16hrs For Life

Better metabolic health. A better way to live.

It starts with food. It extends to how you live.

Rooted in real food and practical intermittent fasting, 16hrs For Life has grown into a broader philosophy of metabolic health — with nutrition at its heart, supported by movement, sleep and stress awareness.

The modern challenge

Modern lifestyles have changed. Our biology has not.

Highly processed food is everywhere, eating patterns have become irregular, and many people find it hard to sustain changes on their own. These factors are associated with excess energy intake, unwanted weight gain and markers of poor metabolic health such as insulin resistance. Physical inactivity, poor sleep and chronic stress can also influence health and everyday eating habits.

Information alone rarely changes habits. Practical education, a clear structure and ongoing support can make a meaningful difference to whether change lasts.

Our beginnings

It started with a simple belief.

16hrs For Life began with a simple idea: changing when and what we eat can be a powerful starting point for improving metabolic health.

What began with intermittent fasting evolved into a broader understanding of the habits that influence our wellbeing. Today, the name represents more than a fasting window: a philosophy of sustainable change, grounded in real food, practical knowledge and healthier everyday habits.

The idea became experience. Experience became the Metabolic Comeback Method. Now, education, digital tools, human support and emerging clinical collaboration form a connected ecosystem.

Shaun Waso, founder of 16hrs For Life

Meet Shaun Waso

Founder of 16hrs For Life and creator of the Metabolic Comeback Method

With a background in industrial engineering, business leadership and systems design, Shaun Waso brings a practical, analytical approach to metabolic health.

His own experience with metabolic health challenges sparked a deeper interest in nutrition, insulin resistance and intermittent fasting — eventually leading him to establish 16hrs For Life.

What began as a focus on changing eating habits has evolved into the Metabolic Comeback Method, a structured program combining nutritional education, lifestyle change, coaching and digital support.

Today, Shaun is working to extend that approach into the healthcare environment through the developing Clinic Partner Program.

His philosophy is straightforward: food is the foundation, but lasting health is about how we live.

Our philosophy · Four connected elements

It starts with food. It extends to how you live.

Food is the foundation of our approach to metabolic health. But how we move, sleep and manage stress also matters. These connected habits work together to support better health and lasting change.

01 · The foundation

Nutrition

Change your relationship with food. Build meals around nutrient-dense whole foods, understand carbohydrates and develop eating habits you can sustain.

  • Real, nutrient-dense food
  • Less highly processed food
  • Carbohydrate awareness
  • Fasting where suitable
  • Hunger and appetite cues
  • Sustainable eating habits

02

Movement

Strength & resilience

Regular walking, less sitting and appropriate strength activity help support muscle, physical function and everyday capacity.

03

Sleep

Rest & recovery

Consistent routines and sufficient, good-quality sleep support recovery, appetite regulation and everyday wellbeing.

04

Stress

Sustainable habits

Stress awareness, recovery routines and practical coping strategies support consistency under everyday pressures.

Food is the foundation. Lifestyle supports lasting change. These are educational principles, not specialist exercise, sleep or mental-health treatment. Fasting or significant dietary changes may require medical supervision, especially when taking glucose-lowering medication.

From philosophy to method

Experience became structure. Structure became a method.

16hrs For Life is the founding philosophy. The Metabolic Comeback Method puts that philosophy into practice: a structured 12-week program with nutritional change at its centre, supported by education, daily tracking and accountability.

Change the way you eat. Build habits that support the way you live.

Movement, sleep and stress awareness support the wider approach; they are not separate specialist services.
