Many people have a habit to skip breakfast. Some are trying to reduce the calorie intake, others have no appetite in the morning, while some simple are too busy. However, skipping breakfast has a negative consequences for the organism.

A large number of studies have shown that breakfast has a beneficial effect on health. Skipping breakfast can have an adverse impact. Here’s how:

Increased level of cholesterol – apparently, there is a relationship between elevated levels of cortisol (stress) and high levels of bad cholesterol. Skipping breakfast, indirectly through raising the level of cortisol, can lead to a high level of bad (LDL) cholesterol.


The level of “stress hormone” increases – cortisol is called the “stress hormone”. The level of cortisol in the body is the highest around 7 in the morning. Consuming breakfast decreases the level of cortisol. So by skipping breakfast your cortisol levels remains the same until the first meal. Having high levels of cortisol in the body a long time can lead to nervousness, anxiety and increased blood pressure.

Increased risk of type 2 diabetes – one study found that skipping breakfast is associated with type 2 diabetes. Elevated levels of cortisol (which is associated with skipping breakfast) leads to two things: first, increased secretion of insulin, and second increased secretion of glycogen which is decomposed to sugars. Raised levels of insulin for a longer period of time can cause cells to be resistant to insulin, which over time can lead to the development of type 2 diabetes.


Risk for heart diseases can be increased – a study conducted at Harvard University found that men who skip breakfast have a 27% higher risk of heart attack or death from cardiovascular disease compared to those who eat breakfast. Although scientists are not able to say exactly what caused it, the assumption is that the longer you are hungry the bigger are chances for metabolic changes, which can lead to heart disease.

Conclusion: the habit of skipping breakfast every day for many years exposes the body to unnecessary chronic stress. Stress, on the other hand, can lead to a series of negative influences like high blood pressure, atherosclerosis, type 2 diabetes and heart problems. So, in short: you shouldn’t skip breakfast.
