This calorie thing. By what mechanism does the body recognize an
excess of calories and by what mechanism does the body then trigger
fat storage. Conversely, by what specific mechanism does the body
detect a dietary calorie deficit and by what mechanism does it then
trigger fat burning.
What are the specific bio-chemical steps in both processes?

I have read many articles about eating like a Mediterranean. Apparently it
works for many people. But, there is also the activity. If you look at some
of the life styles of these people, many of them are hard working. They are
either fisherman, doing manual labour, or working in the fields.
Calories are a form of energy. The energy that we do not use, is stored as
fat. There is the simple physics that shows that the calories out must be
the same as the calories going in, if the person is not to change in weight.
To loose weight, the calories going out must be greater than the calories
going in. I like these people who tell me that they don't eat anything...
For the average person, who is not particularly active, a defecate of 3500
calories over a given period of time, will result in a loss of 1 lbs. If
someone was having a deficit of 1000 calories per week, after 3.5 weeks,
they should loose 1 lbs. In a descent weight loss plan you would want to
have a weight loss of at least 3 to 4 lbs per month. Too rapid a weight loss
it not very easy on the system, and can result in the person going on eating
binges and gaining it back again.
The general key to descent weight control is to follow a low fat diet, and
participate in a lot of exercise. Being very physically active is a big plus
to loose and control weight. A moderate amount of exercise also helps to
control blood pressure. Following a diet that consists of the proper
portions of food, is well balanced, and is low on fat is the key. The diet
should be consistent. Ideally the total fat intake should not exceed about
60 to 80 grams. The average person eats over 150 grams of fat per day. Each
5 grams of fat is about 1 tsp, or about 45 calories. Foods such as butter,
or margarine are about 98% fat.
Cutting out butter, all fried foods, and only eating lean meats with a lot
of assorted vegetables, will help out to loose weight. An average portion of
meat should be about 4 to 6 oz, not including the bone in the cut. When
eating a salad, use low fat dressings. You can use some oil and vinegar with
your favourite spices, but care should be taken when eating foods with oil.
This will add up to the total fat.
Stay away from foods that have trans-fats, or hydrogenated fats. These are
the worse for blocking up the arteries. Most candies, cookies, and fast
preparation foods have bad fats.
A proper diet, with a lot of exercise is what will keep someone in good
health.

Two new studies confirm the health benefits of eating the
Mediterranean way.
In a study in today's Journal of the American Medical Association,
mortality rates were 65% lower among elderly people who combined a
so-called Mediterranean diet with 30 minutes of daily exercise,
moderate drinking and no tobacco use.
Although experts say there is no single Mediterranean diet, doctors
say cuisines from these regions favor olive oil rather than butter and
include lots of legumes, nuts, seeds, grains, fish, vegetables and
potatoes but little meat and dairy.
The study was conducted from 1988 to 2000 and led by researchers at
Wageningen University in the Netherlands and other European
universities. More than 2,300 healthy people ages 70 to 90 answered
questions about their eating habits and activities. Researchers noted
that the study suggests a strong association between healthy habits
and longer life but offers no proof.
In a separate study in the same journal, researchers from the Second
University of Naples in Italy found that Mediterranean-style diets
helped patients with "metabolic syndrome," which increases the risk of
heart disease and diabetes and affects 1 in 4 American adults.
People with the syndrome are fat around the middle, have high blood
pressure and cholesterol deposits in their arteries, and do not
properly process glucose. After two years, 44% of those on the
Mediterranean diet still had features of metabolic syndrome, compared
with 86% of others.
This research confirms the results of earlier studies, experts say. A
previous study of heart-attack survivors showed that the mortality
rate was 70% lower among those who followed a prescribed Mediterranean
diet compared with people on a low-fat diet.
"The Mediterranean experience makes it clear that healthy eating is
completely consistent with wonderful eating," says Walter Willett,
chairman of nutrition at the Harvard School of Public Health.
Yet getting more Americans to adopt healthy living will be a
challenge, says Dario Giugliano, an author of the metabolic syndrome
study. Experts say only 1 in 5 Americans eat the recommended five to
nine servings of fruits and vegetables a day.
