On April 12 KST, Hyeri updated her YouTube channel with a new video, where she went out for Korean beef omakase with her filming crew.

After enjoying the course meal, Hyeri commented, "I'm full already. It makes me sad." A staff of the filming crew then said, "Did your stomach shrink because you've been dieting? How long do you need to be on a diet?"

Hyeri answered, "I need to really cut my weight down for my next project." Next, Hyeri revealed, "But actually I weigh more than I look. I did an InBody assessment the other day. I will reveal everything in detail."

The star then showed her InBody assessment results for the camera. The results read that Hyeri currenty weighed 54.1 kg (119.3 lb), with her muscle mass being 22.2 kg and her body fat measure being 25%. [Hyeri is 167 cm (~ 5 ft 7 in) tall.]

Hyeri also shared that a few months ago, when she met up with BLACKPINK's Jisoo on her YouTube channel, she had actually weighed more, at 57.2 kg.

The singer/actress then promised viewers, "I will diet really hard and show you my transformation."
