Junk food can provide a quick burst of energy due to its high sugar and fat content, but this is usually followed by a rapid decline in energy levels.
This happens because the body quickly digests these simple sugars and refined carbs, leading to a spike and then a drop in blood sugar levels.
This cycle can result in feelings of fatigue, sluggishness, and irritability.
In contrast, a balanced diet with complex carbohydrates, protein, and healthy fats can provide sustained energy throughout the day.
