Hunger Hormones
Why does your body send hunger signals even when you just ate?
Lesson 1 of the Wondering course Understanding Zepbound for Weight Loss
Your Body's Fuel Gauge
Hunger is not only about willpower.
Your body uses tiny chemical messengers called hormones to tell your brain when you need food and when you have had enough. Think of them as the fuel gauge in a car.
When the gauge works well, you notice the signal and stop eating.

- Hunger hormones
Two Natural Messengers
Your intestines release two hormones after you eat: GLP-1 and GIP.
They travel to the brain with one message: you are satisfied. They also tell the stomach to empty more slowly, so fullness lasts.
These are the natural signals Zepbound copies.
- You eat: Food arrives and the intestines respond.
- Hormones release: The intestines release GLP-1 and GIP.
- Brain signal: The hormones travel to the brain to signal that you are satisfied.
- Stomach slows: The stomach empties more slowly, so fullness lasts longer.
When The Signal Is Weak
For many people struggling with weight, these signals do not work effectively.
The body may eat enough calories, yet the fullness message stays too weak to notice. Hunger keeps talking.
That is biology, not a personal failing.
How Zepbound Steps In
Zepbound (tirzepatide) acts like those two natural hormones.
It targets the areas of the brain involved in hunger and cravings, making it easier to eat less and feel full longer.
In short, it turns up the volume on the body's own "I am full" message.

Check yourself
Hormones can act as chemical messengers that tell the brain when a person may be hungry or full.
- True
- False
Answer: True
This is true. Hormones are chemical messengers that help send hunger and fullness signals to the brain.
After eating, GLP-1 and GIP travel to the _____ to signal satisfaction and tell the _____ to empty more slowly.
Answer: After eating, GLP-1 and GIP travel to the brain to signal satisfaction and tell the stomach to empty more slowly.
The brain receives the satisfaction message, while the stomach empties more slowly so fullness lasts longer.
Which situation best shows a weak fullness signal?
- A person feels full and stops eating after a meal.
- A person remains hungry even after eating enough calories.
- A person becomes thirsty after exercising.
- A person smells food before eating.
Answer: A person remains hungry even after eating enough calories.
A weak fullness signal means the body may have received enough calories, but the brain does not strongly notice that the person is full. This is biology, not a personal failing.
