Persistent fatigue, lack of concentration, mid-afternoon slump... Coffee, please! What if this persistent fatigue was linked to dietary imbalances that have gradually set in over time?

In this article, TeamNutrition registered dietitians share practical tips to help you build sustainable daily energy through your diet!

1. Snacks to the rescue!

Have you ever noticed that your energy drops when you go too long without eating? Skipping a meal or spacing out mealtimes too much can lower blood sugar (glycemia), leading to fatigue, difficulty concentrating, and sugar cravings.

Incorporating a nourishing snack between meals helps reduce excessive hunger and maintain more constant concentration throughout the day. To be effective, it should combine protein and fiber to provide both energy and satiety. For example:

2. The 3 essential elements of a satisfying meal

A meal that supports energy maintenance must contain three essential elements:

  • Proteins (animal or vegetable)
  • Quality carbohydrates, ideally in the form of whole grains (brown rice, whole wheat pasta, quinoa, buckwheat, millet, potatoes, etc.)
  • Varied and colorful vegetables, which fill half the plate.

Protein and fiber slow down digestion and promote a more gradual release of energy. The combination of these 3 food groups guarantees a satisfying meal that will sustain you for several hours.

Here are a few inspirations:

3. Tryptophan: supporting your sleep

We know that daily energy largely depends on the quality of sleep. But did you know that certain nutrients play a key role in regulating the sleep-wake cycle? Tryptophan is one of them.

It is an essential amino acid used to manufacture serotonin, a neurotransmitter involved in mood, stress management, and relaxation. Serotonin is then converted into melatonin, the hormone responsible for falling asleep and restorative sleep.

The main food sources of tryptophan include:

  • Meat and poultry
  • Fish and seafood
  • Eggs
  • Dairy products
  • Whole grains (especially quinoa, oats, and buckwheat)
  • Nuts and seeds (like chia seeds, pumpkin seeds, and walnuts)
  • Soy-based products (tofu and edamame)
4. Key nutrients to support energy 

Certain vitamins and minerals play a key role in energy production and nervous system balance, sleep support, and cortisol regulation, thus influencing our daily vitality.

  • B complex vitamins: They are mainly found in fish, bananas, potatoes with skin, whole grains, and avocados.
  • Magnesium: Nuts and seeds, legumes, spinach, and dark chocolate are rich in it.
  • Zinc: It is present in legumes, pumpkin seeds, cashews, and whole-grain cereal products.

To optimize daily energy, the key is to eat a variety of foods every day and explore those that are less common in your eating habits! Get inspired with a multitude of healthy recipes from dietitians and nutritionists.

5. Hydration: the central pillar 

Hydration plays a central role in many vital functions. Water is essential for maintaining body temperature and transporting key nutrients like glucose (sugar) and oxygen to the muscles and brain.

Needs vary according to physical activity, temperature, age, and individual condition. A simple way to check if you are drinking enough is to observe the color of your urine: a pale yellow tint generally indicates good hydration.

To increase your daily water intake, always keep a bottle within reach, add a glass of water before each meal, and incorporate teas, herbal teas, and flavored waters into your routine for a change!

6. Caffeine: a real ally?

Caffeine can improve alertness in the short term, but in excess, it disrupts sleep and maintains fatigue. Relying solely on coffee often amounts to treating the symptom rather than the source of the problem. It is better to consume it in moderation and ideally earlier in the day.

Why consulting a dietitian makes a difference

Your energy is unique, your nutrition should be too! Stress, sleep, digestion, and physical activity level are all individual factors that influence your vitality.

Because when it comes to energy, there is no miracle recipe, only tailor-made solutions adapted to your body and your own pace of life!
