Jejunum: This is the section of your small intestine between your duodenum and ileum.



Kid’s Weight Training: Running and jumping has the same effect on bones as weight training and neither seem to cause premature closure of epiphyseal bone plates.



Kyphosis: This is commonly called dowager’s hump and refers to an abnormal front-to-back curvature of your mid-to-upper spine. It can be the result of compression fractures of your vertebrae.



Lachrymal Gland: This is the gland that produces tears. It is located in the upper, outer section of your eye’s orbit.



Lactase: An enzyme in your intestine that breaks down lactose.



Lactose Intolerance: The inability of your body to absorb lactose. Drinking milk products causes gastrointestinal distress.



Lactose: A sugar. It is found in milk and dairy products.



Lamina: One of the two thin, platelike parts of each of your vertebra. They join in the midline and form the base of the spinous process of that vertebra.



Laminectomy: An operation in which all of, or a portion of one or both laminae is removed. The purpose of a laminectomy is to gain access to the spinal canal, or to decompress the spinal cord and nerve roots.



Lattisimus Dorsi: The long, wide muscle of your back. When it is developed, it takes the shape of wings.

LDL: Low-Density Lipoprotein. A.K.A. bad cholesterol. A type of cholesterol that is implicated in the development of atherosclerotic plaques.

Lipase: An enzyme that is secreted by your pancreas that helps digest fats.



Lipids: A.K.A. Fats, oils, and waxes. They serve as building blocks for cells or as energy sources for the body.



Lipoprotein analysis: When you get your cholesterol tested, always ask for a lipoprotein analysis. This laboratory test determines the relative levels of HDL and LDL in your blood.



Lipoproteins: These are protein covered fat particles. They enable cholesterol and triglycerides to move easily through your blood.



Liposuction: Liposuction is the surgical removal of fat cells and their contents. It is not a pretty procedure. Try an eating and exercise program first. After all else fails, and you cannot lose your saddlebags, and you have lost fat everywhere else, and you are obsessed about pinching more than an inch, you may be a candidate for liposuction. If you undergo liposuction to remove fat from your hips, but you continue to eat with reckless abandon, your fat stores will balloon somewhere else.



Liver: Not very tasty, but it is your body’s largest internal organ. It secretes bile and is part of many metabolic functions.

Low Carbohydrate Diets: Carbohydrate-bashing diets claim that carbos are bad because they increase blood sugar and cause insulin to be released. Supposedly this is a bad thing. Proponents of these diets say insulin causes high-carbohydrate foods to be stored as fat rather than used for energy. This is just not true!



Lumbar spine: A.K.A. lower back. This is the five lower vertebrae of your spine.



Lung Problems-Training: For maximum benefits, walk or pedal at a rate that raises your heart rate to 60% to 80% of its maximum, for 30 minutes, 3 days a week. It may take days, weeks, or months to reach that goal, or you may never get there at all. But that doesn’t matter. Your goal is to improve your ability to exercise. Any improvement is great. Lung patients may make tremendous gains. In 6 weeks, you might see a 70% to 80% improvement over your initial workouts.



Lunges: Lunges are great for training your glutes and thighs.



Lupus: Systemic Lupus Erythematosus (S.L.E.) is a multi-symptom, multi-organ connective tissue disease that primarily affects women of child-bearing age. SLE tends to run in families. While no specific cause has been identified, there are thought to be many different triggers.
