From Skeptic to Streak: A Year of Intermittent Fasting

I will be honest — I started intermittent fasting to prove it was nonsense.

I am the kind of person who reads the studies, checks the sample sizes, and is deeply suspicious of anything trending on social media. When three of my colleagues started talking about their "fasting windows" last year, I assumed it was the new CrossFit: lots of enthusiasm, questionable evidence, and a shelf life of about six months.

I gave myself 30 days to try 16:8 intermittent fasting, fully expecting to write it off. I am writing this on day 365.

Month 1: The Experiment

My rules were simple. Stop eating by 8 PM. Do not eat again until noon the next day. Black coffee in the morning was allowed. No other changes to my diet — I was not going to confound the experiment by changing what I ate, only when.

The first three days were unremarkable. Day four was hard — genuine, distracting hunger at 10 AM. By day seven, the morning hunger had dulled to a background hum. By day fourteen, I was forgetting to eat at noon because I was not hungry.

I lost 1.8 kilograms in month one. Not dramatic, but I was not trying to lose weight. I was trying to disprove a hypothesis.

Months 2–3: The Data Started Talking

I am a data person, so I tracked everything. Fasting times, weight, sleep quality (subjective 1–10 scale), energy levels, and exercise performance.

By month two, clear patterns emerged:

• Sleep quality improved from an average of 6.2 to 7.4 out of 10
• Afternoon energy crashes — which I had accepted as normal for a decade — disappeared
• My morning workouts actually got better, not worse, despite training fasted
• I stopped craving sugar after dinner, which had been a nightly battle

I had my quarterly bloodwork done at month three. My doctor raised an eyebrow — in a good way. Fasting insulin had dropped from 9.2 to 5.8 mU/L. Triglycerides were down 22%. HDL was up slightly. My inflammatory marker (hs-CRP) went from 1.8 to 0.9 mg/L.

"What changed?" she asked. I told her I stopped eating breakfast.

Months 4–6: The Habit Locks In

Somewhere around month four, fasting stopped being something I was doing and became something I just did. There was no willpower involved. I woke up, drank coffee, worked until noon, and ate. The same way I brush my teeth — not because I am motivated, but because it is the routine.

My streak counter in MindFast became a quiet source of pride. Not in a gamified, dopamine-hit way — more in a "I have been consistent with something meaningful for 120 consecutive days" way. There is a difference between being motivated by a streak and being informed by one.

Weight stabilized at about 5 kilograms below where I started. I was not trying to lose more. My body seemed to find its natural set point and stay there.

Months 7–9: The Social Test

Summer holidays, family gatherings, a two-week trip to Europe. This is where most "diets" die. Intermittent fasting passed the test because it is inherently flexible.

Late dinner in Barcelona at 10 PM? Push tomorrow's eating window to 2 PM. Family breakfast on Christmas morning? Break the fast early and shorten the window. The protocol bends without breaking. I maintained my practice through every social situation by adjusting the window rather than abandoning the principle.

I missed a few days. Life happened. The streak reset and I started a new one. That is fine. Consistency over a year matters more than perfection in any given week.

Months 10–12: The New Baseline

By month ten, I stopped thinking of myself as "someone who does intermittent fasting." I was just someone who eats between noon and 8 PM. The identity shift is subtle but important — I was not fighting against a desire to eat differently. This was simply how I ate.

Year-end bloodwork confirmed the trend:

• Fasting insulin: 5.1 mU/L (down from 9.2)
• Fasting glucose: 4.8 mmol/L (was 5.4)
• Triglycerides: down 31% from baseline
• hs-CRP: 0.7 mg/L (was 1.8)
• Weight: stable at minus 5.3 kg from start

I also noticed changes that do not show up on bloodwork. My relationship with hunger changed fundamentally. I learned that hunger is not an emergency — it is a signal, one that passes if you wait. My food choices improved naturally because eating twice a day makes you more intentional about what those meals contain. And a strange, quiet confidence came from knowing I could go 16 or 18 hours without food and feel fine. It is a small thing, but it resets your sense of what you are capable of.

What I Got Wrong

I was wrong about intermittent fasting being a fad. It is not a diet — it is a meal timing practice backed by meaningful research on metabolic health, insulin sensitivity, inflammation, and cellular repair.

I was wrong about needing breakfast to function. I function better without it.

I was wrong about it being hard. The first week was hard. The remaining 51 weeks were easy — easier, in fact, than any other health practice I have tried.

What I Would Tell the Skeptics

I was you. I get it. Here is my suggestion: commit to 30 days. Not 30 days of hoping it works — 30 days of doing it consistently while paying attention to how you feel. Track the data. Be honest about what changes and what does not.

You do not need to believe in intermittent fasting to try it. You just need to be curious enough to let the data convince you. It convinced me.

365 days in. Day 366 starts tomorrow. Same as usual.
