Marie MacGregor

Registered Dietitian - Cape Town

Marie MacGregor is a registered dietitian based at the Sports Science Institute of South Africa (SSISA), with over 20 years of experience in the health, wellness, and fitness industry. She graduated from the University of Cape Town (UCT) with a BSc in Nutrition and Dietetics in 2004 and has built a career helping individuals translate nutrition science into real, sustainable results.

Marie works with a wide range of athletes, including cyclists, runners, triathletes, rowers, rugby, football, hockey, water polo, sailors, weightlifters, and boxers, to name a few, supporting them in optimising performance, recovery, and long-term health. She has guided athletes competing at the highest level, including at Olympic level. Her approach combines performance nutrition expertise with practical strategies that fit into demanding training schedules and real life.

Beyond sport, Marie consults one-on-one and within the wellness programmes at SSISA, supporting clients with conditions such as high cholesterol, heart disease, Irritable Bowel Syndrome (IBS), PCOS, diabetes, and other metabolic and gastrointestinal concerns, with a particular interest in the peri and post-menopause. Whether the goal is improved health markers, better energy, weight management, or enhanced athletic performance, her plans are tailored, realistic, and evidence-based.

Marie is an experienced presenter and educator. She has delivered numerous nutrition workshops and talks at SSISA, for corporate companies, NGOs, and the Department of Health. She has lectured at UCT, developed menus and event nutrition strategies for sports associations and academies, conducted nutritional analysis for food companies, contributed to media articles, and participated in radio interviews. She has also been involved in conceptualising online wellness programmes for the health insurance and fitness club industries.

The initial consultation lasts for roughly 60 minutes and is where we go through your goals, medical history, dietary history, training programme (if applicable), and any other relevant factors.

Once we have gathered all your information, we will go away and draw up your individualized eating plan and email it to you within 2-3 working days.
A follow-up appointment may be necessary. During a follow-up, we will assess the changes that you have made and your progress toward your goals and discuss any further changes that you may need.

The initial consultation (60 minutes + individualised eating plan) is R1650
