Intermittent Fasting PLUS
I prescribe intermittent fasting often to my patients as it has phenomenal benefits including improving your blood sugar control; to weight management; reversing medical conditions like type 2 diabetes, fatty liver, IBS and auto-immune illnesses.
It has amazing anti-inflammatory benefits as well as anti-ageing and rejuvenation effects and anti-cancer effects which makes fasting an amazing intervention which can help you from multiple directions.
It improves energy levels and optimises gut health as well as banishing brain fog and bringing mental clarity. I have seen tremendous patient transformations but, you have to do it the right way in order to achieve the results you are looking for.
I have designed this 90 day intermittent fasting PLUS programme to guide you to achieve an effective fast with relative ease and without the potential side effects many people experience when they start out with fasting. In this programme you will:
- Learn how fasting affects your metabolism;
- Discover that you have to eat correctly and nourish your body with the proper nutrition in order to achieve the benefits you want
I will teach you how to exercise correctly when you are fasting and I will guide you with the other lifestyle aspects that are super important such as sleep, stress management and mindset in order for you to apply fasting in the correct and optimal way.
Have you tried Intermittent Fasting only to be frustrated as you are not seeing the results you were looking for? Instead you feel tired, miserable, you are grumpy all the time and you’re starving. It might be that you are making one of the common fasting mistakes.
If you have never tried fasting despite wanting to because you are nervous to tackle it on your own or concerned about the side effects, I will guide you on this journey and teach you how to gradually increase your fasting window to achieve a 24-hour fast within 6-8 weeks without experiencing negative effects.
If you are already quite comfortable with fasting, I will help you maximise the benefits through mindful structuring of your pre- and post-fast meals; optimal nutrition; sleep science; positive psychology and exercise principles and programmes designed to complement fasting.
You can’t reap the benefits by not skipping breakfast every day or just skipping meals and eating whatever you want the rest of the time. Don’t make the common fasting mistakes such as:
- Not nourishing your body correctly during your feeding window
- Not breaking your fast appropriately
- Not hydrating well
- Not exercising according to the principles of intermittent fasting
- and if you are a woman, not applying fasting in collaboration with your normal hormone balance.
Fasting is a lifestyle intervention which means most people, once they start fasting, they see the benefits they see how it affects their metabolism and they continue with fasting into the long term so that it becomes part of their normal lifestyle routine and so that they continue to enjoy the powerful metabolic effects for the rest of their lives.
If you are keen to try intermittent fasting in a scientific and evidence based way, sign up for the 90 day intermittent fasting programme today.

An additional benefit of signing up for the PLUS programme is how I break the Udemy content down into digestible portions allowing you to absorb it and put it into action.

Intermittent fasting is a powerful lifestyle intervention to achieve these goals but only if you do it in a practical, strategic and correct way.

ABOUT Dr. KAREN
Dr Karen Hartzenberg Medical Doctor | Lifestyle Medicine Specialist | Aesthetic Medicine Practitioner
Dr Karen Hartzenberg is a South African-born medical doctor and lifestyle medicine specialist based in Mauritius, where she has been in full-time clinical practice at Health Centre Labourdonnais, Mapou, since 2018.
She holds an MBChB from the University of Cape Town, a Master of Clinical Practice (Lifestyle Medicine) from Southern Cross University, and a Diploma of Aesthetic Medicine from the American Academy of Aesthetic and Anti-Ageing Medicine — one of a relatively small number of clinicians globally to hold a postgraduate qualification in lifestyle medicine.
With more than ten years in private general practice, Dr Hartzenberg specialises in the prevention and reversal of lifestyle-related chronic disease. Her clinical work spans metabolic health, weight management, diabetes prevention, food addiction and substance avoidance, sleep, and stress — always with an emphasis on sustainable, whole-person care rather than symptom management. She works with patients to build lasting habits through incremental, meaningful change, with the goal of reducing unnecessary reliance on medication wherever possible.
Nutrition and physical fitness sit at the heart of her practice and her philosophy. Dr Hartzenberg has a deep clinical interest in evidence-based nutrition — including low-carbohydrate, ketogenic, and Mediterranean dietary approaches — and in the role of regular movement as medicine.
She is a licensed Zumba instructor and teaches group fitness classes three times a week, and she brings the same enthusiasm for joyful, sustainable movement into her patient consultations.
Her commitment to lifestyle medicine is both professional and personal. Dr Hartzenberg reversed her own obesity, hypertension, pre-diabetes, hypothyroidism, and PCOS through the very principles she now teaches — and she brings that lived experience into her clinical work and public health communication, making her a compelling and credible voice on the real-world challenges of behaviour change.
In addition to her lifestyle medicine practice, Dr Hartzenberg offers non-invasive aesthetic medicine procedures focused on skin quality and rejuvenation.
She is the founder of Lifestyle Doc (lifestyledoc.co.za), where she publishes evidence-based content on nutrition, metabolic health, fasting, and preventive medicine, and develops online courses and programmes for patients and the public.
