Peter rejoices whenever he puts on more weight. He loves how his protruding belly moves and delights in the fact it gets in his way.

At 170 cm and weighing a hefty 113 kilograms, Peter, who requested that his last name not be published, is on a quest to become even more corpulent. He documents his weight gain on his blog, GitBigger.com, under the pen name "Stupidgit."

Big dreams ... "gainer" blogs are a growing phenomenon.

"I love how my weight feels when I run, falling and shaking my body shortly after each step..." the 23-year-old Lexington, Kentucky, resident, writes on his blog. "The only thing I love more than being fat, is getting fatter."

As hard as it is to understand, Peter is not alone in his desire to gain weight. The internet is rife with "gainer" blogs, plus dating sites and discussion forums that glorify big bodies, with names such as Fatnesse Follies, Growing Larger, BiggerCity.com and BellyBuilders.com.
