The female photographer is also a friend.
In an exclusive interview with The New Paper on Sunday, Miss Sim said the calendar is not trying to send the message that it's all right to be obese.
"It's not a question of whether it's okay or not to be plus-sized. We know that the obese are at risk for health problems," she said.
"But if you are obese even after taking care of your diet, cutting down on junk food and sweet drinks, and also exercise, we want to show that it's not the end of the world."
Last week, the HPB revealed the findings of the latest National Health Survey, showing that 10.8 per cent of Singaporeans are obese.
This is up from 6.9 per cent in 2004.
A person is obese when he or she has a body mass index of 30 or more.
Being obese is a reflection of poor health, mainly as a result of a poor attitude, poor understanding of what it takes to be fit and healthy, laziness and ill discipline.
But this BAB? calendar may work well though. Similar to pictures of throat and mouth cancers, ulcers.. on cigarette packs.. the disgusting pictures of women oozing fat may make many want to puke, and lose appetite, or encourage them to lead better lifestyles.
