What Is GLP-1? Understanding Appetite, Satiety & Nutrition

GLP-1 (Glucagon-Like Peptide-1) has become one of the most talked-about hormones in nutrition and metabolic health.

Interest in GLP-1 has grown rapidly because medications such as Ozempic®, Wegovy® and Mounjaro® work through pathways involving GLP-1 activity.

But what exactly is GLP-1?

And what role does nutrition play?

This guide explores the science behind GLP-1, appetite, satiety and balanced eating habits.

What Is GLP-1?

GLP-1 is a naturally occurring hormone released by specialised cells within the digestive system after eating.

Researchers continue to investigate its role in:

• Appetite and satiety

• Food intake

• Digestion

• Glucose metabolism

• Energy balance

GLP-1 forms part of a complex network of hormones involved in eating behaviour and nutritional regulation.

Where Is GLP-1 Produced?

GLP-1 is produced by specialised cells known as L-cells that are located primarily in the small intestine.

These cells release GLP-1 in response to food consumption.

Because GLP-1 is closely linked to food intake, researchers continue to investigate how dietary patterns influence appetite and meal satisfaction.

Appetite Is More Than Willpower

Many people think appetite is simply a matter of discipline.

In reality, appetite is influenced by multiple factors including:

• Hormones

• Sleep

• Stress

• Physical activity

• Meal composition

• Food quality

This is why sustainable nutrition strategies focus on building habits rather than relying on willpower alone.

The Role of Protein

Protein is one of the most important nutrients in the human diet.

Protein contributes to:

• Muscle maintenance

• Physical function

• Growth and development

• Overall nutritional adequacy

Protein-rich foods are also commonly included in nutrition strategies focused on meal satisfaction and dietary quality.

Examples include:

• Fish

• Eggs

• Poultry

• Lean meats

• Dairy foods

• Legumes

• Bone broth

Many nutrition professionals encourage including a protein source at each meal.

Where Bone Broth Fits

Bone broth provides a convenient source of protein together with collagen-derived amino acids.

A serve of Broth & Co Bone Broth provides approximately 5g of naturally occurring protein.

Bone broth naturally contains:

• Glycine

• Proline

• Hydroxyproline

• Glutamine

Many people choose to include bone broth as part of broader nutrition routines focused on dietary quality and protein intake.

What Actually Matters Most?

While interest in GLP-1 continues to grow, most nutrition professionals agree that long-term wellbeing is built on fundamentals:

• Adequate protein intake

• Fibre-rich foods

• Whole-food nutrition

• Physical activity

• Sleep

• Consistent habits

These foundations remain important regardless of whether someone is using medications or following food-first nutrition strategies.

Final Thoughts

GLP-1 has helped bring greater attention to the relationship between appetite, satiety and nutrition.

While researchers continue to investigate the science behind appetite regulation, the foundations of good nutrition remain remarkably consistent.

Focus on:

• Protein-rich foods

• Fibre-rich foods

• Dietary quality

• Physical activity

• Sustainable habits

because long-term wellbeing is built through consistency rather than quick fixes.
