Doumu Kobayashi, 40 years old, is a mangaka who has been working on Meshi ni Shimashou for three years. He has gained weight due to his love for gourmet food and now wants to use this as inspiration for his next manga series. His goal is to lose 15 kg in half a year by following various diet plans, including eating fatty foods, intermittent fasting, the GLP-1 injection diet, and adopting a full-blown Rizap lifestyle. Kobayashi's nonfiction manga will document his journey as he tests these different diets and gets closer to unraveling the mysteries of weight loss as his deadline approaches.
