Muscle, Metabolism & Lifelong Health: Why Muscle Matters at Every Age
Muscle, Metabolism & Lifelong Health: Why Muscle Matters at Every Age
When people think about muscle, they often think about:
- Strength
- Appearance
- Athletic performance
But muscle is far more than that.
Muscle is one of the largest and most metabolically active tissues in the body. It plays important roles in:
- Movement
- Physical function
- Balance and mobility
- Strength and performance
- Recovery
- Metabolic health
- Healthy ageing
- Overall wellbeing
Whether you're a teenager, busy parent, recreational athlete, or older adult, maintaining healthy muscle is one of the most important investments you can make for long-term health.
Why Muscle Matters Throughout Life
Muscle health isn't only important for athletes or older adults.
Strong, healthy muscle supports:
- Everyday movement
- Physical resilience
- Energy metabolism
- Active lifestyles
- Recovery from exercise
- Balance and stability
- Healthy body composition
- Mobility and independence later in life
Building muscle early and maintaining it throughout adulthood creates a foundation for lifelong health.

Is Muscle an Organ?
While skeletal muscle is classified as a tissue rather than a single organ, researchers increasingly recognise that skeletal muscle functions as a highly active system that communicates throughout the body.
Muscle helps:
- Generate movement
- Support posture
- Store energy
- Maintain physical function
- Support active lifestyles
Researchers continue to investigate how muscle communicates with other tissues through signalling molecules known as myokines, highlighting the broader role muscle plays in whole-body health.
Muscle and Metabolism
Muscle is one of the most metabolically active tissues in the body.
Because muscle requires energy to maintain itself, it contributes to overall energy expenditure and plays an important role in metabolic health.
Researchers continue to investigate relationships between:
- Muscle mass
- Energy metabolism
- Physical activity
- Glucose regulation
- Body composition
- Healthy ageing
Maintaining muscle is increasingly recognised as an important component of long-term health.
Muscle as a Glucose Sink
Skeletal muscle is one of the body's largest storage sites for glucose.
After eating, glucose is transported into muscle cells where it can be stored and used for energy. Researchers continue to investigate how maintaining healthy muscle mass and regular physical activity support normal glucose metabolism.
This is one reason why resistance training and physical activity are considered important components of healthy lifestyle patterns.

Muscle Matters at Every Age
Childhood and Adolescence
Muscle supports:
- Movement and coordination
- Participation in sport and play
- Bone development
- Healthy growth
- Physical confidence
Healthy movement habits established early in life can provide benefits that extend into adulthood.
Young Adults
In early adulthood, muscle contributes to:
- Strength
- Energy
- Performance
- Recovery
- Healthy body composition
Building muscle during these years creates reserves that may support long-term health.
Busy Adults
For many adults balancing work and family, muscle supports:
- Everyday function
- Physical resilience
- Active lifestyles
- Healthy metabolism
Maintaining muscle becomes increasingly important as daily demands increase.
Active Ageing
As we age, muscle helps support:
- Mobility
- Balance
- Strength
- Independence
- Quality of life
Healthy ageing is not simply about longevity—it is about remaining active and physically capable.
Muscle and Weight Management
Many people focus exclusively on weight loss.
However, body composition is often just as important as body weight.
Healthy nutrition and exercise strategies aim to:
- Support muscle maintenance
- Preserve strength
- Encourage physical activity
- Support metabolic health
- Promote overall wellbeing
Rather than focusing solely on losing weight, many experts encourage maintaining or building muscle while pursuing long-term health goals.

Muscle and Physical Function
Muscle supports nearly every movement we make.
From carrying children and groceries to climbing stairs, gardening and hiking, muscle contributes to:
- Daily function
- Balance
- Stability
- Mobility
- Physical independence
Strong muscles help us stay active and engaged throughout life.
Muscle and Healthy Ageing
Age-related muscle loss is known as sarcopenia.
Natural declines in muscle mass can occur gradually throughout adulthood and may accelerate later in life.
Potential consequences include:
- Reduced strength
- Reduced mobility
- Lower physical function
- Increased fall risk
- Loss of independence
This is why preserving muscle is one of the most important healthy ageing strategies.
Healthy ageing approaches often focus on:
- Resistance training
- Adequate protein intake
- Regular physical activity
- Recovery and sleep
- Nutrient-dense diets
Researchers consistently identify muscle health as one of the strongest predictors of healthy ageing and quality of life.
Healthy ageing is not simply about living longer—it is about maintaining mobility, strength and independence.

Why Protein Matters
Protein provides amino acids that contribute to the maintenance and growth of muscle.
Examples of protein-rich foods include:
- Fish
- Eggs
- Poultry
- Lean meats
- Dairy foods
- Legumes
- Soy foods
Adequate protein intake is important throughout every stage of life.

Complete Proteins and Functional Proteins
Not all proteins are identical.
Complete Proteins
Complete proteins contain all essential amino acids and include:
- Meat
- Fish
- Eggs
- Dairy
- Soy
These proteins are important for maintaining and building muscle.
Functional Proteins
Functional proteins provide unique amino acid profiles that may complement a balanced diet.
Examples include:
- Bone broth
- Collagen peptides
These foods naturally provide collagen-derived amino acids including:
- Glycine
- Proline
- Hydroxyproline
A balanced nutrition approach can include both complete proteins and collagen-rich foods.

Where Bone Broth Fits
Bone broth has become increasingly popular among:
- Active individuals
- Busy families
- Recreational athletes
- Healthy ageing communities
A serve of Broth & Co Bone Broth provides approximately 5 g of naturally occurring protein together with collagen-derived amino acids including:
- Glycine
- Glutamine
- Proline
Many people choose to include bone broth as part of broader nutrition routines focused on:
- Protein intake
- Recovery nutrition
- Active lifestyles
- Healthy ageing
- Whole-food eating patterns
Bone broth complements complete protein sources rather than replacing them.

Frequently Asked Questions
Why is muscle important at every age?
Muscle supports movement, metabolism, balance, physical function and overall wellbeing throughout life.
What is sarcopenia?
Sarcopenia refers to age-related loss of muscle mass and strength that occurs gradually during ageing.
Is muscle important for metabolism?
Yes. Muscle is one of the body's most metabolically active tissues and contributes to energy expenditure and metabolic health.
How much protein do I need?
Protein requirements vary depending on age, activity levels and health goals. Individual needs are best discussed with a qualified healthcare professional or Accredited Practising Dietitian.
Is bone broth a complete protein?
