The Right Way to Lose Weight After 40

Fat makes you fat. No, wait, carbs are the enemy. The truth is, when it comes to losing weight, it's all about kilojoules: you have to burn off more than you take in. But over the years, that message has been lost, which may partially explain our increased kilojoule consumption. From 1983 to 1995, the average daily energy intake of Aussie women rose by 5 per cent, from 6,983 kJ to 7,341 kJ, and today's estimates put that figure at about 7,850 kJ. Surveys also reveal that only about 11 per cent of Australian women exercise intensively and fewer than half of these do it regularly. This means few of us burn enough kilojoules to warrant the amount of food we eat. (For every kilogram of your body weight, you burn from 80 to 130 kJ daily—80 kJ if you're inactive, but as many as 130 kJ if you exercise for 30 to 60 minutes on most days.) When you're guessing how much you can eat, being off by just a few hundred kilojoules a day can keep you 2.5 to 4.5 kg overweight. Experts say this is why the average woman in Oz is reportedly more than 5 kg heavier now than she was in 1990—and why getting the kilojoule count right for your body and lifestyle is the only way to reach your ideal weight. Our guide shows you how.
