Hi there! I’m Tiffany, and I’m a Board-Certified Registered Dietitian who’s dedicated my career to something I’m deeply passionate about: helping people heal their relationship with food and their bodies. Every single client I work with has their own unique path and I approach each client relationship with genuine respect for wherever they are in their recovery process. One thing that sets my approach apart is my commitment to education. I believe you deserve to understand the “why” behind every recommendation I make. When I suggest a nutrition change, I’ll explain exactly how it supports your brain, strengthens your muscles, boosts your immune system, balances your hormones, improves your gut health, and enhances your digestion. Because when you understand the science, even challenging changes can become more manageable. I also recognize that many of my clients are dealing with more than just their eating disorder. That’s why I specialize in creating individualized treatment plans that take into account other health challenges you might be facing - whether that’s GI disorders, food allergies and intolerances, or autoimmune conditions. My mission is simple: to provide you with the compassionate, science-backed support you need to reclaim your relationship with food and find true healing. Because you deserve nothing less than a full, vibrant life - and I’m here to help you create exactly that.

Even with all that your body has endured, it still WANTS to trust you and restore metabolic rate. It has to have adequate nutrition for this to happen.

You’re not going to jeopardize your clients recovery by validating their medical story. But you most certainly might, when you poopoo all their “fear foods and associated symptoms” as a treatment resistant patient. Two things can coexist. Someone can fear foods because of ED adjacent reasons AND fear them even beyond that from legitimate side effects. Another two-parter. You can believe that your client experiences these effects AND that they have given you the great honor of walking alongside them and pursuing recovery in spite of these increase challenges. It might take creativity and a unique route, but isn’t that true of every story to some extent? And if we’re not able to believe that these things can coexist, how are we any less black and white than the eating disorders we support clients in recovering from?

Here’s something most people don’t realize about anorexia.

When someone restricts food, the “dopamine hit” often isn’t about pleasure. It’s about relief. Relief from fear , anxiety, fullness, unpredictability, or feeling out of control. The brain learns that eating less = safety, and dopamine reinforces that pattern even though it’s harmful to the body.

Neuroscience shows that in anorexia, dopamine circuits are often tied more to anticipating and protecting oneself from anxiety and terror rather than to enjoyment of food. In other words, the brain can reward avoidance because it’s relief from what feels terrifying.

The hopeful part is this: These pathways can shift in recovery. As the body is nourished and the nervous system feels safer, dopamine responses gradually move back toward real reward, connection, and pleasure.

Please don’t mistake that recovery is learning to love food. It does involve nourishing the body and the brain to experience safety (or less fear) with nourishment again. This takes time so be patient with yourself and your brain.

This used to be the cover of a notebook that I used when I was working on my graduate thesis. P.S. even though I loved my topic (MBTI types and eating disorders) and participants, my thesis was so stressful to work on and coordinate for so many reasons, literally cried out of frustration once when speaking with one of my thesis advisors. After competing my thesis, I ended up ripping off the cover and framing it. All this to say, the reason I kept the cover is because it resonated. The seemingly insignificant things you do today matter. There might be days where going out of your comfort zone mean using creamer in coffee instead of drinking it black, or choosing to put pb on your bread when it wasn’t part of your meal plan or going out to get pizookies on Tuesdays with acquaintances even though you can’t tell if you even like the taste because it’s so anxiety provoking. These steps matter and contribute to your future freedom.

Starvation itself suppresses insight, flexibility, and motivation AND classic and modern research demonstrates that under-nutrition has effects of:
• Obsessive thinking
• Rigidity
• Anxiety and depression
• Reduced capacity for decision-making

These effects can only start to repair after re-feeding begins and sustainably cannot happen without beginning to restore nutrition first.

The example with lactose here is a simple one, but this is often just an example of a tip of the iceberg scenerio. These challenges might extend to whole food groups or it might be certain proteins, specific fibers or other properties within a food or countless foods that might cause legitimate quality of life impacting reactions that make it feel impossible to have a varied diet while also consuming adequate quantity. Having an RD who understands that it’s not JUST ED related food fears that make expanding variety challenging, and that being able to expand the variety without having to consider quality of life impacting side effects is ultimately a luxury (and unfortunately not something many who have EDs + chronic illness have the opportunity to be able to experience) can be validating, and most importantly open the door to game plan how we can navigate variety in the context of your health story.

Fasting may lead to short term weight loss, but it also causes PROFOUND negative impacts of increased fasting blood sugar and cortisol (stress hormone) by almost 1/3rd, as well as increased levels of a form of cholesterol (LDL) associated with cardiovascular disease, triglycerides, and your heart rate.
