A reminder of the objectively superior body build.

Consuming less food means you don't have to spend as much time shopping, cooking, and eating, so you have more free time.
Consuming less food means you don't have to spend as much money on food, so you don't have to work as much to sustain your existence, so you have more free time.
Consuming less food means there are more resources for others in times of need, making you generous and selfless.
Consuming less food means less food has to be produced, reducing the complexity of the economy and making it easier for your folk to be self-sufficient.
Consuming less food means fewer animals are murdered to satiate you for a few hours. If you are vegan, consuming less food means fewer animals die from farming practices and food transport / fuel burning.
Consuming less food means that famine resulting from climate change will be less of a shock to the body, reducing initial discomfort and hardship.

>IT MAKES YOU WEAKER AND LETHARGIC!
No respect for self-sacrifice? Don't be selfish, prick. A martyr's life is the best life.

>GRUG MUST HAVE BIG MUSCLES TO THROW ROCK!
Muscles require additional food and great labor to maintain. The only muscles you have should be from routine physical work. Gym-going is a waste of time that could be better put to education, activism, mental discipline, and ascension from materia.

>THIS IS JUST AS BAD AS BEING OBESE!
It's the opposite of obesity. Obesity comes from action, skinniness comes from inaction. Obese people have to put in more mental and physical effort to eat more than average-weight people, whereas skinny people have to put in LESS effort. Obese people *work* to get that fat.

>YOU ARE SHRINKING THE ECONOMY! BUY BUY BUY!
Good! The dogma of endless growth and engorgement is a cancer on the earth. Simplicity is better.
