Why I Stopped Intermittent Fasting and Started Eating Breakfast Again
I started intermittent fasting in 2024 and it worked. But after learning how protein per meal affects muscle, I changed my approach. Here’s why I started eating breakfast again.
Where I started
In August of 2024, I cleaned up how I was eating.
I cut out ultra-processed food. I focused on real food. And like a lot of people, I started with intermittent fasting.
I followed an 18–6 schedule.
It worked.
I lost weight. My bloodwork improved. It gave me structure when I needed it.
At that stage, the goal was simple: fix what was off.
What changed
Over time, my focus shifted.
Weight loss wasn’t the only goal anymore. I started thinking more about strength and what this would look like over the long term.
That’s when I came across research on protein.
What I had been doing was focusing on the total protein for the day. But the research suggests your body responds to protein one meal at a time.
To support Muscle protein synthesis, you need enough protein in a single meal to trigger that response.
For most people, that looks like:
- Around 30–40 grams of protein
- Enough of the amino acid Leucine to activate the signal
What happens when you crowd protein into a narrow window
This is the part I had to understand.
There appears to be a practical ceiling to how much of a muscle-building response you get from a single meal.
Once that signal is triggered, it does not keep increasing just because more protein is added to the same meal.
After that point, your body still uses the extra protein, but it does not continue to increase Muscle protein synthesis in a meaningful way.
There is also a temporary refractory period after eating, sometimes called the “muscle-full” effect. During that time, the muscle is less responsive to additional protein.
So when I was following an 18–6 schedule, I was doing two things:
- Reducing the number of times per day I could trigger that response
- Trying to make up for it by eating more protein at once
That combination does not appear to be the most effective way to support muscle over time.
Why this matters more with age
As we get older, the body becomes less responsive to protein. This is known as Anabolic resistance.
In practical terms:
- It takes more protein to trigger the response
- And it helps to trigger it more than once per day
That’s what made me reconsider how I was eating.
What I do now
I moved away from intermittent fasting.
Not because it didn’t work. It did.
But because I started optimizing for something different.
Now I try to give my body more than one real protein signal each day.
That usually looks like:
- A breakfast built around protein
- A dinner built the same way
- A simple protein snack in between
Most days, that snack is just cold sliced steak.
What my breakfast looks like now
This is not complicated.
Eggs and meat. Sometimes leftovers. Sometimes something fresh.
The goal is simple: make the meal count.
How this ties back to the farm
Eating this way depends on having real food available.
If you’re going to eat protein more than once a day, it needs to be something you trust and something you can keep on hand.
At Tyner Pond Farm, that’s what we focus on:
- Cattle raised on pasture and moved regularly
- Chickens rotated on grass
- No antibiotics in our beef or chicken
- A system built around soil and animal health
We’re not trying to engineer food.
We’re trying to produce food you can rely on.
What I’ve taken from it
Intermittent fasting helped me get started.
It helped me remove what didn’t belong in my diet.
But this next step is about something else.
It’s about making sure each meal actually does something.
Final thought
I don’t see this as changing direction.
I see it as continuing the same process.
Start by removing what doesn’t belong.
Then start asking what’s missing.
For me, what was missing was enough protein, often enough.
That’s why I started eating breakfast again.
FAQs
Why did you stop intermittent fasting?
I stopped because research suggests muscle protein synthesis is triggered by protein at each meal, not just total daily intake. Eating more often allows for multiple opportunities to support muscle.
Does intermittent fasting affect muscle?
It can. If protein intake is limited to one or two meals, it may reduce the number of times muscle protein synthesis is stimulated during the day.
How much protein should you eat per meal?
About 0.4 grams per kilogram of body weight per meal, or roughly 30–40 grams for many adults.
What is the leucine threshold?
It refers to consuming enough leucine (about 2.5–3 grams) in a meal to trigger muscle protein synthesis.
Is breakfast important for protein intake?
If you are trying to maintain or build muscle, having protein at breakfast can help provide an additional opportunity to stimulate muscle protein synthesis.
