Pink gets real about her post-body weight, exposing the problem with BMI standards.

Singer Pink is getting beautifully real about her “post-baby body” after discovering that she is deemed “obese”.

In an honest Instagram post the 37-year-old mother-of-two said:  “Would you believe I’m 160 pounds (72kg) and 5’3″ (160cm)?”

“By ‘regular standards’ that makes me obese.

“I know I’m not at my goal or anywhere near it after baby two but dammit I don’t feel obese. The only thing I’m feeling is myself,” she added.

Alongside a workout photo, the musician warned others to stay off the scales.

According to an online BMI calculator, Pink is classified “overweight” (at 72.5kgs and a BMI of 28) and advises her to lose between 7.96kg and 24.55kg “to obtain a normal body weight”. Yes, an outrageous 24.55kg.

However more than 200,000 fans supported the mother of two’s message.

“You look amazing Pink! You are a huge inspiration for my own body goals,” said one follower.

Another said: “Very inspiring….I’m with baby number two and three months to go and it drives me bonkers but your post really gives me peace to not be so hard on myself. Even afterwards!”

“You look great – to think you’re obese is laughable,” said another.
