Hi neohdiver, welcome to the forums. I was very interested in your post. I too have hashimotos and in the three months before I found this diet I was steadily, and scarily, gaining weight despite never eating more than 500 to 1300 calories.
After 8 /9 weeks of this diet I began increasing my calories to 900 – 1200 calories a day and find I am still fat burning (I use ketostix to check) and slowly losing the last of the belly fat. This happens if you start eating FAT! I know, it is counterintuitive but NECCESSARY!
If you are thin you could well be a TOFI – thin outside fat inside – Michael Mosley was.
I would get all your tests redone now and again in 4 weeks. I know the fat is scary, it took me 2 weeks to dare to eat it, and so far I have lost 2 stones 8lbs and have a BMI of 21.7. Like I said, the ketostix still show I am fat burning. If you look at Bill1954’s posts – he’s the person we all look up to – you will see his cholesterol rates dropped after 4 weeks into this diet. As for his other results….well check them out!!
Diabetes and hypothyroidism are closely connected – they are both metabolic problems so you were unfortunate to inherit from both sides of your family. You aren’t the only person who has decided to do 16:8 at the same time as fast 800. It makes complete sense!
Please keep posting about your progress as we all love to hear about people’s successes. If you have any queries there is always someone on the forums ready to help.
Good luck on your journey – not that you need luck on this diet – stick with it and see those numbers change!
🙂
