17 days of water fast, ate a herring, suddenly flu-like symptoms

Hello, I went from 84.7 to 74.9 Kilograms within 17 days, then I decided to have a meal, one meal that wouldn’t break ketosis but would ‘replenish’ myself; fish is rich in omega3 fatty acids, B12, etc…

After eating a mere two fillets of raw herring from the supermarket (about 200 ~ 250g) with onions and half a squeezed lemon juice, my nose is dripping like crazy, I used a whole toilet paper roll in half a day, and I’m sneezing a lot. I don’t have any other symptoms. Then, when I looked at my weight it suddenly spiked up to 76.8? What magic is going on here. Is this refeeding syndrome?

Sounds like histamine toxicity from fish

Answer

After 17 days, I don’t think you’re supposed to eat solids like that. I think 2 days of bone broth, very steamed veggies, and maybe avocado. I wouldn’t eat protein until day 3. And raw? Your asking even more of your digestion system.

Answer

When you don’t eat, your stomach acid becomes like weak tea. (An exaggeration but you get the idea). You need to slowly refeed and your digestive system rebuilds.

I do OMAD. You don’t get the incredibly rapid losses, but you also eat every day and the weight loss continues at a steady pace. I was losing about 2-3 lbs a week. You don’t take breaks to refeed. It’s just normal living and eating healthy food to fullness in a short window. Might consider it. I’ve done for 4.5 years. Lost my weight in 6 months and just love living and eating on this schedule. I’ll never do back to frequent eating. The longest EF I’ve done is 72 hours. I don’t get hungry but have headaches and difficulty sleeping - even with electrolytes. I do longer fasts only for deeper autophagy. OMAD is great for weight loss and maintenance.
