Healthy Cooking and Yoga Weekend Retreat

"I have had the most amazing life enhancing (if not changing) week of my life at Jane Parker's retreat."

Come and join us at our stunning Healthy Cooking and Yoga Retreat in Cornwall.


Jane has designed a liver detoxification program inspired by her nutritional training and many years as a professional cook. Jane's simple approach to food promotes natural and seasonal ingredients, and is backed up by scientific evidence of the power of food to heal the body.


Jane's detox includes abundant vegetables, fruit, pulses, nuts, seeds, herbs and spices, and will give your body all the essential nutrients to enhance detoxification pathways and start the process of removing toxins.


Our Healthy Cooking and Yoga Retreat focuses on cookery, learning the skills to cook delicious food, and making the connection between food and health. The program also combines daily yoga practice, meditation, sauna, massage, nutritional advice, and amazing food, broths and juices whilst allowing participants time to relax and enjoy the quiet, natural surroundings of the Cornish countryside and woodland for a truly holistic experience.

Why do we need to detox?

It is becoming more and more apparent that our modern way of living is not suiting us with higher incidences of diseases such as heart disease, diabetes and Alzheimer's. Why is this happening? It is for many reasons, but a fundamental one is our modern diet. We are eating a diet that no longer resembles the one we were eating just a short time ago, and today we are burdening our systems with GMOs, chemicals, unhealthy fats, sugar, antibiotics, and the list goes on. It just makes sense to strip out some of the modern foods that are harming us and to eat more naturally.

Removing all the refined and modern foods and stripping it back to a completely natural diet of abundant fruit, vegetables, nuts and seeds is a great place to start to find the diet that uniquely best suits you and enables you to achieve optimum health.

Three key considerations:

Firstly, we are all different... there is no singular correct diet, and diversity is important, as is finding out what works for us as individuals at whatever stage of life we are at.


Secondly, fresh foods with an emphasis on seasonal foods providing the highest nutrient content and free from preservatives.


And, thirdly, whole foods, for roughage and fibre, whilst avoiding processed foods introduced since the agricultural revolution.

The ideal diet:

  • Is High in Nutrients

  • Is High in Fibre

  • Supports Gut Health

  • Is Anti-inflammatory

Our detox

As well as being a qualified Naturopathic nutritionist, Jane is an award-winning chef. Jane will be focusing the menus for the weekend on gently detoxifying meals. These will include organic smoothies, vibrant salads, colourful vegetables, juices, gut healing broths, wild fish, some nuts and seeds and lots of fresh herbs. Herbal teas and filtered water will be on tap! The retreat is alcohol and caffeine-free.

This is designed to be a detoxifying program and so is stripped right back to exclude the foods that may cause gastrointestinal problems, which Jane will discuss during your time with us. You will learn what to eat to support detoxification and will go home with detailed instructions and recipes to give you inspiration to make healthy changes to your diet and lifestyle.

This food will be packed with nutrients to support your Yoga practice, make you feel energised and inspire you to make long-standing changes to your diet and consequently, your health.

Jane's aim is to help you find the diet that best suits your unique physiology. After experiencing Jane's food and discussing your health with her in a nutritional consultation, you will go home armed with the tools needed to support you.

It's about more than just diet...

Jane and her team will ensure that you have a really relaxing break and fully unwind. Daily Yoga, massage and other therapies, sauna, evening meditation and connecting with nature in Costislost's surrounding wild garden and woods come together with luxurious accommodation in a truly peaceful setting. This is an opportunity to connect with yourself, have time to reflect, and perhaps even decide that it's time to make some changes in your life.

Why choose Cornwall

Ancient name for Cornwall..Belerion or "the shining land"

Jane and her partner Nick have created a homely yet stylish retreat in Cornwall amongst some of the most beautiful ancient rugged landscape in the country. Immerse yourself in the nature and stillness and connect with yourself on one of our retreats.

Cornwall is a unique and magical place. Costislost itself lies in a gentle dip down and long track surrounded by woodland and nature, the perfect place to soak up the silence, gaze at the stars and find peace away from it all.

Do your practice and all is coming

                                                           Sri K. Pattabhi Jois – Mysore Ashtanga Guru


We are so fortunate to have experienced Ashtanga teachers for our Yoga retreats, authorised by the renowned Sri K. Pattabhi Jois Ashtanga Yoga Institute. Ashtanga is a system of Yoga transmitted to the modern world by Sri K. Pattabhi Jois (1915-2009). This method of Yoga involves synchronizing the breath with a progressive series of postures—a process producing intense internal heat and a profuse, purifying sweat that detoxifies muscles and organs. The result is improved circulation, a light and strong body, and a calm mind.

There will be a morning Ashtanga session and in the afternoon a restorative Hatha Yoga session. Our experienced teachers will guide you, whether you are a beginner or have many years of experience already. Our retreats are purposefully for small groups of people so that we have more time to spend assisting you with your Yoga practice. Our Yoga space is wonderfully peaceful, the perfect place for authentic yogic practice and an opportunity to rest and restore in a beautiful location.
