In 2013 David Sandy had come off a year of foot problems that had caused his weight to go to 440+. He was in the process of shutting down his law practice. He had a side business called Nameperfection (http://www.nameperfection.com) that generated some income selling brandable domain names for startups on the internet. He briefly tried selling life insurance before deciding to focus on the domain name business that seemed to be going fairly well until Google and industry changes made it necessary to regroup.
He had started to make progress when his mother was diagnosed with small cell lung cancer in 2014. She passed away in July of that year. In 2015, David struggled with health problems himself and managed to control them with a Ketogenic diet that allowed him to lose down to 355.
However, the diet, like all diets before, had stopped working and made him cold and sapped his energy. His thyroid levels had started to become hypothyroid.
In early 2016, he found information indicating that fasting could help control blood sugar levels and tried not eating for 18 hours. Seeing the dramatic effect even such a limited window of not eating had he figured that maybe fasting could work for weight loss.
He tried longer and longer fasting periods and passed below 240 on his last 20 day fast, a weight he figures he has not seen since sixth or seventh grade. In addition to the domain name business that has picked up, he has started a personal blog at http://prudently.com to talk about fasting and his life experiences up to this point.
