12 stone 14 pounds. Day 21. End of the fast. Lightest I’d been in thirty years.
Forty-eight hours later: 13 stone 8 pounds. Seven point eight pounds back on. In two days.
I wasn’t shocked — I’d done the research. But seeing the number still stung. Here’s what actually happens during refeed after an extended fast. The science, the surprises, and the one thing that vanished after 25 years.
The Office Return: Why You Don’t Storm Back In
Your digestive system’s been on a three-week holiday. Feet up, margarita in hand, not a care in the world.
Monday morning, you don’t storm back into the office and immediately present to the board of directors. You ease in.
First meal after 21 days: Vegetable soup. Warm, gentle, easy to digest. An hour later, poached egg on rye. Light protein. No shock to the system. By evening, normal meal — Caribbean chicken, brown rice, vegetables.
Dr. Federica Amati’s research shows your gut lining and microbiome need time to adapt. Gentle, easy-to-digest foods help wake up your digestive enzymes. Rush it — skip straight to a heavy meal — and your gut goes on strike. Cramps, bloating, possibly the loo for an hour.
Three bowel movements on Day 1. No negative symptoms. Digestion waking up nicely.
But the scale. That bloody scale.
The Glove Box Refills: Where the Weight Comes From
Day 22: 13 stone 4 pounds. Up 4.2 pounds from fast end.
Day 23: 13 stone 8 pounds. Up 7.8 pounds.
Day 24: Holding at 13 stone 7.
Alan Aragon’s work explains this perfectly. First week weight gain during refeed is glycogen plus water. Not fat regain.
Think of glycogen like £50 in the glove box for car parks and coffee. Fasting emptied it completely. Now you’re refilling it.
One gram of glycogen holds three to four grams of water. That’s the weight.
Your muscles store about 300-500 grams of glycogen. Your liver stores another 100 grams. Add it up: 400-600 grams of glycogen, times four for water retention.
That’s 1,600 to 2,400 grams — 3.5 to 5.3 pounds — just from glycogen refill alone.
Add sodium from food (water retention), blood volume returning to normal, gut contents (you’re eating again, obviously), and boom. Five to eight pounds in 48 hours.
Expected. Normal. Not fat.
But I’m not going to lie — watching the number climb still felt like failure for about ten minutes.
The Fermented Food Strategy: 20 Varieties, One Goal
I’d been planning this for weeks. Twenty new fermented food recipes. Kimchi, sauerkraut variations, pickled vegetables, kefir-based dishes. All bubbling away in my cupboard, waiting for refeed.
Professor Tim Spector’s research at King’s College London shows fermented foods reduce inflammation differently than fibre alone. Different mechanisms, both essential.
Professor Nicola Segata’s work confirms your microbiome diversity drives metabolic health. Bad bugs love junk food — it’s easy to feed them. Good bugs are picky, specialized. They need variety.
I ate fermented foods with every meal:
- Kimchi with eggs
- Sauerkraut with lunch
- Kefir smoothies
- Pickled onions with dinner
Day 1 refeed: Digestion stayed calm.
Day 3: Bowel movements regular. No bloating. No discomfort.
Day 7: Gut felt stronger than before the fast.
Twenty fermented varieties means 20-plus bacterial strains. More diversity equals better digestion, mood regulation, appetite control, inflammation reduction.
Fermentation isn’t a fad — it’s foundational.
The Gout Mystery: 25 Years, Then Nothing
This is the bit nobody prepared me for.
Gout for 25 years. Since I was in my twenties. Visible uric acid crystal buildup on my big toe joint. Lumpy, uncomfortable, occasionally painful. Allopurinol for years until I stopped it in February 2024.
Day 24. Refeed Day 3.
I looked down at my toe. Crystals. All but disappeared.
Not reduced. Disappeared.
I put on Birkenstocks — couldn’t wear them for years because of the toe pain. Walked four miles. No flinch. No discomfort. Nothing.
Twenty-five years of crystal buildup. Gone in three days of refeeding.
Autophagy Doesn’t Clock Off at First Bite
Here’s what I think happened.
Autophagy doesn’t stop the moment you start eating. Dr. Federica Amati’s research shows it ramps down gradually, not instantly. Your body’s still processing cellular debris for days, possibly weeks post-fast.
The fast created the cleanup. The refeed provided nutrients for repair.
Autophagy continued during refeed, clearing those old uric acid deposits like the bin lorry finishing its round.
Visible proof: fasting benefits don’t end at first bite. You’re shifting phases, not ending healing.
Weight Stabilisation: The Actual Numbers
Up five pounds over the first six days. Then lost three pounds over the next four days.
Settled at two pounds gain from fast end.
Final stabilisation: 13 stone 9 pounds. Two pounds heavier than Day 21. Seven pounds lighter than refeed peak.
Throughout this, I maintained intermittent fasting. Started 12:12 — twelve-hour eating window. By Day 7, naturally tightened to 17:7 — seventeen hours fasted, seven-hour eating window.
Body didn’t demand constant food. It adapted.
Professor Tim Spector’s work on time-restricted eating shows early shifted regimes — finishing meals by 6-7 PM — show better biomarker outcomes, especially glucose control.
I wasn’t trying to be perfect. The window just compressed naturally.
One slip: Nut binge on Day 5. Cashews, almonds, walnuts. Ate too many, too fast. Gut racing for the exit within an hour.
That’s what happens when you overwhelm a recovering digestive system. Lesson learned: ease in, even on Day 5. Your gut’s still waking up.
Apart from that? Calm. No bloating. No discomfort. Fermented foods did their job. Soups provided gentle bulk. Gut bacteria woke up without drama.
Why the Microbiome Matters During Refeed
Weight rebound during refeed is normal. Expected. Temporary.
Professor Nicola Segata’s research explains why. During extended fasting, certain gut bacteria go dormant. They don’t die — they’re just not thriving.
When you reintroduce food, especially fibre-rich fermented foods, those bacteria wake up and multiply.
A diverse microbiome is linked to:
- Better mood
- Improved digestion
- More stable appetite signals
You’re not just refilling the glove box. You’re rebuilding the entire internal ecosystem.
Think of it like a garden. You’ve let it rest over winter. Now you’re planting seeds and feeding the soil. Results take time, but the foundation matters.
🎯 Key Takeaways
- Refeed weight gain: 3-7 pounds expected first week — Mine peaked at 7.8, settled at 2. Normal.
- Glycogen refill: 1g glycogen holds 3-4g water — That’s the weight, not fat.
- Fermented foods: Essential, not optional — Speed gut recovery, reduce bloating risk.
- Autophagy continuation: Doesn’t stop at first bite — Gout crystals clearing Day 3 = proof healing continues.
- Eating window: Compressed naturally from 12:12 to 17:7 — Body regulated appetite without force.

“Free 7-Day Fasting Blueprint in the description — walks you through refeeding protocols.” “Refeeding after extended fasts requires care. Start gently, monitor digestion, don’t rush. If you’ve fasted beyond 72 hours, speak to your GP about safe refeeding protocols, especially if you’re on medication or have existing health conditions.”
