And now Frankie Essex is showing off the fruit of her labours, flaunting her fantastic figure on her recent Greek getaway.
The 29-year-old reality star was looking trim in a halter neck black bikini as she fooled around in the sea in Mykonos on Monday.
Her high-cut briefs and emphasised her toned and flat tummy, making sure her recent weight loss was clear for all to see.
Frankie, who is set to release a fitness DVD after getting in shape and beating depression - lost almost three stone in 12 months , dropping from a size 14-16 to a size 8.
In a heartbreakingly honest interview with The Sun Online, she also said: "This time last year I didn't want to wake up the next day, I couldn't get out of bed.
"I was in a hole, drinking and going out. I was burying my head in the sand, I was really in a bad way, overweight and in a bad relationship that I wanted to get out of."
