Holly Madison – Diet, Exercise, & A Corset/30 Pounds 

Being someone who has been associated with Playboy for so many years, Holly Madison is expected to never have problems with being chubby. Well, that might be the typical conclusion but Madison herself had already experienced gaining a lot of weight and this was because she was going through pregnancy. To lose the weight that she had gained, Madison made sure that she consumed around 1,100 calories per day and hit the gym as often as possible. Wearing a corset also helped her with the loose skin that she had. Needless to say, her discipline and hard work had paid off! Madison was able to release two best-selling memoirs in 2015 and 2016.
