1. Lowers appetite
Eating junk foods will deprive your body of essential nutrients and kill your appetite by keeping your stomach full for a long period of time. Excess consumption of processed and fried foods can send mixed signals to the brain, which makes it difficult to process how hungry you are and how much satisfied. This lowers your consumption of healthy foods.
2. Causes memory problems
Recent research suggests that bad fats (trans fats) from junk food tends to replace healthy fats in the brain and interferes with its normal signaling mechanism. Higher intake of high fat and high sugar foods can slow down the speed of learning, memory and attention. Excessive consumption of foods high in fat and sugar changes the parts of the brain that are responsible for learning, memory and reward.
3. May cause depression
A study found that people who eat fast foods and processed foods are at an increased risk of depression compared to those who consume less fast foods.
People who eat fast food and processed pastries are 51 percent more likely to develop depression than people who don’t eat those foods or eat very few of them.
4. Impairs digestion
Junk food can cause digestive problems like gastroesophageal reflux disease (GERD) and irritable bowel syndrome (IBS). They also cause other digestive problems such as acidity, constipation and bloating.

Junk food is high in refined sugar. Refined sugar causes the pancreas to secrete more amount of insulin in order to prevent a drastic spike in your blood sugar levels.
8. Causes liver damage
Higher intake of fast foods is highly toxic to the liver because these foods are high in fat and sugar. High levels of trans fats found in a number of junk food can cause deposition of fats in the liver, which can cause liver dysfunction. Also a high amount of bad fats and sodium from salt increases blood pressure and affects kidney function.
