CARB WEEK — DAY 1
FUEL WITH A PURPOSE
CARBS DON'T MAKE YOU FAT — SO WHAT DO THEY ACTUALLY DO?
Good morning, everybody. Welcome to Carb Week.
Last week, we spent five days talking about protein. We talked about why protein matters, how much you need, metabolism, protein quality, bioavailability, and then we brought everything together.
This week, we're moving to probably one of the most misunderstood nutrients in fitness:
Carbohydrates.
And I want to start Carb Week with a statement that's probably going to make some people stop scrolling:
Carbs don't make you fat.
Now, before somebody takes that sentence and runs with it, I'm also not saying:
Eat unlimited carbohydrates and nothing will happen.
That's not what I'm saying.
I'm saying carbohydrates themselves are not automatically body fat.
Your body actually has a reason for carbohydrates.
And once you understand that reason, you can stop being afraid of carbs and start learning how to use them with a purpose.
That's what this entire week is about.
SO WHAT IS A CARBOHYDRATE?
Let's make this really simple.
Carbohydrates are one of our three major macronutrients.
We have:
Protein.
Carbohydrates.
Fat.
Last week I gave you a really simple way to think about these.
Protein = BUILD.
Carbohydrates = FUEL.
Fat = SUPPORT.
Now, obviously, human metabolism is more complicated than those three words.
But if you're just beginning to understand nutrition, that's a great place to start.
Today we're talking about the fuel.
WHAT HAPPENS WHEN I EAT CARBS?
Let's say I eat some oatmeal.
Or rice.
A sweet potato.
A banana.
Fruit.
Those foods contain carbohydrates.
During digestion, many of those carbohydrates are broken down into simple sugars, especially glucose.
Glucose enters the bloodstream.
Now my body has decisions to make about that glucose.
And THIS is where I want you to start understanding your body differently.
Glucose can be used to help provide energy right now.
Or some of it can be stored for later.
And one important storage form is called:
GLYCOGEN.
That's one of the words I want everybody to remember today.
WHAT IS GLYCOGEN?
Think about glycogen as stored carbohydrate fuel.
Your body stores glycogen primarily in two important places:
Your muscles.
And:
Your liver.
Your liver glycogen helps maintain blood glucose between meals and during periods without food.
Your muscle glycogen is particularly important because your muscles can use it to help fuel muscular work.
So when I'm training...
Lifting weights...
Doing harder cardio...
Running...
Playing sports...
My body has a reason to have carbohydrate available.
That's why I don't look at carbohydrates and automatically think:
FAT.
I think:
FUEL.
THINK ABOUT YOUR MUSCLES LIKE FUEL TANKS
Here's a simple way to visualize it.
Imagine your muscles have fuel tanks.
You train.
You use some of that stored fuel.
Then you eat carbohydrates.
Now you can replenish some of what you've used.
So one of the questions I learned to ask through bodybuilding wasn't simply:
“Can I eat carbohydrates?”
It became:
“How much fuel does my body actually need?”
That's a completely different conversation.
THIS IS WHERE BODYBUILDING CHANGED MY THINKING
Competing taught me something very important.
Carbohydrates weren't automatically my enemy when I was trying to get lean.
In fact, I could still eat carbohydrates while getting extremely lean.
What changed was the strategy.
How much was I eating?
When was I eating it?
What was my training demand?
What was happening to my body composition?
Was I getting leaner?
Was I maintaining muscle?
How was I performing?
How was I recovering?
That's when food stopped simply being:
GOOD FOOD versus BAD FOOD.
And started becoming:
WHAT JOB DOES THIS FOOD NEED TO DO?
That's a major TruBody principle.
HEALTHY EATING AND EATING FOR AN OUTCOME AREN'T EXACTLY THE SAME THING
This is something we're going to get deeper into later this week.
You can eat foods that are nutritious and still not have the right overall amounts for the outcome you're trying to create.
Oatmeal can be nutritious.
