Have you ever finished lunch and before 2 p.m. your eyelids start to droop, and your stomach rumbles craving something sweet? This classic problemfor office workerscan be easily solved by switching to bringing your own "homemade lunchbox" with properly balanced nutrients to keep you full until the end of the workday without relying on bubble tea.
The secret formula recommended by the Department of Health and nutritionists is to divide the lunchbox space into four equal parts.
Eating white rice or refined starch causes blood sugar to spike and drop quickly, leading to sleepiness and faster hunger. Switch to complex carbohydrates instead.
Types of starch | Examples of ingredients | Effects on the body |
Complex carbs (Recommended) | Red rice, brown rice, sweet potato, pumpkin, beans | Slow digestion, steady energy release, long-lasting fullness, no fat accumulation. |
Simple carbs (Should reduce) | White rice, white bread, regular noodles | Digests quickly, causes rapid sugar spikes leading to afternoon drowsiness and easy snacking. |
Protein takes the longest to digest and helps maintain muscle mass. For lunch, include quality protein like skinless chicken breast, pork tenderloin, two boiled eggs, sea bass, or firm tofu. Sufficient protein intake effectively suppresses ghrelin, the hunger hormone.
Many avoid fats altogether, but healthy fats help slow digestion appropriately and improve taste. Try lightly sautéing with olive oil, adding half an avocado, or sprinkling roasted pumpkin seeds and almonds on a salad.
Pouring sauce over rice early in the morning makes the rice soggy and less appetizing. Excess sodium causes the body to retain water, leading to swelling and afternoon fatigue. Keep sauces in small separate containers and use low-sodium soy sauce, pepper, or fresh herbs instead.
