Obesity affects a large proportion of military police. Increased daily energy expenditure, reduced appetite and greater willingness to practice physical activity would help to reverse this scenario. Some studies suggest that acute caffeine ingestion increases energy expenditure, reduces appetite and increases mood. Thus, the objective of this study was to analyze the effect of caffeine ingestion for seven days on daily energy expenditure, food intake and perceived fatigue, disposition and appetite in obese military police officers. Fifteen police officers from the Military Police of the State of Paraná, aged 30 to 50 years, with diagnosed obesity (BMI> 30 Kg / m²), were selected. Participants ingested caffeine (5 mg.kg-1) or cellulose (placebo) daily for seven days (every day between 7 am and 9 am) using a counterbalanced, crossed and double-blind design. Dietary records and fatigue perception, disposition and appetite questionnaires were applied daily. An accelerometer was fixed in the abdominal region to measure energy expenditure during the seven days of supplementation, for at least 12 hours per day. It was found that caffeine supplementation did not influence energy expenditure, food consumption and perception of tiredness or appetite (p> 0.05). However, caffeine increased the perception of mood over the supplementation period (p = 0.02). It is concluded, therefore, that caffeine did not alter energy expenditure, perception of tiredness and appetite and the pattern of food consumption. However, caffeine seems to increase the disposition (i.e., desire to practice some physical activity). |
