Actor Jo Yeo-jeong, 45 kg, reveals morning swim and toast-and-egg breakfast routine

Actor Jo Yeo-jeong has offered a glimpse into her daily routine for staying in shape.

A video featuring Jo discussing her everyday life and self-care tips was recently posted to the YouTube channel "PDC by PDC."

Jo said she woke up Tuesday and swam for about 20 minutes. "If I swim too long, the goggle marks show up and I can't film," she said. She added that she rushed home afterward and had a slice of rice toast and an egg for breakfast.

Jo said she keeps up the same eating habits even on days when she is not filming, making a point of eating healthily on a regular basis so she does not have to lose weight drastically before a shoot.

Because of her small frame, she said even a 1-kilogram change in weight is very noticeable. "Since my frame is so small, 1 kilogram is not just 1 kilogram. People with a small build like mine will understand," she said.

She added that her friends tease her about worrying over a single kilogram, but said she has no choice, explaining why she keeps such a consistent watch on her body.

Jo is listed in her profile as standing 163 centimeters tall and weighing 45 kilograms.
