12 to 48 hour reserve existed liver and in the body's muscles, quickly depleted if not replenished by daily food intake. Note, muscle and glucose make up carb reservoirs
Notes
8 to 22% body fat man more muscle mass, 20 to 35% body fat for women
Leptin
A hormone that seems to control eating behavior and fat storage
Iron

A teenage girl who has a distorted body image and refuses to maintain an acceptable bodyweight should be evaluated for
Drugs/weight-loss
Accu trim, Dexatrim, stimulating, amphetamine, and ephedra. Drugs generally work in one of the following for ways- Reducing energy intake by suppressing appetite, increasing energy expenditure by stimulating the BMR, reducing the absorption of food in the gut, altering lipogenesis and lypolosis
Voluntary energy/work and exercise
Actions related to a person's conscious activities of daily living and physical excercise
Involuntary energy/bodywork
Activities in the body that are not consciously performed, include vital processes circulation, respiration, digestion and absorption. Note, require energy in various forms such as chemical energy, in many metabolic products, electrical energy, and Braden nerve activities, mechanical energy, and muscle contraction, and thermal, heat energy to maintain body temperature
Fitness of heart and lungs
Aerobic capacity is related to
Aerobic benefits
An acceptable way to estimate the maximum heart rate is for subtract the persons age from 220, aerobic benefits, 70% of maximum heart rate for approximately 20 minutes six times per week
Fad diets
Array of diet books and weight loss supplements that promise to melt the fat away. Scientific inaccuracies and misinformation, failure to address the necessity of changing long term habits and behaviors
Notes
BMI can be tracked from childhood to adult hood with the centers for disease control and prevention growth charts
Total energy requirement
BMR/RMR, physical activities and the thermic effect of food make up a person's total energy requirements. To maintain a daily energy balance, food energy intake must match the body's energy output, energy imbalance, when energy intake exceeds energy output can lead to weight gain

BMR
Body at rest, internal activities. Note, main factors, liver brain heart and kidney
Anorexia nervosa
Body image disorder
Adipose tissue
Body source of stored energy
Kcalorie
Calorie that is used in nutrition science and study of metabolism is the large calorie, which avoids the use of large numbers and calculations, composed of 1000 calories, is the measure of heat that is necessary to raise the temperature of 1000 g, 1 L of water by 1°C
Sources of fuel
Carbohydrates primary fuel, fat assisting as a storage fuel, protein is used for energy only when other fuel sources are not available

