5-Day Guided Longevity Fast

Ready to Reset Your Body, Boost Longevity, and Feel Like the Best Version of You?

Welcome to The 5-day Guided Longevity Fast—a fully supported, science-led fasting experience designed to deliver transformative results in just five days, all from the comfort and convenience of your own home. It's a virtual retreat that delivers important and impressive results. 

Developed using the science of Dr Valter Longo’s Fasting Mimicking Diet (FMD) and refined through Amanda’s 23 years of fasting and nutrition practice, the Longevity Fast gives your body the benefits of a traditional fast—without total food restriction.

You’ll follow a low-calorie, plant-based plan that triggers autophagy, the body’s natural cell-clearing and regeneration process, while keeping energy stable and hunger manageable.

All you need is a blender, a few basic ingredients, and a willingness to reset.

The 5-Day Fast – What Happens Each Day?

Amanda’s method is structured and science-led, but always practical and gentle. You’ll be guided through the key biological stages of renewal:

Day 1: The Switch Begins

Your blood sugar and insulin levels start to drop, signalling the body to shift from using carbs to tapping into fat stores for energy. This is the start of nutrient sensing—your body becomes more efficient at managing resources.

Day 2: Autophagy Activation

Old or damaged cells begin to break down and recycle—a cellular spring clean called autophagy. Your body increasingly turns to stored fat for fuel, kickstarting visible fat loss

Day 3: Deep Adaptation

You're now in full fat-burning mode. Behind the scenes, stem cells—your body’s internal repair crew—may start activating. This is where the real metabolic magic begins.

Day 4: Regenerative Mode

Inflammation reduces further, and many people feel a boost in energy and mental clarity. This phase supports deeper repair across tissues, hormones, and immune pathways.

Day 5: Gut healing, shape change and transition

Inner healing continues, including the regeneration of the gut lining—an effect linked with reduced intestinal permeability (“leaky gut”). You'll  notice visible changes in skin lustre and body composition. A carefully structured transition menu helps you reintroduce food gently while preserving the results of your fast.

Support before, during and after your Longevity Fast 

You'll be invited to join the Longevity Fasting group in our private community app 7-days before your fast begins, plenty of time to say (virtual) hellos and get yourself prepared. 

Live group sessions are run daily during the retreat at 1pm (GMT) weekdays, and 10am (GMT) weekends.  On-demand videos, chat support and recordings available throughout.  Note, additional 1:1 coaching sessions with Amanda are available during your fast, please request at time of booking. 

Plus, we help you build momentum after your longevity fast ends, with a complimentary follow-up to support your long-term health goals.

Places are strictly limited so please book your place early!

We know that plans sometimes change - we allow for one date changes per participant at no cost.
