- "I LOST 160 LBS IN 11 MONTHS WITHOUT SURGERY. NOW I RUN ULTRAMARATHONS." Andrew Dasselaar (1975) was a successful journalist until December 6, 2012. On that day, the first of many panic attacks forced him to reevaluate his life choices: his career, his relationships, and above all, his habit to use food as an analgesic. It took Andrew 11 months and 4 days to lose over 70 kg (160 lbs). He didn't resort to surgery or swallowing pills. Instead, he decided to face the pain that was making him overeat in the first place. For Andrew, the key to losing weight was learning to let go.
