Study Notes
Understanding Body Weight and Weight Management
- Healthy body fat percentages for males and females vary: 13-21% for men and 23-31% for women.
- Waist circumference can assess android obesity, indicating extra fat in the abdominal area, which increases disease risk.
- Males are more likely to have an "apple" shape (central obesity) while females are more likely to have a "pear" shape (lower body obesity).
- Energy balance dictates that if energy intake equals energy expenditure, a person should maintain their body weight.
- The four components of energy output are basal metabolism, physical activity, thermic effect of food, and non-exercise activity thermogenesis.
- Basal metabolic rate (BMR) is the minimum energy the body uses for vital activities at complete rest.
- Factors increasing BMR include growth, very low-calorie diets, exercise, and stimulant drugs, while aging and insufficient thyroid hormone decrease BMR.
- BMR can be calculated using specific formulas based on gender and body weight.
- Factors influencing energy expenditure during physical activity include the type, duration, intensity, and the person's weight.
- The thermic effect of food contributes to 5-10% of total energy output and refers to the energy required to digest, absorb, and metabolize nutrients.
- NEAT (non-exercise activity thermogenesis) includes involuntary skeletal muscle activities like fidgeting, shivering, and body posture.
- Factors influencing body weight include internal factors (genes, hormones), individual factors (food, psychology, exercise, stress), community factors (supports, beliefs), local factors (food economy, health systems), and global factors (chemical waste, global food economy).
Vitamins and Minerals: Functions and Deficiencies
- Key vitamins in energy metabolism: Niacin, Pantothenic acid, Vitamin B-6
- Deficiencies and symptoms: Scurvy (Vitamin C), Beriberi (Thiamin), Pellagra (Niacin), Neural tube defects (Folate), Megaloblastic anemia (Folate, B-12), Pernicious anemia (B-12), nerve damage (B-12)
- Classic signs of ariboflavinosis: Glossitis, Cheilosis, Skin rash, Confusion, headaches
- High doses of niacin: Used for treating high cholesterol, potential toxicity concerns include flushing of skin, GI upset
- Functions of folate: Coenzyme THFA, DNA synthesis, Homocysteine metabolism
- Healthcare facilities testing for blood homocysteine levels: Checks for B-12 or folate deficiency
- Food sources of folate: Papaya, beef liver, Broccoli, Asparagus, grains
- Folate intake for women of childbearing potential: 400 mug/day
- Concerns with excessive folate intake: May stimulate cancer cell growth, "masks" vitamin B-12 deficiency
- Importance of vitamin B-12: Coenzymes for cellular processes, folate and homocysteine metabolism, maintenance of myelin sheaths
- B-12 absorption and levels: Requires intrinsic factors secreted in the stomach, levels decrease with age
- Populations at risk for B-12 deficiency: Vegans, Elderly, Gastritis, leading to megaloblastic anemia, pernicious anemia, nerve damage
