glycerol can be converted to glucose and provide energy
Saturated fatty acids (Triglycerides) (6)
hard at room temperature commonly found in animal meats lard butter coconut oil palm oil
Unsaturated fatty acids (Triglycerides) (2)
implicated in increased HDL (good cholesterol)

Lipids Function (6)
Provide Energy (9 calories per gram)
Transport fat-soluble vitamins (A, D, E, K)
Cellular membrane structure and function
Precursors to hormones (testosterone)
Organ protection
Prolong digestive process by slowing gastric emptying
Lipid Recommendations (4)
Fat loss and overall health goals:
20%-35% of total calories from fat
20%-25% for athletes
Less than 10% from saturated fat
Dietary cholesterol
300 mg per day
Digestion of dietary fat starts…
in the mouth, moves to the stomach, and is completed in the small intestine
Dietary fats stimulate the release of..
cholecystokinin (CCK), a hormone that signals satiety. Additionally, fats slow the digestion of foods assisting in blood sugar stabilization
