you're considering a new weight-loss plan, evaluate it by the following
statements to see how the program holds up. If one or more of these apply,
raise a red flag.
- Claims that sound too good to
be true
- Promises of a quick fix
- A complex study results in simplified
solutions
- Recommendations based on a
single study
- Dramatic statements that are
refuted by reputable scientific organizations
- Lists of "good" and
"bad" foods
- Opinions based on studies
published without peer review
- Studies that ignore differences
among individuals or groups
Some
Popular Diets
- Body-for-Life (Bill Phillips)
Phillips emphasizes portions, not calorie counts. This is a 12-week
fitness plan in which you eat a high-protein diet and exercise regularly.
You eat six meals a day, consisting of one portion of protein and one
portion of carbohydrates with some vegetables thrown in at prescribed
times. Once a week, you're allowed a "cheat" day to splurge on
your favorite foods. Although Body for Life emphasizes low-fat foods,
the diet doesn't consist of enough variety for a truly healthy diet to
meet all of your nutritional needs. This program's success is based on
testimonials and anecdotal evidence.
- New Diet Revolution (Robert
C. Atkins, M.D.)
This diet is about drastically reducing the intake of dietary
carbohydrates to force your body to burn your reserve of stored fat for
energy. This results in losing pounds and inches while still eating
protein and fat-laden foods. Meat, eggs, butter and most cheeses can be
eaten without restriction on this diet. The American Heart Association
(AHA) has published a position statement against high-protein diets
because weight loss that occurs as a result of a
high-protein/low-carbohydrate diet is likely to be mostly water weight.
They also warn that because this diet actually may have you eating
high-fat foods you may, therefore, increase your risk of heart disease,
high-cholesterol, liver and kidney damage, some cancers, and
osteoporosis.
- Sugar Busters! (H. Leighton
Steward and associates)
The authors of this diet claim that sugar is toxic to the body, causing
the body to release insulin and store excess sugar as body fat. This
diet recommends cutting sugar in refined and processed forms from the
diet. This includes: potatoes, white rice, corn, white bread beets,
carrots and sugar honey, corn syrup and foods containing them. By eating
more protein over time than the body needs, particularly if the source
is primarily animal protein, "bad" cholesterol increases. Long-term
effects of high-protein, high-fat intake may include kidney and liver
damage, heart disease and cancer. Sugar Busters! validity
is based on opinions, not proven facts, and is supported by testimonials
and anecdotal claims.
- The Zone diet (Barry Sears,
Ph.D.)
In this diet, used by stars such as Jennifer Aniston, meals should
contain carbohydrates, proteins and fats in the ratio of 40 percent, 30
percent, 30 percent, respectively. A sample meal may be 2 cups of pasta
(carbohydrate), a 3-ounce piece of steak (protein), and a small handful
of nuts or other fats to round out the meal. The typical zone diet
contains less than 1,000 calories, which may result in an inability to
meet vitamin and mineral needs for most people, although not as
restricted as other high-protein, low-carbohydrate diets, The Zone diet
has not been validated scientifically. There's no scientific reason for
eating set combinations of foods at set times.
