When you've got the muchies, it seems as though nothing but a bar of chocolate and a packet of crisps will do.  However, if you make the right choices, snacking doesn't have to mean a growing waistline. High calorie snacks can be addictive.  Chocolate, like other sweet food releases chemicals in the brain called endorphins that cause feelings of happiness and pleasure.  Carbohydrates such as cakes and biscuits also boost blood sugar levels,

and give us a burst of energy - a 'sugar fix' - when we're feeling sluggish and sleepy. However, this is soon followed by another slump, as blood sugar levels go down, and the cravings return.

In order to stop snacking unhealthily, try thinking of your snacks as mini meals. Rather than eating the standard three meals a day, try eating 5 or 6 smaller meals. This will encourage you to chose healthier, more nutritious options and keep your blood sugar levels steady.

Before you reach for the nearest bar of chocolate, take a moment to read the nutrition information on the label. Look at the figures given per 100 grams (gr) of the product, and don't chose treats with more than 10gr of sugar, more than 0.5 gr of salt, or more than 20 gr fat - the lower these numbers are the better.

Healthy snacks take a bit of planning - especially when you're out of the house. Pack a few snacks to take with you, such as a handful of unsalted nuts and raisins, a few oatcakes, or vegetable sticks with a low-fat dip.

If you're always fighting sweet cravings, try a fruit scone, fig roll or fresh or dried fruit. If you prefer savoury treats, try rice cakes with cottage cheese or hummus, half an avocado, or a slice of wholemeal toast with low fat spread.
Remember to drink plenty of water throughout the day, as you can often mistake thirst for hunger!
