A protein-rich diet helped the Japanese female artist lose more than 30 kg after giving birth

Shoko Nakagawa, 41 years old, is Japan’s leading multi-talented female artist, working in many roles such as singer, actress, manga artist and YouTuber.

After attracting attention with the announcement of giving birth to twin boys last September, Nakagawa continued to cause a stir when she publicly revealed her spectacular postpartum body transformation. In a post posted on Instagram on September 28, she shared: “It’s been about a year since I gave birth. From 78 kg right before giving birth to the twins, I’m now only 47 kg, which means I’ve lost more than 30 kg.”

Posting a photo comparing her pregnancy belly with her current slim figure along with an image of a scale displaying the number 47.4 kg, the female artist wrote: “Even though I was a bit shy, I was surprised by this change, so I decided to publicize my weight for the first time. A person’s weight can really change in an amazing way. That is truly the miracle of giving birth, even at the cost of one’s life.”

According to the health monitoring book, she weighed 75 kg on the day of admission and when she stepped on the scale the day before giving birth, the number was up to 78 kg. “It’s shocking,” she said.

The female artist also talked about the difficulties of being pregnant with twins due to struggling with severe edema. The nose is unusually enlarged due to swelling, and the ankles are swollen, itchy and painful. Due to previous infertility treatment, she continuously took medication and hormone supplements, and was unable to diet while preparing for pregnancy, so her weight increased steadily. “At the beginning of my pregnancy, water retention made me gain more weight, my body became very heavy and tired. However, I felt extremely relieved when the two babies were born healthy,” Nakagawa added.

She said she lost nearly 15 kg in just about 2 weeks after giving birth, and also revealed her diet method. During about 8 and a half months of breastfeeding, she ate enough to have nutrients to feed her baby. Even though she feels depressed every time she looks in the mirror, she still puts the children’s health first. When her children started teething, biting and milk production decreased, she decided to wean and begin a weight loss regimen.

The artist emphasized absolutely not skipping meals because this negatively affects hair and skin, and always focuses on protein supplementation. “Because I don’t like to exercise, I hardly exercise. I also don’t like boiled chicken breast, so I created other menus. In my daily diet, I combine salmon with foods good for beauty, sometimes use some suitable dishes from convenience stores and persevere a little every day,” she said.

According to Nakagawa, unlike when he was in his 20s, losing weight at age 40 is really difficult. “The goal is not just to lose weight at all costs, but I want to no longer feel sad every time I look in the mirror, and I’ve worked hard to this extent,” she said. The female artist expressed her desire to lose about 1-2 more kg, but because she is in the process of raising a child, she will try to maintain her current weight without pushing herself too hard.

Shoko Nakagawa announced her marriage to someone outside the entertainment industry in April 2023. She announced her pregnancy in May 2025, then confirmed that she was pregnant with twins and welcomed two children into the world the same year.
