is forced to wonder how the thousands of
scientists working on obesity research over the
past century could possibly have missed such
obvious connections.

12What is a Fad Diet?
- A fad diet is a weight loss plan or aid that
promises dramatic results. These diets don't
offer long-term success, and they are usually not
very healthy. American Academy of Family
Physicians
13American Heart Association
- We want to inform the public about misleading
weight-loss claims. Many of these diets like
the infamous Cabbage Soup Diet can undermine
your health, cause physical discomfort and lead
to disappointment when you regain weight soon
after you lose it
14American Heart Association
- Quick-weight-loss diets usually overemphasize
one particular food or type of food. They violate
the first principle of good nutrition Eat a
balanced diet that includes a variety of foods.
If you are able to stay on such a diet for more
than a few weeks, you may develop nutritional
deficiencies, because no one type of food has all
the nutrients you need for good health. The
Cabbage Soup Diet mentioned above is an example.
This so-called fat-burning soup is eaten mostly
with fruits and vegetables. The diet supposedly
helps heart patients lose 1017 pounds in seven
days before surgery. There are no "superfoods."
That's why you should eat moderate amounts from
all food groups, not large amounts of a few
special foods
15American Heart Association
- These diets also violate a second important
principle of good nutrition Eating should be
enjoyable. These diets are so monotonous and
boring that it's almost impossible to stay on
them for long periods. - http//www.americanheart.org/presenter.jhtml?ident

16How to identify Fad Diets
- Promise dramatic, rapid weight loss
- Promote diets that are nutritionally unbalanced
or extremely low in calories - Use liquid formulas rather than foods.
- Attempt to make clients dependent upon special
foods or devices. - Fail to encourage permanent, realistic lifestyle
changes. - Understanding Nutrition, 8th ed. Pg 253
17How to identify Fad Diets
- Misrepresent salespeople as counselors
supposedly qualified to give guidance in
nutrition and or general health. - Collect large sums of money at the start or
require that clients sign contracts for
expensive, long-term programs. - Fail to inform clients of the risks associated
with weight loss in general or the specific
program being promoted. - Understanding Nutrition, 8th ed. Pg 253
18How to identify Fad Diets
- Promote unproven or spurious weight-loss aids
such as starch blockers, diuretics, sauna belts,
body wraps, passive exercise, ear stapling,
acupuncture, electric muscle-stimulating devices,
amino acid supplements, unique ingredients, etc - Fail to provide for weight maintenance after the
program ends. - Understanding Nutrition, 8th ed. Pg 253
19If fad diets don't work, why are they so popular?
- People are often willing to try anything that
promises to help them lose weight because they
want to look or feel better, or because they are
worried about getting weight-related diseases.
Companies that promote fad diets take advantage
of this fact. They appeal to people by promising
weight loss that's very quick and easy. Many
people prefer to try the quick fix of a fad diet
instead of making the effort to lose weight
through long-term changes in their eating and
exercise habits. - American Academy of Family Physicians (AAFP)

20If fad diets don't work, why are they so popular?
- Fad diets also become popular because many of
them do work for a short time. In many cases,
this is because when you stop eating certain
types of food or eat special combinations of
foods, you are getting fewer calories than you
normally would. You are also paying more
attention to what you are eating. However, its
likely that much of the weight you lose is from
water and lean muscle, not body fat. Also, most
people are not able to keep up with the demands
of a diet that strictly limits their food choices
or requires them to eat the same foods over and
over again. People who use fad diets usually end
up gaining back any weight that they lost. - American Academy of Family Physicians (AAFP)

39Key Messages National Nutrition Month 07
- Develop an eating plan for lifelong health. Too
often people adopt the latest food fad rather
than focusing on overall health. Get back to
basics and use the Dietary Guidelines 2005 and
MyPyramid as your guide to healthy eating. - American Dietetics Association www.eatright.org
40Key Messages National Nutrition Month 07

break a healthful diet. When consumed in
moderation in the appropriate portion size, all
foods can fit into a healthful diet. - American Dietetics Association www.eatright.org
41Key Messages National Nutrition Month 07

are an instrumental part of developing a diet
plan that is unique to your particular needs. - American Dietetics Association www.eatright.org
42Key Messages National Nutrition Month 07
