A. Often it’s just as hard to put on weight as it is to lose weight, particularly if you come from a family with a tall slender build which you’ve no doubt inherited. On the plus side, as you get older, your skinny build will become an advantage as you’re less likely to succumb to heart troubles or diabetes, conditions which are aggravated by being overweight.

Sugar. It's been labelled "deadly", "addictive", "toxic", "sweet poison" and blamed for the rise in global obesity in recent years." Get rid of the white toxin from your diet and you'll free up your body to drop those excess kilos" (or so say anti-sugar campaigners Sarah Wilson, David Gillespie and Robert Lustig). Here are the three real reasons why I believe quitting sugar helps you lose weight.

Meeting up at the bar or pub? Sharing a drink with friends? These are the times when you notice salty snacks everywhere – potato crisps, corn chips, beer nuts, cashews, pretzels and rice cracker snacks. Salty snacks fly under the radar – no one remembers eating them. Yet they’re a big problem for health and may explain why you can’t lose weight. Here’s my take on them.

Detox diets and detox 'cleansing' kits are big sellers. They promise lots of things - to purify the body, remove 'wastes' and eliminate 'toxins' (which are never really defined) and rejuvenate the liver.

Detox has become so accepted in our time-poor, instant world that many people embark on one whenever they've overdone the excesses of life and feel the need to refresh and revitalise. After Christmas is a classic time.

The Fast Diet by Dr Michael Mosley and Mimi Spencer

I recently happened to watch dietitian Matt O’Neill comment on the new Fast Diet (aka the 5:2 Diet) on morning TV. It caught my attention not only for Matt’s usual easy-to-grasp explanation but also for the book’s simplicity and lack of a set ‘diet formula’. So when I received a copy in the post, I thought it was time for a review. 

I’ve been waiting for the launch of Go Scan for months now, having caught wind of its pending development via occasional whispers on the industry grapevine. So it was great to be invited to the official launch of this new App and get to play around with it for a review here. This is a first for Australia and one I’ll be using from now on.

A. Energy density means the ratio of kilojoules/calories you get from a given weight or volume of a food. It's really how many kilojoules/calories you can fit into a mouthful!

Most health professionals have a set against pre-sweetened kids’ cereals, as they’re generally low in fibre and only train young taste buds to prefer a bowl of ‘something sweet’ at breakfast. So when I spotted a new ready-to-drink breakfast liquid under the Coco Pops brand at the supermarket, I had to investigate.
