In her new film ‘Black Swan’ Natalie Portman portrays a ballet dancer who wins the lead in ‘Swan Lake’. The already petite Natalie lost 20 pounds to play this part and it made me think about the weight gains and losses actors go through to turn into their characters. They seem to be able to change their bodies in only a matter of months! Gaining weight doesn’t seem that difficult to me, it’s the losing that requires the hard work. However, according to alli review losing weight quickly doesn’t have to be hell anymore. Next to a change in nutrition and more exercise, fat blockers can make you lose weight much faster. Could this be the Hollywood’s secret?
