According to animal studies conducted at the University of Wisconsin, consuming a diet high in Omega-3 fatty acids is a sure way to increase your metabolism and energy levels.
Scientists monitored the diets of lab mice and found that rodents who consumed greater amounts of omega-3’s had a higher metabolism due to lower levels of a hormone, known as leptin. Researchers noted in their findings that omega-3’s naturally help lower leptin, which in turn, leads to naturally faster metabolism.
