It is not recommended to drink black coffee before exercising on an empty stomach. Consuming caffeine from black coffee without food may irritate the gastric mucosa, leading to excessive gastric acid secretion, which can trigger symptoms such as stomach pain, bloating, acid reflux, and nausea. In severe cases, it may cause erosion of the gastric mucosa or even directly affect systemic blood circulation. Therefore, individuals should avoid drinking black coffee on an empty stomach.

Black coffee is primarily composed of caffeine, water, small amounts of fat, and niacin, among other ingredients. Consuming black coffee while fasting may irritate the gastric mucosa, leading to excessive gastric acid secretion, which could trigger symptoms such as stomach pain, bloating, acid reflux, and nausea. In severe cases, it may even cause erosion of the gastric mucosa or adversely affect systemic blood circulation. However, black coffee does offer certain health benefits. Moderate consumption can stimulate the central nervous system, helping to increase alertness and mental focus. Additionally, the caffeine in black coffee promotes fat breakdown, effectively enhancing metabolic rate after consumption.

Before drinking black coffee, it's advisable to eat a small amount of food, such as bread, which can effectively prevent irritation to the gastric lining.
