Intermittent Fasting PLUS
I am simply delighted you are interesting in signing up to my Intermittent Fasting PLUS series. Over 90 days, in this series, we will journey through my Fasting for Vitality course (you can view the course here) and I will provide additional guidance and resources directly into your inbox to encourage and educate you.
The Udemy course is divided into sections designed to help you understand how fasting works at a metabolic level.
When you apply the principles of intermittent fasting you can:
- Reduce inflammation
- Gain control of your appetite and your weight
- Manage health conditions like diabetes, auto-immune illnesses and IBS
- Improve your energy levels
Optimize gut health - Enjoy mental clarity and banish brain fog
- Activate anti-cancer and anti-ageing pathways
In this course, I explain why simply skipping breakfast every day is NOT intermittent fasting, that you can’t unfortunately just skip meals and eat whatever you want the rest of the time if you want to reap the health benefits of fasting.
If you have never tried fasting before, you will learn how to gradually increase your fasting window to achieve a 24-hour fast within 6-8 weeks without experiencing negative effects.
And, if you are already quite comfortable with fasting, you will discover how to maximize the benefits through mindful structuring of your pre-and post-fast meals, optimal nutrition, exercise while fasting, sleep science, positive psychology and other lifestyle factors that can help you achieve your health goals.
You can work through the course at your own pace but as some of the sections are quite intense, each week I will share what content I think you should watch. Breaking it down into digestible portions will allow you to absorb it and put it into action.
Alongside the course, you will receive:
- downloadable resources such as recipes and guides.
- complementary videos digging deeper into how to overcome cravings and hunger, how to exercise while fasting vitamins, minerals, different diets, how to meal plan and shop as well as hot topics like snacking and calorie counting.
- case study videos sharing how intermittent fasting helps you with real-world examples.
- a webinar on the effect how you shop and what you bring home has on how you eat
- a webinar on the frequently asked questions about intermittent fasting.
Together, over the next 90 days, we will improve your health, vitality, energy and longevity through intermittent fasting!
Just a reminder while this is scheduled as a 90-day series, you can work at your own pace and will have lifetime access to all the content you receive. So, if you feel like you need more time to work through the material. don’t worry… You can re-visit any of the sessions and email content whenever you like.
I really love feedback and questions so feel free to email me at any time.
You receive all of this for the launch price of only $99. Are you ready? Let’s go!
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.
