1000 calories, or one "food calorie"

Producing or causing the body to produce ketones.

ketogenic diet
A diet involving the restriction of carbohydrates to the point of inducing ketosis (buildup of significant levels of ketones in the bloodstream). Usually this requires keeping carbohydrate consumption below 20 grams per day.

Ketosis reduces appetite and some studies (but not all) have shown ketogenic dieters to lose relatively more fat and less lean body mass than non-ketogenic dieters. Note, however, that ketogenic diets are not usually well-suited for actually gaining muscle.

kilogram, Kg
one kilogram = 2.2 pounds

Kinesiology - Study of muscles and their movements.

Knee Wraps - Elastic strips about 3½" wide used to wrap knees for better support when performing Squats, dead lifts, etc. Bands of fabric wound tightly around the knee during powerlifting to slightly increase lifting ability; their use should be avoided during general training (apart from right before a competition) since they can obstruct blood flow, compress nerves, and grind the kneecap against the front of the knee joint, resulting in inflammation and possible damage to the cartilage of the knee joint.

knurling, knurled
a groved or roughened area along the length of a bar to increase ease of gripping or to lessen the tendency to slip (this is why a squat bar is knurled in the center whereas a deadlift bar normally is not.

Krebs cycle
a sequence of chemical reactions occuring within the mitochondria of living cells in which acetic acid (produced from foods) is oxidized to produce high-energy phosphate bonds (converting ADP to ATP ) to be used to power the body's other metabolic processes. Also known as the citric acid cycle .
