Calories
  • Calories or “kilocalories” are simply a unit to measure energy in food that your body burns.
  • Sources of calories
    • Carbohydrates: 4 calories per gram
    • Protein: 4 calories per gram
    • Fat: 9 calories per gram
burning calories
Burning Calories
  • Several factors play a role in the number of calories each person requires to maintain a healthy body weight.
  • Examples are age, sex, height, body build, and metabolism.
  • One of the most important factors is the persons daily activity level.
  • Active individuals need more calories than sedentary ones.
energy balance
Energy Balance
  • Think of food as fuel.If you are eating more calories than you are using than the body will store the extra as fat.
  • Each pound of body fat
  • equals 3,500 calories.
body fat vs body weight
Body Fat vs. Body Weight
  • Overweight:Weighting more than 10 percent over the standard weight for height.
  • Obesity:Excessive body fat, or adipose tissue.
  • Not all overweight individuals are unhealthy, excess muscle mass may be categorized as overweight. Body composition is a better indicator of fitness and health.

  • Heredity may be a contributor to obesity but the exact relationship is not clear.
health risks of being under weight
Health Risks of Being Under Weight
  • Underweight:10 percent or more below normal weight.

  • Eat nutrient rich snacks, but space them out, at least two to three hours before meals to avoid spooling your apatite.
exercise
Exercise
  • A healthy diet and regular exercise go hand-in-hand. SAFE weight loss can not be achieved from just one.
  • Exercise with friends and you will forget you are exercising. Just get up and move!
  • Regular exercise can burn calories, tones and builds muscle, relives stress, increases metabolism, and increases self-esteem.
fad diets
Fad Diets
  • Your “Diet” is what ever you eat.
  • To loss weight and be healthy, you must follow life-long health eating habits.
  • If the “Diet” is not something you can see your self following for the rest of your life, it is a “Fad Diet” and will inevitably lead to a rebound back to old eating habits and weight gain.
  • Examples are “grapefruit diet” and “cabbage soup diet”.

Fad Diet
  • The bottom line is:

if it seems “to-good-to-be-true”, it probably is.

fad diet17
Fad Diet
  • Something all fad diets have in common is the fact that they drastically limit the food options a person has which reduce the calories consumed, resulting in the weight loss.
  • So, when the person inevitably goes back to their “pre-diet” eating habits, they regain the weight (and then some)!
weight cycling
Weight Cycling
  • Repeatedly loosing and regaining weight. Also known as “yo-yo dieting”.
  • The body has learned to work more economically, using few calories so the excess will be stored as fat in the place of the lean muscle lost during the Fad Diet.
risky weight loss strategies
Risky Weight-Loss Strategies
  • High protein low carbohydrate:
  • The body is starved of its main source of energy (carbohydrate), and your brain of glucose, which it needs for normal functioning.
  • These diets are high in cholesterol and saturated fat, which are now established as major culprits in heart attacks and strokes. They are also void of fiber.

  • Meal Replacements: One or all the meals are replaced with a shake or bar.
  • This greatly limits the food options a person has, resulting in boredom and depression.

  • Diet Pills and Supplements:There are thousands of Diet pills on the market that claim to aid weight loss. All of them usually contain some or all of the following drugs: amphetamines like speed, ephedra a herbal version of speed, diuretics and laxatives
  • These ingredients cause a temporary increase in metabolism, and you go to the bathroom a lot more.

Risky Weight-Loss Strategies
  • Diet pills containing stimulants will speed up pulse rate, increase blood pressure, and increase heart rate.
  • Don’t be fooled by a diet pill claiming to be “All Natural”. Herbal diet pills, like Metabolife, containing stimulants, such as ephedrine, or ma huang, that pose the same serious health risks.
eating disorders
Eating Disorders
  • Anorexia Nervosa:The amount of calories consumed a day is very small (>1200).

  • This practice can lead to serious and even life-threatening problems, such as heart damage, kidney damage, and injury to all parts of the digestive system.
