Food is fuel, but that fuel is only effective if one consumes it. While it's all fine and good to suggest you eat a thick piece of cauliflower instead of a steak, that suggestion is devoid of joy, and I happen to think joy is pretty important part of eating (and life). However, there are some healthy swaps out there that aren't as dismal, and I bet you all know some good ones. As always, I have some questions.

About five years ago, I came to a major crossroads in my life. While work was going OK - I'd left a lucrative but unenjoyable job because I was so desperately unhappy and decided to freelance - my physical, mental and spiritual health were smashed. And, after messing around with my teenage son during basketball training, I spent the next two weeks walking like I'd been shot in the butt, having given my hamstring a decent twang.

Something had to change. On 6 January 2013 I decided to do something about it. Here's how I became a runner.

The Great Australian Sleep Report is a national survey commissioned by Koala Mattress. It found that the majority of Aussies (60 per cent) only get 6-7 hours of sleep per night. Furthermore, around half of us aren't satisfied with the quality of our sleep and 58 per cent believe they are not getting enough of it. This infographic looks at the key findings.

About a third of adults don't get enough sleep. And sleep deprivation has serious consequences for your brain and body.

Whether you resolved to eat healthy or just have a general sense that your life needs more broccoli and fewer potato chips, these recipes will help you eat better.

Bright and beautiful fruits. Hearty whole grains. Vitamin packed vegetables in the most delicious of sauces. Are you ready for this? Here are some of our best tips, tricks, and advice on eating healthy.

Many of us have experienced the effects of sleep deprivation: feeling tired and cranky, or finding it hard to concentrate. Sleep is more important for our brains than you may realise.

Walking is free, easy and can get you from A to B - but does it “count” in terms of how much exercise we need? Let's take a look at the science.

I'm not a huge fan of overly Instagrammable foods -- I tend to prefer aggressively beige fare -- but even I have to admit that there's something extremely enticing about those colourful acai smoothie bowls that seem to be so popular with the clean-eating set.

Some days, you're full of energy, on others... not so much. Even so, if you find yourself straddling the lower end of this scale more often then not, it might be time to contemplate a few lifestyle changes. And they don't have to be that radical, as this video from AsapSCIENCE explains.

If you've had hummus or soup made with white beans, you know they have a mild flavour and blend up into a creamy texture. Take advantage of those features by blending some into your next smoothie for a fibre and protein boost.

Most people think the ideal amount of sleep is eight hours per night. As it turns out, that number is just a myth. Some people need more sleep to function optimally during the day, while others require less. Thankfully, it's possible to work out your own magic number with a little experimentation. Here's how it's done.

There are a lot of reasons to eat seaweed -- it's good for you, it's good for the environment and so on -- but I mostly eat it because I like the taste. It has a savoury, slightly funky flavour that's great in sushi, soups and salads, but I'm particularly interested in the seaweed pesto from Epicurious.

The average adult is supposed to drink around 2.5 litres of water per day. Obviously, the best method is pure H2O -- but most of us opt for coffee, fruit juice and soft drinks instead. If you'd like to be healthier but find water is too boring to enjoy, the recipes in this infographic are well worth checking out.

Topping your morning yogurt with sweet, crunchy things like granola is nothing new, but if you want a healthy, fibre-and-protein rich, substantial snack or light lunch, try topping it with grilled vegetables.

Bacon, egg and cheddar is the platonic ideal of the breakfast sandwich, but if salty pork or cheese is a little heavy for five-day-a-week consumption, consider lightening up your morning meal with a bit of fruit.

Dear Lifehacker, After doing my research and crunching the numbers, I've purchased a brand new family car -- a Subaru Forester. One factor I didn't consider is the potential toxicity of the "new car smell". I can't find any recent research in this area, but I wanted to know: Are 2016 cars still susceptible to the same problem? Will the new car harm my infant baby? Am I going into overdrive and worrying about a non-issue? Also, if new car smell is dangerous, how can I reduce or eliminate the risks?

Around a third of the population have trouble sleeping, including difficulties maintaining sleep throughout the night. While night time awakenings are distressing for most sufferers, there is some evidence from our recent past that suggests this period of wakefulness occurring between two separate sleep periods was the norm.

It's easy to pat yourself on the back for the one vegetable you ate today -- and if you normally eat zero, by all means celebrate that healthy eating victory. But singling out foods as "super" or healthy may backfire.
