1. Nutrition
6 classes
Macronutrients (3)
Micronutrients (2)
Water
Nonessential nutrients: is the study of how food nourishes the body.
2. Nutrients: are biochemical substances used by the body.
3. Essential nutrients: not synthezized in the body or are made in insufficient amount either obtained from
diet or supplement
6 classes
4. Macronutrients: 3: carbs, fats, proteins
supply energy and build tissue in your body
5. Micronutrients: 2 groups vitamins and minerals regulate and control your body processes
6. Water: 50-60% of total body weight, more vital to life than food, leaves the body through urine, feces, expired
air, perspiration
recommended 2200ml-300 ml/day
7. Nonessential nutrients: nutrients not required for body function or body synthesizes it in adequate
amount on its own
8. Measured in kilocalories -
Weight is stable, lost, or gained relative to amount of caloriOther factors can
affect the basal metabolic ratees consumed and energy used.: AKA calories
9. Source of calories: food you consume- carbs, protein & fat
10. Energy expenditure: Sum of all calories used to:
Perform physical activity
Maintain BMR
Digest, absorb and metabolize food
11. Weight is: stable, lost, or gained relative to amount of calories consumed and energy used.
12. Basal Metabolism: Energy required to carry on involuntary activities of the body at rest. -- the energy
needed to sustain the metabolic activities of cells and tissues
13. Male BMR: 1 cal/kg/hr
14. Female BMR: 0.9 cal/kg/hr

15. Other factors can affect the basal metabolic rate: Growth
Infection (increases)
Fever (increases BMR)
Emotions (increase BMR)
Hormones (cause it to fluctuate)
Aging (decreases)
Sleep (decreases)
Prolonged fasting (decreases)
Outside temperature (hot increases Cold decreases)
16. IBW: Ideal Body Weight
17. Females: 100 lb +/- 5 lb for each inch over or under 5 ft (Add or deduct 10% based on body frame)
18. Males: 106 lb +/- 6 lb for each inch over or under 5 ft (Add or deduct 10% based on body frame)
19. Methods to determine best body weight: BMI - Body Mass Index
Waist circumference measurement
20. BMI: very reliable indicator of the bodies fat stores, and is an indicator of heart disease, hypertension or diabetes
W (kg) / H (cm)²
21. underweight: <18.5
22. Normal: 18.5-24.9
23. overweight: 25.0-29.9
24. obesity class one: 30.0- 34.9
25. obesity class two: 35.0 - 39.9
26. extreme obesity: > 40.0
27. Waist circumference measurement: Men greater than 40 inches
Women greater than 35 inches
28. Formula to calculate % weight change: Usual body weight - current body weight / usual body
weight x 100
29. Unintentional?: sign something is wrong! Greater than 2% in a week
Greater than 5% in a month
Greater than 7.5% in 3 months
Greater than 10% in 6 months
30. Caloric requirements: 1 lb = 3500 calories
