A man who thought he was a "fat ugly loser" after years of bullying has hit back by taking up modeling - and now strips down to promote plus size positivity. <br /><br />Photographer John Savoia, 31, says he has been overweight all his life and was mercilessly mocked for his size through school. <br /><br />He was particularly ashamed of a "fat lump" on his neck and stretched the tops of his t-shirts to hide it - and then he was teased for that.
