Eating just one serving cheeseburgers and fries is enough for the temporary effects on metabolism, as the experts found.
Eating saturated fat, which is found in unhealthy foods, causes changes in the body associated with the risk of fatty liver and diabetes. While a well-trained body can recover after one such meal, regular fast food consisting of a large amount of fatty foods, can cause permanent damage to the liver.
Experts from the German Diabetes Center in Dusseldorf tested the theory on 14 healthy young men aged 20 to 40 years old. Each volunteer received a glass of palm oil, sweetened vanilla or a glass of ordinary drinking water.
Palm oil contains the same amount of saturated fat as a whole pepperoni pizza or a cheeseburger, weighing 110 grams, which is supplied together with a portion of chips. Tests have shown that the use of palm oil results in an immediate increase in the accumulation of fat and reduce the body's sensitivity to insulin - an important hormone that regulates blood sugar.
Also, this junk food has increased triglycerides figures - fat varieties associated with heart disease. Cheeseburger worked on the liver and led to changes in the activity of genes associated with FH. Finally, the body of volunteers increased levels of glucagon - a hormone that stops the lowering of blood sugar. Note that a similar effect was observed among laboratory mice receiving palm oil.
