Learning To Trust A Body That Feels Unpredictable
By a Registered Dietitian specializing in Intuitive Eating, eating disorder recovery, and functional gut health — and someone who knows firsthand what it's like to live in a body that doesn't always follow the rules.
There’s a particular kind of exhaustion that comes not from doing too much, but from never knowing what today will bring.
Will I be able to eat breakfast without my heart racing?
Will that meal I tolerated fine last Tuesday wreck me today?
Will I make it through the afternoon without the dizziness, the nausea, the bloat that makes me look six months pregnant by 4pm?
Will my body let me show up for my own life today?
If you're living with chronic gut issues, POTS, MCAS, or any condition that makes your body feel like a mystery you can't solve, you already know this exhaustion intimately.
And if you're also somewhere on the path of healing your relationship with food — trying to practice Intuitive Eating while your body sends confusing, contradictory signals — the complexity can feel almost cruel.
How do you learn to trust a body that keeps surprising you?
How do you tune inward when inward feels like a place you can't rely on?
I've sat with these questions professionally, with clients navigating these exact intersections.
And I've sat with them personally, in my own body, on my own hard days.
What I've come to understand is this: trust doesn't mean certainty.
And learning to live with an unpredictable body isn't about fixing it into submission — it's about fundamentally changing the relationship.
💛 When Your Body Feels Like the Enemy
Conditions like POTS (Postural Orthostatic Tachycardia Syndrome) and MCAS (Mast Cell Activation Syndrome) have a way of making the body feel deeply untrustworthy — not because the body is failing you, but because it is responding to a dysregulated nervous system, an overactivated immune system, or a gut-brain axis that has been stuck in alarm mode for a very long time.
MCAS, in particular, can make eating feel like navigating a minefield.
Mast cells — immune cells found in high concentration in the gut lining — can trigger reactions to foods that seem random and inconsistent.
A food that was fine yesterday causes flushing, bloating, or brain fog today.
There's no real “safe” list.
There's no predictable pattern.
For someone already working to make peace with food, this is maddening.
POTS layers in its own complexity: blood pooling, heart rate spikes and fatigue after eating can make meals feel like a physical event to survive rather than something nourishing and enjoyable.
For many people, food starts to feel like a threat — because in a very real, physiological sense, it has been.
Here's what I want to say clearly, from both my clinical and personal vantage point: the hypervigilance that develops around food in the context of these conditions is not disordered thinking.
It is a rational adaptation to genuine, repeated physical distress.
Your nervous system learned to be on guard because being on guard kept you safer.
But at some point, that same hypervigilance starts to cost more than it protects.
🌿 Intuitive Eating Was Not Designed With You in Mind — And That's Okay
Let me say something that isn't said often enough in eating disorder recovery and Intuitive Eating spaces:
The traditional framework was built largely around people without chronic illness.
The idea of eating when hungry, stopping when full, and trusting your body's cues assumes that those cues are relatively consistent and reliable.
For people with POTS, MCAS, chronic gut dysfunction, or any other condition that causes these cues to be altered, they often aren't.
Hunger signals can get blunted or distorted by so many factors- gastroparesis (when your stomach empties slowly), nausea, medication side effects, just to name a few.
Fullness arrives erratically.
What works on one day causes a reaction the next.
This doesn't mean Intuitive Eating has nothing to offer you — it absolutely does — but it means the framework needs to be adapted and applied with compassion for your specific needs.
Trusting your body in this context doesn't mean following every cue perfectly.
It means learning to be curious instead of reactive.
It means moving from "why is my body doing this to me?" toward "what might my body be trying to tell me right now?"
That is a slow, nonlinear, and genuinely difficult shift.
I know because I've made it, imperfectly, in my own body.
What Trust Actually Looks Like When Your Body Is Unpredictable
Trust, in this context, is less of a destination and more of a daily practice.
It looks less like certainty and more like a willingness to keep showing up — even when the ground feels unsteady.
Some of what has helped me, and what I've seen help clients navigating similar terrain:
Grieving the body you thought you'd have. Chronic illness involves real loss — of ease, of spontaneity, of a simpler relationship with food and movement. It’s important to acknowledge this loss and get support when needed to process your relationship with your body.
Distinguishing between listening and catastrophizing. Body awareness is a skill worth developing. Anxious monitoring is a trauma response that keeps the nervous system activated and makes gut and chronic illness symptoms worse. Learning the difference — often with therapeutic support — changes everything.
Working with your nervous system, not just your diet. For POTS and MCAS especially, the autonomic nervous system is central to symptom severity. Eating in a calm, regulated state can make a big difference in how you feel throughout the day. Practices such as breathwork, meditation, and eating consistently throughout the day to avoid blood sugar swings can be beneficial.
Releasing the pursuit of a symptom-free body as the only acceptable outcome. This can be a tough one. Often, the chronic illness journey is oriented toward fixing, eliminating, and optimizing. And while symptom management absolutely matters, when the relentless pursuit of a perfect protocol becomes its own source of suffering, it's worth asking: what would a good enough day look like? What does a life alongside this body — not in war with it — actually feel like?
The Body Is Not the Problem
Your body is not betraying you.
It is doing its best within a system that has been dysregulated, under-supported, or asked to carry more than it could hold — often for a very long time.
Learning to trust it again is not naive.
It is, I'd argue, one of the bravest and most radical things a person with chronic illness can do.
It won't be linear.
There will be days when the trust feels solid and days when it evaporates entirely.
That's not failure — that's the reality of healing in a body that is complex, dynamic, and deeply human.
You don't have to trust your body perfectly.
You just have to be willing to keep trying.
Need Support?
If you're navigating eating disorder recovery, gut health challenges, Intuitive Eating, or your relationship with food and body alongside a chronic illness like POTS or MCAS, you deserve support that holds all of it — not just one piece.
You don't have to choose between healing your body and healing your relationship with food.
Let’s figure it out together.
