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.

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

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

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
