12. REAL Weight loss
To lose weight you must eat less calories than you use.
THAT’S IT.
We use calories each day by just living
Basal Metabolic Rate (BMR):  the amount of energy expended daily by humans and other animals at rest. Rest is defined as existing in a neutrally temperate environment
Fit 2 fat 2 fit abc clip (4mins)

13. How many Calories do I use each day?
How to calculate your estimated BMR
(basal metabolic rate)
Men: BMR = 66 + (6.23 x (weight x 1.15))+ (12.7 x inches) - (6.8 x age)
Women: BMR = (4.35 x (weight x 1.20)) + (4.7 x inches) - (4.7 x age)
“Typical pounds” = Take your lean weight and multiply by 1.15 for men, or 1.20 for women.
*The 66 and 655 aren't typos. The BMR for women is less dependent on height and weight, which is why BMR is never less than about 1100 calories a day. Source
Example: Mrs. Coats BMR would be 1,521…. But add exercise…
Put this in your notebook

14. How exercise impacts BMR
Little to no exercise BMR x 1.2 Mrs. Coats’ would be 1,825 Light exercise (1 to 3 days per week) BMR x1.375 Mrs. Coats’ would now be 2,091 Moderate exercise (3 to 5 days per week) BMR x 1.55 Mrs. Coats’ would be 2,357 Heavy exercise (6 to 7 days per week) BMR x Mrs. Coats’ would be 2,633 Very heavy exercise (intense workouts 2x day) BMR x 1.9 Mrs. Coats’ would be 2,890

17. Metabolism is:
Metabolism = How many calories you need based on how many calories you burn by living.
The chemical reactions in the body's cells that convert fuel from food into the energy needed to do everything from moving to thinking to growing.
How many calories your body uses each day.

18. Increase Your Metabolism
Build muscle!
Muscle cells use more energy when “idle” than fat cells do, that way you are burning more calories when you aren’t exercising
Drink water!
Exercise more!
Do something fun, increase your fitness, and lose weight all at the same time

20. How to Lose Weight in a Healthy Way…
Eat Less/Eat Healthy
&

that you can maintain forever

25. The Facts
People who lose weight gradually and steadily (about 1 to 2 pounds per week) are more successful at keeping weight off.
Losing more than 2 lbs per week is unhealthy and usually temporary (water weight).
To lose weight, you must use up more calories than you take in. Since one pound equals 3,500 calories, you need to reduce your caloric intake by 500—1000 calories per day to lose about 1 to 2 pounds per week.

28. Fad Diets
The phrases food faddism and fad diet originally referred to diets and eating patterns that promote short-term weight loss, usually with no concern for long-term weight maintenance, and they enjoy temporary popularity.

29. Food Fad
"Food fad" is a term originally used to describe simple, catchy diets that often focused on a single element such as cabbage, grapefruit or cottage cheese. In 1974, the term was defined as three categories of food fads.
1. A particular food or food group is exaggerated and purported to cure specific diseases.
2. Foods are eliminated from an individual’s diet because they are viewed as harmful.
3. An emphasis is placed on eating certain foods to express a particular lifestyle.

40. Obese and Overweight; It’s not what you think

41. You may think this:

42. But what about this?

44. BMI : Body Mass Index
BMI is measured by HEIGHT and WEIGHT
BMI=kg/m2

47. Obesity
Obese = Having a BMI of greater than 30 kg/m2

48. In your journal Number 1-4

49. #1 Find your BMI

50. #2 Kevin James Height: 5’ 8” Weight: 260 lbs
* Talked on David Letterman’s late night show about times when we had weighed as much as 300 lbs

51. #3 Jennifer Aniston Height: 5’5” Weight: 110

52. #4 Usain Bolt Height: 6’ 5” Weight: 210 lbs

53. So… do you think BMI is a perfect indicator of to measure normal to obese body types?

54. BMI does not account for Body Composition
Body Composition: What your body is made of
For example:
82 lbs Lean body mass (muscle, bone, organs) 60 lbs lean body mass
+ 33 lbs Fat (body fat, cell membranes, brain) lbs Fat (body fat, cell membranes, brain)
115 lbs Total Body Weight lbs Total Body Weight

55. BMI Table LIMITATIONS It does not account for Body composition:
1.It may overestimate body fat in athletes and others who have a muscular build
2. It may underestimate body fat in older persons and others who have lost muscle mass. 7 7 7 7

56. Moral of the Story:
BMI is not a perfect indicator of health or size. Actual body composition measurements would be more accurate.
In general, BMI is good for a rough estimate of health and weight. We use it because it’s an easy measurement.
Obesity and Overweight as defined by the CDC’s BMI table, is VERY common and can look “normal.”
Insurance companies make more money insuring people who are “overweight” or obese because they are “less healthy”.
Health experts are trying to define how big too big is This is difficult because everybody is different.

Skinfold Calipers (easiest)
Waist Circumference/hip to waist ratio

88. Review What is BMI? What are the limitations of BMI measurements?
What are the limitations of body fat calculators?
What are the limitations of waist circumference?
What is the most accurate way to measure body composition? Why isn’t this more widely used?
BMI: Easiest, doesn’t distinguish between fat weight and muscle weight. Doesn’t take into regard where the weight is being stored. Weight around the waist can lead to CVD and diabetes.
Waist Circumference: indicative of health risks-doesn’t take ethnicity into account
Body fat calculator- gives general readings for body fat percentages, some need more calculations to be more accurate (age, gender, height, weight, and waist circumference). NOT THE MOST ACCURATE
-Most accurate is the BOD POD and underwater weighing.
