What happens when you eat fatty and greasy foods:
The digestion of fat begins in the mouth where the food you chew is mixed with a small amount of lingual lipase that is found in your saliva. Lingual lipase is a digestive enzymes that breaks fatty acids apart from triglycerides.
Once you swallow your food, digestion continues in the stomach. A small amount of lipase is also secreted in the stomach to continue the digestion of fat, but most fat digestion takes place in the small intestine.
Your liver produces bile, which is stored in the gall bladder until it's triggered by eating foods that contain fat. Bile is released into the small intestine where it works like a detergent to emulsify the fats into smaller droplets. This makes it easier for pancreatic lipase to get to the triglycerides.
The bile and lipase break fats down into smaller pieces that are absorbed into the blood stream. The bile, which contains cholesterol, is either re-absorbed into the blood or bound by soluble fiber in the intestine and eliminated in the stool. Eating foods with lots of soluble fiber helps keep your cholesterol levels healthy by grabbing more of the cholesterol from the bile and eliminating it from your body.
A healthy digestive system will absorb about 95 percent of the dietary fat that you eat. People with malabsorption disorders like celic sprue, pancreatic lipase deficiency and bile salt deficiency usually can't absorb fats properly.
Fats and Oils contain nine calories per gram. Your body takes the extra fatty acids and stores them as adipose tissue, which is better known as body fat. Adipose tissue can be broken down and turned into glucose when you need more calories -- that's why counting calories is important if you want to lose weight.
How they affect you: Food high in saturated fat, like steak (certain cuts, like
rib-eye, are fattier than others), French fries, and ice cream, is difficult
for the body to digest and can make you feel uncomfortably full and increase
the chances of acid reflux, according to Palinski-Wade.
If
you already suffer from heartburn, fatty food can make it even worse by
relaxing the valve that seals off the stomach from the sphincter. The loose
valve can cause stomach acid to rise into the esophagus and result in a really
unpleasant case of heartburn, says Karen Ansel, nutritionist and dietitian.
What you can do: If you’re jonesing for a steak, burger, or other high-fat meal
tonight, remember not to combine it with alcohol, which can further irritate
your GI tract, says Palinski-Wade. Whenever possible, cook meals in plant-based
fats, such as olive oil, which is easier to break down than saturated fat, like
butter.

Both high-fat and fried food can overwhelm the
stomach, resulting in acid reflux and heartburn. "The body can only handle
so much at one time," says Jessica Anderson, RD, a diabetes educator with
the Texas A&M Health Science Center Coastal Bend Health Education Center,
in Corpus Christi.
High-fat food also can result in pale-colored stool, a phenomenon called steatorrhea, which is essentially excess fat in the feces. A lot of people with irritable bowel syndrome need to stay away from foods high in fat, she says, including butter and cream because they can cause digestive problems.
