In the latest episode of SBS "Vitamin" aired on April 17, Secret's Hyosung attracted viewers' attention by sharing her diet tips.According to an article in Daily Kpop News, she said: "Before the diet method 'one meal a day' became popular as today, I had applied it last year. Because I love rice, I ate just one meal a day and reduced 5kg within a year.""But now, I apply two diet methods. If I eat a lot that day, I would only eat one meal a day, but normally, I eat five small meals a day to maintain weight", she added.Netizens comments varied. They include: "Both methods... sounds hard", "this is nothing complex", as well as "I think it is not easy to do".View the gallery for snapshots of Secret's Hyosung showing off her hot body during a concert in Singapore.
