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. Average weight loss is 6lbs, with improved energy, clarity, gut health, skin and overall long-term health.

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 delicious low-calorie, plant-based recipe 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.

"Amanda is Queen of the Detox Scene" - Sunday Times 

“The accountability with the other participants—and the amazing support—makes this fast SO much easier to do!”— Claire

"The longevity fast was a complete game changer for my health, which had not been great this year. The recipes were delicious and very filling and there was such a lot of fascinating information about what was happening to our bodies during the fast. I am feeling energised both mentally and physically which is totally down to the fast." — Jan

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 with educational resources, videos, and live calls. Here's what your body will experience:

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.

How the Longevity Fast works

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

You will have access to a recipe booklet full of delicious nutritious recipes that you'll use for life! The recipe book covers 3 optional prep days, 5 fasting-mimicking days and 3 transition days. The fasting days include a light menu of delicious smoothies, salads, soups and vegetable dishes.

Live group support sessions are run daily during the fast at 1pm weekdays, and 10am weekends.  On-demand videos, chat support and recordings available throughout. You will also have access to live movement sessions, and educational and mindset resources.

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 call to support your long-term health goals.

Places are strictly limited so please book early!

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