Resumo
The progressive increase in obesity shows the importance of changing strategies to combat this disease in order to reduce weight and maintain this reduction. Among the main treatments for obesity, there is a change in eating habits and physical exercise, an alternative strategy. Placebo supplementation has been used as an auxiliary strategy in several clinical conditions, including the treatment of obesity, in recent years. However, results from a placebo study are controversial. Considering that placebo studies on obesity are scarce, this study aimed to assess whether the use of placebo is an effective auxiliary strategy in the treatment of obesity with diet and exercise in young women. This study is a randomized clinical trial with 28 women allocated in three groups in relation to the expectation of treatment with supplement: 100%, 50% and 0% of expectation in taking supplement that would increase the metabolism. All volunteers underwent high-intensity interval training for 8 weeks (3 times a week) and received nutritional guidelines for changing eating habits. The results show that there was an increase in VO2max at the end of the intervention in relation to the baseline in the groups. 100% (p = 0.021) and 0% (p = 0.035), intragroup evaluation. The evaluated variables had no changes in the comparison between the three groups. It was possible to notice that the absence of side effects in relation to supplementation meant that they had no belief in the supplement. It is concluded that supplementation with placebo did not influence the reduction of weight and fat mass of young and obese adult women.
