I’m about to wade into probably the most heated debates on the earth of health with you.

Does “energy in, energy out” work? Cue two teams of individuals yelling at one another on-line.
Group 1: “It’s easy! Simply eat much less energy than you burn!” Group 2: “It’s not concerning the energy! That DOESN’T work!”
So what are we to make of that?!
Right here’s the factor:
Either side are kinda proper.
And likewise… they’re arguing previous one another in a approach that I believe is unhelpful for everybody.
Let’s break it down.
⚖️ Energy In vs. Energy Out: The Precept
From a scientific standpoint, we even have a mountain of evidence and research to help the precept of energy in vs energy out.
The legislation of thermodynamics nonetheless applies to human our bodies.
If we had been in a position to completely measure energy consumed and energy burned, modifications in weight would observe.
This half is dependable and repeatable!
However…
🧠 When Most Individuals Say “Counting Energy Didn’t Work for Me,” They’re Not Arguing the Precept
They’re saying:
- “Monitoring energy made me depressing.”
- “I used to be at all times hungry.”
- “I hit a wall I couldn’t push previous.”
- “I tracked completely and nothing modified.”
- “It was too exhausting to take care of.”
They’re saying the technique didn’t work for them.
Not the physics.
🔄 Technique ≠ Precept
That is the place so many individuals get tripped up.
Energy In / Energy Out = the precept
Monitoring energy = a technique
You possibly can have an effect on the energy in/energy out equation with out ever monitoring a single calorie.
You can too observe each chunk and nonetheless really feel caught—as a result of the behavioral facet is off:
- Starvation hormones
- Stress ranges
- Sleep high quality
- Setting and triggers
- Vitality to prep or transfer
It’s not nearly understanding the numbers.
It’s about constructing habits and methods that assist these numbers change.
✅ That’s Why We Say
Weight reduction isn’t magic. It’s math + habits change.
All energy DO matter. AND, there are many environmental, bodily, and psychological components that have an effect on how a lot we eat and the way a lot we transfer. I’ve at all times liked this infographic from Precision Vitamin exhibiting all of the hidden components that go into the energy in, energy out equation.


So what’s the “proper” technique?
It’s the one which helps you affect that equation… sustainably.
Some folks love monitoring. Others hate it.
Some folks do nice with portion management, or high-protein meals, or decreasing takeout.
None of that breaks the precept.
They’re simply totally different instruments for a similar job.
For one individual, monitoring energy (the tactic) might assist them be extra aware of their parts and meals selections all through the day. They begin to plan forward for meals, and this ends in a slight and sustainable caloric deficit for them. They don’t hit all the pieces completely, however over time, they begin to see progress. For one more individual, monitoring energy might fully backfire! It makes them really feel neurotic and obsessive over the numbers. It’s actually tough to do, and even in the perfect of situations, monitoring energy at house isn’t an actual science. After a number of weeks, they aren’t seeing progress and it makes the method really feel depressing and demoralizing, not empowering. Each of those conditions are regular and EXPECTED. We don’t all have the identical our bodies, the identical environments, or reside in the identical state of affairs!
Actually, when you notice this, it’s like taking the Crimson Capsule within the Matrix. You possibly can see the code in every single place, and apply this identical thought course of to ANY food regimen or technique on the market.


Keto. Paleo. Intermittent Fasting. For some folks, these strategies create the habits modifications that result in sustainable variations in energy in, energy out. For others, they don’t.
So when you’ve ever had a coworker say: “I misplaced a lot weight simply doing X! You must strive it!” And then you definitely DID strive it and it didn’t be just right for you – you’re not damaged, it simply wasn’t the appropriate technique for YOU at the moment.
💡 The Backside Line
Let’s cease debating whether or not the precept works.
As a substitute, let’s begin asking:
What’s the perfect technique for this particular person individual to place that precept into motion, with out burning out?
You don’t must depend each calorie.
You can depend energy if it helps.
And you’ll completely make progress by specializing in the habits and behaviors that have an effect on that equation in a sustainable approach.
We put collectively our own TDEE calculator – which helps you ballpark the day by day energy you want based mostly in your exercise ranges. Steve and I additionally put collectively a information on the 10 Nerd Fitness Nutrition levels – these are sensible expertise which can be targeted on behaviors at the beginning, for those who really feel overwhelmed and aren’t positive the place to start out. Each are nice instruments in your health journey!
And if you would like assist determining what technique suits your mind, your life, and your targets, I’m only a reply away.
