Verifying with Data: Did Front-Loading, Which I Started with Skepticism, Actually Work?
The Meal Distribution Known as Front-Loading
A while ago, I switched my eating habits to "front-loading."
This is a method of shifting the focus of daily intake toward the morning and early afternoon.
I wrote about the background leading up to this and how my dialogue with generative AI triggered it in another article, so I will omit it here.
What I want to write about today is what happened next. Did this method, which I started with skepticism, actually have an effect?
And if it did, how did I verify it?
I didn't want to end it with "I feel like it was good"
When starting a new habit, it usually feels good at first.
However, if you leave it at that, you won't know if it's a real effect or just a mood or assumption.
I had previously experienced taking a detour due to assumptions, so this time I didn't want to end it with "I feel like it was good."
So, I decided to verify it from two angles.
One is data visible in numbers.
The other is self-dialogue, where I carefully put my feelings into words.
What the data answered: Lean body mass
The goal I was seeking from front-loading was clear.
It was to increase my "lean body mass = body weight excluding body fat."
This is because I believed it would be the foundation for my daily condition and a body that can work for the next 10 years, rather than just for appearance.
I had also just started strength training.
Therefore, the indicator to verify was also clear.
It is body composition data.
As I continued with front-loading and strength training, my lean body mass moved in the targeted direction according to the data.
Of course, this is just my personal record and does not prove the effectiveness of front-loading alone.
Even so, the fact that the numbers responded to the goals I set became a great support for me to keep going.
What my self-dialogue answered: I don't get sleepy in the morning or the afternoon
The other aspect is my sense of well-being.
Since switching to front-loading, my mind stays sharp in the morning, and I hardly notice that afternoon sleepiness after lunch anymore.
At this point, I posed a question to myself.
I asked, "Isn't that just thanks to the so-called beginner's bonus from when I first started strength training?"
In the beginning, it's easy for anyone to see results.
However, even now that the initial growth has leveled off, the feeling of not being swayed by sleepiness from morning to night remains unchanged.
At the very least, it cannot be explained solely by the beginner's bonus.
That is what I was able to confirm for myself.
Skepticism turned into my own personal proof
The numbers met my goals, and the feeling remained even after the beginner's bonus period.
With these two things combined, the front-loading I started with skepticism changed from "it probably works" to "it worked for me."
Just to be clear, this is not a proof of a universal solution for everyone.
It is merely one sample—me—and my data and my sensations have simply indicated as much.
Even so, for me, that was enough.
I looked for the evidence afterward
Only after I was able to verify it for myself did I finally start looking for the evidence of "why this works."
Shifting the focus of intake to the first half of the day reduces hunger, finishing meals earlier is linked to metabolic indicators, and smaller portion sizes lead to milder post-meal blood glucose fluctuations.
As I looked into it, I found several studies that explain my own experiences.
I have compiled these mechanisms and primary sources, including the caveat that individual differences are significant, into a guide on the meiseki OS website.
This is the repository for the "evidence" I found later.
Please feel free to use it as a reference.

The relationship between afternoon drowsiness and blood glucose is also covered in this guide.

Don't impose. Just reflect.
Looking back, what I did was simple.
I tried it, verified it with data and self-dialogue, and added the evidence later.
This order is exactly what I want to make the norm at meiseki OS.
Instead of handing out "correct answers" given from the outside, I want to place the meal distribution you recorded alongside your sleep and condition the next day, and quietly reflect on "what it is like for you."
Deciding what to change and how is entirely up to you until the end.
