After years of struggling with autoimmune issues and getting nowhere with traditional medicine, I found nutritionist Kay Spears— total game changer. Her holistic, personalized approach helped me uncover root causes to start healing from the inside out. She saw environmental connections my doctors and specialists missed and guided me with smart nutrition strategies, supplement advice, and genuine care. Kay's guidance also helped me keep fit as my metabolism has slowed in recent years, offering practical solutions that actually work. She sorts through the overwhelming array of supplements and wellness products on the market and recommends and prescribes natural, healthy options I can trust. With a little hard work, dedication, and Kay's support, I got results. This is long term. I’m now healthier, feeling fit and like myself again. If you're ready to do what it takes and looking for someone who truly understands the power of nutrition, Kay Spears is committed to assisting you on your journey to wellness. Thank you, Kay!

After telling her I managed to get myself down from 650 to under 450 on My own by going through my own work changing my diet and stop overeating and going from a guy that was eating about 5 lb of food at every sitting to now a guy that eats enough to feel full on veggies peanuts and cheese every 24 hours. She basically told me how I wasn't doing it right and I need to follow her plan. Which was very upsetting and frustrating to hear because I wasn't looking to change my complete diet I was trying to find a way to tweak it more so it might have a bit more flavor and how to do it hopefully but she didn't care she just wanted to push her agenda and diet and what I mean by her diet is she had said diet plan that she gave everybody. But you know anything about food you know food is not a one-size-fits-all thing what I do for my diet may not work for your diet. Also it didn't sound like she was willing to take into consideration the fact that certain foods are like alcohol to an alcoholic to me in I need to be careful of those foods she didn't take time to learn any of this. She just wanted to push her agenda of the diet and how it was right everything I was doing was wrong. It took a lot of hard work and effort for me to get to where I am today and it took a lot of Grace from a loving God to get me here. It sounded like all of that was discounted the few minutes that I talked to her just so she could tell me about her wonderful diet plan that she does for all of her clients.

I came to Kay with several different digestive issues happening and a hormonal imbalance. After working together for 6 months and following her guidance, I cleared up a lifetime of digestive issues and lost 30lbs of excess weight. One of my goals from working with Kay was to learn how to feed my body best moving forward and for my husband and I to eventually be able to become pregnant. We are currently pregnant with identical twin girls due later this year and I have felt GREAT 99% of my pregnancy. All of this I attribute to the tools I learned through working with Kay!
