Severely autistic people enjoy gathering information and conducting research. In 2013, Henk ter Heide noticed that obese people eat 650 grams a day while gaining only 5 grams. Five grams a day equals 2 kg per year, which is 20 kg over ten years.
He wondered if it’s possible that people aren’t eating too much but burning too little fat. He started with some unusual exercises to investigate this.
