Pre-diabetes. HbA1c elevated. Fasting glucose creeping up. My GP said it was genetic, progressive, a one-way street to Type 2 diabetes unless I started medication. I didn’t accept that. Five years later, my bloods tell a different story. HbA1c below 5.7%, fasting glucose optimal, and a note from the same GP: “You have successfully reversed any previously indicated risk of diabetes through lifestyle interventions.” Here’s what they don’t tell you about pre-diabetes — and what I did to reverse mine.
The Diagnosis and What I Was Told
- Blood test results came back. Pre-diabetic. HbA1c elevated, fasting glucose trending the wrong direction.
GP’s verdict: “It’s genetic. Progressive. One-way street to Type 2 unless we medicate.”
I’ve got family history of diabetes. The genetic argument made sense on paper. But something didn’t sit right. If it was purely genetic, why were metabolic diseases spiking globally? Why were people in their twenties getting Type 2?
I wanted to know if lifestyle could actually reverse this. Not manage it. Reverse it.
What I Actually Did
- Started 18:6 intermittent fasting. Occasional 24 to 48-hour fasts. Non-UPF diet. Real food. No refined carbs, no sugar.
I tracked everything myself and took it to my GP. HbA1c and fasting glucose every six to twelve months. Wanted proper medical oversight, not guesswork.
2024: Blood test. HbA1c markedly decreased.
2025: Blood test. HbA1c below 5.7%. Non-diabetic range. Fasting glucose optimal.
Two years of consistent work. Five years from pre-diabetic to optimal. And my GP’s note confirmed it.
The Results: Five Years of Tracked Data
Here’s what the numbers showed:
- 2020: Elevated HbA1c (pre-diabetic range), fasting glucose creeping up
- 2024: HbA1c markedly decreased
- 2025: HbA1c below 5.7% (non-diabetic), fasting glucose optimal
This wasn’t a quick fix. It was two years of sustained effort with proper medical tracking. But the reversal was real. Documented. Not anecdotal.
Why This Works: The Mechanism
Pre-diabetes isn’t genetic destiny. It’s driven by insulin resistance. Your cells stop responding to insulin. Sugar piles up in your blood. Your pancreas works harder to compensate. Eventually, it can’t keep up.
Fasting gives your cells a break from constant insulin spikes. They start listening again. Non-UPF food removes the processed rubbish driving resistance in the first place.
I tracked HbA1c and fasting glucose through my GP for five years. Research from 2022 found that time-restricted eating significantly improves insulin sensitivity in pre-diabetics. My results align with that.
Pre-diabetes isn’t a life sentence. It’s a warning. One you can reverse.
🎯 Key Takeaways
- Pre-diabetes is reversible — Five years of NHS data showed HbA1c moving from elevated to below 5.7% (non-diabetic range) through fasting and non-UPF eating.
- Insulin resistance is the driver — Type 2 diabetes develops when cells stop responding to insulin; fasting and real food restore insulin sensitivity.
- Consistent effort over time — Reversal took two years of sustained 18:6 fasting, occasional extended fasts, and eliminating processed foods.
