The Daughter Who Would Not Stay
The Moon went to her Mother one evening with a very reasonable request. She wanted a dress.
Not just any dress, of course. The Moon had taste. She wanted something beautiful, something worthy of the night sky, something made from silver-blue cloth that would shimmer softly when she crossed the heavens.
Her Mother was short and round, with careful hands and the worried forehead of a woman who had measured many things and trusted very few of them. She stood in her sewing room among bolts of fabric, spools of thread, pins, ribbons, and a dressmaker’s dummy waiting patiently in the corner, as dressmaker’s dummies do. They are excellent at waiting. Less impressive at conversation.
The Moon lifted a length of silvery fabric and held it against herself.
“This one,” she said. “This would be lovely.”
And it was lovely. The fabric caught the light like water at dusk. It looked as if it had been woven from mist, tide, and secrets.
Her Mother looked at the cloth. Then she looked at her daughter. Then she looked at the measuring tape in her hand and sighed the sigh of someone about to be practical in the face of beauty.
A Gown With No Measurements
“How can I make you a dress?” her Mother asked gently. “You are never the same size.”
The Moon frowned.
“One night you are full,” her Mother continued. “Another night you are half yourself. Some nights you are only a thin silver curve. And some nights I can barely find you at all.”
The Moon looked down at the fabric. She had not thought of this as a problem. She was simply the Moon. She grew. She faded. She returned. Her changing was not misbehavior. It was her nature.
But her Mother was right. A dress made for one phase would not fit another.
A gown cut for fullness would hang strangely when she was slight. A gown made for a slender crescent would tear when she became round and bright again. There was no single measurement that could hold her.
The Moon did not need one perfect dress.
She needed someone to understand that she changed.
When The Kitchen Becomes Confusing
This old little fable may explain something modern people keep trying to solve with lists, charts, and mild despair.
You eat something one week and feel fine. Maybe not skipping-through-a-meadow fine, because let’s remain grounded. But fine enough. No obvious punishment from the digestive department.
Then you eat the same food another week, and your body reacts as if you have insulted an ancient council.
Bloating. Cramping. Fatigue. Fog. Pain. Constipation. Diarrhea. That strange heavy feeling where lunch appears to have moved in permanently and started receiving mail.
And the question comes quickly: “Why can I tolerate this sometimes—but not others?”
It is a fair question. It is also the question that can make a person feel slightly unhinged. Because the food did not change. The recipe did not change. The portion did not change. You may even have eaten it from the same bowl, because apparently we are gathering evidence now.
But the body receiving the food may not have been the same.
The Body Changes Its Shape Too
This is especially true for people with fibromyalgia, nervous system sensitivity, food sensitivities, IBS-like symptoms, or bodies that prefer to behave less like machines and more like weather.
Food does not enter a blank system. It enters a body already shaped by sleep, stress, hormones, pain, inflammation, activity, blood sugar, and whatever emotional nonsense happened yesterday that your body has filed under “urgent.”
Very organized of it. Very little transparency.
So the same meal can land differently depending on the day. A food that felt safe on a rested, lower-stress day may feel completely different when you are underslept, premenstrual, flaring, overstimulated, or running on fumes and a suspicious amount of determination.
This is not always about the food being “good” or “bad.” Sometimes it is about timing. Sometimes it is about total load. Sometimes it is about the phase your body is in when the food arrives.
The Moon’s Mother could not make one dress because her daughter kept changing shape.
Your body may be doing something similar.
The Hormones Holding The Clipboard
Since we are speaking of the Moon, we may as well invite the menstrual cycle into the room. It was already outside, adjusting the thermostat.
Hormonal shifts across the menstrual cycle can affect digestion. Estrogen and progesterone do not limit themselves to reproductive matters, because apparently specialization was too much to ask. These hormones can influence gut motility, sensitivity, bloating, constipation, diarrhea, reflux, and abdominal discomfort.
In plain language, hormones can change how quickly food moves through the digestive tract and how strongly the body feels what is happening there.
Progesterone, which rises after ovulation, can slow digestion for some people. This may contribute to constipation, fullness, sluggishness, or that charming sensation that your meal has become part of your long-term infrastructure.
Around menstruation, prostaglandins can stir things up in the other direction. They help the uterus contract, but they can also affect nearby smooth muscle, which is one reason some people notice looser stools, cramping, nausea, or the famous digestive event no one put on the calendar but everyone somehow attends.
Add poor sleep, stress, or a fibromyalgia flare, and the threshold can drop even lower. The nervous system and digestive system are in constant conversation. When the body is already alarmed, depleted, inflamed, or sensitized, it may not process food with the same calm efficiency.
Same food. Different internal weather. Different result.
No One Failed The Dress Fitting
The compassionate reframe is this: your body is not necessarily being inconsistent. It may be being responsive.
That does not make it convenient. Responsive bodies are inconvenient in the way weather is inconvenient. You can plan a picnic, but the clouds may have other ideas and absolutely no respect for your spreadsheet.
Still, there is relief in understanding the pattern. If your tolerance changes across your cycle, during stress, after poor sleep, or in a flare, that does not mean you imagined the good day. It does not mean you imagined the bad one either. Both may be true.
Instead of asking only, “Can I tolerate this food?” you might ask, “Can I tolerate this food today?”
How did I sleep? Where am I in my cycle? Am I near my period? Am I flaring? Am I stressed in a way I have been politely ignoring? Has my body been trying to whisper something before it had to start throwing cookware?
This is not about becoming obsessive. It is about becoming more accurate and less cruel to yourself.
The Moon was not difficult because she changed.
She was the Moon.
Your body may also need different care in different phases. Not because it is broken. Not because you are doing everything wrong. Not because salad has developed a personal vendetta, though some days the evidence is compelling.
Maybe the question is not, “Why did this food betray me?”
Maybe the gentler question is, “What phase was my body in when this food arrived?”
And maybe that is where the wisdom begins: not in forcing one perfect dress to fit every version of you, but in noticing the version of you standing there today.
