      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Basic scienece, Randomization description: They will be randomly divided into one of two groups of intervention and placebo and will be studied for 12 weeks. The intervention group will receive a daily capsule containing curcumin piperine (containing 500 mg of curcumin extract and 5 mg of piperine) and the control group will receive a daily placebo capsule (500 mg of maltodextrin) with diet and exercise recommendations; The recommendations are the same in both groups, Blinding description: In order to conduct this research in a double-blind manner, before starting the study, the total capsules are coded in A and B by a person other than the researcher, so that both groups do not know the type of capsules received by both groups. To track that individuals in the study groups use the capsules.</study_design>
