Famous folk always seem to be dropping weight and toning up in the blink-of-an-eye. And while us mere mortals probably can't afford an army of personal trainers, dietitians, private chefs and detox retreats like they can, we can still learn a few valuable weight-loss lessons from their success stories.
Here, we round up five celebrities who are looking better than ever, and reveal the secrets, tips and tricks behind their image overhauls…
The reality TV star looks as gorgeous as ever since losing weight and water was an important factor. Khloe claims she drinks 5 litres a day and is encouraging her younger sisters to do the same. Khloe said: "I go to a trainer five times a week, and on the weekends, I do cardio or whatever I want to do."
She added: "I kind of eat what I want, but in portion control, which I never knew before."
Sam managed to drop 14lbs in 14 days with the help of Amelia Freer's book Eat. Nourish. Glow.
Freer has said: “It’s very nice for me to see the results that I do get with my clients.
She continued: “Usually for people who have that weight to lose it can happen quite dramatically, quite quickly. But it’s absolutely done safely, nothing faddy or starvation or deprivation happening here,”
Freer tells clients the importance of making their meals from scratch and putting a lot of natural, fresh produce into their diet.
One of the famous Geordie Shore weight loss success stories, Charlotte dropped an astonishing 2-and-a-half stone, going from a size 16 to a size 6.
Charlotte has opened up about the secrets to her weight loss, saying: "I just eat healthy and I don't over-indulge like I used to."
"I try and do my DVD at least four times a week and I see my personal trainer maybe once a week if I'm not too busy," she said.
Charlotte admits she still loves her McDonald's on cheat days but doesn't over-eat anymore.
Charlotte's fitness DVD 3 Minute Belly Blitz is available now.
Snooki dropped down to 99 pounds in November, less than two months after giving birth. 99 pounds is a healthy weight for the petite 4'8" Jersey Shore star.
Her trainer previously opened up and said that she was decreasing her carbs and overall calorie intake. She was also spending a lot of time in the gym.
He explained: "We're also doing plyometrics, cardio, etc. Right now it's all really geared for weight loss, then she wants to focus on lean muscle mass once she's married."
Michelle definitely has one of the most desirable figures going, and it appears a lot of it is thanks to the SoulMateFood delivery service.This allows you to create your own healthy menus which are then delivered to your front door. The 6-day meal plan costs £150.
Michelle also opened up about the gym: "I try and go to the gym as much as I can".
