Proper fuelling of the brain is important for maintaining our mood too. For some people, low blood sugar can cause people to experience ‘glass half empty’ syndrome. I remember a banking executive who told me he always knew when his blood sugar level was on the slide as he would inexplicably start seeing the world through ‘shit-tinted spectacles’. At least he had a sense of humour about it.

In others, low blood sugar can wind them up like a top. This is partly because it has the ability to activate the body’s stress response and cause surges in hormones such as adrenaline and cortisol that can bring on feelings of anxiety or aggression. Low blood sugar also ramps up the production of a chemical known as ‘glutamate’ in the brain, which can increase our sense of agitation and irritability.

A common danger time for these issues is the end of the day, when someone may return home in a too-hungry state. The chemical imbalances induced here can cause the most insignificant things – be it some apparent untidiness or an ambiguous comment – to trigger a mini-meltdown. If you want to know the simple measure you can take to stop yourself making a right nuisance of yourself when you walk through the door (and perhaps save your relationship, too), read Chapter 3.
