Miss Universe 2015 Pia Wurtzbach is among curviest stars to ever walk this planet.
With many obviously jealous of her physique, Pia finally gave in, sharing her secret via Instagram.
According to Pia, it all boils down to three things: Cold therapy, fasting, and working out daily.
But she maintained: "Even if you do the cold plunge or even if you're doing the fasting and you're doing the most challenging fast and working out once or twice a day that will all go to waste if you don't eat right."
She added, "Basically ganu'n lang naman 'yun. It doesn't have to be so complicated... Health and fitness is actually pretty easy, you just go back to basics. So you keep yourself active, you eat well and you stay hydrated. If you follow those three I think you'll be good."
Sharing more ideas on achieving the perfect bod is her boyfriend Jeremy Jauncey.
"The most important thing as you start this health journey is to start eating healthy food as regularly as possible," he said, going on to urge those interested to remove all processed food from the diet.
"Any food that come in packages -- generally try to avoid those. And if you find that the (label) of these foods have ingredients that you can't read, or you can't pronounce, then don't eat them," he reminded.
