Losing weight is a tough challenge for anyone. A lot of people believe that celebrities have it easy because they have access to trainers and chefs. But just because you have resources doesn't make the willpower any stronger.
Plus, you've got media outlets monitoring your every move. If you lose weight, you're too skinny. If you gain weight, you're "ballooning." There's no easy way to escape the public eye when it comes to weight loss.
However, celebrities like Rebel Wilson and Mama June have successfully shed some weight and managed to keep it off!
