1 Sugary Cereals
They’re typically full of sugar and low in protein, meaning that they’ll rapidly increase your blood sugar levels. This can lead to irritability and hunger once the blood-sugar-reducing hormone insulin takes effect
2 Fried Foods
Fried foods can be even more unhealthy for breakfast because they are high in fat and calories, and can take longer to digest, especially when eaten first thing in the morning. This can make you feel sluggish and nauseous.
3 Fruit Juices
While fruit juice contains nutrients and antioxidants, it’s high in sugar and low in the fiber found in whole fruits, meaning it’s not particularly filling. They also raise your blood sugar levels rapidly.
4 Oily Food
Eating oily foods in the morning can cause stomach pain and discomfort if your stomach is empty.
5 Spicy food
Spicy food can be harsh on an empty stomach. Spicy foods may trigger acid reflux and irritate the lining of the stomach, leading to an unsettled stomach.
