Many people increase their carbohydrate intake in the winter, but make sure you choose the right ones.

Avoid fast-release carbs such as bread and cereal, because they cause a sharp fall in blood glucose levels, creating cravings for sugary foods.

Instead, go for slow-release carbs with a low GI, such as wholegrains, seeds, nuts, peas and legumes. These will keep blood glucose levels even and make it easy to snack healthfully.
