yuji22, on Valentine's Day 2012 I stopped eating chicken 'cold turkey'. One month later I stopped eating egg yolk. I had stopped eating beef since July 2005.
Now, buddy, 6 months after I stopped eating chicken in 2012 I got a stroke and spent 71 days in hospital. During that time I lost around 30 pounds in weight. Why? The kinda vegetarian foods the hospital fed me was revolting. Curried split peas whole with Basmattie rice-raisins, curried cauliflower and some tasteless small beans. One Saturday afternoon I threw up just after exiting the dining room. The next day I was afraid to eat and so I fasted. The following day the dietician put me on a scale and ordered me to eat. After some thinking, we worked out a diet of eggs, fish, tuna sandwich and fruits.
I was still losing weight after returning home. My family-relatives convinced me to return to protein-rich chicken and, my wife being Muslim, I would request a piece of beef once in a blue moon. I've picked up some weight but I'm still about 20 punds short of my pre-stroke reading.
