The time on the clock was 11:47 a.m. It took me thirteen minutes to be permitted to eat. I was sitting at my desk with a very particular, very undignified kind of rage that only those who have missed breakfast for eight weeks in a row will recognize. I had been up since six, had already written two articles, and had taken the dog for a walk. I wasn’t sold on this version of intermittent fasting by the wellness accounts.
I was genuinely curious going into those ninety days. Curious, not desperate. There are claims all over the place, such as improved mental clarity, more consistent energy, weight loss that lasts, and an ambiguous promise of longer life. Intermittent fasting is discussed online with an almost religious confidence. Either you’re doing it incorrectly, or you do it and change. So I did it. 16:8, each day for three months. No days of cheating. Take no shortcuts.

The first two weeks were challenging in both unexpected and expected ways. To be honest, the hunger was tolerable. The mood was uncontrollable. By day four, I was becoming irrationally irritable, snapping at people for no apparent reason, and becoming silent during conversations. According to a University of Illinois Chicago study that was published in Nature Reviews Endocrinology, intermittent fasting done correctly is generally safe. However, the influencer version of events, in which the transformation is always seamless, rarely discusses the early adjustment period.
Black coffee developed into a coping strategy and ritual. You either get used to or don’t like the hollow, acidic burn of drinking it at eight in the morning on an empty stomach. On certain days, I did. I didn’t every day.
Something changed by the fifth week. Not significantly; there isn’t a single morning when everything comes together. However, the mist cleared. The rage subsided. Without keeping track of the minutes, I began to reach noon. In comparison to what the before-and-after posts had prepared me for, I was losing weight slowly—perhaps a pound and a half every two weeks. According to a study published in Cell Metabolism, intermittent fasting can sometimes hasten muscle loss but doesn’t substantially outperform regular calorie restriction for weight loss. The transformation photos often leave out that particular detail.
The emotional aspect is what no one discusses and what really caught me off guard. At week seven, I became aware that my perspective on food had changed, not only in terms of when I could eat but also in terms of why. Between waking up and noon, fasting allows you to spend an odd amount of time in your own head, and some of what emerges is uncomfortable. A 38% dropout rate is mentioned in clinical literature for a reason. Many people find that the protocol works until it doesn’t, at which point it completely stops working.
I felt cleaner in the mornings than I had in years, had lost about twelve pounds by the end of ninety days, and was more conscious than ever that this particular eating style calls for a certain temperament. It works well for people who don’t have erratic blood sugar, eat late naturally, and work alone. It doesn’t work for everyone, and it’s possible that the loudest supporters are just those who fit in well. When you look past the headlines, the science is far more cautious than what the Instagram version implies. It’s worth trying. It is worthwhile to approach honestly. It is not worth considering as a general solution.
