Chapter 7

Cheat Day is the seventh chapter of Volume 1 of the manga Dumbbell Nan-Kilo Moteru?

Summary
Sakura Hibiki, Soryuin Akemi and Uehara Ayaka are eating lunch on the rooftop of their school's building. Hibiki mention how she is only eating 2 big meals a day, but Akemi states that's sumo wrestlers grow larger using the same diet.(Eating big meals during an empty stomach also known as "Binge eating" it raises the blood sugar levels by a large portion which causes insulin to be secreted from the pancreas. As excessive insulin is secreted the body will turn in it into fat). Akemi suggest a "Bodybuilder diet" in where a person eats many meals through out the day. This is to prevent the blood sugar level to rise by always having food in the stomach. Akemi talks about how she has 5 meals per day including snacks (protein)

Same ingredients can have different calorie count depending on how it is prepared: Steamed < Boiled < Sauteed < Deep fried

Hibiki decides she will go on a "Bodybuilder's diet" for summer but quickly loses confidence as she won't be able to eat her favorite foods.

Akemi reassures Hibiki by telling her about "Cheat day" were a person can eat any food they would like during that day. The "Cheat day" is done ounce a week and the reason why people do it is to trick the body into over eating. Hibiki is motivated and begins the diet.

Later on after school they eat at a restaurant where Hibiki start her new diet with a cheat day. Akemi tries to warn Hibiki she's doing her diet wrong, but Ayaka tells her it's pointless.

Also we learn that Hibiki prepares her own meals and wakes up really early during the morning. And tells Ayaka that's why she is always late at school.
