During breakfast time, your body needs something that gives you energy and satisfies your appetite for longer periods until the next meal. But there are certain foods that can’t give healthy benefits and drain your body's resources.
Ask yourself these few questions:
➤ Do you feel tired after eating a meal within thirty minutes?
➤ Do you feel uncomfortable or dizzy after eating some snack?
➤ Do you feel uneasiness after drinking energy-boosting drinks?
If you can relate to any of these experiences, certain food choices may have increased your blood sugar levels, and that makes you feel tired even after fulfilling your hunger needs.
Let’s understand more about this concept by firstly understanding the timing of the day when you feel low energy and the type of food you consumed before having such an experience is an important factor in identifying such food habits.

Foods that crash or drain your energy do not need to be avoided entirely from your diet. Adding some healthy alternatives, such as consuming protein in the form of eggs, paneer, or dal and having fruits and nuts during breakfast, can be beneficial. It is also important to keep oneself hydrated, as most of the time hunger can be confused with thirst.
