NUTRITION

What is nutrition? conceptually different from the food nutrition.Food is everything we eat.
Nutrition is what is contained in these foods. you simply have to consume foods that have a balanced nutritional value needed by the body.
You need the nutrients that meet all the needs of your body, but with a low calorific value. Today, with the pattern of fast-paced life, people have a tendency to choose foods that are fast, which actually has nutritional value is very poor with an excessive amount of calories. Or also known as empty calories.
Logically one would think, to consume fewer calories means we need to eat less. And we will begin to air "diet" own style. The main problem of the diet is to eat less at the same time with reduced food consumption, you also reduce the value of nutrients that go into yourself.
When you reduce the nutrients entering your body, your body will experience a nutritional deficiency. This situation is actually slowing down your metabolism. If this condition continues, you will feel tired or lethargic, and prone to stress. And if it continues longer, your body will experience a break-down. Usually you will experience problems with your health. Can be in the form of digestive disorders like ulcers, etc..
When you have problems with health, you will tend to return to normal eating. The tendency is that you would normally eat with food portions larger than before the diet (known as "revenge". The result you'll get fat again. This is the reason why a lot of people who have diets YO-YO. Fall but then rise again. And when you will fatten your back on a diet again. The process continues like a circle that never ends.
On a diet by not eating or fasting is the way the worst in the history of weight loss.
So, how can you find food with low calories but full of nutrients that your body needs? Almost Impossible! One solution is to use supplementation.
This is why use a nutrition program from Herbalife ShapeWorks.The program is very simple to use even for people who have a busy lifestyle.
Next decide whether you're ready to start this program?
DEFINITIONS Obesity Obesity is excess body weight as a result of excessive accumulation of body fat.
Everyone needs some body fat to store energy as heat insulation, shock absorber and other functions. The average woman has more body fat than men. Comparison between normal-weight body fat is around 25-30% in women and 18-23% in men. Women with more body fat than 30% body fat and men with more than 25% are considered obese.
Someone who has a weight 20% higher than the mean range of normal weight is considered obese. Obesity is classified into 3 groups:
1. Mild obesity: overweight 20-40%
2. Obesity is: 41-100% overweight
3. Severe obesity: excess body weight> 100%. Severe obesity was found as much as 5% of the people who are obese.
Attention is not only directed against the amount of fat deposited, but also to the location of body fat accumulation. The pattern of distribution of body fat in men and women tend to be different. Women tend to store up fat in the hips and buttocks, thus providing a picture of like a pear. While the men usually hoard fat around the abdomen, thus providing a picture of the apple. But it is not something absolute; sometimes in some men looked like a pear and some women look like apples, especially after menopause.
Someone who buried a lot of fat in the stomach may be more susceptible to various health problems associated with obesity.They have a higher risk. Pears better picture than the picture of an apple.
To distinguish the two images, has found a way to determine whether a person is shaped like an apple or pear, namely by calculating the ratio of waist to hip. Waist is measured at the narrowest point, while the hip was measured at the widest point; and waist size divided by hip size. A woman with a waist size of 87.5 cm and 115 cm hip size, has a waist-hip ratio of 0.76. Women with pingganginggul ratio of more than 0.8 or men with a ratio of more than 1 pingganginggul, said the apple-shaped.
CAUSE Scientifically, obesity is caused by consuming more calories than needed by the body. The cause of the imbalance between calorie intake and burning is still unclear.
The occurrence of obesity involves several factors:
1. Genetic factors. Obesity tends to run, so it is thought to have genetic causes. But family members not only share genes but also diet and lifestyle habits, which could encourage obesity. Often it is difficult to separate lifestyle factors with genetic factors. Recent studies show that the average genetic factors influence 33% of a person's weight.
2. Environmental factors. The gene is an important factor in many cases of obesity, but a person's environment also plays a significant role. This environment includes behavioral / lifestyle patterns (eg what to eat and how many times a person eats and how their activities). A person certainly can not change their genetic pattern, but he can change the diet and activity.
3. Psychological factors. What's inside a person's mind can affect eating habits. Many people react to her emotions by eating.
One form of emotional distress is a negative self-perception. This disorder is a serious problem with many young women who suffer from obesity, and can cause excessive awareness about obesity and discomfort in social intercourse.
