Karin G. Reiter

Functional Medicine Nutritionist

With over 13 years of experience as a functional medicine nutritionist, Karin G. Reiter is a leading wellness expert known for her simple, practical, and ongoing solutions to improve health. 

At 18, Karin was diagnosed with her first autoimmune disease, Hashimoto’s. After the birth of her second child, she was then diagnosed with another autoimmune condition, celiac disease.

Her personal medical history, coupled with her positive mantra of “progress, not perfection”, has shaped her firm belief in using easy-to-apply methods that empower clients to take control of their health and lifestyle. Karin understands firsthand the transformative power everyday foods can have on our health, and how making small changes to our lifestyle can translate to a big difference in our well-being. She is deeply driven to help others wake up feeling radiant, energized, and thankful. 

Karin previously practiced in Sydney and Hong Kong before moving to Singapore in 2012. In addition to her work as a nutritionist, teacher, and speaker, she is also the mother to two active children, constantly cooking up new ideas to explore the healing powers of food.

Providing an inclusive environment for everyone, Karin is supportive every step of the way for those seeking to reboot their health through nutrients, food, and lifestyle choices. Her abundant energy radiates from her personal desire to help others avoid struggling through similar conditions she has faced in her past. Karin’s warmth empowers even the most timid wellness seeker to make transformational life changes from the foundation of a functional medicine nutrition approach.

“The most common misconceptions about diet and nutrition are that the same diet works for everyone and that the same diet works all the time. As a nutritionist, my job is to address these misconceptions.”

WHAT PARTICIPANTS ARE SAYING

Brain foods for hyperactive and inattentive kids

“I was looking for sound advice that was ethical but not alarmist on what my kids should be eating. I’m pleased to have received them from Karin. She gave me a huge reminder that I am 100% accountable and responsible for my children’s diet. She also changed my mindset on dealing with food refusal, which was a big aha moment! My three-year-old is starting to become quite argumentative, and I’ve started to say to him, ‘I’m sorry but I’m not arguing with you’ about his behavior. I will now be doing this with food too.”

“For the first time in my adult life I am comfortable in my body. I have found energy, confidence, vitality and happiness. I did not feel like I was dieting, I felt like I was eating delicious food all day long. Karin has a very holistic view of health and through this guide I learned the nutrition alone is not enough to be able to loose the weight and be healthy. Karin addresses nutrition, fitness, sleep, stress, mindfulness and so much more in this comprehensive yet friendly guide.”

Rachel

No guts, no glory!

"In 2016 I had attended a fermentation workshop In Singapore but it was such a waste of time, effort and money. Only notes 📝 were provided and everything else was up to you after the coursework. With Karin’s workshop it was a totally different experience, throughout her workshop she guided all the participants. She was always there for us along our journey she never let us fail. Loved the way she send us the tools we needed, guided us on where to source our products, with a open heart shared the details of ingredients she used on daily basis. I am really happy I made a choice to join her No guts, no glory! Class. Looking forward to keep learning from a great mentor like Karin 😘"

“As a busy executive I know the importance of staying healthy and focused at work. Tweaking my diet a little and stocking up on the right supplements has helped me a lot to support my immune system and I never miss work days anymore.”

Fabian

From fussy to foodie

“Thank you so much for this interesting session! It reminded me of all the important things I have to hear in mind when planning meals for my three little ones! I was so inspired that we prepared lentil curry, organic vegetable ratatouille, and brown rice together the day after the course. It was a big hit with my family and my two toddlers finished everything in 10 minutes — all by themselves! :-)”

"Karins approach to weight loss is balanced and sane. She does not cut out any major food groups and I can still enjoy a treat once a week. I am loving the "change your life seed bread" recipe and my husband is addicted to it too."

Suzi

The Rosy Cheeked Kids cookbook

"I have finally found a book that is made for busy mummies who still want to feed their children with healthy foods. The recipes are great not only for lunch boxes but for dinners too and I often find myself making double dinners and sending leftovers for lunch. Loved the ideas for birthday parties too."

Karen

From fussy to foodie

“A must for every parent and caretaker! Our children’s health is so important to us and it is fuelled by the food we give. I definitely learned what not to give my kids, and also some really exciting and inspiring ideas on what to feed them and how to get them involved. I love the strategies that Karin shared on handling picky eaters — they are not extreme and can be done step-by-step.”

"A very thorough, clear and aesthetic course. I wanted to bring natural probiotics into my family’s life, to replace probiotic pills. This fermentation course covered a large range of firm favourites such as sauerkraut and kombucha, as well as lesser used ideas such as lip-smacking beet kvass and very decadent goat milk kefir cream cheese spread with garlic and herbs. The kombucha I made from this course is far superior in taste and quality compared to expensive store bought versions. Thank you Karin, looking forward to more education and delicious recipes!"

Mona

"The course was really fun & well organised to the finest detail! I am very proud that I can make my own fermented food now & my whole family can benefit from it!"
