Oakville Nutritionist

Understand how your body consumes and responds to sugars, fats, caffeine, gluten, lactose and more. The point is NOT to cut everything out of your diet, rather, it’s to ensure you have a balanced approach and are getting all the nutrients you need as part of a basic wellness approach!

Member Testimonials

Having Jumanah as my family’s nutritionist has made a world of difference compared to any other nutrition program available before at One Health Clubs. She is charismatic, professional , very knowledgeable and takes her time to listen and to advise. There is no other word to describe than excellent.

I have truly enjoyed working with Jumanah at One Health.  She has worked hard to understand my lifestyle and my own health issues. She then developed a program built around a realistic set of goals and priorities. I have been very impressed with her knowledge, and commitment to follow-up. I truly appreciate how respectful she been of me, and how closely she has worked with my trainer at One Health as well. 


Jumanah is an excellent nutritionist. She is extremely knowledgeable and skilled. She provides nutritional advice while explaining the rationale for eating and combining certain foods as well as the importance of portion size. In addition, and perhaps most important for myself , she has provided strategies that assist with behaviour modification. This change in thinking and hence behaviour has helped me to deal with cravings, make healthy  choices in restaurants, and modify my eating habits in social situations.

Since I began the nutrition program with Jumanah roughly 5 weeks ago, I have lost 15 lbs and can feel a huge difference in my energy levels and general well being. I look forward to meeting Jumanah every week, as she is deeply knowledgeable about health, fitness and the true nutritional value of food. Instead of putting me on a strict diet, she has provided me with guidelines of what to cook and eat – all 15/20 min recipes which have been delicious and super easy to cook! I am truly grateful to her for putting up with my rebellious ways and always using facts to encourage me to change my habits. Nothing has worked this consistently well for me in almost two years – and it is INCREDIBLE to finally feel the pregnancy weight leave me once and for all!!!! None of it would be possible without Jumanah’s help every step of the way. Thank you SO SO much Jumanah!!!!!
