Daniel_Stuckey writes "Senior Editor of Motherboard Brian Merchant went an entire month without eating regular food. Instead, the journalist whisked up a concoction called soylent, an efficient take on the future of nourishment and nutrition. Merchant says: 'It was my second day on Soylent and my stomach felt like a coil of knotty old rope, slowly tightening. I wasn't hungry, but something was off. I was tired, light-headed, low-energy, but my heart was racing. My eyes glazed over as I stared out the window of our rental SUV as we drove over the fog-shrouded Bay Bridge to Oakland. Some of this was nerves, sure. I had twenty-eight days left of my month-long all-Soylent diet—I was attempting to live on the full food replacement longer than anyone besides its inventor—and I felt woozy already. ... By the third week of Soylent, not eating food seemed normal. I saw a doctor, who said I was healthy; I was still losing weight, but nothing serious. Yet, given that a daily mixture of Soylent contains 2,400 calories, both Rob and Dr. Engel thought it was odd that I’d shed so much. Dr. Engel said that given my weight, height, and body mass, I should only require about 1,800 calories a day. I could still be adjusting to the new diet, or I could have such a hyperactive metabolism that before Soylent, I was tearing through hundreds of extra calories per day and staying trim.'"
