Here's my take on it:
as a person with metabolism issues (hypothyroidism), I have to work out twice as long and diet twice as hard the average person (
) to lose weight. I'm a person with an eating disorder and I've spent a some time (I've been "dieting" or preocupied with food since I was 13 years old) working with this issue.
I KNOW fasting FEELS good at the time, there IS reason one eats to lose weight. When you fast, the body shuts down and stops processing because it says "hey, I need to hold onto this food, etc. cuz you're starving me". Sure, you're going to lose some water weight (fast)but, in the long run it doesn't work.
Plus it always made me sick to do this!! Good luck and that's my 2 cents!
