One sure-fire strategy to increase the amount of vegetables you're eating and reduce the total kilojoules you eat, is to fill half your dinner plate with vegetables.

By having half a plate of vegies in the evening you'll get at least three of your daily five serves of vegetable in one meal, possibly more.

Moreoever, by half-filling your plate with vegetables you're leaving less room for meat, chicken, fish, pasta, rice, potatoes - the other foods which contribute most to the kilojoules in your meal.

There's nothing wrong with eating regular portions of these carbohydrate and protein rich foods. However many people eat too many of them and too much leads to weight gain.

So fill your plate with vegies and you'll be improving your health in at least two different ways.
