(This is Part 2 of a series that began with: Why All the Fuss About GLP-1 Drugs?)
If you’ve ever felt frustrated by hunger—
eating when you didn’t plan to,
feeling hungry soon after a meal,
or struggling with cravings—
you’re not alone.
And more importantly:
this is not a failure of willpower.
A Different Way to Understand Hunger
Hunger is not simply about how much you eat.
It is a signalling system.
It is regulated by a set of hormones that communicate between your gut, your brain, and your body.
These signals influence:
- when you feel hungry
- how full you feel after eating
- how your body stores or uses energy
When these signals are working well, hunger feels:
- steady
- predictable
- easier to respond to
When they are disrupted, hunger can feel:
- urgent
- confusing
- difficult to manage
The Four Key Signals
We can simplify this into four main players:
- Insulin — the storage signal
Insulin rises when we eat, especially refined carbohydrates.
Its role is to help store energy.
When insulin is frequently elevated—through constant snacking or highly processed foods—the body can become less efficient at accessing stored energy.
The result: hunger returns more quickly.
- Ghrelin — the hunger signal
Ghrelin is often called the “hunger hormone.”
It rises before meals and falls after eating.
But here’s something important:
ghrelin follows patterns.
If we eat at the same times each day, hunger begins to show up at those times.
This means hunger is not always an emergency—it is often a rhythm, showing up whether we are truly physically hungry, or not.
- Leptin — the fullness signal
Leptin tells the brain that we’ve had enough to eat.
But in many people, especially with diets high in ultra-processed foods (UPFs), this signal becomes less effective.
The body is producing the message…
but the brain is not receiving it clearly.
- GLP-1 — the “slow down” signal
This is the hormone we introduced in Part 1.
GLP-1 helps:
- create a sense of fullness or satiety
- slow digestion
- reduce the drive to keep eating
Medications like Ozempic work by amplifying this natural signal.
When Hunger Feels Out of Control
What many people experience today is not a lack of discipline.
It is a mismatch between modern habits and ancient physiology.
- food is more processed
- eating is more frequent
- sleep is often compromised
- stress is higher
All of this affects how these hormones function, as modern life creates confusion in the system.
Over time, the signals become less clear.
Hunger feels louder, more urgent
Fullness feels delayed
Cravings feel more persistent
A More Supportive Perspective
Instead of asking:
“Why can’t I control my eating?”
we might ask:
“What signals is my body sending—and how can I support them?”
This shifts the conversation from blame … to understanding.
What Begins to Help
When we start to support these hormonal signals:
- meals become more satisfying
- hunger becomes calmer
- eating feels more intentional
Not perfect.
But more steady.
More predictable.
More in tune with the body.