Clinically severe or significant obesity is defined as BMI of
Chronic dieting syndrome
Cyclic pattern of weight loss by dieting followed by rapid weight gain
Behavioral modification
Designed to help change patterns that contribute to excessive weight and that can empower individuals to plan constructive actions to meet personal health goals
Hypothyroidism
Do not produce enough Thyroxine, and therefore require less energy than normal to maintain current bodyweight, opposite of hyperthyroidism
20%
During puberty, a girl begins menstruation when her body fat level reaches approximately
Growth periods
During rapid growth, Human growth hormone stimulates cell regeneration and raises BMR to support anabolic metabolism
Increase HDL decrease LDL
Effective exercise on blood lipoprotein level
Behavioral modification
Effective methods for weight reduction include
Physical exercise
Energy expenditure is increased by
Decrease with age
Energy needs per pound of body weight
Water before exercise
Establish hydration at least four hours before exercise by drinking 5 to 7 ML per KG body weight of water or sports beverage, void excess fluid before competition, and do not attempt hyperhydration
Fasting
Example of an extreme weight-loss measure
Weight management
Exercise is extremely beneficial for weight management in the following ways, it helps to regulate appetite, it increases the basal metabolic rate, it reduces the genetic factor posits that point level, and it is critical for weight-loss maintenance
Coronary heart disease
Exercise reduces the risk for heart disease in several ways including improved heart function, blood cholesterol levels, and oxygen transport
Hormonal status
Expenditure is also influenced by hormonal secretions, the thyroid function test is a means of measuring metabolism, growth hormone increases metabolism, ultimately a deficiency in normal growth hormone secretions, Linked to obesity
Influences individuals are becoming overweight
Expression of genetic factors
Scientific inaccuracies and miss information
Fad diets and supplements are often nutritionally inadequate and based on false claims.
Body temperature
Favor increases BMR by approximately 7% for each 1°F rise above normal body temperature
Increase
Fever causes the metabolic rate to
7% for each 1°F
Fever increased his basal metabolic rate approximately _____ for each _____rise
Thermic effect on food
Food stimulates the metabolism and requires extra energy for digestion, absorption, and transportation of nutrients to cells. Note, 5 to 10% of bodies total energy needs for metabolism relates to the digestion and storing of nutrients from food, involuntary
Lipectomy
Form of local fat removal a.k.a. Liposuction
Notes
Genetic predisposition for increased body fat is reinforced by inappropriate family for the patterns. Healthy eating habits during childhood and teenage years is highly encouraged to establish balanced food patterns. Women store more fat during pregnancy and after menopause in response to hormonal changes
Realistic goals
Goals must be realistic in terms of overall weight loss and weight I've lost averaging 1/2 to 1 pound per week or no more than 2 pounds per week for clinically severely obese patients
HTN, diabetes
Health problems related to obesity include
Great
If a child has a parent, the likelihood of a child also being obese is
Physical activity
In addition to increasing energy expenditure and reducing the risk of chronic disease such as heart disease, diabetes, and certain types of cancer, exercise as a positive effect on both physical and mental quality of life. Note, energy output increases during exercise
Indirect calorimetry
In clinical practice,Basil or resting energy expenditure is estimated by using
Lack of exercise/physical activity
In major contributing factor to the increase in obesity in the United States
Thermic effect of food
Increase in energy expenditure caused by activities of digestion absorption transport and storage of ingested food
Obesity
Increases the risk of related condition such as hypertension, type two diabetes, heart disease, arthritis, and certain types of cancer
My plate
Individualize calorie level and corresponding serving sizes from each of the food groups to meet nutrients and energy density needs on a basis of age, gender, weight, height, and activity level
Orlistat/Alli
Inhibiting the absorption of fat in the intestine I have to 30%, thereby reducing the caloric impact of food
Notes
Intake less than output equals weight gain, output greater than intake equals weight loss
Joule
International unit of measure for energy
Lean body mass
Largest contributor to overall metabolic rate is the relative percent of lean body mass, greater metabolic activity occurs with lean tissue, muscles and organs, as compared with that and bones
BMR factors
Lean body mass, growth periods, body temperature, and hormonal status. Note, age changes BMR, decreased per pound with age
Pregame meal
Meal should be high in carbohydrates, approximately 200 to 300 g, low in fat and fiber, and moderate and proteins, 2 to 4 hours prior to game
Notes
Men and young men require increased energy intake. During periods of rapid growth, extra energy per-unit of body weight is necessary to build new tissue. As aging process continues a gradual decline in VMR and physical activity decreases the total energy requirement. Average decline in BMR of 1% to 2% per decade, assuming that a constant weight is maintained
Heart, muscles, liver, brain, and kidneys
Metabolically active tissues in the body include
Athletic training
More susceptible to immunosuppression because of the extreme demands, a well-balanced diet with plenty of carbohydrates and protein from a variety of foods helps to prevent exercise-induced malnutrition and the risk for injury and infection
Body composition
Most important factor in determining fatness or leanness
Behavioral motivation
Most important key to successful weight loss program
Body fat calipers
Not as accurate to estimate body fat composition reliability of test depends on the skill of the technician, which can vary greatly

Thermic affect of food
The term for effective food intake on metabolic rate
Steroid/androgens
The use of androgens is of great concern, it is dangerous, and in competitive sports it is illegal
Notes
Thyroid function test may be used as an indicator of BMR, because the thyroid hormone regulates metabolism
Thyroxine/T4
Thyroid pro hormone, the active hormone form is T3, it is the major controller of basal metabolic rate
Kcalorie adjustment for necessary weight-loss
To lose 454 g which equals 1 pound per week there needs to be a 500 K CAL energy deficit per day. 1 pound of body fat equals 454 g
Energy intake
Total overall energy balance within the body depends on energy intake in relation to energy output, the main source of energy for all bodywork is food, and this is supplemented with stored energy and body tissues
External energy cycle
Ultimate source of energy is the sun and it's vast nuclear reactions, with the use of water and carbon dioxide as Raw materials, plants transform the suns radiation into stored chemical energy that is mainly carbohydrate with some fat and protein
Kcalorie
Unit of measurement used to refer to the amount of energy in food
Basil energy expenditure/BEE
Used interchangeably to describe the vast amount of physiological work. Note, must be measured when an individual is at complete digestive, physical, mental, thermal, and emotional rest
Energy
Voluntary and involuntary actions, is neither created nor destroyed
Resting metabolic rate, thermic effect of food, physical activity
What are the bodies three uses of energy estimated for energy requirement
Obesity
When energy intake exceeds energy expenditure the results can be
Internal energy cycle
When people eat plants and animal foods, the stored energy changes into body feels, glucose and fatty acids, and cycles into various other energy forms to serve body needs, these forms include the involuntary actions, chemical, electrical, mechanical and, thermal energy
Notes
Work, family, and social environments make cultivate emotional stress, which many people respond to you by eating for comfort. Fast and convenient food, an increase in portion sizes, preparation time and skills, decrease in physical activity and increasing screen time and cost are other environmental factors
8 to 22%
