Either because of fear given the rates of obesity and overweight continues to rise. Also because many people want to slim down, in order to appear more attractive to use in addition to her favorite fashion look sexier. Even some people who go on a diet because the doctor ordered, for reasons of health. But many people mistakenly understand the concept of dieting.
"With a wide choice of diet, and so as not to confuse vote, everyone should know how to distinguish between diet, which is less healthy for the body in the future. Therefore, everyone should understand the concept of diet before the vote or run it," said Simpson in talk- Be Smart-themed talk Nutrifood Choosing Your Diet, at the fX Lifestyle X'nter Jakarta, Wednesday (09/05/2012).
Miller describes four concepts fad diets that people need to be understood. What exactly is fad diet? Fad diet is a diet that requires you to reduce or eliminate one of the components of daily food, get the lure to lose weight in quick time, only 800 kcal per day mengasup. Such a diet may have managed to lose weight in a short time However the short term and threaten health in the long term.
To understand the concept of this diet, remember the concept of diet and caloric needs. Basically every individual, require the intake of carbohydrates (55-60 percent of calories), fat (20-30 percent), and protein (15-20 percent), every day. While the total average calorie needs of adults up to 2,000 kcal per day.
Four concepts fad diet:
A. High Protein Diet and Karbo.
This concept refers to a reduction in dietary fat intake (20-30 percent per day of daily caloric needs). That is, people who diet in this way will eliminate the fat in makanan.Sebagai compensation, the followers of this diet of carbohydrates and protein mengasup higher than normal.
The study of 50,000 people who use the concept of this diet, suggesting a period of 7.5 years to avoid fat diet, the average body weight decreased 1.9 kg. Diet increasingly ineffective because it is not accompanied by exercise and stress management.
"A diet like this can not affect the long term, especially if the only diet without exercise and stress management. In some people, when stressed he tends to eat more," said Miller, adding the concept of such a diet also causes a deficiency of vitamin D obtained from fat.
The impact of the concept of this diet in which the risk of heart disease, because carbohydrate intake is higher than it should.
2. High Protein Diet Low Karbo
The concept of this diet has been around since 1860, and the second choice after a lot of people are failing to Karbo and High Protein Diet. The concept of this diet is the second cut of the recommended daily carbohydrate needs 300 grams per day to only 20-30 gr.
"Intake of 20-30 grams of carbohydrate per day is equivalent to one slice of bread," explained Miller.
He added that every day each person needs 3-8 servings of carbohydrate per day. One serving equals one cup of white rice. Even so, the intake of carbohydrates is not only derived from rice, but can of potatoes or other foods.
These include the impact of diet, you urinate frequently, causing a loss of 1 kg of water from the body, and cause bad breath, and troubled the brain, causing impaired thinking like lack of concentration.
"This diet reduces the body's water reserves of about 1 kg for a diuretic. In other words, you will lose 1 kg of water from the body, because too often issued in the form of urine. Other impacts, you will experience ketosis or fat oxidation. When fat burned there are components that generate ketone cause bad breath. For health, most feel the side effects to the brain. Carbohydrates are the main food of the brain. If less carbohydrate, the brain can not work optimally, "he explained.
3. High Fat Diet Low Karbo
If you do the diet by reducing or eliminating one or more components of food, then you will mengasup other food components in larger numbers. This is a concept that must be understood so that you no longer get stuck in a diet program that gives the lure a slim body, but the physical damage in the long term.
The concept of this third fad diet will make you eat less food containing carbohydrates. A simple example, you reduce or even do not eat rice at all. However, that body does not limp, you will mengasup foods rich in fat and protein, for example, you only eat fish, meat, tempeh or tofu, eggs and other foods except rice, potatoes or bread that contains carbohydrates.
How was the body needs carbohydrates. If the intake is removed a number of risks such as osteoporosis can you experience in the future. "The content of calcium in the urine will increase. Foods high in protein acidic and cause the calcium out of bone so that the risk of osteoporosis," said Simpson.
He said the international medical journals do not prohibit this diet, but also not recommended. He mentioned the occupation Diet is one example of high-protein diet, but reduce or eliminate your intake of carbohydrates.
4. Very Low Calorie Diet
Diets like this are usually valid for obese patients with a doctor's supervision. This diet is aimed at weight loss in obese patients to the risk of surgery is reduced.
The concept of this diet is to reduce calorie intake by 800 kcal per day, with a record under the supervision of doctors and nutritionists. Typically, obese individuals who will perform the operation will consume only liquids, fruits, vegetables, carbohydrates and proteins are removed to reduce weight and ensure mengasup only 800 calories per day.
In patients with obesity, diet successfully lose weight for medical purposes. Unfortunately, the reasons for wanting to lose weight in an instant, many people on this diet and she did not suffer from obesity. As a result, the wrong diet causes adverse effects of calcium deficiency and death.
"Should this diet only for obese people tend to be as drastic weight loss, more than 1.5 kg per week," explained Miller.
