The glucose sensor and the question it finally answered

He had worn the sensor for three months and had a screen full of mountains. He had read enough forums to know that his lunch was "wrong" and his dinner was "right" and that he should "minimise variability." None of it had changed how he felt. He had begun to suspect that the sensor was the most expensive accessory he had ever bought for being mildly anxious about food.

He stopped looking at every meal. He picked one question — why he felt unfocused at 11am on weekdays but not weekends — and asked a research synthesis tool to read the literature with him. He paired the readings with two weeks of his own morning data. He stopped optimising. He started understanding one thing.

The work was a single, narrow question and two careful weeks of pairing his own morning sensor data with a sourced reading list a research synthesis tool helped him build. He did not change his diet during those two weeks. He read. He noted what surprised him. At the end he had two paragraphs in his own words about his own mornings — not a protocol, an explanation. The protocol came later, slower, and held.

He stopped opening the sensor app at lunch. He kept opening it before meetings.
