Nutrition Basics PLUS from Dr. Karen
I am simply delighted you are interested in purchasing my Nutrition Basics PLUS series. Over 90 days, in this series, we will journey through my Udemy Nutrition Basics 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 8 sections designed to help you understand the nutritional needs of your body better so you can be confident in making good food choices. Transform your health, control your weight, and enjoy delicious food.
You will:
- discover how your body uses carbohydrates, proteins, fats, vitamins and minerals.
- learn that carbohydrates are NOT essential nutrients and that alcohol is a FOOD GROUP for a number of reasons.
- discover that drinking 8 glasses of water a day might not be necessary (and you will learn that there's a better way to gauge your level of hydration).
- understand why counting calories is a waste of time and mental energy.
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 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 optimising nutrition helps you with real-world examples.
About Dr. Karen
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.
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.
Is this programme for you?
Are you tired of conflicting nutrition advice? One week carbohydrates are the enemy, the next it's fat, and every headline seems to contradict the last. I will help you cut through the noise by teaching you how your body actually uses carbohydrates, proteins, fats, vitamins and minerals, so you can make confident food choices based on understanding rather than trends.
Have you counted calories, followed the rules, and still not seen lasting results? You are not alone, and it is not a lack of willpower. I will show you why counting calories often wastes precious time and mental energy, and what to focus on instead to support your metabolism, manage your weight and enjoy your food again.
Do you stand in the supermarket aisle unsure which products are genuinely healthy? Clever packaging and health claims can make shopping feel like a guessing game. I will guide you through meal planning, smart shopping and reading beyond the label, so you leave the store with confidence and put balanced, nourishing meals on the table for your whole family.
Do you already eat fairly well but want more energy and vitality? I will help you fine-tune your nutrition strategy with deeper insights into vitamins, minerals, hydration and hot topics like snacking. You may be surprised to discover that some well-known "healthy rules", such as drinking eight glasses of water a day, are not quite what they seem.
