Document Summary

An increase in omega-3 fats = lead to a decrease in body fat. Omega-3 fatty acids can regulate gene expression: can activate a gene that regulates fat use. greater use of fat as a fuel: lipogenic. omega-3 fatty acids in the diet down regulate these enzyme y. Less formation of fat from the foods we eat. Decrease in insulin sensitivity in the adipose cells. facilitates glucose movement into cells: omega-3 intake decreases the sensitivity of fat cells to insulin but increases the sensistivity of muscle cells to insulin. promotes uptake of glucose into the muscle to be used as fuel. don t want glucose to enter the adipose cells --- omega-3 causes less glucose entry into the fat cell. Some biochemical effects of omega-3 intake yet: related to the phospholipids in the cell membranes (how they change)
