As the modern world has become more complex, our lifestyles have become more challenging, demanding, and exhausting筋疲力竭.

Food consumption消耗量 patterns模式, in pace步調 with these changes, have altered改變 remarkably明顯地 over the past few decades. For instance, we are dining進餐 outside the home more often, skipping more meals, consuming food more on-the-go總是繁忙（或活躍）, eating later in the day, and eating more irregularly不正常. In the past, dietary飲食 guidelines used to focus exclusively僅僅 on ‘what’ you should eat in terms of food and nutrients. Now the equivalent等值 amount of attention is being placed on ‘when’ you should eat over the course of a day.

Concentrating專注 on both what we eat and when we eat, although beneficial in keeping us healthy and warding off避開 chronic diseases, can be quite overwhelming難以抵擋. According to studies on the effect of meal patterns on health, eating inconsistently不一致 is likely to be associated with a higher risk of metabolic新陳代謝 syndrome併發症, such as high blood pressure, type 2 diabetes糖尿病, and obesity肥胖.

Eating irregularly may affect our internal內部 body clock which normally follows a 24-hour cycle.

For people working shifts移動或改變, their irregular dietary patterns create a greater risk of getting cancer, cardiovascular心血管 disease, and metabolic新陳代謝 syndrome併發症. In the 1960s, nutritionist Adelle Davis promoted the mantra口號, “Eat breakfast like a king, lunch like a prince and dinner like a pauper窮人.”

A good meal in the morning can give you fuel and prepare your body for the work to come.

According to Harvard School of Public Health researchers, skipping breakfast may make you hungrier and crave larger meals later in the day.

Unfortunately, this will lead to a surge in blood sugar, and increase your risk of heart disease, diabetes, and obesity.

Although calories get burned up no matter when you eat them, having a hearty meal at night can cause weight problems.

“What you don’t burn off is more likely to be stored as fat, as you become less active toward the end of the day,” said Tracy Lockwood, a registered經註冊批准的；（經政府核准） dietitian.

“Eating too close to bedtime increases your blood sugar and insulin胰島素, which causes you to have a hard time falling asleep.

Therefore, your last meal should be the lightest of the day and should be eaten at least three hours before you go to sleep.”

Having small but frequent meals to regulate appetite and control weight is a concept原則 of fad diets; yet some studies argue consuming more meals is linked to a greater risk of being overweight.

It is clear that there is no single golden rule for healthy eating for everyone.

Paying attention to when to eat, what to eat, and how many calories to consume will definitely be a good place to start.
