Caffeine does not suppress appetite nor does it help to lose weight

MEXICO CITY, July 24 – A new study published in the journal Academy of Nutrition and Dietetics The United States has shown that although drinking a small amount of caffeine at breakfast helps reduce food intake at the first meal of the day, its effect is limited and transient, so the experts do not approve it. as an appetite suppressant or helps to lose weight.

The authors of this research found that after drinking a small amount of caffeine, participants consumed 10% less in a breakfast buffet provided by the researchers, but this effect did not occur. persisted all day and had no impact on participants' perceptions of their appetites. Thus, they consider that caffeine is not effective as an appetite suppressant or helps to lose weight.

"Caffeine is often added to dietary supplements with claims that it suppresses appetite and facilitates weight loss." Previous research has speculated that caffeine speeds up metabolism or affects brain chemicals that suppress appetite and evidence. Epidemiology suggests that regular users of caffeine have lower body mass, "Leah explains. Dr. Panek-Shirley, Principal Investigator, Department of Exercise and Nutrition Sciences, University of Buffalo, New York. was to determine whether caffeine may be related to reduced food consumption or a lack of appetite, and whether the results vary according to BMI. "

On average, Americans drink 8 ounces of coffee a day (about 0.23 liters). 50 healthy adults (between 18 and 50 years old) visited the researchers' laboratory each week for a month to participate in the study.

Each time they were asked to drink juice with added caffeine equivalent to four ounces (1 mg / kg) or eight ounces (3 mg / kg) of coffee, or no coffee as a placebo. 30 minutes later, participants were invited to eat as much or as little as they wanted from a hearty buffet breakfast.

The study determined that after drinking the juice with 1 kg / mg caffeine, participants consumed about 70 fewer calories than they consumed after drinking juice with 3 mg / kg or without added caffeine.

After reviewing what participants ate during the rest of each study day, they found that the small decrease in intake did not persist. In fact, participants made up for the reduced intake at breakfast later in the day. In addition, there was no difference in reported appetite associated with caffeine doses. Finally, your individual BMI had no effect on your consumption or appetite at all three caffeine levels.

"This study, because of its rigorous design, reinforces the importance of good eating habits and does not depend on help for weight loss or unhealthy practices," explained Carol DeNysschen, one of the researchers, professor and chair of the Department of Health, Nutrition and Dietetics, SUNY Buffalo State College.
