A moderate amount of coffee after intake of foods with processed sugar can effectively reduce the feeling of hunger.Clinical research indicates that moderate coffee consumption is benign or mildly beneficial as a stimulant. Coffee is rich in Caffeine, Vitamin B2, and Magnesium. Caffeine is absorbed within about 45 minutes after consuming and peaks in the blood anywhere from 15 minutes to 2 hours. It can cross into the brain. Food or food components, such as fibers, in the gut, can delay how quickly caffeine in the blood peaks. Therefore, drinking it in the morning on an empty stomach might give one a quick energy boost than when consumed while eating breakfast. Caffeine is broken down mainly in the liver. It can remain in the blood anywhere from 1.5 to 9.5 hours, depending on various factors.

A clinical trial revealed that a moderate coffee amount could effectively reduce energy intake in the following meal and the total day compared to lower or no coffee intake in overweight/obese participants. Also, thirty-three volunteers participated in the trial. They consumed a standard breakfast and 200 ml of either coffee with 3 or 6 mg caffeine/kg body weight. At fasting and at standard time points for the 3 hours following breakfast/drink consumption, participants recorded their appetite feelings on visual analog scales. At 180 min, participants consumed an ad libitum meal, and the next day they recalled their food intake during the experimental day.

Coffee or caffeine is believed to be an appetite suppressant. It is crucial to observe what effects the intake of caffeine has on the body. Consuming foods with heavy amounts of processed sugar spikes sugar levels in the body, providing instant energy while also dipping down quickly. Therefore, drinking caffeinated drinks like a cappuccino without sugar does help in reducing perceived hunger.

A Starbucks grande cappuccino has about 150 mg of caffeine in it.
