- Consuming most of your calories between breakfast and lunch helps you feel more energetic throughout the day.
- Eating dinner too late can interfere with sleep and hinder digestion.
- A light and balanced dinner reduces the risk of metabolic imbalances and fat accumulation.
Breakfast like a king, lunch like a prince, and dinner like a pauper. This is a well-known saying. While lunch was once truly considered the main meal of the day in many cultures, today habits are changing. Busy work schedules, shortened lunch breaks that often involve snacking in front of the computer, and daily commitments are pushing more people to eat quick meals or even skip lunch, only to compensate with a rich and abundant dinner. However, this trend might not be ideal for health: concentrating most of the calories in the evening hours can make digestion harder, alter metabolism, and disturb sleep. For this reason, it’s better to balance calorie intake throughout the day, favoring a more substantial breakfast and lunch, and opting for a lighter and more digestible dinner.
Meal size and timing also matter
For a long time, the focus was primarily on what we eat rather than when we eat. However, the timing of meals can also influence various aspects of our well-being. People who consume a larger quantity of calories in the evening appear to be at higher risk for weight gain and chronic inflammation, for example. This could be linked to our internal biological clock, which regulates metabolism and cell function.
In the morning, the body is better prepared to metabolize nutrients and distribute them to cells, providing the energy needed to face the day. However, as the day progresses, the organs responsible for metabolism, such as the liver and pancreas, become less efficient.
This effect is particularly evident in blood glucose levels: if two identical meals are eaten, one in the morning and one in the evening, the glycemic spike after the evening meal will be higher and last longer. If blood sugar remains frequently elevated due to large meals in the evening, health risks may increase.
In addition, the production of melatonin, the hormone that regulates sleep, increases in the evening hours. This process inhibits insulin secretion, making it more difficult to control blood glucose and promoting fat storage during the night.
Studies have shown that people who consume the most calories in the first part of the day tend to control hunger better and have better levels of insulin, blood sugar and cholesterol.
Healthier, fitter
Dinner need not always be the lightest meal, but it is important to avoid it being the largest meal of the day. Better distributing calorie intake helps maintain a balanced metabolism and feel more energetic throughout the day. Placing more emphasis on breakfast and lunch can promote better digestion and contribute to weight control. Dinner time also plays a key role: eating too late can interfere with sleep and alter blood sugar levels. To feel better and feel fitter, it is ideal to opt for a light and balanced dinner, avoiding overly rich meals just before bedtime.
