Abstract
A mid-life (“around fifty”) comic essayist, Hiroe Uda, is busy every day with her husband, two children—one in junior high and one in elementary school—housework, childcare, and work.
Now in her late forties, she realized she was still carrying her post-pregnancy weight and that losing weight had become even harder. Her blood pressure was rising, and health concerns were growing.
So she decided to take action!
Under the guidance of the highly sought-after diet coach Koichiro Nogami, whose appointments are nearly impossible to get, she took on the “Three-Day Monk Diet.”
No hard work or self-denial required! You can eat rice, sweets, even fried foods.
What you need is “a system” and “a bit of ingenuity.”
By losing weight in a healthy way, her self-esteem improved, and her life changed.
This is Uda’s real-life manga documentary of her diet journey.
