Excessive caffeine
Although decaffeinated coffee is an option on the coffee diet, most people prefer caffeinated coffee. Plus, many of the metabolic benefits of coffee are attributed to caffeine.

However, excessive caffeine intake can result in several health problems, such as high blood pressure (12Trusted Source).

One observational study looked at the association between coffee and blood pressure in more than 1,100 people with high blood pressure.

Those who consumed three or more cups of coffee per day had higher blood pressure readings than those who did not drink coffee (12Trusted Source).

Caffeine is also a diuretic, meaning it causes you to excrete more fluid through urine. If you drink a lot of coffee, you may need to use the restroom more frequently (13Trusted Source).

Furthermore, many important electrolytes can be lost with fluid, including potassium. Losing too much potassium can lead to a condition called hypokalemia, which can affect your muscle control and heart health. However, coffee-induced hypokalemia is rare (13Trusted Source).

Lastly, excessive caffeine intake has been linked to heart attacks, headaches, insomnia, and increased risks of bone fractures, osteoporosis, and even depression (14Trusted Source, 15Trusted Source, 16Trusted Source).

Although drinking excessive amounts of caffeinated coffee can be harmful, caffeine intake of up to 400 mg per day — or about 4 cups (960 ml) of coffee — is generally considered safe (17Trusted Source).
