Doctor Clarifies That Coffee Consumption Does Not Cause "Coffee Belly"

Dr. Olga Tarasova, Associate Professor in the Department of Pediatrics at the Institute of Maternal and Child Health at Pirogov University, states that coffee consumption is not connected to the development of what is commonly referred to as a "coffee belly."

She explained that caffeine inhibits adenosine receptors, which are activated when a person feels tired. This inhibition stimulates the sympathetic nervous system and prompts the adrenal glands to increase cortisol production. However, the relationship between coffee and cortisol is more complex than commonly assumed.

Dr. Tarasova noted that the hormonal response depends on the rate of coffee consumption. Individuals who drink coffee daily tend to develop a tolerance to caffeine's effects, resulting in a weaker hormonal response. Genetic factors also play a significant role, as some people metabolize caffeine quickly while others do so slowly. Additionally, the effect of drinking a cup of coffee in the morning after sufficient sleep differs from that under chronic sleep deprivation.

She added that for most healthy individuals, moderate coffee intake does not cause a chronic increase in cortisol levels.

The doctor also mentioned that coffee stimulates stomach acid secretion and increases intestinal motility, which are normal physiological responses. She confirmed that moderate coffee consumption does not significantly damage the stomach’s mucous membrane nor cause inflammation in healthy people. Furthermore, there is no scientific evidence establishing a direct link between coffee and stomach ulcers.

However, coffee may exacerbate heartburn, feelings of heaviness, and bloating in individuals suffering from gastroesophageal reflux disease, functional dyspepsia, or irritable bowel syndrome.

How Cortisol and Fat Accumulation Relate to Coffee

Dr. Tarasova explained that chronic high cortisol levels may contribute to the accumulation of visceral fat, which surrounds internal organs in the abdominal area, due to the higher presence of receptors sensitive to this hormone in that fat. Nevertheless, the key factor is the chronic nature of cortisol elevation, not the temporary increase after drinking a cup of coffee. Chronic cortisol elevation is more commonly associated with ongoing stress, insufficient sleep, and poor nutrition.

She emphasized that in most cases, an increase in waist circumference is linked to lifestyle factors rather than coffee consumption.

According to Dr. Tarasova, individuals who consume five to six cups of coffee daily, use coffee as a meal substitute, or experience chronic stress, sleep deprivation, and low physical activity should consider reviewing their habits. Conversely, most healthy adults who drink one to three cups daily need not worry about the so-called "coffee belly."

Recommendations for Coffee Consumption

Dr. Tarasova advised against using coffee as a replacement for breakfast. She also highlighted the importance of monitoring additives such as sugary syrups and cream, which often are the actual cause of increased calorie intake. She recommended avoiding coffee late in the evening and paying attention to the body's reactions; if symptoms like heartburn or anxiety occur, daily habits should be adjusted accordingly.
