Everything about me sucks!
In fact, I don't have a single good quality! 
50lbs...is way off though...more like 30lbs...
I guess you've never dieted before.
If you've never experienced lingering, prolonged hunger before....
you're in for a terrifying awakening.Your mood and feeling of well being will diminish BIG TIME. prepare to feel miserable for the next few months.
Lower calories = lower testosterone = severely reduced sex drive.
Your motivation and excitement for anything in life will disappear.
You'll feel 100x worse while looking only slightly better. Initially, the weight loss and visible changes occur rapidly....followed by a LONG HAUL....weeks of unnoticeable psychical changes as the scale weight continues to drop. Only once you get under 10% are the changes noticeable....
But you're not going to make it that far.The diet will teach you one thing......it will demonstrate how heavily we rely on food for emotional comfort. Reality kicks in when dieting. The delusional thoughts present while "Fat and Happy" are gone......
