The number of obese and overweight people is increasing dramatically all over the world. USA was the first country to notice its people were getting fatter and fatter. Nutritionists and health experts say the main reason is diet and physical inactivity.

Weighing the Cost of Obesity

Weighing the Cost of ObesityBody mass index, or BMI, is a new term to most people. Body mass index (BMI) is a measure of body fat based on height and weight that applies to both adult men and women. BMI uses a mathematical formula that takes into account both a person's height and weight. It equals a person's weight in kilograms divided by height in meters squared, hence, the formula: BMI=kg/m2. It is designed for men and women over the age of 18. A healthy BMI is between 20 and 25. A result below 20 indicates that one may be underweight; a figure above 25 indicates that a person may be overweight. BMI is also the measurement of choice for many physicians and researchers studying obesity. Obesity is now considered an epidemic in the United States. More than half of Americans are overweight including at least one in five children being above the normal weight for their age. Nearly one third of Americans are obese. Obesity is on the rise because food is abundant and physical activity is optional or less than what is required to maintain one's health. The number of obese and overweight people is increasing dramatically all over the world. The USA was the first country to notice its people were getting fatter and fatter. Canada followed, then Australia and Western Europe, and now the rest of the world. Nutritionists and health experts say the main reason for the increase in weight problems is having a poor diet and physical inactivity. Each year, Americans spend billions of dollars on dieting, diet foods, diet books, diet pills, and the like. Another $45 billion is spent on treating the diseases associated with obesity. Furthermore, businesses suffer an estimated $20 billion loss in productivity each year from absence due to illness caused by obesity.Although there are genetic and hormonal influences on body weight, excess weight is a result of an imbalance of calories consumed versus calories burned through physical activity. If you consume more calories than you expend through exercise and daily activities, you gain weight. Your body stores calories that you don't need for energy as fat.The following factors, usually working in combination, can contribute to weight gain and obesity:Diet. Regular consumption of high-calorie foods, such as fast foods, or increasing their portion sizes contributes to weight gain. High-fat foods are dense in calories. Loading up on soft drinks, candy and desserts also promotes weight gain. Foods and beverages like these are high in sugar and calories. In general, eating away from home also increases calorie intake since the tendency of people is to eat at fasfood joints whenever they are outside the home.Quitting smoking. Smokers tend to gain weight after quitting. This weight gain may be partially due to nicotine's ability to raise the rate at which your body burns calories (metabolic rate). When smokers stop, they burn fewer calories. Smoking also affects taste since quitting smoking makes food taste and smell better. Former smokers often gain weight because they eat more after they quit. However, cigarette smoking is still considered a greater threat to your health than is extra weight.Pregnancy. During pregnancy a woman's weight necessarily increases. Some women find this weight difficult to lose after the baby is born. This weight gain may contribute to the development of obesity in women.Certain medications. Corticosteroids treatment have shown an increase in fat and in weight presenting obesity. Some antidepressant medications can also lead to weight gain. So thus some high blood pressure and antipsychotic medications.Sedentary lifestyle is also one of the principal causes for obesity. It has been proven that physical activity is one of the greatest factors in the body's use of energy. The increase in physical activity allows the intake of more calories and helps a person achieve a more favorable caloric balance in the body. Very often, weight loss medications for treating obesity are prescribed with minimal or no lifestyle modification. Researchers believe this practice limits their therapeutic potential. They also say that these drugs are more effective when combined with a lifestyle program of diet and exercise.

Effectively Managing Morning Sickness

Effectively Managing Morning Sickness

Many pregnant women suffering from morning sickness may be wondering why it happens and whether it serves a purpose. When nausea and vomiting occur, they are often an indication of elevated hormonal levels, which is a sign that the pregnancy is in progress. However, it doesnt mean that pregnant women who do not experience "morning sickness" are more likely to have a miscarriage.This condition, according to traditional Chinese medicine, is a result of toxins that overburden the liver, hindering its ability to process the high levels of pregnancy hormones. Imbalance in the liver can cause nausea and vomiting. Whatever the reasons may be, the odds of having morning sickness are greater if you:experience nausea as a side effect of birth controlsuffer from motion sicknesshave female relatives who also experienced morning sicknessare pregnant with twins Morning sickness usually lasts throughout the first trimester. To be relieved from its hassle and inconvenience, a combination of lifestyle and dietary changes as well as some alternative approaches should be tried by the expecting woman.Simply follow the slow, steady rule when eating. It is better to eat six small meals spread throughout the day than consume three large meals. Dont let yourself get hungry because the rise and fall in blood sugar can only add to your queasiness. Having gone without food for quite a while is the reason why many women feel nauseated in the morning. To avoid having an empty stomach, nibble on bland foods such as dry toast and saltine crackers. It is advisable if you can keep a box of crackers at your bedside to munch on before getting up in the morning.Passing up foods that have strong odors and refraining from eating greasy or spicy foods help prevent morning sickness. It is also important for the pregnant woman to drink lots of water and to take prenatal vitamins.If you still experience nausea after giving your best efforts to avoid it, try cold foods which can be soothing, especially water-rich choices such as melons, grapes, berries, fruit smoothies, cucumbers and oranges. Eating any form of citrus alleviates nausea. Sniffing on a slice of lemon can help also relieve morning sickness. Another great antidote for morning sickness is ginger which comes in different forms such as fresh ginger, ginger powder, dried ginger tablet or capsules, ginger ale, ginger snaps, and ginger tea.Pregnant women experiencing morning sickness should always remember that staying hydrated is essential to replenish lost electrolytes, the minerals such as sodium and potassium that regulate the fluid balance in the body. Take slow, steady sips when you drink anything. Taking in more than 2 ounces at a time tend to bypass the tissues and fluids travel directly to kidneys and bladder.When morning sickness starts to interfere with a womans quality of life, doctors may recommend vitamin B6 supplements which are easily depleted and absorbed by the body when pregnant. Thats why it is important to take a supplement or to load up on food sources that contain B6 such as egg yolks, yoghurt and whole grains to help alleviate [*_*].
