle and toning, there will mainly be weight lifting.

There will also be something called Zone 2 Cardio, which will not cause muscle loss, but other than that there is no cardio during this challenge unless you have extra energy for Day 6.

But if you really want to build muscle, extra cardio is not recommended.

If you would like to take a walk, that’s fine. But adding in other forms of cardio could hamper your progress.

And it’s only 30 days.

Okay, let’s run through a few key points and then jump into the workouts.

Here we cover the specific supplements and macronutrient you will be consuming during this protocol and exactly how.

This protocol is meant for significantly increased lean muscle, so the macros may seem high to some. 

But it's also meant to be used with the Advanced Workout Regimen, so the macros will be used by our body.

There are three different macronutrient ranges to pick from depending on which Carb to Fat ratio you personally prefer, with notes on each.

There is also an exact way in which you will dial in your macros to ensure you are getting the correct amount for what your body needs.

Let's start.

Let's start.

When we look at Lean Bulking, building lean muscle without the excess body fat, we need to look back at what the original body builders did, the golden age body builders.

Because it was very different to what is done now.

And I'm not talking about the 70s or 80s when counting macros and Bulking & Cutting became popular.

We're going earlier.

To the time of Jack LaLanne and the other greats, before egg protein powders, whey powders, creatine, and BCAAs were first introduced.

Back then body builders ate very differently. But very effectively.

Ask anyone about bulking and cutting and they’ll bring up calories and macronutrients.

“You have to count your calories and macronutrients and make sure that you eat more than you need to build muscle (and body fat) and eat less than you need to burn fat.”

And that’s true… to a degree.

But there’s more to it. And if you just follow the above, you’ll more than likely miss your goals.

Yes, we need to measure the amount of calories to make sure we get enough energy, but not too much. And we need to make sure we get enough protein, fat and carbohydrates so we can build muscle or have energy to power us through the day.

But… which proteins, fats, and carbs? And how do they affect the hormones that will determine how they’re used?

Because it's our hormones that decide how these macronutrients will be used in our body.

Will the carbs and fats be turned into body fat? Or used as energy? Or will they become part of the structure of the body?

It’s our hormones that decide.

Will this protein be used to build muscle? Or will it be turned into sugar or body fat?

Hormones decide.

It’s not how much you eat that decides. It’s which exact food you eat and how that exact food affects your hormones.

Bulking and Cutting has been around for decades now.

We workout hard, we count our macros and eat and eat and eat, and build lots of muscle.

But at the same time that we’re building muscle, we also build body fat. And we build each at about the same rate, a pound of muscle for a pound of fat.

Then we do a cut, cutting back on our calories, and in some cases starving ourselves (which is never necessary).

And, of course, we do a lot of extra cardio — running, biking, sprints, etc. — all to lose that extra body fat we gained.

And hopefully we don’t lose too much of our muscle gains in the process.

Now, I have no problem if someone enjoys that. Many people do. But many others don’t.

And the thing is, this isn’t necessary.

At all.
