what dont they tell you.....GREAT question!
well, I've read the whole thread - which is 99% "food related". As for me, the unexpected "negatives" had nothing to do with food...I guess I would label them general "quality of life issues" for lack of a better phrase. So, here goes, I'm about to vent a little....
1) my doctor simply wont permit me to take my other non-related medications (whether tablet or capsule form) no matter how small the pill may be. Yeah, yeah, crush them up, yada, yada...well guess what? they dont work the same when they are crushed up. Diabetes meds dont work the same, cholesterol meds dont work the same, and worst of all my BPH (I am a male patient) meds dont work the same. So, if I'm down a few pounds, what good would it do me if I'm dead from a heart attack, or if my blood sugar is yo-yoing, or if I need major prostate surgery?? By the way, I literally grilled the doctor on this issue before the surgery and the answers were "glossed over" every time. God forbid that I should come down with some other illness, cause I wouldnt be able to get any medicine in me - and obviously that will happen some day.
2) SEVERE constipation. Repeat, SEVERE. Artificial Fiber? Did not work. Prune juice? Did not work. Foods with high natural fiber? Not even close. Laxative such as "milk of magnesia"? Yeah, but its still very rough, and I really dont think its a healthy long term solution.
3) Problems with hair, scalp, and skin. Scalp and skin are very dry and itchy all the time. Texture of hair is TOTALLY different. Much thinner, much drier, not healthy hair at all. Probably losing hair.
So there you have it. My 3 big gripes, and none of them have anything to do with food and eating - or lack thereof.
Let me just close by saying that I'm FULLY aware of the need for Protein and good hydration, and I am doing eveything in my power to get the protein and the Water and the fiber in. I just dont want people to think that good intentions will always lead to the desired results. Some negatives MAY not be in your power to control.
