If you’re fed up with trying to lose weight by drastically cutting down your food intake, then the results of a new study may be good news indeed.

For decades, health professionals have recommended cutting back at least 500 calories per day for successful weight loss but now, according to research from the US – published in the British medical journal The Lancet' s Obesity Series – shaving a mere 100 calories, or 418kJ, every day off our daily intake will result in slow but sustainable weight loss.

How? Losing weight at a slower pace means our metabolism is less likely to be affected.

"If you cut the calories in someone’s diet, the metabolism slows down and it slows down the more weight that is lost until it reaches a plateau,” says Kevin Hall, a mathematical modeller at the US National Institute of Diabetes and Kidney Diseases in Maryland.

In Australia, food energy is measured in the metric form of kilojoules, while the US still uses the imperial form of calories.

To do the sums yourself just multiply the number of calories by 4.18 to achieve the amount of kilojoules. For instance: 100 calories = 418 kilojoules .

Food swaps
