Expatriates with overseas health insurance might want to make sure they eat something every morning.
Weetabix's consultant nutritionist and dietician Sian Porter said: "Breakfast is the most important meal of the day."
It provides minerals, nutrients and vitamins that are essential for healthy and balanced diets, she continued.
The dietician noted a person's body is fasting when they are asleep, but it is also "processing, repairing and renewing itself".
It has used up all of its energy overnight and requires nourishment, Ms Porter asserted.
Furthermore, the expert argued it is even more important children have food at breakfast time because their bodies are still developing and growing.
"It is a really important habit for parents to try and instil in their children," she stated, claiming research has indicated pupils at school do not perform as well if they have not eaten in the morning.
Recent research by the firm revealed many people eat hot meals for breakfast in the colder months.
