In some cultures, breakfast is eaten after a period of work, in others before work begins,
others not at all. The quantities and types of food eaten as breakfast also vary enormously.
Most evidence indicates that any adverse effects on psychological or physical function due
having breakfast occurred when the person was used to having breakfast. If, after missing
breakfast, a person gets hungry later in the morning, it is likely that they will eat less
sound foods and this can lead to poor eating habits.
Some people tend to overeat in the evening. To help regulate appetite it is a useful idea to
variety of interesting, low energy-dense (low kilojoule) snacks available before and after the
evening meal to nibble on. For example, apples, celery, Swedish-style rye hard-breads
high kilojoule toppings such as butter, margarine or cheese). Exercise before or after the
meal can also help regulate appetite. Large meals in the evening may make it harder for some
people to sleep well.
Snacking is not likely to matter unless the items are sticky and therefore likely to cause tooth decay or the items are fatty and likely to cause a prolonged elevation of blood fats (see WHAT WE KNOW ABOUT FATS AND OILS IN FOOD).
