Do you start the day with energy? Or tired? 🤔 - Let's think about your diet!
Table of Contents ▾

Sunethra (age 38) came to my clinic last Tuesday morning feeling extremely tired and lethargic. She is a school teacher.

"Dr. Priya, even though I sleep for 8 hours at night, I wake up in the morning with no energy. I feel incredibly tired. I usually eat something like jam or a bun with bread in the morning and drink a cup of tea with 3 spoons of sugar. But by 12 noon, my body is completely exhausted," Sunethra presented her problem.

I calmly explained to her, "Sunethra, your problem lies in your breakfast diet. The refined carbs you eat in the morning, like sugar and white bread, cause your blood sugar levels to spike and then drop again quickly (Sugar Crash). This is the main reason you feel tired in the morning. Our body is like a super machine. It needs to be fueled with the best nutritional fuel at the beginning of the day. Today, let's talk about how to create a balanced diet that will help you stay strong throughout the day."

🚨 Red Flags that require immediate medical attention

Although constant fatigue and lack of energy may be due to a normal diet, if you experience the following symptoms, you should seek immediate medical attention as they could be signs of a more serious condition (e.g., anemia, thyroid problems, or diabetes):

  • Chronic fatigue (severe fatigue) that persists for several weeks despite adequate rest and sleep.
  • Unusually rapid loss of body weight without effort.
  • Swelling in the front of the neck (Goitre) or inability to tolerate extreme cold/heat.
  • Frequent feeling of excessive thirst, frequent urination, and blurred vision.
  • Severe shortness of breath and chest tightness even when doing minor tasks.

3 harmful foods that are harming our body

Many people, hoping to save time in the morning, are accustomed to consuming the following foods that are extremely harmful to the body:

1. Processed Food: Sausages, packaged foods, and bakery products contain harmful artificial flavors and preservatives, and their nutritional value is minimal.
2. Sugary Drinks: Artificial fruit juices, carbonated drinks, and sugary tea/coffee can lead to weight gain and an increased risk of diabetes.
3. Trans Fats: Trans fats found in deep-fried fast food can clog blood vessels and cause heart attacks.

How to prepare breakfast to stay energized throughout the day

A balanced diet is a diet that contains the following nutrients in the correct proportions:

  • Carbohydrates - 45-65%):Gives the body energy for daily work. Instead of white rice and white bread, choose complex carbohydrates such as bran brown rice, buckwheat, and oats.
  • Protein (Proteins - 10-35%): Essential for muscle growth and immunity. Include eggs, fish, lentils, chickpeas, or green beans in your breakfast.
  • Healthy fats - 20-35%): Helps with brain function and hormone production. Good fats can be obtained from foods like avocado, olive oil, sesame seeds, and peanuts.
  • Fiber, Vitamins, and Minerals: Fresh fruits and green vegetables help the body's metabolism function properly.

Key components of a balanced daily diet (NHS guidance)

Food category Recommended daily use Major health benefits
Fruits and vegetables At least 5 portions a day (5-a-day) Rich in vitamin C, potassium, and antioxidants, it protects against disease.
Bran grains About 1/3 of the total meal It is rich in fiber, which protects the intestines; releases energy slowly throughout the day.
Milk and milk products In limited quantities (low fat) It strengthens bones because it is rich in calcium and vitamin D.
Clean water 2.5 - 3 liters per day (8-10 glasses) Prevents dehydration and regulates brain function and body temperature.

Do's & Don'ts

✔️ Things to do ❌ Don'ts
Drink a glass of clean water as soon as you wake up in the morning to refresh your body. Don't drink artificial energy drinks to stay energized throughout the day.
Plan and prepare the vegetables and grains you need for the entire week in advance on the weekend (Meal Prep). Never skip breakfast. It is the most important factor that affects your day's activity.
If you drink tea or coffee, take it at least an hour after a main meal (to avoid interfering with iron absorption).Avoid eating oily, spicy, or large meals at night. This can cause severe discomfort and lethargy the next morning.
❓ FAQ

FAQ

Evidence-based clinical answers to common patient questions

Why is white bread not suitable for breakfast?

White bread is a simple starch that has had its fiber removed. It is quickly absorbed by the body and raises blood sugar levels rapidly, only to fall again quickly within a few hours. This can lead to feelings of extreme fatigue and hunger during the day.

What are the best types of protein for vegetarians to have for breakfast?

Vegetarians can obtain highly nutritious protein from legumes such as chickpeas, mung beans, peas, and lentils, as well as nuts such as soy, tofu, and peanuts.

Can dehydration cause a decrease in energy?

Yes, dehydration occurs when our body's water level drops even by 1-2%, which reduces blood volume and limits the amount of oxygen reaching the brain. This directly affects severe headaches, fatigue, and decreased mental focus.

Can drinking coffee provide a constant daily boost of energy?

Although the caffeine in coffee temporarily wakes up the brain, excessive consumption can disrupt sleep and deplete the body's natural energy in the long run. It is best to limit coffee to just 1-2 cups a day.
