I always told people that if you just look at it as a "diet" and make it seem temporary you're doomed to fail. It has to be a complete and permanent diet adjustment. Yeah you're going to be hungry as you body adjust to human portions but you're better for it. I used to inhale 3 or 4 IHOP pancakes and eggs, now I have to normal size ones and start the 3rd and 1 bite in I already feel full and ate too much.  Of they actually tried properly for 2 weeks straight the results would show four themselves and they would melt the planet off.