Sweet potatoes can be nutritious.
Brown rice can be nutritious.
Fruit can be nutritious.
But that doesn't mean I need unlimited amounts of them.
That's where strategy comes in.
Because my body doesn't only care whether something has a reputation for being healthy.
My body responds to:
How much I'm eating.
What I'm eating.
How active I am.
What I'm asking my body to do.
How much total energy I'm taking in.
And:
How consistently I'm doing all of it.
SO IF CARBS DON'T AUTOMATICALLY MAKE YOU FAT, WHAT DOES?
This is where we need to clean up the language.
Body-fat gain happens when, over time, the body is storing more energy than it is using.
Carbohydrates can absolutely contribute to excess energy intake.
So can dietary fat.
So can combinations of foods that make it very easy to consume a lot of calories.
So I'm not giving carbohydrates a free pass.
I'm putting them in their proper place.
Carbohydrates are a fuel source.
And fuel can be useful.
But the amount of fuel should make sense for the demand.
Think about your car.
Gasoline isn't bad because your tank is full.
But once the tank is full, continuing to pump gas doesn't make the car perform better.
The question is how much fuel you need.
And that brings us to a TruBody phrase you're going to hear throughout this week:
FUEL TO DEMAND.
If I'm asking more from my body, my fuel needs may change.
If I'm asking less from my body, my fuel needs may change.
That's where carbohydrate strategy begins.
AND THIS IS WHY I DON'T TEACH “JUST CUT THE CARBS”
Could reducing carbohydrates cause someone's scale weight to drop quickly?
Absolutely.
But there's something important you need to understand.
When you store glycogen, you also store water with it.
So when carbohydrate intake drops significantly, glycogen stores can decrease and some associated water is lost.
The scale goes down.
But:
Scale weight going down does not automatically mean the same amount of body fat disappeared.
That's a BIG distinction.
At TruBody, I'm interested in:
What happened to your body fat?
What happened to your lean mass?
What happened to your strength?
What happened to your waist?
What happened to your energy?
What happened to your performance?
That's why I'm constantly telling people:
Don't just tell me how much weight you lost.
Tell me what you lost.
THE TRUBODY APPROACH
We don't need to be afraid of carbohydrates.
We need to understand them.
My approach is:
MEASURE.
FUEL.
TRAIN.
OBSERVE.
ADJUST.
Maybe somebody needs more carbohydrates.
Maybe somebody needs less.
Maybe we change the portion.
Maybe we change when they're eating them.
Maybe training days look different from lower-activity days.
Those are strategies we're going to unpack throughout this week.
But you can't manipulate carbohydrates intelligently until you first understand what carbohydrates are supposed to do.
And that's why Day 1 matters.
TODAY'S TAKEAWAY
If you remember nothing else from today, remember this:
CARBS ARE NOT AUTOMATICALLY FAT.
Carbohydrates are a nutrient your body can use for fuel.
They can become glucose.
Glucose can provide energy.
Carbohydrate can be stored as glycogen.
Glycogen can help fuel your muscles and support physical activity.
And whether you're losing or gaining body fat depends on a much bigger picture than simply:
“I ate carbs.”
So from now on, instead of immediately asking:
“Are carbs bad?”
I want you asking:
“What am I fueling?”
That's body literacy.
TOMORROW — WHERE DID YOUR CARBS GO?
Tomorrow we're taking today's conversation one step deeper.
You ate the carbohydrates.
They were digested.
Glucose became available.
Now where did it go?
Was it used?
Was it stored?
What's happening with your glycogen stores?
And how does all of that connect to body fat and fat loss?
That's where we're going next.
Because by the end of Carb Week, I don't want you simply saying:
“Coach T told me carbs aren't bad.”
I want you understanding carbohydrates well enough to start making intelligent decisions about them.
That's the difference.
Don't fear your fuel.
Learn how to use it.
Fuel with a purpose.
Learn. Train. Renew.
