Fare for the day was gluten-free food at organic and raw food eatery The Living Cafe.
And the diet-friendly meal got ONE FM 91.3 radio DJs Desiree Lai and Melody Chen recalling their most health-conscious moments.
"I've tried counting my calories using this fitness tracker that I wore like a wristband," said Lai, 33.
"It counts the number of steps I take and I had to key in the amount of food I ate. I had to log on to the Internet to find out how many calories were in one char siew pau.
"After a couple of weeks, I gave up."
Chen, 37, has attempted the juice fast, as well as diets where she "had to cut out all her carbs". But like Lai's calorie-counting misadventure, "those diets never lasted very long".
"I'm almost 60kg, though I might not look like it," she deadpanned.
"Growing up in the media has been extremely stressful, as everyone scrutinises your weight. I've done modelling and people have asked me: 'Why are you so heavy?'
"I've kind of given up on checking my weight. As long as I eat right and feel good about myself, it's okay."
Lai and Chen crossed over from sister station Kiss92 to the newly-rebranded ONE FM 91.3 last month. Lai hosts the weekday 10am to 1pm show, and Chen takes over for the 1pm to 4pm slot.
