What is ProLon® and how can I benefit?

Available at our London Harley Street clinic, the ProLon® body wellness programme is a nutritionist-supervised diet and wellness plan, using the science behind the ProLon® fasting kits. 

If you're thinking about cosmetic surgery, for your safety we need to ensure your BMI is within a healthy range. To reduce your BMI and maintain your health in general, a Prolon® programme could work for you alongside an exercise routine. 

Or if you’re thinking about your skin and body wellness, Prolon® sets clients up to see improved skin vitality and digestive health.

What are the benefits of fasting?

Simply put, fasting is a weight loss method, that requires you to abstain from eating and sometimes drinking for a certain period. There are different types of fasting methods, including the 5:2 and 16/8, but all methods follow the same principle. Fasting has been linked to lots of potential health benefits, including:

  • Weight loss
  • Lower blood sugar levels
  • Reduced insulin resistance
  • Improved brain health
  • Improved blood pressure
  • Reduced oxidative stress and inflammation in the body

ProLon® works differently to a typical fasting diet, by enabling you to receive all the benefits that fasting offers, whilst still allowing you to eat a set amount of calories throughout the day, as it suits you.

ProLon® skin and body wellness programmes

We offer four ProLon® programmes at our London Harley Street clinic, designed to achieve overall skin and body wellness. Our expert nutritionist Donald Gordon, BSc (Hons) NS, MFHT, AHCP (Reg) will tailor your programme to your goals.

  • ProLon Platinum:

    Platinum Wellness and Longevity Programme is the ultimate ProLon® dietary and educational programme to improve and maintain long-term metabolic rate, significant weight loss and BMI reduction. It has the added benefits of cellular regeneration and rejuvenation for younger, healthier-looking skin.

  • ProLon Gold:

    The gold reset programme will ‘reset’ the body, meaning clients will see improved skin vitality, digestive health and noticeable differences in metabolic rates – a full body reset. This programme offers clients a reduction in weight, improved BMI and confidence in better skin.

  • ProLon Silver:

    The silver kick-start programme sets clients up to see improved skin vitality and digestive health. We'll also prescribe a healthy eating programme, so overall there will be some weight loss benefits too.

  • ProLon Bronze:

    Differing from the other programmes, the bronze introductory programme is a one-day programme, for clients looking to boost their general skin health and the results of their sk:n treatment. This programme is also for those who have tried every avenue to treat their unresponsive acne and would like to try a nutritional programme.

What sets ProLon apart from other fasting programmes?

Those who participate in the 5-day ProLon cycle can lose body weight and belly fat while maintaining muscle mass. They can also see reductions in blood pressure, cholesterol and stem cell production, which according to scientists, these results appear to be limited to the precise makeup of the ProLon plan, not seen in other periodic fasts. The majority of those on ProLon sustain their results after the 5-day cycle has ended.*

“I found it really helpful to work with Don as he was able to recommend Prolon to me and my Husband and offer advise and support on what to expect when fasting, check in on how the fasting was going how we were getting on and feeling etc, suggest helpful tips. I would recommend Prolon to friends and family to help them achieve their health and fitness goals.” - Jade, ProLon customer

The practice of fasting involves calorie restriction. Do not start a fast if:

  • If you have a diagnosis of or are on a prescription for diabetes (type 1 or type 2), cancer, or congestive heart failure, or you have a history of fainting, fast only with the approval and supervision of a healthcare practitioner.
  • If you have a fever, cough, diarrhoea, signs of an active infection, or are at risk for a repetitive infection.
  • You are underweight, pregnant, or breastfeeding.
  • If you have a known, diagnosed or suspected eating disorder.
  • You are under 18 years of age, or over the age of 70.
  • You have dietary restrictions.
  • You are underweight or do not want to lose weight - during the fasting period, an individual will naturally lose 2-5% of his/her body weight
