No, you’re not imagining it: feeling ‘hangry’ – or hungry-angry – is a real thing. This is because, unlike other organs, your brain relies on a drip-drip-drip supply of glucose throughout the day to stay properly fuelled so, if you don’t eat regularly or you skip meals, you won’t feel your best. As well as eating regularly, drop your fear of fat. The brain is made up around 50 per cent fat, and our cells need good quality fats to maintain their structure so consider good fats those found in olive oil, nuts, seeds, and avocados.
