Slide 1-

BASAL METABOLIC RATE Presented by, Ajith K K Asst. Prof Nursing college kishtwar
Slide 2-

Energy Energy is the capacity to do work. We need energy for : Basal Metabolism Basal Metabolic Rate- BMR: energy required for activity of the internal organs and maintaining of body temperature. Physical Activity Metabolizing of Food
Slide 3-

Calorie: unit used to measure energy Kilocalorie is a unit of energy commonly used to express energy value of food. Food energy is the amount of energy in food that is a available through digestion. The energy value of food indicates its value to the body as fuel.
Slide 4-

Kilocalories come from foods and beverages Bomb calorimeter used in laboratories to measure kilocalories in foods and beverages Results must be adjusted for the physiological fuel values Nutrition analysis software or food composition tables can estimate energy in Carbohydrate and Protein: 4 kcal/gram Fat: 9 kcal/gram Alcohol: 7 kcal/gram
Slide 5-

What Is Energy Balance and Why Is It Important? Energy balance is achieved when the kilocalories consumed equal the kilocalories expended
Slide 6-

The Concept of Energy Balance
Slide 7-

The Basal Metabolic Rate Keeping your Basal Metabolic Rate (BMR) as high as possible is vital when it comes to weight loss and maintaining healthy body fat levels
Slide 8-

Factors that Affect Basal Metabolic Rate Exercise: This is one of the biggest factors that influence BMR. BMR is higher in people who exercise regularly
Slide 9-

Hormones: an increase in thyroid hormones increases BMR, decreased levels of the hormone lower BMR Body Temperature: Excessive heat or cold raise BMR
Slide 10-

Gender: Males tend to have higher basal metabolism than females due to an abundance of hormones such as testosterone ad elevated levels of muscle mass compared to females Age: as we get older basal metabolic rate becomes increasingly slower.
Slide 11-

Surface Area: Taller individuals have a higher BMR compared to shorter individuals. More surface area means more heat lost from the body, which causes the metabolism to speed up in order to maintain body temperature.
Slide 12-

Stress and Illness: increase in hormone activity due to physical or physiological stress increase BMR. Starvation: Fasting for more than 48 hrs. will lead to a decrease of 50% of Basal Metabolic Rate.

Health Risks Associated with Body Weight and Body Composition Being overweight increases health risks Overweight and obesity associated with increased risk of heart disease, hypertension, stroke, hyperlipidemia, gallstones, sleep apnea, and reproductive problems Increases risk of certain cancers including colon, breast, endometrial, and gallbladder cancer More than 80% of people with type 2 diabetes are overweight Metabolic syndrome is associated with central obesity
Slide 15-

Health Risks Associated with Body Weight and Body Composition Being underweight also increases health risks Symptomatic of malnutrition, substance abuse, or disease Higher risk of anemia, osteoporosis and bone fractures, heart irregularities, and amenorrhea Correlated with depression and anxiety, inability to fight infection, trouble regulating body temperature, decreased muscle strength, and risk of premature death May be unintentional and due to malabsorption associated with diseases such as cancer, inflammatory bowel disease, or celiac disease