There are two abnormal eating patterns that could be the cause of obesity is eating in a number of very much (binge) and eat at night (at night eating syndrome). Both diets are usually triggered by stress and disappointment.Binge similar to bulimia nervosa, in which a person eats in a number of very much, the difference in binge this is not followed by spewing back what has been eaten. As a result, the calories consumed very much. On the night eating syndrome, is the reduced appetite in the morning and followed by excessive eating, agitation and insomnia at night. 4. Health factors. Several diseases can lead to obesity, including: - Hypothyroidism - Cushing's syndrome - Prader-Willi Syndrome - Several neurological disorders that can cause a person to eat a lot. 5. Drugs. Certain medications (eg steroids and some anti-depressants) can cause weight gain. 6. Developmental factors. The addition of size or number of fat cells (or both) cause increasing amounts of fat stored in the body. Obese people, especially those that became obese in childhood, can have fat cells sampak 5 times more than people whose weight is normal. The number of fat cells can not be reduced, so weight loss can only be done by reducing the amount of fat in each cell. 7. Physical activity. Lack of physical activity is probably one of the main causes of increasing incidence of obesity in a society that is prosperous. People who do not actively require fewer calories. Someone who tend to consume foods rich in fat and not doing physical activity are balanced, will be obese.
SYMPTOMS Excessive accumulation of fat below the diaphragm and the chest wall can suppress the lungs, causing breathing problems and shortness of breath, even if the patient is only a mild activity.
Respiratory problems can occur during sleep and causes cessation of breathing for a while (sleep apneu), so during the day people often feel sleepy.
Obesity can cause a variety of orthopedic problems, including lower back pain and aggravate osteoarthritis (especially in the hip, knee and ankle khaki).
Often found skin disorders. A person who is obese has a body surface is relatively narrow compared with the weight, so body heat can not be disposed of in an efficient and sweat more.
Often found edema (swelling due to accumulation of fluid) in the leg and wrist khaki.
COMPLICATIONS
Obesity is not only pleasing to the eye but it is a terrible health dilemma. Obesity is directly harmful to one's health. Obesity increases the risk of some chronic diseases such as: - Diabetes type 2 (arising in adolescence) - High blood pressure (hypertension) - Stroke - Heart attack (myocardial infarction) - Heart failure - Cancer (certain types of cancer such as prostate cancer and colon cancer) - Gall bladder stones and bladder stones - Gout and gouty arthritis - Osteoarthritis - Sleep apneu (failure to breathe normally while sleeping, causing reduced blood oxygen levels) - Pickwickian syndrome (obesity accompanied by facial redness, underventilasi and drowsiness).
DIAGNOSIS Measuring body fat.
Not easy to measure a person's body fat. Following methods require special equipment and is performed by trained personnel:
1. Underwater weight, body weight measurements performed in water and then body fat is calculated based on the amount of water remaining.
2. BOD POD is an egg-shaped space that has been computerized. Once a person enters the BOD POD, the remaining amount of air used to measure body fat.
3. DEXA (dual energy X-ray absorptiometry), resembling bone skening. X-rays are used to determine the number and location of body fat.
following ways more simple and uncomplicated:
1. Duration of skin, skin fold thickness in several parts of the body is measured by the term (an instrument that resembles metal forceps).
2. Bioelectric impedance analysis (analysis bioelektrik prisoners), the patient stands on a special scale and a number of harmless electrical current is passed through the body and then analyzed.
The examination could give incorrect results if not done by experts.
Choosing a weight loss program is safe and successful.
The elements that must be considered in choosing a weight loss program:
1. Diet should be safe and meet all of the recommended daily requirements (vitamins, minerals and proteins). Diet to lose weight should be low in calories. 2. Weight-loss program should be directed to the weight slowly and steady. 3. Before a weight loss program begins, a thorough medical examination. 4. Programs that follow should include weight maintenance after weight loss is achieved. Weight maintenance is the hardest part of weight control. Courses selected must include changes in eating habits and physical activity is permanent, to change lifestyles in the past contribute to the occurrence of weight gain. The program must conduct behavior change including education in healthy eating habits and long-term plan to address weight problems.
Obesity is a chronic condition (chronic). Obesity is often considered a temporary condition that can be resolved for several months with a strict diet. Weight control is a long term business. To be safe and effective, any weight loss program should be aimed at long-term approach.
Surgery should only be performed in severe obesity. In general, this surgery is safe and efficient.
