Here's a silly but nerdy side-effect of 5:2 that I've been wondering about.
Recently I noticed that I seem to be getting a lot more build up of belly-button fluff than I used to. I remember getting it a lot as a younger man, but haven't had much for a while.
Reading the wikipedia article on the subject lead me to this paper on pubmed: http://www.ncbi.nlm.nih.gov/pubmed/19231087
The author concludes that the build-up of navel fluff is mostly due to hair around the navel, which is why it's something that affects men more than women. My hypothesis is that although hair may be the primary factor in causing build-up, the size of your gut may be a factor in mitigating its effects. This is perhaps due to a more curved entrance to the navel when you're fatter.
Of course my experience is just a single anecdote, so I'm wondering if any other blokes have noticed a similar effect.
Edit: Corrected a silly error where I suggested that it affects women more than men instead of the other way around.
