Khloe Kardashian
Khloe Kardashian was once a big curvy woman. She isn’t all that anymore as she has slimmed down. The transformation was met with a mixed reaction as many men loved the curvy Khloe more. She owed her weight loss to training five days a week with trainer, Gunnar Peterson. During the time, she allegedly drank plenty of water to counter her appetite. Khloe spoke to People magazine about her experience of controlled eating, “I kind of eat what I want, but in portion control, which I never knew before. It’s really hard. You have to train your body to eat less. Your eyes are bigger than your stomach.”

Snooki achieved global fame for her stint in the reality TV show, Jersey Shore. Before trying her hand on the small screen, Snooki studied to become a veterinary technician at a community college. Contrary to popular belief, Jersey Shore wasn’t her first TV show; it was “Is she really going out with him?” Snooki wasn’t the skinniest one around during Jersey Shore. So, when we caught a glimpse of Snooki after the birth of her first child, we were shell-shocked. The woman shed around 50 pounds and went through an astonishing metamorphosis. She credited the weight loss to her daily training program and the intake of healthy food.

Chris Pratt
Chris Pratt became a bona fide A-lister after the successive releases of two blockbusters, Guardians of the Galaxy and Jurassic World. In order to prepare for his role in Jurassic World, the actor was obligated to lose 60 pounds. The difficult objective was made possible because of his commitment to a strict diet plan formulated by nutritionist, Phil Goglia. When he retained his six-pack abs, Chris famously posted a shirtless selfie and captioned it, “Six months no beer.#GOTG Kinda douchy to post this but my brother made me.” We are sure the women weren’t complaining. It took a long time for Chris Pratt to reach the pedestal he is currently in right now and he has the right to post as many shirtless selfies as he desires.
