According to the Australian Institute of Health and Welfare, 63% of Australian adults are overweight or obese.
But it’s much harder to estimate how many are within a healthy weight range but have poor diets or sedentary lifestyles. In short: being thin doesn’t mean you can eat unhealthy foods and get away with it.

It’s no wonder people are confused about whether it’s good to eat cheese, when even food experts are divided. Some argue that we’re not eating enough of this important source of protein and calcium, while others say the high levels of salt and saturated fat mean we should be eating less.

Carbohydrates (or 'carbs' for short) have become something of a scapegoat for Australia's rising obesity levels. Because sugar is a carb, it might seem like a good idea to eliminate all carbs from your diet. In reality, carbs contain key nutrients that the human body requires to function properly. Here are five dietitian-approved carbs that most people should definitely stick with.

Searching for the best way to lose weight? Should the emphasis be on diet, or can the solution be found in the gym? We pitched the science of one against the science of the other in a bid to find out.

Knowing what makes up a healthy diet can be really confusing. New fads and fast fixes appear weekly. At the same time, the rise of celebrity chefs and TV cooking – while admittedly entertaining – has made preparing food seem complex and often unachievable.

Fact: The more you diet, the more obsessed with food you become. So what can be done about it?

A thrusting young buck at work recently approached me to ask for some tips on toning up. He does a lot of exercise but lives pretty generously. That means, whatever his body asks him for, he generously provides. As a result he has cultivated something of a "Dadbod" and has now decided to take action to stem the tide.

Wholemeal, wholegrain, multigrain, sourdough, rye, white, high fibre white, low GI, low FODMAP, gluten free. With so many choices of bread available, how are we to know which is best for our health? Let's take a look at the science.

Meat pie? Protein. Big Mac? Protein. Meatlovers pizza? Protein. If this is you when you're on a "high protein" diet, scientists are about to kill your joy.

Like most guys of a certain vintage, I have mixed feelings about my body. Staying lean and not surrendering to the siren’s call of the dreaded 'Dadbod' is a key concern. But then so is building and maintaining enough muscle so that I can keep up with the young bucks on the soccer field or in the gym.

One of the main keys to success is your diet. You need a meal plan that's high in healthy carbs, fats and proteins. More importantly, it needs to be easy to prepare and affordable - so you'll actually stick to it.

Dear Lifehacker, I've decided I want to get healthier and shed some excess weight. I'm pretty time-poor, so I'll be mainly relying on diet microwave dinners from the supermarket (Weight Watchers, Lean Cuisine, McCain Healthy Choice, etc.) My question is: will these products actually help me lose weight? And are they considered healthy?

Most parents will tell you their kids love juice. It tastes good, often comes in convenient and child-friendly packaging, and seems much healthier than soft drinks, sports drinks or other sweet beverages. It comes from fruit, after all. But we also know it’s high in sugar, and so can contribute to obesity and dental problems.

We asked five experts in nutrition, dietetics, medicine and dentistry whether or not we should let our kids drink juice.

Many of us have lost weight to feel better about our bodies before donning a bathing suit for a beach holiday, or getting into that just-too-tight outfit for a special occasion. But old habits die hard, and before we know it we’ve started eating that chocolate cake and stopped going to the gym. Soon after losing the weight, we find ourselves back where we started – or worse. This is called yo-yoing.

It seems barely a day goes by without some new "miracle" diet littering our social media feed. Some are very well known (hello, paleo) while others are slowly gaining traction (the 'blood type' diet.) One thing that most of them share in common is a lack of rigorous scientific research. This infographic pits seven popular diets against the expertise of a professional nutritionist.

We all have that one friend whose eating habits and body shape simply don’t add up. While enjoying the unhealthiest of meals and a sedentary lifestyle, somehow they effortlessly retain a slender figure.

At first glance we may assume these slim people are healthy, but it’s not always the case. Being healthy has nothing to do with your BMI and everything to do with what you put in your mouth.

Much has been written about the exorbitant price tag of avocado toast. According to some, the swanky brekkie treat is responsible for shutting millennials out of the housing market.

Hyperbole aside, there's a good reason to give up this uber-hipster staple. They're actually not that healthy for you - especially if you're trying to lose weight.

It's that time of year again - when we are inundated with information about what the next great wellness blogger will be instagramming non-stop as a cure-all for, well, all.

So what do the experts make of this year's biggest trends - hemp, proats, flexatarianism, adaptogens, kanuka and seaweed? I spoke to nutritionist Catherine Saxelby from Foodwatch to find out.

In almost all mammals, the placenta - the organ that develops in pregnancy to provide oxygen and nutrients to the baby and remove waste products - is eaten by the mother immediately after giving birth. Humans and aquatic mammals are the only exceptions.

But the number of women choosing to eat their placenta has increased over the past decade. Here's why you should think twice before joining the placentophagy club.

A study released this month in The Lancet found a link between high carbohydrate intake and risk of death. The resulting headlines had dedicated low-carb dieters celebrating and low-fat vegans spoiling for a fight. But as with most dietary studies, there is more to it than the headlines claim.
