I had the good fortune to find and work with Jillian earlier this year. I had been struggling with mild health and allergy issues for years, even consulting specialists who could barely offer any solutions, and only left me feeling scared and confused.

She had my bloodwork analyzed, and explained it in detail using a program that shows the patient in a very clear and visual way where the areas of concern are. She was always very loving and kind in her explanations and in presenting a holistic approach that includes herbal and vitamin supplements, as well as dietary and activity changes.

So far my allergy issues are greatly improving and my weight is gradually reducing. I feel more confident and in charge of my health, and although I am not perfect in all areas yet, she has been supportive and encouraging me the whole time. It is not a “quick fix” and requires work and commitment, but my health is worth it.

Thank you, Jillian!

I am a 25yo female and I have been struggling with nausea for 10+years. Throughout all of the doctors and healthcare professionals trying to figure out the cause of my nausea, I still was struggling daily. Once I spoke with Jill, she was the first person to really listen to all of my thoughts/questions/concerns and take everything into account of this big puzzle I had been trying to solve the majority of my life. I began to lose hope until I spoke with her. She is so sweet, loving and supportive and made me feel heard for the first time in years. She is much more than a dietician; she has such a wealth of knowledge that goes beyond everything I thought she could help me with. We have finally found the source of my nausea and she made sure I knew that she would be a continuous support for me throughout this process of healing. Jill is helping to teach me to be my own best healer along with all of the tools she has taught me already. I am so grateful to know her. She takes the time to get to know you and figure out the best ways to help YOU feel better. I have no doubt in one way or another she can help you feeling happier, healthier, more energetic and most importantly getting you back to feeling like your true self-and even better.

Jillian has provided me with the insight and education to make better decisions for me as an individual, based on my specific health conditions. Changes that I have made, have had an impact on my overall health allowing me to feel better both physically and mentally. Jillian is supportive, patient, and caring as I go through this journey changing how I eat in general vs. looking at it as just another diet.

I highly recommend working with Jillian. If you are looking for someone who will invest in you and your health, who is incredibly passionate and knowledgeable in the field of functional medicine and nutrition Jillian is who you want. When I first went to Jillian with a health concern I explained my symptoms to her (bloating, gas, fatigue, headaches, inability to lose weight, constipation) and right off the bat she had an idea of what was going on (SIBO). We worked together to get the necessary testing done and she was right I have SIBO. She helped me understand the antibiotics I was prescribed and also set me up with supplements that would help aide in getting rid of the SIBO. I am forever grateful for her guidance through this. I didn’t know what SIBO was when she first mentioned it to me, much less how to go about getting tested for it. She knew the steps I needed to take, the doctors I would need to work with and that I would need to advocate for myself because often times things like SIBO are over looked. It took months to get the diagnosis. Jillian was there every step of the way. From the beginning of our conversations about health and wellness she has been by my side through it all. During the months of waiting for my SIBO diagnosis she helped me work on healing my gut and taking the necessary steps to live a healthier life. I didn’t know much about functional medicine and nutrition or how to heal my body from the inside before working with Jillian. Jillian is always so easy to talk to, willing to answer whatever questions you have and will help however she can. If you have the opportunity to work with her do it. She will change your life!

Over the past few months, I have had the pleasure of working with Jillian and have found it to be one of the most valuable experiences of my life. She really takes the time to get to know your history, your day-to-day life, preferences, and goals into account when developing an individualized plan that is manageable and tweaked as needed. Jillian is easy to talk to, extremely compassionate and understanding, and explains everything in detail in a manner that is easy to understand. There’s so much research, information, and misinformation easily available to us, and it’s difficult to navigate alone what is best for us. Jillian is extremely knowledgeable in providing recommendations that are appropriate and checking in to see how effective and manageable the course of action is going. Jillian’s professionalism and area of expertise in Functional Nutrition is highly recommended and valuable to last a lifetime!

Just when you think you know someone!

