Losing weight is a very personal story, but when the results are favorable, everyone wants to show off how many inches they have lost, or dress sizes they have dropped. For some, working on their health helps them control signs of depression and for others, their medical doctors strongly prescribe losing weight for healthcare.

Who would know the pressures of losing weight better than famous people who face cameras all day long. The actors and actresses are often cast in movies that require them to lose weight and buff up. For this, diets and physical trainers do wonders, but so does lap band surgery and plastic surgery in some cases.

Here’s our list of top celebrity weight loss inspirations and their amazing transformation….

Russell Crowe: Diet and Increased Physical Activity

As medical doctors will tell you, putting on weight and rapidly losing it is not good for one’s health, but it is an occupational hazard for many actors and actresses who have to do it to bag acting jobs. Take Australian actor Russell Crowe for instance, who had to pack on the pounds for his 2017 movie Boy Erased.

Russell then lost a lot of that weight and is looking much slimmer now. The Gladiator star is no stranger to rapidly gaining and losing weight for movies. In 2016, when he weighted 270 lbs, he had to lose 53 pounds in just 7 months for his upcoming movie, The Nice Guys.
