As anyone who has ever had a difficult day will know, stress and unhealthiness go hand in hand.
Between wine, ice cream and cheesy pizza, often people think they need something 'to make them feel better' when they're struggling - and these things work as perfect instant gratification.
One Australian author wants to change the way we see stress - in order to stop it from making us fat and change our perceptions of good and bad.
'You will never get rid of stress completely,' Luke Mathers, author of the new book, Stress Teflon, told Daily Mail Australia.
'I want to open people's mind to the possibility that stress can be a good thing. By looking at stress in a more positive light, we can start to utilise it as a way to embrace the challenges in life.'
So how can you learn to stop stress from making you put on weight, and see it in a more positive light?
According to Mr Mathers, you need to acknowledge stress for what it is, put it in perspective, and then make a choice:
'There is always a fork in the stress road,' he explained. 'One road uses the challenge response and makes stress a force for being effective and getting things done. The other fork in the road sees stress as a threat.'
'You don't have to avoid stress; you just have to re-frame it as a challenge. Knots in the stomach then become a sign that you care about something and not a cue to fight or flight.'
When it comes to your weight, Mr Mathers agrees that this is hard:
'No one has ever come home after a hard, stressful day at work and said: "I really need a controlled portion of celery sticks and fat-free hummus",' he said.
But he argues that 'booze, chocolate or double cheese nachos...don't really help with the underlying chemistry of stress'.
'Eating high calorie, comfort foods while your blood is full or cortisol and sugar will ensure that any excess energy is stored as fat,' he continued.
