Lions eat one meal every 3-4 days if I'm not mistaken. But they also sleep a lot, if not the majority of the day. I'm sure if you know what you're doing and you plan well, you can make this work. As long as you do your research on the lifestyle and are fully comfortable before committing, you should do well.
With combinations of chronic, adderall, and sleep I pretty much have been doing something similar for 2 years. Someone showed me an article about how fasting 2 days a week was extremely healthy and I was like... yeah! Thats me yo! I do rest a lot, but the time I'm up I spend productively (school, work, exercise) all the down time is party and bullshit.
