Eating fast food on a regular basis is linked to negative effects on skin, bones, digestion, the respiratory system and the central nervous system, according to Healthline. Fast foods are typically carbohydrate-dense, contain excess calories and digest as sugar, or glucose, in the body. Frequent spikes in glucose levels from eating too many carbohydrates cause abnormal insulin levels, which lead to insulin resistance and type 2 diabetes.

Many people don't realize how many calories they're consuming when they eat fast food, and studies show that most people eat more calories at restaurants than at home, states Healthline. Over time, the extra calories cause weight gain and obesity, which are linked to a variety of chronic illness conditions. Obesity causes respiratory problems such as shortness of breath, wheezing, asthma and sleep apnea.

Other correlations between eating fast food and health conditions include skin problems such as acne and eczema, notes Healthline. Additionally, mouth bacteria produce acids from carbohydrates and sugar that destroys tooth enamel and leads to decay. Excess sodium leads to osteoporosis, and eating a lot of fast food takes a toll on the central nervous system, which can contribute to depression.
