Zone Diet - Pros and Cons
|
For
any diets, there are pros and cons. There are people agree and
follow it happily, and there are also people who disagree with
it.
Supporters who advocate the Zone Diet include celebrities and
also some health experts who say that the Zone’s recommendations
don’t stray far from the USDA’s (United States Dietary
Association) dietary guidelines.
The Pros
of
Zone Diet :
-
It doesn’t keep you hungry or deprived of good tasty
food to please your dear tongue.
-
The Zone Diet features good amounts of fruits and low
starch vegetables and is low in saturated fats,
restricts low nutrition carbohydrates, which is undoubtedly
good for overall health.
-
Since you are not significantly restricting
any one food source in Sears' diet, you are never
totally deprived of the foods you love.
-
If you successfully find your entrance to “The Zone” you
will experience slow, gradual, and permanent weight loss.
-
The main purpose of this diet plan that of balancing
insulin and glucagon - is fundamentally correct!
The Cons
of
Zone Diet :
-
Complicated and scientific; the 40/30/30 macronutrient ratio
represents the “mid point” to the entranceway of the
mysterious place of which Sears speaks—this can be tricky.
-
The daily caloric intake for this diet is determined by your
protein requirements - which can lead to incredibly low
daily caloric intake –much too low and sometime very hard to
stay on!
-
Claiming the 40/30/30 zone ratio creates a positive
eicosanoid balance isn't a bad theory - but it's a largely
unproven one.
-
Eliminates some essential vitamins and minerals found in
certain food.
-
Expensive to follow.
-
Time consuming and inconvenient.
Criticisms
The AHA
(American Heart Association) classifies the Zone Diet as high
protein and does not recommend it for weight loss.
They assert that the Zone Diet has not been proven effective
in the long term for weight loss. They believe that the
Zone Diet is hazardous as it restricts the intake of
essential vitamins and minerals present in certain foods.
They are concerned that the protein ratio in the Zone
diet is too high even if the minimal fat ratio is good.
They also find that the Zone Diet’s theory on
insulin flawed and argues that there is no scientific proof that
the hormone insulin plays a big role in weight regulation. The
metabolic pathways presented in The Zone which supposedly
connect diet, insulin-glucagon, and eicosanoids do not exist in
standard nutrition or biochemistry texts. The idea that the
Zone diet (or any diet) completely controls the secretion of
insulin and glucagon is not supported by the relationship
between nutrition and endocrinology . Next, the notion that the
insulin-glucagon axis controls the production of eicosanoids
is
not supported by biochemistry . And finally, the belief that
eicosanoids control all physiological functions (including
athletic performance, health, and disease) is not only
unfounded, it is an appalling over-simplification of complex
physiological processes.
