Sweet or savoury - we all have cravings.
But rather than indulge in a salty bag of potato crisps or your favourite chocolate, experts say our cravings are the body's way of telling us we are lacking nutrients.
Australian nutritionist Amelia Phillips has explained what our desires for certain foods mean - and what cravings say about your health?
She explains there are two types of cravings - psychological cravings and physiological cravings.
"So you want to differentiate - is it a craving that's happening in your head or is it more of a craving that's coming from down here [stomach]," she says.
Phillips said if you're experiencing intense cravings - it would take just two weeks to break the habit to start fresh on your diet.
"If you do find there is a particular craving like the chips at 3 o'clock or the chocolate after dinner, break that habit by getting busy," she says.
Phillips says simply doing household chores or exercise could help shift your focus away from cravings.
"You'd be amazed at how quickly you can change your habit around," she adds.
"But if you notice the cravings come unusually, like you never crave salty things and then all of a sudden you crave salty things - that could be a sign you have a deficiency."
Craving something salty
Craving salty foods could be a sign of mineral or electrolytes imbalance.
Phillips explained the calcium and magnesium levels in the body are too low.
She says if you're physiologically craving salty foods as - it could be a sign of a mineral/electrolytes imbalance or a calcium/magnesium deficiency.
"If you've been used to having the salty chips everyday, it's a habitual habit."
"The thing with salt is, the more you have, the more you need to satisfy the cravings. So you need to back off on the salt."
She says popcorn is a good alternative - but if you preferred a healthier option, she advised eating cottage cheese and tomatoes drizzled with balsamic vinegar.
Craving something sweet
"If it's the physiological craving, then it could be a sign of blood sugar deficiency, poor habit or your body requires a balanced palate," Phillips said.
"It's the same as salt, the more you have the more of it you need to satisfy your cravings so you need to break that cycle and change the time of day you're having it."
She said healthy alternatives include fruits, Greek yoghurt and pumpkin puree.

Craving carbohydrates
"The body breaks [carbs] down the glucose so it's similar to the sugar cravings. A little bit goes a long way with carbohydrates," she explained.
"So try and reduce your portion sizes down, stick to wholemeal pasta, always add fibre and protein - and that stops that blood sugar spiking, which is what creates these cravings and imbalances in the first place."
