>> My mental performance is also higher. My inbox and to-do list quickly emptied. I 'get' new concepts in my reading faster than before and can read my textbooks twice as long without mental fatigue. I read a book on Number Theory in one sitting, a Differential Geometry book in a weekend, filling up a notebook in the process. Mathematical notation that used to look obtuse is now beautiful. My working memory is noticeably better. I can grasp larger software projects and longer and more complex scientific papers more effectively. My awareness is higher. I find music more enjoyable. I notice beauty and art around me that I never did before. The people around me seem sluggish. There are fewer 'ums' and pauses in my spoken sentences. My reflexes are improved. I walk faster, feel lighter on my feet, spend less time analyzing and performing basic tasks and rely on my phone less for navigation. I sleep better, wake up more refreshed and alert and never feel drowsy during the day. I still drink coffee occasionally, but I no longer need it, which is nice."
Yeah, I'm the one exaggerating.
>> "Consuming only Soylent costs me about $50/month, another order of magnitude improvement, and would be cheaper if I didn't need the energy for running every day. At scale the cost would be even lower.
>>Edit: this was a miscalculation from a mistake in my spreadsheet, at personal scale it actually costs me exactly $154.82/month."
...Again. I'm exaggerating.
His blog is overly sensationalized. It really does read like a sleazy ad. He even gave his experiment a product name 'Soylent'. Sure, I was being funny about it, but I wouldn't call what I said an extreme exaggeration of what I just read.
