Lipase is the key player in breaking down fatty acid bonds. It starts in the mouth, where the lipase in saliva breaks down some of the short-chain lipids into diglycerides. Fat takes longer to process, so as the food moves down your digestive tract into the small intestine, the speed at which food moves through your digestive tract, also called gastric motility, sloooooows down. Bile from the liver and more lipase coming from the pancreas enter the small intestine to break the fat down into smaller chains of fatty acids, then into lipids that can be absorbed into the blood.
When digestion slows down, your gut sends the message to your brain that you can stop eating. You feel satiated, not hungry. Studies have shown that when participants ate a breakfast high in a type of fat called medium-chain triglycerides MCTs , they ate less at lunch. When they consumed more MCTs at lunch, they also ate less for dinner. Bulletproof MCT Oils are keto-friendly and help stretch out periods between meals by reducing cravings and helping you stay satiated longer.

Support science journalism. Knowledge awaits. It's an important ingredient in many tasty dishes, such as desserts and sauces, because it combines well with grains and sugars, and when it's marbled in meats, it helps make them moist and tender. Many high-calorie foods served during the holidays celebrate bounty with the liberal addition of cream and butter.
Cheesecake, eggnog , glazed ham and sweet potato pie all have high levels of fat -- after all, winter is coming, and man once needed the extra reserves. Many low-calorie food options eliminate fat as an ingredient, and because fat is high in calories -- nine calories per gram -- this seems like a practical approach. The problem is that little to no fat often means little to no flavor.
To help keep the calories down but still get a taste of the fat your body craves, try reducing the portion size of the foods you eat. The increased fat content may compensate for the smaller portion, and your body will feel fuller and more satisfied with less. To trick yourself into thinking you're eating as much as everyone else, put your portion on a smaller plate and eat slowly [source: Bobroff ]. Whatever approach you take to keep your calorie count down while still adding some flavor to your diet, keep in mind the dietary guidelines published by the Department of Health and Human Services.
Fats shouldn't constitute more than 25 to 30 percent of your total calories, and of that 25 to 30 percent, less than 10 percent should be saturated fat [Source: Bonne ]. So, even when you're dieting, isn't it nice to know that it may be a good idea to put a little oil in your salad dressing or indulge in a potato chip once in a while? You may eat only a few chips, but those fat-laden snacks may be just what you need. Food labels can help you decipher the amount of fat and other ingredients in the prepared foods you eat, and you can compare them with the recommended average daily amounts you should be consuming.
