Since high protein diets limit the quantity of food you take
in, you can more often than not lose weight using them. The
trouble with these diets is that they cause the body to go
into a ketogenic state where it must rely on stored fat for
energy, and this is harmful for quite a few reasons. Because
the body attempts to get rid of ketones through the liver
and kidneys, it places a severe strain on these organs.
We’ve all heard about high protein diets. You get to
consume high fat food, as much of it as you desire –
these diets appear too good to be true! A quick look …
• High protein diets are high in fat and calories.
• Science and research have revealed that a high fat
diet can cause heart disease, osteoporosis, kidney stones,
diabetes, colorectal cancer, and even loss of life.
• Research has shown that protein diets do not result
in more weight loss than high carbohydrate diets
• Carbohydrates found in fruits and vegetables reduce
your risk for cancer
Your local bookstore, the Internet, everywhere is flooded
with high protein diets. The majority of these diets do not
permit carrots or potatoes, but they allow limitless amounts
of fat and protein. Having reappeared from their glory days
in the 1960s and 70s, high protein diets are fashionable at
the moment. The main assertion behind nearly all high-protein
diets is that insulin, not calories, makes you fat.
Starting with the efforts of Dr. Robert Atkins in the late
sixties, alternative doctors have recommended a protein-centric,
low-carb diet as a way to drop weight and feel more energized.
They say carbs cause highs and lows in energy levels, in addition
to increased manufacture of insulin. Zone advocate Dr. Paul
Kahl wrote “elevated insulin combined with excess carbohydrate
calories lead to increased triglycerides, obesity, and production
of pro-inflammatory eicosanoids.”
The American Heart Association, the American Dietetic Association
and the American Kidney Fund don’t recommend high-protein
diets for weight loss. Most of these diets aren’t balanced
in terms of the vital nutrients our bodies require. Getting
rid of carbohydrates causes a loss in body fluids, so these
diets can result in a rapid drop in weight. However, most
Americans already consume more protein than their bodies need.
A number of the current media reports that have publicized
the immediate weight loss that sometimes happens with the
use of high protein diets have distorted medical details and
have disregarded the possible dangers of such diets. The ingestion
of fruit, fruit juice, starchy vegetables, beans, bread, rice,
cereals, pasta and other grain products, and all other foods
containing carbohydrates is removed or radically limited by
such plans, leaving an inadequate diet of foods that have
chiefly fat and protein: meat, cheese, non-starchy vegetables,
and very little else.
Up until now only testimonials and unconfirmed reports, together
with advertising and publicity have been offered as proof
that these diets work. Only a few studies document the capacity
of a high-protein diet to influence body fat loss. The existing
recommended daily dietary allowance for protein is 0.8 grams
per kg of body weight. Many high protein diets advocate consuming
about 2.4 grams per kg, a quantity that may have unsafe side
effects, particularly in certain populations.
Protein is a very important nutrient, necessary for your well-being.
The average American consumes about twice as much protein
as the body in fact needs. Most people are oblivious to the
amount of protein and fat contained in the foods they eat.
The high intake of protein leaches calcium from the bones,
which leads to osteoporosis. Medical data shows that the body
gets rid of an average of 1.75 milligrams of calcium in the
urine for every 1-gram increase in animal protein ingested.
In people with early problems, high-protein diets can speed
up the loss of kidney function. The trouble is, as many as
20 million Americans are in danger of reduced kidney function
but don’t know it. There are no warning signs attributable
to this early kidney disease, but it’s very common.
Those at highest risk are people with high blood pressure,
diabetes, or those older than age 65.
In 2003 the United Kingdom Government’s Food Standards
Agency issued an official caution saying high protein diets
can set off killer diseases. But other experts say that’s
unscientific garbage. The high protein diets, they claim,
are just ordinary eating habits, practiced safely for centuries
in traditional societies – from the San of Southern
Africa, to the Inuit in Northern Canada, and the Aborigines
in Australia who consumed mostly fatty protein, such as meat
and fish, with no adverse effects on their health.
The discussions concerning high-protein, low-carbohydrate
diets is not expected to subside anytime soon, particularly
following information presented to the American Heart Association
suggesting a connection between high protein diets and enhanced
insulin resistance sensitivity, chiefly in men. Should clinicians
persuade their patients who have insulin resistance syndrome
to get on high protein diets? For now, the answer is no, until
more research is done to determine the long-term effects of
these diets.
Fascinatingly, kidney disease is far less frequent in people
who eat a vegetable-based diet than it is in people who eat
an animal based diet. By substituting animal protein with
vegetable protein and replacing saturated fat with unsaturated
fat, like those found in olive and canola oils, you can keep
away from the drawbacks of the usual high-protein diet.
