I absolutely LOVE working with On Ki Chan. We never talk about what not to eat, only what to eat more of. Her suggestions teach me so much about the science of what’s really going on in my body. We go with the path of least resistance, and it has paid off - I lost 10 lbs since working with her! All of the healthy changes feel so sustainable and healthy. I never feel like I have to be perfect or like I’m depriving myself. My friends and family hear about how much I love On Ki Chan all the time! So grateful to have found her.

Kimberly Chan Jacobson is extremely knowledgeable about nutrition. She gave me advice about my cholesterol level. She suggested changing (and adding specific vegetables and protein to) my diet. She suggested fish oil supplements. I listened, and by my next doctor's visit (post blood work), my numbers dropped. This is just one example of Kim's advice about improving my health. Mahalo Kim!

She goes above and beyond by reviewing blood work and offering personalized advice, supplements, and simple yet effective lifestyle changes (like drinking more water), all of which have led to incredible improvements in how I feel. Not only do I feel so much better physically, but I’ve also gained a deeper understanding of nutrition and its holistic impact on overall well-being. Kim is incredibly pleasant to work with, and her knowledge is vast—she takes the time to explain things in a way that makes sense.

Life-Changing Guidance from Kim Jacobson!I cannot recommend Kim Jacobson highly enough. I went to her feeling lost and frustrated with my health. I'd been dealing with high blood sugar and blood pressure for ages, and my doctor, while well-meaning, hadn't given me any actionable advice beyond general platitudes.Kim was a breath of fresh air! She took the time to truly listen to my concerns and provided me with incredibly valuable, personalized information that I had never heard before. She explained the "why" behind her recommendations, which made it so much easier to understand and implement them. I learned so much about managing my diabetes through diet and lifestyle.Honestly, the information Kim gave me was more comprehensive and helpful than anything I'd received from my own doctor. After following her advice, I felt a significant improvement in my energy levels and weight.The real testament to Kim's expertise came during my follow-up appointment with my doctor. He was absolutely stunned by my progress! He actually asked me what I had been doing differently, and when I told him about Kim, he was genuinely impressed.If you're looking for a dietician who will truly listen, provide you with actionable advice, and help you achieve real results, look no further than Kim Jacobson. She's changed my life!

Kim has been extremely knowledgeable and helpful every step along the way! She takes the time to understand her clients and all possible variables to make the best recommendations and decisions. It’s so refreshing to work with someone who has a wealth of knowledge and is personable and easy to talk to! I came with IBS and SIBO discomfort and so far she has given very useful guidance that has already started showing results. I would highly recommend her to anyone.

Dr Chan is an amazing nutritionist. She has helped me meet my protein goals, improved gut health and I have learnt so much about nutrition from her. She had helped me manage my allergies. I am grateful for her expertise and consultation

Kim Chan has been a godsend for helping me with my digestive issues. A few months ago, I was having major bowel issues. I had loose stools with frequent urgency. After a thorough analysis of my health background, Kim was able to provide a detailed dietary and supplement regimen for me. Through all of my meetings with Kim, she was always patient and made sure to answer any questions I had. Furthermore, she always included the science background information that was related to my issues. This helped for me to visualize and gain a greater understanding of my overall dietary issues. I am extremely grateful to Kim for all of her expertise, support and guidance. She is an outstanding dietician that has great knowledge of her field and truly cares for the well-being of her patients/clients.

Since working with On Ki Chan at Berry Street I’ve seen significant results in my PCOS journey. I haven’t felt this incredible since my teen years. She’s very knowledgeable and more importantly she listens to my concerns. I really couldn’t have gotten this far without her help.

Health and Longevity

Personalize your Diet

It is important to be sensitive to your culture and ethnicity and to personalize your diet so that you don’t lose a part of who you are or ignore your genetics.

You can reach longevity and be healthy by optimizing your diet and lifestyle.

You are not destined to have diabetes, hypertension or other chronic diseases that your family or relatives may have.

If you are already diagnosed with a disease, then diet & lifestyle is just as important for prevention as well as reversing it.

Start with your diet first. Look at the quality and quantity of what you are eating. I help you assess how much of each macronutrients (protein, fat, carbohydrates, fiber, water) you need and assess whether you are meeting your micronutrients (vitamins and minerals) needs. Tracking your diet and testing your digestion and gut health are helpful and recommended. Taking a closer look at your digestion starting from the top down – from the time you think of food, chewing, and digesting food, all the way down to eliminating it – this is what it takes to assess digestion.

Seeing Kim for SIBO and other liver, gall bladder and pancreas issues. She is very knowledgeable, explains things with ease and has a kind and empathetic spirit. I feel so lucky to have found her. Highly recommended! AP

I’m impressed with my Nutritionist virtual visits. My nutritionist Kim (On Ki Chan) is extremely smart, as well as personable. I like the work we do together, and I’ve already learned so much, e.g. how to naturally get more magnesium in my diet for muscle growth. There are my own responsibilities – a couple of blood tests, and following recommendations from Kim. I do those things because I’m choose to be invested in the success of this nutritional counseling. The best part is that these virtual visits are paid by my insurance, so free to me. MC

Talking with someone who has the knowledge to help me make better choices brings peace to me. Developing a trusting relationship and being able to share my concerns is helpful as well. It’s easy to stay in contact. IH
