I still find it amazing how just a slight food deprivation helps with concentration and daily stamina. I could go through half of a night, or longer, if only I wasn’t feeding myself enough to induce blood rush to the stomach. It almost feel like not eating enough was helping me in achieving more, staying on the edge a bit longer without this overwhelming feeling of heaviness. It’s not only about forces of couch gravity, but also about state of awareness, mental agility, even in severely adverse conditions