I’ve known Jillian for many years as a smart, warm, kind, authentic, compassionate woman, but until recently I didn’t know her as a professional, licensed Dietician/Nutritionist. What I learned is that in addition to who she is as a person, as a professional she has a very impressive depth of knowledge and experience in her field. She works hard to get to the root cause of each individual’s unique circumstances and challenges, and she creates a plan tailored just for what you need in order to achieve your goals.
Jillian has a way of educating you and explaining things to you so that you can understand and absorb at your own level, and at your own pace. Her patience and kindness shines through, as does her genuine and sincere desire to help you to feel happy, healthy, and whole. She doesn’t just give you the tools for your journey, but she is personally invested in taking it with you and supporting you through change.
If you are ready to invest in yourself, let Jillian be the one beside you!

My health, my weight, and my happiness had been on a slow but steady decline for years when I finally reached the point of being ready to do something about it. The choice to act on healing my body was made out of love, for my family, but more liberatingly, more truthfully, and most importantly, for myself.

That choice to act happened in an instant and began a journey.

Jillian became my trusted partner and guide on this journey toward restoring my body to health. She taught me to understand what I was eating: both the cumulative effect of the mistakes I had been making and the potential healing available to me as I began to make different choices.

She coached me, advised me, encouraged me, and acknowledged me every step of the way. She shared her knowledge and turned me on to a new way of thinking about food. I have learned to replace the things that were making me sick with foods that delight, satisfy, heal and enhance my life.

While still a work in progress — my journey toward optimal health will continue for the rest of my life — I am a healthier, happier person who has transformed my relationship to food and to myself.

Transformation cannot occur if we do not address the root cause of our sickness.

I have transformed. I am grateful to Jillian for being a steadfast contributor to my healing.

I came to Jillian three months ago with a series of digestive issues and was in a general state of “not feeling good”. After our initial consult, I signed up for the 5-session virtual nutrition counseling. Over the next 5 weeks, we covered a lot of ground. The full blood work panel and analysis provided great insight into how my body was operating; Jillian used this information to create a plan for me to help get my body and state of mind back on track.

Initially, I was easily able to adjust my eating habits to the Protocol developed by Jillian, my body was responding, and physically I was feeling much better. However, the emotional component was still there. That is when we got to Session 4 about our relationship with food, stress, and strategies. Jillian spent a lot of time with me talking about our emotional attachment to food and how other tools (baths, journaling, stretching) can help mediate stress and break the cycle of highs and lows. This was so essential to my success. It really is a lifestyle change, and I am so much better for it. I feel empowered by this work and as Jillian says, “this is a massive act of self-love.”

I wholeheartedly recommend the Root Cause Method – Jillian will make you feel safe, cared for, and show you how much better life can be when we listen to our bodies.

I loved working with Jillian. She is unlike any therapist, nutritionist, or wellness expert I’ve ever worked with. She listened and worked within my comfort zone gently nudging and advising on what was right for ME. Not for others, but for ME. I loved our sessions, which were filled with informative analyses of my bloodwork, imbalances, and research around my issues. She did not focus solely on diet or exercise, she really addressed the emotional and hormonal sides as well. Her approach is thorough and life-changing. I have hired Jillian to help my children and referred her to my family and friends. I am so grateful to have found her. She isn’t just a therapist, this is her life. She lives and breathes health and wellness. That is important to me.

Jillian provided a five-star experience, and I am so grateful for the knowledge I gained after 5 sessions.
I’ve been on a weight-loss rollercoaster for the past 7 years. For the first time, I feel like I actually have the tools I need to sustain a healthy lifestyle for the long haul. From learning about what’s going on in my body to learning how to eat and properly grocery shop for my body made a world of difference in my health journey. Now I prepare meals that don’t leave me feeling sick or uncomfortable. I highly recommend Jillian’s services, especially if you’ve been trying to do it on your own and nothing has worked. Give yourself a chance to heal your body and mind. I did and I’ve been feeling better each day using the tools I’ve learned from Jillian. This experience was one of the best investments I’ve made for myself. Health is wealth. So let’s get wealthy together by getting to the root cause.

