Nonsense slimming diets
Part 7: Conclusion
The science of nutrition is highly complex and the emergence of products
like Olestra and Xenical illustrate how little is known about the vital part
that fat plays in our health and wellbeing. Nutrients interact: a deficiency
of one can have a profound effect on the metabolism of others. Today, a
lack of dietary fat probably causes a wider range of abnormalities than
deficiencies of any other single nutrient.
Fat has a high calorific value, which is why all modern low-calorie diets
restrict fats, but this can be dangerous and self-defeating. Not only does
restriction of dietary fat cause the problems already mentioned, it can also
cause dry skin and eczema; damage to ovaries in females and infertility in
males; kidney damage and weight-gain through water-retention in the
body. When there is little or no fat in the gut, there is nothing to stimulate
the production of bile, the gall bladder is not emptied and the bile is held
in reserve. This leads to the formation of gallstones. If a fat-free diet is
continued for a long time, the gall bladder may atrophy. And, although
most patients come through a gall bladder operation successfully, it is a
life-threatening operation. It also removes the gall bladder a necessary part
of your digestive system.
Malabsorption of the fat-soluble vitamins A, D, E and K has
consequences for yet more nutrients. Without vitamin D and fat present in
the intestine, for example, calcium is not absorbed. For a woman, whose
chance of suffering from osteoporosis is high, this is an important
consideration. Slimmers are usually told to drink skimmed milk. This has
the advantage, they are told, that it contains more calcium than full-cream
milk. This is true but skimmed milk does not contain fat. As a
consequence, only about five percent of the calcium in skimmed milk is
absorbed compared to around fifty percent from full-cream milk. This
small absorption of calcium is reduced still further if the skimmed milk is
eaten with a bran-laden breakfast cereal (see Chapter 7). Calcium-enriched
milk sold in supermarkets may seem worth the extra expense but it is
invariably calcium-enriched
skimmed
milk and, without the cream, all that
extra calcium ends up down the toilet.
All body cells require a continuous supply of various fatty acids. If
insufficient are supplied from food, the body tries to make them from
sugar. This causes blood-sugar levels to fall, you feel very hungry and eat
more, generally of the wrong things and gain weight.
Fat also has a satiety value: it takes longer to digest and stops you
feeling hungry. Eat a hundred calories less fat at a meal and you will
probably feel hungry so quickly that you will eat three times as many
calories in the form of sugary or starchy foods because they are
convenient.
Lastly, it seems that the gut's nutrient-measuring system works so well
with fat that it is difficult, if not impossible, to eat too much of it. Try and
you develop an aversion to it. But, for the same reason, eating fat stops
you eating too much in total. If your body needs ten grams of fat, your
appetite will not be satisfied until you have consumed that ten grams of fat.
If you eat those ten grams as an ounce of Cheddar cheese, you will take in
about 125 calories. If you eat them as wholemeal bread thinly spread with
a very-low-fat spread, you will need to eat eight slices a total of about 500
calories!
A third of the American population is now overweight. The situation in
Britain is almost as bad. It is no coincidence that this huge increase in
obesity has happened at a time when people generally are being exhorted
to eat less and less fat. It is merely further evidence for what has been
known for a very long time: the less fat you eat, the fatter you will
become.
Fat for prolonged exercise
Athletes, like the rest of us, are usually told to eat a diet high in
carbohydrates and low in fats. This, they are told, will increase their
performance. However, this was not confirmed in a dietary study
published in 1994. Using three diets: normal, high-fat and high-carbohydrate,
the study showed that the high-carbohydrate diet increased
performance by an average ten percent over a normal mixed diet. Not bad,
you might think, but the high-fat diet increased performance by a massive
thirty-three percent. That's much better. The authors conclude that
restriction of dietary fat may be detrimental to endurance performance. So,
once again, fat is best.
Conclusion
The reason that modern slimming diets all fail is because of what they all
have in common - they are all low-fat, low-calorie diets that restrict the
intake of food to such an extent that the slimmer is starving. Second World
War concentration camps proved that it was possible to lose weight by
starving - but that was hardly a secret. It is neither the ideal way nor is it
the natural way.
Natural Health & Weight Loss
does not restrict calorie intake at all:
it relies on your body's natural energy-regulating mechanisms to regulate
your calorie intake for you. You really can eat as much as your body tells
you it wants provided only that carbohydrate intake is controlled. There are
five other important differences, however, and they are:
a. You can live on the
Natural Health & Weight Loss
diet for the rest of your life
without ever again being hungry. There is no stressful 'yo-yo' effect.
Instead of starving the weight off, it gets the body to burn fat more
efficiently.
b. It is very easy to live with and maintain socially. As all you have
to do is reduce your intake of carbohydrates, you can eat what your
hostess puts before you without having to disclose that you are 'on a
diet'. It is only necessary to take a little more meat and a little less
pudding.
c. With this diet, your weight cannot go below your natural weight.
This is important. Being overweight may be undesirable but being
underweight is potentially far more dangerous as there are serious risks
of sudden death associated with extreme leanness.
d. It is a much more healthy diet.
e. It is a much more natural diet.
