This is the advice given by a recent
Harvard University in its newsletter for people who are overweight or obese.
In an attempt to help people choose between diets different offers
Harvard presentation of some of these diets, such as diet low in fat, such as
those known as Ornish and Paritikin diets and diet few elements carbohydrates
such as Atkins and South Beach and those diet system's Mediterranean, which
includes a lot of benefits health.
The truth is that when we talk about
weight loss, the foundation is to reduce the calories in the food we eat does
not matter much whether these calories come from a piece of meat or a loaf of
bread or vegetables.
In a previous study researchers at Harvard
published in 2009 in the Journal of New England Medical researchers comparing
four diets to lose weight for 811 adults are overweight, and despite the fact
that all the participants got rid of 13 pounds on average during the first six
months (which is similar to some 7% of their real weight), they began to regain
some of the weight in the first year, after two years the average weight loss
was one in every group.
Has proposed a previous study published in the
Journal of the American Medical Association that the difference occurs in
accordance with the commitment of the diet chosen by the person.
A year
later came out almost half of the respondents of the study, but people who have
continued to participate have lost the same amount of weight (5 to 6 pounds each
on average). The researchers noted that most of came out of the study were not
able to follow-up were from the group that followed the Atkins diet and Ornish,
which predicts that a lot of people find these systems extremist in severity.
But for some others stick to the strict plan may be the solution that helps to
get rid of excess weight.
Experts advise people to abide by percentages
of calories from macronutrients and in accordance with the recommendations of
the federal official, as follows:
• Protein: 10 to 35%
•
Carbohydrates: 45 to 65%
• Fat: 20 to 35%
It is noted that a diet
consisting of carbohydrates, less than 45% and more than 35% fat is difficult to
follow. It also does not come with the result desired. May increase the risk of
heart disease and have a negative impact on a person's mood, says previous
studies.
Hence Harvard provide an attempt to analyze and compare three
diets:
1 - a low-fat diet, which is characterized by bad taste and lack
of saturation
And to follow a low-fat diet they recognize the fact that
some healthy fats help in weight loss and some fat be beneficial to heart
health. To this Vanqas these fats in our diet can cause numerous health
problems.
Since fat contains 9 calories per gram, while containing
carbohydrates on 4 calories, you can theoretically doubled the quantities of
food you eat without increasing calories heat within the body by reducing
high-fat foods and eat more foods rich in carbohydrates, such as fruits and
vegetables rich in water. However, this diet seems less rewarding and taste
compared to other Balhmyat which weakens their attractiveness in the long run.
2 - diet Low carbohydrate elements:
And result in rapid weight
loss, but with the advent of health problems in the long run, this strategy
relies on the fact biological says that eating a lot of carbohydrates raise
blood sugar level which raises the flow of insulin from the pancreas. The theory
says that the high level of insulin increases the feeling of hunger. And
therefore, people who eat a lot of carbohydrates take more calories and gain a
lot of weight.
And cause few elements carbohydrate diet in causing
drought and because the body assisted Bmkhozouna of carbohydrates in the liver
and muscle tissue to compensate for the lack of these substances in the food
inside it. In this process to get rid of the body as well as of water, which
means that the lack of weight is the weight of the water from the body. The
result is a rapid phase of weight, but after a few months back, this lack of
weight and then the body begins to recover what was lost weight as happens with
other diets.
The American Heart Association warns of Atkins diet because
they are rich in saturated fat and protein that are harmful to the health of the
heart, kidneys and bones. As they do not contain adequate amounts of fruits and
vegetables raises the ire of health experts as these foods have significant
benefits in reducing the risk of stroke and dementia and some types of cancer.
3 - Mediterranean diet:
And include healthy fats and
carbohydrates with a large part of the fruits and vegetables, as saturated fats
and trans fats and cholesterol are bad guys, while fat offices are in those
found in olive oil, for example, and some foods such as fish and nuts.
Your diet Mediterranean region is characterized by a moderate amount of
fat and many of them come from healthy fats and trans fats Omega 3. This system
also rich Aalkrbuhedrat which comes mostly from foods rich in fiber and
unrefined grains.
It is also rich in fruits, vegetables, nuts, grains
and fish with a moderate amount of meat and cheese, so the peoples of the
Mediterranean basin have lower rates of heart disease.
