The Effect of ω3 Fatty Acids Supplementation on Levels of PPARγ and UCP2 Genes Expression, Serum Level of UCP2 Protein, Metabolic Status, and Appetite in Elite male Athletes: Protocol for a Randomized Control Trial.

Omega3 fatty acids as a ligand of metabolic-related genes, have a role in energy expenditure.Omega3 supplements effect on PPARγ and UCP2 mRNA expression as regulators of energy metabolismOmega3 supplements increased REE.Omega-3 supplementation could change the changes in body composition.For athletes, omega-3 simultaneously decreased fat mass and increased fat-mass.HDL-C increased after short-term supplementation with omega-3.Increased intake of omega-3, caused increased intake of energy and protein.
