I have, I lost 20lb at the rate of 1lb a week in spite of, eventually, stuffing myself silly with food I didn’t want.
At first I put it down to the stress of moving house though it went well and I didn’t feel particularly stressed. Then I got worried because I couldn’t stop it and was also having digestive issues that seemed to indicate some sinister cause.
I saw my doctor who put me on the two week pathway. Eventually, after scans, ‘scopies north and south plus blood tests, my body was found to be in perfect nick for my age.
The doctor concluded that as soon as I got moved, it would stop, and it did, straight away.
Your mind definitely affects the workings of your body. But see your doctor you should, you can feel well but not be.
Incidentally, I was delighted with the weight loss when I knew I was OK but sadly, most has returned!
Good luck!
