Even with sufficient protein, plenty of fruits and vegetables, and a focus on healthy eating, many people still experience low energy and fatigue. This is not uncommon. Experts point out that besides sleep and life stress, hidden details in your diet can also affect your energy levels.

1. Insufficient Intake of Essential Nutrients

Energy conversion in the body requires the synergistic action of various nutrients. Focusing solely on protein and healthy fats may not be enough to support ideal energy metabolism; elements such as iron, magnesium, and vitamin B12 are particularly important. A lack of these nutrients can leave cells without fuel, leading to feelings of extreme fatigue. It is recommended to re-examine whether your diet is balanced and varied.

2. Inappropriate Food Combinations

Sometimes fruit drinks seem healthy, but they actually lack sufficient protein and fat, causing rapid fluctuations in blood sugar in a short period, followed by hunger and fatigue. Experts recommend combining fruit drinks with nuts, yogurt, and other sources of protein and healthy fats to keep blood sugar stable and avoid energy “roller coasters.”

3. Insufficient Water Intake

Even mild dehydration can cause headaches, poor concentration, and lethargy. Adequate hydration is key to maintaining cell vitality; insufficient water intake exacerbates fatigue. Developing a habit of drinking plenty of water is fundamental to boosting energy.

4. Meal Frequency and Timing Not in Line with Biological Rhythms

Everyone has a natural circadian rhythm that controls energy utilization and digestion. Meals with excessively long intervals or at inappropriate times can affect blood sugar and hormone balance, causing fatigue. Finding suitable meal times and rhythms, and avoiding large meals before bed, can promote sleep quality and daytime energy.

5. Excessive Caffeine Intake

Excessive caffeine provides a temporary boost, but it also interferes with sleep quality. Insufficient sleep, in turn, causes daytime fatigue. It is recommended to limit caffeine intake, avoiding consumption in the afternoon or evening to allow the body sufficient rest to recover energy.


Healthy eating is far more than just food selection; it also includes food combinations, meal timing, and hydration balance—all aspects of a healthy lifestyle. Understanding your body’s reactions and adjusting your lifestyle are the keys to truly getting rid of fatigue and experiencing lasting vitality.
