High Protein Low Carb Diets
The high-protein low-carb diet was popular
in the 1970's, before saturated fat and heart disease became closely associated.
Now, high-protein low-carb diets are once again popular due to the faster
initial weight loss they can achieve. However, many dietitians
retain doubts about the long term health effects of these carb-restricted
weight loss plans.
That said, recent (albeit small-scale)
studies suggest that high-protein low-carb diets may be less harmful and
more beneficial than supposed. A futher long-term study is underway. This
should help to clarify the health and safety issues of high protein diets.
Weight Loss or Water Loss?
Although high-protein low-carb diets
may lead to fast weight loss in the short term, much of this may be
water loss. This is because when the body is starved of carbs it takes
energy from it's glycogen stores. And each gram of glycogen has 4 grams
of water attached. So although weight loss looks good, much of it is
water. As soon as carb intake returns to normal, much of this 'water-weight'
is regained.
High-protein low-carb diets tend to
encourage over-consumption of saturated fat and cholesterol, which in
turn leads to increased risk of heart disease and some cancers.
Weight Gain When Diet Stops
According to sceptics, high-protein low-carb ketogenic diets can bring
about changes in a dieter's fat cells causing these fat cells to accumulate
even more fat when the person comes off the diet. They can also cause
mood changes like tension and irritability, which may result in cravings
for high carb foods and fatty snacks.
High-protein low-carb diet plan
The diet is based on eating lots of
protein like meat and eggs but almost no carbohydrates like bread, potatoes,
pasta, or rice, at least for a period of time.
Most versions recommend large quantities
of protein in unrestricted amounts, including red meat, fish, shellfish,
poultry, eggs, and cheese. They forbid (or limit) pasta, bread, potatoes,
fruit, many vegetables, plus any foods with large amounts of refined
sugar.
What Sceptics Say About High-Protein
Low-Carb Diets
High protein diets tend to cause problems
with mood changes, resulting in cravings for carbohydrate-rich foods
and snacks.
By contrast, higher carb diets tend
to raise the level of serotonin (the feel good brain hormone) thus improving
mood and appetite. A recent study, reported in
Obesity journal,
followed a number of obese women with a long history of yo-yo dieting
who followed either a higher carb diet, or a high protein diet of 1400
calories. The higher carb dieters had fewer cravings and better overall
moods than those on the high protein diet. These also lost significantly
more weight than those on the high protein diet plan.
High protein diets violate several dietary
and nutritional guidelines of the US Government and the American Heart
Association. In addition, the dietary guidelines laid down by the World
Cancer Research Fund contradict many of the recommendations in many
high protein diets, with the exception of those concerning refined sugar.
By overloading dieters with protein,
high protein diets can lead to loss of calcium from bones, which may
lead to osteoporosis. They also pressurize the kidneys as they try to
eliminate large amounts of urea, a by-product of protein metabolism.
Carbohydrate is a nutrient group which
is readily converted to energy. By minimizing carbohydrate consumption,
high protein diets can quickly lead to tiredness and fatigue.
Carbohydrates are also good for your
brain. A shortage of carbohydrate can cause loss of concentration and
a slow down in reactions.