Jillian is so much more than your average nutritionist. A friend recommended Jillian when she saw me struggling to lose weight. I immediately set up an appointment. I’ve had a toxic relationship with food for way too long and it was time for a change. Right away, I knew Jillian was going to put me on the right path to feel and eat better. I knew I needed to get healthy, but Jillian made me realize there’s so much more to it than just eating well. She really dove into my relationship with food, my anxiety, my feelings and me as person and changed things for the better. I’ve been on this journey for about two months now and I already feel like a different person. The best thing about all of this is she is going through this with you. Her recommendations aren’t just things she researched, she’s tried them for herself and that made me feel at ease. Give up on the diet fads because going to Jillian isn’t just another fad, it’s a total lifestyle change and worth every minute.

For years I have been told that I must lose weight because my health was at risk. I would lose 10 or so pounds, but never stuck with it long enough. This past June, after a knee replacement and my fourth back surgery, my legs had become so swollen that I could not even walk. Each day, I watched the scale go higher and higher. It was very scary.

During a visit to my cardiologist, he expressed concern and and told me that if I didn’t do something immediately I could wind up in the hospital; My skin had become so tight, and it could tear. I left his office feeling depressed and frightened.

I have known Jillian Acosta since she was born, and knew that she was helping many people to improve their health and lose weight. I called her in desperation and she responded immediately with love and concern. I was finally READY to listen and to learn about how my food choices were affecting my health. I thought I was making healthy choices, but I soon realized that I had much more to learn.

To date, after just four months with Jillian’s guidance, I am down 45 pounds. 4 sizes, and my prescription medications have been cut in half. This is NOT a diet, but truly a life-changing way of eating.

Jillian taught me that I can enjoy the occasional treat with no guilt, and she taught me how I can incorporate my favorite foods into my healthy lifestyle.

The Root Cause Method is a far better way for your health and weight loss — without pills, shots, surgeries, packaged “meals”, and restrictions.

I highly recommend Jillian Acosta and The Root Cause Method to anyone who is READY to listen and learn and practice the guidance that she provides.

The work way deeper than the style diet or types of foods. Jillian creates a safe space to explore the root cause of overeating. In all my years of therapy I never realized so much about my connections to food and emotions as I did while working with her. I started out coming to avoid surgery for gallbladder, which I did! And I ended up having a stronger connection to myself and to a more healed version of myself. It’s worth every dollar.

I have spent 4+ years with worsening pain in my stomach, bloating, and nausea to the point where it had become pretty much a constant in my life. I went to my primary doctor to look for a solution and was told everything seemed normal and sent on my way to continue with the symptoms. I went to a gastroenterologist where they ran an ultrasound and an endoscopy and came back to me with the same results, everything seems fine…we’ll send you a pill to help with the symptoms but there is nothing we can do to treat it. As my symptoms continued worsening and my appetite continued decreasing because eating was guaranteed to worsen my symptoms, I continued searching for a solution and I came across The Root Cause Method website. I am so so incredibly grateful to have found Jillian. After our first session, I started eliminating foods that she said would likely help and within that week there was already a decrease in my symptoms. And that’s before even doing the blood work up and getting a full food protocol!! Once the blood work results were in, she reviewed everything with me and explained everything in detail. My symptoms improved even more. We discussed psychology and the impact that our mental health has on our physical health; she worked with me on techniques to help reduce my anxiety and gave me recommendations to help me on my path to healing. This was such a significant component for me; the pain was pretty much gone at this point but after this is when the bloated feeling started to reduce even more. I have raved about Jillian to my family and my friends and I truly cannot recommend her enough! The passion that she has for helping people to heal and the love and empathy that she pours into her work is evident, and that makes all the difference!

Jillian was amazing! I had such a wonderful experience working with her and looking forward to our continued work. I was going through a lot of life challenges (a move, a toddler and new baby) and she was with me every step of the way – keeping me accountable, yet so compassionate that life happens and supported any misstep I had. I’ve made so many positive changes in general and several of my lab markers completely stabilized! Highly recommend her to anyone ready to made true lifestyle changes that will only optimize your quality of life. So thankful!
