30-Days of High Omega-6 Diet--Stiffens Arteries and Increases Belly Fat

Someone followed a high-ish Omega-6 diet for 30 days and tracked the changes in her body. 

Results: The results were surprising for only a 30-day evaluation.  Susan’s weight remained unchanged. But there were dramatic changes in her blood fatty acid composition, body fat, arterial function, and body mass composition. During the 30-day period, omega-6 fatty acid was significantly increased, while omega-3 fatty acid content was decreased.
... While body weight remained the same, body fat increased in the abdominal area by nearly ½-pound.  Fat was also increased in the trunk region, where notably, lean body mass decreased.  Metabolic rate also decreased from 1367 to 1291 calories.
In just 30 days, brachial artery dilation dropped by 22%, a change much larger than the day-to-day variation of this test. The amplitude of this changed surprised everyone involved in this project.  Susan’s arteries were also stiffer, as revealed by the ultrasound scan, which indicates blood vessels are less able to expand and contract.
