Holistic Gut & Digestion Solutions: Reclaim Your Health & Freedom

Tired of Your Gut Calling the Shots? Discover Lasting Digestive Harmony!

Hi, I’m On Ki “Kim”, and as a holistic Registered Dietitian Nutritionist, I’m passionate about helping you unlock vibrant health through the power of a happy gut and a thriving liver. For too long, the narrative around digestive issues has been one of managing symptoms, not truly addressing the root cause. My mission? To empower you to break free from the shackles of digestive discomfort, reclaim your energy, and enjoy life without the constant worry of where the nearest bathroom is.

Your Gut: The Core of Your Well-Being

It’s no secret that gut health is foundational to our overall well-being. From our immune system and hormone balance to our mood and energy levels, a healthy gut truly dictates so much more than just digestion. But in today’s fast-paced world, our digestive systems are under constant assault – from stress and processed foods to environmental toxins and antibiotic use. The result? A symphony of uncomfortable symptoms like bloating, gas, constipation, diarrhea, and a pervasive feeling of just not being “right.”

Understanding the Gut-Liver Connection

Beyond digestion, your gut works in tandem with your liver, a vital detox organ. A healthy gut ensures proper waste elimination, reducing the burden on your liver, while a well-functioning liver helps process toxins that can impact gut health. Optimizing both is key to true holistic wellness.

The Power of Calm: Eating for Optimal Digestion

One crucial, yet often overlooked, aspect of gut health is the state in which we eat. Think about it: scarfing down lunch at your desk, rushing through dinner while driving, or eating during a stressful meeting. When we’re in a state of stress – activating our “fight or flight” response – our body prioritizes survival over digestion. Blood flow is diverted away from the digestive tract, enzyme production decreases, and gut motility can be compromised. This is why you might experience bloating or discomfort even after eating seemingly “healthy” foods.

As a systematic review published in Nutrients highlights, stress significantly impacts gut function through the gut-brain axis, influencing everything from gut motility to permeability. This reinforces the importance of cultivating a calm eating environment to optimize digestion and nutrient absorption.

This means putting away distractions, taking a few deep breaths before meals, and truly savoring your food. It’s a simple yet profoundly impactful step towards a healthier gut.

Navigating the "Noise": Your Personalized Path to Wellness

The world of diet and nutrition can be overwhelming, with conflicting information and trendy fads around every corner. One day, gluten is the enemy; the next, it’s dairy. It’s enough to make anyone feel lost and confused.

From Confusion to Clarity: My Commitment to Your Evolving Needs

My role is to be your trusted guide. Together, we’ll cut through the “noise” and determine what the best diet plan is for you at this moment. This isn’t about rigid rules or restrictive eating; it’s about discovering what truly makes your body feel its best. And we’ll embrace the understanding that your dietary needs may evolve as your symptoms and health goals change. This is a dynamic, ongoing process, and I’m here to support you every step of the way.

Real Results, Backed by Science

My strategies are rooted in the latest scientific research, including Randomized Controlled Trials (RCTs) and systematic reviews. For example, evidence from numerous RCTs consistently demonstrates the profound impact of dietary fiber on gut microbiome diversity and function, with specific fibers acting as prebiotics to fuel beneficial gut bacteria. Similarly, systematic reviews have illuminated the role of various probiotics in managing conditions like Irritable Bowel Syndrome (IBS), showcasing the potential for targeted supplementation when diet alone isn’t enough. My recommendations are always evidence-based, ensuring you receive the most effective and safe guidance.

The Missing Piece: Understanding YOUR Unique Digestive Story

You’ve likely tried countless diets, supplements, and quick fixes, only to find temporary relief or even more confusion. This is where a holistic approach, grounded in science and personalized to you, makes all the difference. I believe in taking the time to truly listen to your unique health journey. We’ll delve deep into your medical history, lifestyle, dietary patterns, and symptoms to uncover the root cause(s) or reasons to explain some of your digestive distress and get you back to being healthy.

Beyond Symptoms: My Holistic, Science-Based Approach

No more guesswork. No more one-size-fits-all solutions.

My approach is always food-first, emphasizing nutrient-dense, whole foods that nourish your body and support optimal gut function. We’ll explore what you can eat and tolerate now, and equally important, why. Understanding these nuances is key to building a sustainable and effective plan. And where diet alone isn’t sufficient, I’ll thoughtfully recommend science-backed supplements to bridge nutritional gaps and support specific physiological processes.

Functional Testing: Uncovering Your Root Causes for Precision

Many of my clients come to me feeling frustrated because conventional tests haven’t provided answers. That’s why, in addition to a thorough health history and dietary analysis, I leverage cutting-edge functional lab testing to gain a deeper understanding of what’s truly going on inside your body. These aren’t your typical ‘normal range’ tests; we look at optimal levels and specific markers that reveal hidden imbalances. This personalized approach allows us to pinpoint root causes, rather than just managing symptoms. Depending on your unique needs and symptoms, we might explore

Advanced Digestive Insights: Functional Stool Testing

This comprehensive test (e.g., GI-MAP) provides an in-depth look at your gut microbiome, identifying imbalances in bacteria, parasites, yeast overgrowth, digestive enzyme function, and markers of inflammation and intestinal permeability (leaky gut). Understanding your gut’s unique ecosystem is paramount to building a targeted healing plan.

Hormone Balance & Fertility: DUTCH & Mira Fertility Testing

For women experiencing hormonal fluctuations, irregular cycles, PMS, PCOS, or fertility challenges, advanced hormone testing like the DUTCH (Dried Urine Test for Comprehensive Hormones) offers a detailed picture of sex hormones, adrenal hormones, and their metabolites. For those tracking fertility more closely, Mira Fertility can provide valuable insights into your ovulation cycle.

Comprehensive Wellness: Blood Work & Nutrient Analysis

Beyond standard blood panels, we can delve into specific markers for nutrient deficiencies, inflammatory markers, blood sugar regulation, and other indicators that reveal underlying physiological imbalances. This helps ensure your body has all the building blocks it needs to thrive.

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!

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.

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.
