What To Expect

A Personalized Nutrition Program. Backed by Labs. Built for Life. 

Understand Your Baseline

Start with a comprehensive walk-in blood test and in-app health questionnaires. Together, they uncover what may be driving your symptoms — from inflammation and nutrient deficiencies to gut or immune imbalances.

  • 70+ lab tests — 3x more than the average annual physical
  • Lab centers near you — 2,000+ patient service centers nationwide
  • Fast, walk-in appointments — no referral needed
  • Smart intake forms covering — lifestyle, gut health, eating habits, and pain
Your registered dietitian reviews your results and designs a plan specifically for you. No guesswork. No cookie-cutter protocols. Each Healthnix dietitian is carefully selected for their expertise in chronic pain, gut health, autoimmune care, and functional nutrition.
  • Insights from your labs
  • Targeted food recommendations
  • 5-day meal plan + personalized grocery list
  • Lifestyle tips based on your daily routines and real life
  • Educational content and guided behavioral exercises designed to put you in the driver’s seat of your own wellbeing
This is where the real transformation begins. For 12 weeks, you’ll have expert guidance and easy-to-use tools that help you turn insights into progress.
  • Kickoff Consultation (Week 1, 60 min): A deep dive into your labs and intake with your dietitian to finalize your personalized plan. Available via video or phone — for maximum convenience.
  • Midpoint Check-In (Week 6, 30 min): Review progress, fine-tune your plan, and troubleshoot anything that’s not working.
  • 24/7 Dietitian Chat Support: Your registered dietitian is your cheerleader in your pocket. Ask anything — from “What should I pick from this menu?” to “Why am I feeling this way?”
  • Symptom & Food Tracking: Spot unique patterns in how your body responds to food. Even identical twins can react differently — tracking helps you decode what’s right for your body.
  • Weekly Educational Content: Bite-sized videos and audio clips from leading doctors, dietitians, lifestyle coaches — plus real patient stories. It’s not “in your head.” You’re not alone. Feel heard, seen, and supported.
As part of the Healthnix program, you’ll retain 1 full year of access to the Healthnix app for continued symptom and food tracking, plus all educational content — so you can keep learning and building healthy habits at your own pace.

Just a quick email to let you know I’ve now had my first call with Nicole in which she spent over an hour talking me through everything and giving advice. Nicole then followed up our call with a lengthy, really informative email which has made me feel very positive about my new eating plan and the start of becoming much healthier and hopefully reduce my daily pain etc. I will be having a call with her again towards the end of July but she has told me I can contact her any time if I need any extra help which is really good to know. I just wanted to share my positive experience with her this morning.

I’ve been sticking to the eating plan since my call with Nicole on 29th July and have lost 13lb in weight so far.

I have found my time with Healthnix useful in regards to the two telephone appointments with my dietician, Hillary. She has provided thoughtful, tailored guidance to help reach my goal of losing weight and improve my health whilst living with arthritis, without completely cutting out the foods I enjoy. Hillary has a good knowledge of food and nutrition, and was able to suggest lots of new foods and dishes I could eat to help me lose weight by improving my diet. She also provided information about foods to avoid or cut back on because they can trigger inflammation or are generally unhealthy. I’m grateful for her expertise and support.

Male User, 61

I was lucky enough to have two 1 hr consultations with Hillary regarding dietary issues. I benefitted from some very good nutritional advice to aid with weight loss, cholesterol control and have subsequently introduced some new items into my diet to further enhance these aims. Although my diet was acknowledged as being good overall, Hillary helped me with some fine tuning that I’m sure will benefit me in the long term. I feel I learnt some valuable things from Hillary and found her to be very professional, thorough and a pleasure to talk with. I do feel my energy levels, which were very poor due to constant pain or at best severe discomfort, have started to improve. I suffer from arthritis in my entire spine and knees and although the prognosis is one of further degeneration I’m hoping my dietary adjustments may help slow the process and I know that I will be avoiding foods that can contribute to increased inflammatory problems.

Changing my diet and nutrition has made me feel better. I do believe the change is making a difference to my general well-being.

I first had a conversation with Hillary about 9 weeks ago. I had just found out I had osteoarthritis and was in constant pain and feeling quite despondent. Hillary spoke to me about what I hoped to achieve, I said I would like to be healthier, to not be in constant pain and to hopefully slow down the symptoms of arthritis. We spoke about what food I was eating, likes/dislikes. Hillary then went through how I could make positive changes to my diet. I have taken on board everything she said, I love my breakfast of yoghurt fruit and muesli every morning. I have cut out almost all ultra processed foods. I have lost 2kg already really easily, as I don’t really get hungry anymore. My pain has reduced enormously due to the changes in my diet. I had a thorough blood test at the start of the programme, this showed cholesterol was high and thyroid levels were high. I’m getting these retested in a couple of weeks by my GP and I am hoping that the changes I have made will show these levels to be at a more normal level. I can’t thank Hillary enough for giving me the confidence I needed to make these changes.

My whole eating and food world has been turned upside down! I wish I had done this sooner. Although I thought I was a good eater, as I don’t eat out much or do fast foods, I had no idea until I started taking pictures how much I was eating and how healthy it can be. So my grocery list is altered to include fruits which I hardly ate and more veggies and protein daily. Going to the grocery store is interesting as I am trying to stay organic with everything I buy. I am feeling more energetic daily and I am never hungry. I started weight training exercises last week and do cardio treadmill 15″ daily during the week. I will build up to more exercise weekly. Also – I’ve invested in two titanium pots for cleaner eating. So my kitchen items are transforming. Even at my age, I want to live healthier and feel better. I was becoming dormant and spiralling downward as many of my age group have. I’ve also realized that we really are what we eat! A good diet lends itself to less medications and letting my body heal itself. Glad I am doing this… it’s a healthy style of eating and living for life.

I had my 1 hour meeting with Dr. Fierro, and she was excellent. She gave me many practical suggestions that were easy to implement and have already helped with my sleep and digestion.

Female User, 74

I know it’s only been one week (barely) but in just this little time, I’m feeling so much better. Can you imagine how much better I will feel in a month.. two months.. six months? Amazing. My head (brain) is thinking so clearly. It’s crazy. It seems if I encounter an obstacle or issue, I have the energy and know-how to solve or remedy it – almost immediately. Is this your experience as well?

All my GI pain disappeared in the first 3 weeks!

I’ve noticed that it (food recording) gives more structure to my day!

I’m two weeks into my Healthnix journey and already feeling the difference, less fatigue, less bloating, and no more midday naps! After years of trying restrictive diets that hurt my mental health, this approach feels supportive and sustainable. My RD helps me find realistic swaps (even at restaurants!) instead of cutting things out. Finally, a way of eating that actually works for me.
