I think we need to look beyond the effects to its probable causes.

Mel has obviously a very, very high metabolic rate and therefore needs more food that someone who has a low or ordinary metabolic rate.

Food deprivation - like sleep deprivation - can cause the sufferer to be unusually irritable and tetchy.

Mel was the only woman - being on the men's team - to go without proper sustenance for 4 days.

Marital breakdown wounds the most ordinary of us in private, and makes us feel like we have personally failed, so for such a famous, beautiful and successful celebrity to have to deal with her marital failure in the 'public eye', must be deeply humiliating - no matter how much of a 'brave face' she may put on. So Mel being already emotionally 'disturbed' due to her marital and personal problems prior to entering the jungle, probably meant that she was unconsciously in 'defensive' mode about any question or subject to do with 'relationships'. Hence why she may have overreacted with Edwina - who does seem to like pushing younger, more attractive female's 'buttons'.

Finally who knows whether - on top of all this - Mel wasn't also suffering PMT, MT or Post MT? I mean she's hardly likely to advertise the fact is she?
