Why is meal timing important?

The timing of your meals directly affects your body's circadian rhythm. The circadian rhythm regulates metabolism, digestion, and even mood. Eating at regular times helps your body absorb nutrients better, maintain stable blood sugar levels, and reduce the risk of diseases such as obesity, type 2 diabetes, or digestive disorders.
For example, if you eat breakfast late or skip breakfast, your body may fall into a state of low energy, leading to overeating in the evening. On the contrary, a scientific eating schedule will help you balance your energy throughout the day.
Benefits of eating on time
- Improve digestion:Eating on time helps the digestive system work smoothly, reducing the risk of bloating and indigestion.
- Energy Boost:Provides stable energy, avoiding mid-day fatigue.
- Weight control:Proper meal times help control hunger and reduce unhealthy snacking.
- Improve cardiovascular health:Eating on time helps regulate cholesterol and blood pressure.
Ideal scientific eating time during the day

Based on research from nutritionists, the ideal meal times should follow the body's circadian rhythm. Here is a sample schedule for a day:
Meal | Time | Purpose |
---|---|---|
Breakfast | 6:30 - 8:00 am | Start your metabolism, energize your day. |
Breakfast | 9:30 - 10:30 am | Maintain energy, avoid hunger before lunch. |
Lunch | 12:00 - 13:30 | Provides nutrition for afternoon activities. |
Afternoon snack | 15:30 - 16:30 | Prevent hunger, maintain concentration. |
Dinner | 18:00 - 19:30 | Support body recovery, avoid eating too late causing indigestion. |
What time should I have dinner?
Many people wonder whether they should eat dinner late or not. According to experts, dinner should be finished before 8:00 p.m. to give the body time to digest before going to bed. Eating dinner too late (after 9:00 p.m.) can put pressure on the stomach, affect sleep and increase the risk of fat accumulation.
Suggested daily scientific diet menu

- Option 2:One banana and one glass of carrot juice.
Lunch (12:00 - 13:30)

Frequently asked questions about scientific eating
1. Should you skip meals to lose weight?

If your diet is balanced, you do not need supplements. However, in case of deficiencies (such as vitamin D, omega-3), consult your doctor before use.

3. How to maintain healthy eating habits?
Start with small changes, like replacing soda with water or adding more vegetables to your meals. Make it a habit by repeating for 21 days, and find a partner to do it with.
