With the new 5:2 diet craze sweeping the nation -- where dieters restrict calorie intake for two days (to 500 calories for women and 600 for men) and eat what they like for the remainder of the week -- calorie counting has never been so in vogue.
But anyone who has ever tried to watch their weight will know how difficult, time consuming and just plain boring reading the backs of food packets can be.
So imagine our delight when we came across a photo project capturing 200-calorie servings on wiseGEEK.com, a website that offers clear and concise answers to common questions.
Each photograph is taken on a plate (measuring 26cm in diameter) or a bowl (measuring 16cm), to give an accurate depiction of the calorie content of each.

The project is clearly attempting to educate people to think about the calorie content in their choice of food.
"This article deals with calories only. Don't forget that there are other considerations when choosing which foods to eat, such as nutritive value and diversity of your food choices."
On the 5:2 diet women restrict their calorie intake to 500 calories for two days - that's fewer than three of the servings in the slideshow below. Could you do it?
