What’s the risk of fad diets?
Ketosis - Fad
diet is considered an unbalance diet; it eliminates or minimizes carbohydrates
in your diet which synthesizes or creates fat in your body. Carbohydrates
contained in food are converted into glucose which is then transported around
the body and is particularly important in fuelling brain functions. A low carb
diets may increase your risk of ketosis. Ketosis is a condition in which your
body breaks down fat for energy. A little carbohydrate in the diet may result
to the liver to convert fats into fatty acid and ketone bodies. These ketone
bodies pass into the brain and replaces glucose as an energy source. An
elevated level of ketone bodies in the blood may result to fruity smelling
breath, loss of consciousness and worst coma. According to the research
conducted at Dartmouth Medical School and published in the "Annals of the
New York Academy of Sciences" in 2005 discovered that people on the Atkins
diet burn fat as fuel, develop ketosis.
Kidney trouble
– The production of uric acid and calcium oxalate, substances associated with kidney
stones and gout usually increases with low-carbohydrate and high protein
diets. This fact is confirmed by the
research at the Department of Internal Medicine at the University of Chicago
and published in the "American Journal of Kidney Diseases" in 2002 which
says that consumption of a low-carbohydrate high protein diet in six weeks can
increase risk of kidney stones. Further low-carbohydrate, high-protein diets
increases urinary calcium and decreases calcium level in the body leading to
increased risk of bone loss.
Gain on Weight
– Contrary to your objective fad diets let you gain weight. Due to low
adherence, fad diets may help you lose weight but will not help you sustain the
lost weight for long. Research by
scientists at Tufts-New England Medical Center and published in the
"Journal of the American Medical Association" in 2005 evaluated the
effects of weight loss on four popular diets and found that at the end of one
year, participants who adhered to the respective diet lost an average of 2.1
kilograms on the Atkins diet, 3.0 kg on the Weight Watchers diet, 3.2 kg on the
Zone diet, and 3.3 kg on the Ornish diet. Among those who began each diet, 50
percent completed the Ornish diet, 53 percent completed the Atkins diet, and 65
percent completed the Zone or the Weight Watchers diets.
Malnutrition –
Women on fad diets is most likely to increase risk on vitamin and mineral
deficiencies as well as lack of nutrients.
Due to restriction on the amount of food intakes, women maybe vulnerable
to insufficient calcium and iron needed for bones and red blood cells.
According to American Heart
Association the following are possible risks posed by fad diets.
·
Nutritional
deficiencies caused by a lack of a balanced diet.
·
Lack
of physical activity from emphasis on diet only can increase the risk of heart
disease.
·
Lack
of variety in foods can cause boredom and frustration, and make it difficult to
maintain the diet for more than a brief period.
·
Severe
restrictions on the foods you can eat may make it difficult to establish and
maintain a healthy diet in the future.
·

quick weight-loss diets are based on unfounded claims that may do more harm
than good.
