&gt;Because it&#x27;s not that big of a deal and you already know it has health benefits?<p>Feeling hungry usually kills my concentration especially in early stages (I remember first day being the worst and later you sort of get used to it). And in general I feel weaker and drained.<p>Although sometimes when I &quot;get in the zone&quot; I actually forget about food for the entire day - usually when I need to do work and I&#x27;m not particularly motivated being hungry would make me irritable - I would probably do 1&#x2F;3 of the work I would normally do.
