Title: FAD DIETS


1
FAD DIETS
  • University of Kentucky
  • Cooperative Extension Service

2
Obesity
  • Approximately 127 million adults in the United
    States are overweight.
  • 60 million are obese.
  • 9 million are severely obese.
  • Obesity is a disease that has been rapidly on the
    rise in America since 1960!

3
Why are so many Americans obese?
  • Lack of physical activity
  • Poor food choices, namely high-calorie, low cost
    foods
  • Obsession with the wrong kinds of diets
  • Lack of time
  • Lack of quality relationships

4
How to recognize a fad diet…
  • Advocates magic or miracle foods that burn fat.
  • Recommends bizarre quantities of only one food or
    type of food.
  • Forces one to adhere to a rigid menu.
  • Touts benefits of specific food combinations.
  • Promises rapid weight loss (2 lbs. per week)
  • Does not include a health warning for those with
    chronic diseases.
  • Requires NO increased physical activity.
  • Sounds too good to be true.

5
Popular Fad Diets
  • South Beach Diet
  • Atkins Diet Revolution
  • Scarsdale Medical Diet
  • Grapefruit Diet
  • Enter the Zone Diet
  • 3-Day Diet

6
South Beach Diet
  • Eat as much as you want, BUT avoid sugars and
    refined-foods carbohydrates.
  • Phase One- 2 weeks of strict dieting avoid
    nearly all carbs. Most people lose between 8-13
    lbs.
  • Phase Two- Good carbs slowly introduced into
    diet.
  • Phase Three- Return to Phase One if weight gain
    begins again.

7
Dr. Atkins Diet Revolution
  • Eat NO MORE THAN 20 grams of carbohydrates per
    day.
  • Avoid ALL breads, cereals, grains, sugars, pasta,
    rice, flour, soda, juice, fruit, alcohol…
  • Some vegetables are allowed if consumed in small
    quantities. The dieter is advised to stick with
    free meats, eggs, and cheeses.
  • Advocates LOW carbs and HIGH fat.

8
Scarsdale Medical Diet Plan
  • Requires dieter to follow a strict diet regimen
    for 7 days.
  • Must consume at least 4 glasses of water or diet
    soda per day.
  • Coffee, lean meat, vegetables, and melons or
    grapefruit make up the majority of the diets
    food guidelines.

9
Grapefruit Diet
  • Promises that the dieter will lose 52 lbs. in 2½
    months!
  • Must drink 64 oz. water daily. Must adhere to a
    strict list of haves and have nots. Cannot
    eliminate ANYTHING from the diet and must consume
    the minimum amount required at each meal.
  • Advises the dieter to, Eat until you are
    stuffed. The more you eat, the more weight you
    will lose.
  • Includes grapefruits or juice, any meat
    (especially bacon), and salad with dressing.

10
Enter the Zone Diet
  • Strict 40-30-30 eating plan. 40
    carbohydrates, 30 fat and 30 protein.
  • Claims to use the biochemical effects of food on
    hormone production and metabolic activity. The
    Zone refers to a supposed state of optimal
    health, peak performance, and weight control.

11
3-Day Diet
  • Similar to the Scarsdale diet, but offers a wide
    variety of food and necessitates a VERY detailed
    eating plan.
  • Dieters are instructed to measure each food
    (usually ½ or 1 cup per serving) and are told to
    eat toast, peanut butter, veggies, apples,
    crackers, vanilla ice cream, and beef franks.
    Again, the diet stresses the importance of eating
    these foods in a certain specific order.

12
High-Carbohydrate Diets
  • Diets like the Pritikin Diet Plan or the
    Save-Your-Life Diet recommend high fiber and high
    carbs.
  • These diets are as unhealthy as their low-carb
    counterparts. They can lead to lowered immunity
    and poor wound healing because of lower fat and
    protein intake.

13
Science of Low-Carbohydrate Diets
  • Carbohydrates are the bodys main source of
    energy. Excess carbohydrates are converted to
    fat and stored as fat tissue.
  • When on a low carbohydrate diet, the body uses
    fats from foods and fats stored in the body for
    energy.

14
Science of Low Carbohydrate Diets
  • When carbohydrates are in short supply, the body
    cannot completely break down fat. As a result,
    ketone bodies are formed. Large amounts of water
    is excreted. This water loss can cause
    dehydration.
  • Ketones accumulate in the blood, causing ketosis.
    This state forces the body to burn calories
    similar to a state of starvation. This is
    DANGEROUS, especially over a long period of time.

15
Other Dangerous Plans
  • Many people try total fasting or self-imposed
    starvation to lose weight. This is perhaps the
    most problematic method of weight loss and can
    damage tissues, body fluids, mineral supplies,
    and vital organs.
  • Diet Aids, such as Dexatrim or PhenPhen promise
    the same results as diet plans but with little or
    no change in eating or exercise lifestyle.
    Generally, they are a health risk and are often
    make claims that are too good to be true.

16
Psychology of Dieting
  • Fad diets are SO popular because they promise
    FAST weight loss with MINIMAL effort. In our
    fast-paced society, this is a very tempting
    offer.
  • Americans are obsessed. The weight loss industry
    in the U.S. rakes in 37 billion dollars a year.

17
Psychology of Dieting
  • A study of four popular fad diets discovered
    another problem while they claim to be easy to
    follow, most people cannot adhere to them. A
    third of participants dropped out of the more
    healthy Weight Watchers and Zone diets. About
    half could not complete the Atkins Diet or the
    vegetarian Ornish Diet Plan. Source Tufts
    University

18
Psychology of Dieting
  • The study also noted that, while initial weight
    loss may be high, the participants had only lost
    about 5 of body weight after one year.
  • This weight loss is comparable to a 200 lb.
    individual shedding 10 lbs. Most dieters hope to
    shed about 30 lbs.
  • Even unhealthy weight loss can be DISCOURAGING!

19
THINK POSITIVELY
  • Be realistic.
  • Make small changes.
  • Be adventurous.
  • Enjoy a variety of foods.
  • Be flexible.
  • You can fit in special treats.
  • Be sensible.
  • Enjoy all foods.
  • Be active.
  • Get creative with your recreational activities.

Teen Dieting
  • Time Magazine reports that 80 of children have
    been on a diet by the time they reach the 4th
    grade.
  • 81 of ten-year-olds are afraid of being fat.
    (Mellin,et.al, 1992)
  • The most common behavior that will lead to an
    eating disorder is dieting. (AABA, 1998)

22
Teen Dieting
  • Too often, teenagers believe that they are
    supposed to look a certain way.
  • The media presents us with unrealistically thin
    models. The average woman is 54 tall and weighs
    140 lbs. The average model is 511 tall and
    weighs 117 lbs. (Smolak, 1996)
  • Pre-teen and young teen girls go through normal
    and necessary body changes (hips broaden, breasts
    develop) and no longer look like the models on TV
    and in magazines.

23
Fad Diets and Eating Disorders
  • 35 of normal dieters progress to pathological
    dieting. Of those, 20-25 progress to partial or
    syndrome eating disorders. (Shisslak
    Crago,1995)
  • The popularity of fad diets perpetuates the idea
    that being thin is more important than being
    healthy.
  • According to a recent study, ½ of females between
    the age of 18-25 would prefer to be run over by a
    truck than be fat. (Graessar, 1996)
