Partially hydrogenated oils will not only kill you in the long term by producing diseases like multiple sclerosis and allergies that lead to arthritis, but in the meantime they will make you fat!
If you are consuming lots of saturated fats, you really have no choice but to become fat, because saturated fats contain only small quantities of the polyunsaturated fats that contain the essential fatty acids you need. The key to being thin, then, is to consume foods containing large amounts of polyunsaturated oils. (Those foods include fish, olives, nuts, and egg yolks.) Over the long term, those foods remove your sense of hunger.
Your Metabolism Slows Down
Most partially hydrogenated oil is partially hydrogenated soybean oil. Soybean oil depresses the thyroid, which lowers your energy levels.

Because a saturated fat is inert, it can’t be hurt much by heat. If you’re going to fry, fry in a fully saturated fat like coconut oil or butter, which consists mostly of short-chain saturated fats that are easily burned for fuel, plus conjugated linoleic acid (CLA) which improves health and is burned for energy instead of being stored as fat. Also, 50% of coconut oil consists of lauric acid, a medium-chain fatty acid that’s anti-bacterial, anti-viral, anti-fungus, and anti-yeast.
