Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have a negative effect on health, leading to reduced life expectancy and/or increased health problems. Because obesity is a leading preventable cause of death worldwide, with increasing rates in adults and children, Authorities view it as one of the most serious public health problems of the 21st century. And in 2013, the American Medical Association classified obesity as a disease. Fat Reduction can be treated with Laser.
People are considered obese when their body mass index (BMI), (a measurement obtained by dividing a person’s weight by the square of the person’s height), exceeds 30 kg/m2.
Obesity is commonly caused by a combination of excessive food energy intake, lack of physical activity, and genetic susceptibility, although a few cases are caused primarily by genes, endocrine disorders, medications or psychiatric illness. Evidence to support the view that some obese people eat little yet gain weight due to a slow metabolism is limited. Excess fat is behind the reasons of Cellulite.
Obesity increases the likelihood of various diseases, particularly heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, osteoarthritis, gallstones, high blood pressure, high cholesterol and triglycerides, coronary artery disease (CAD), and stroke, among other conditions.
Obesity affects health depends on many things, including age, gender, where body fat, and physical activity varies. For example, fat accumulation around the stomach (apple-shaped) is more dangerous to have heart disease than fat accumulation around the hips (pear-shaped).
Eating healthy is a key to good health as well as maintaining a healthy weight. It’s not only what and how much we eat but also, we need to consider on how we eat.
Age, gender, body size, and level of physical activity dictate how many calories you need each day to lose weight or to stay at a healthy weight. Online calorie-needs calculators are a bit over-generous with their recommendations. And, in practice, it’s hard for people to track the amount of calories they take in each day.
A better approach: Adopt habits that will help you avoid overeating and skip some of the high-calorie, low-nutrient foods that are most strongly linked to weight gain, such as sugar-sweetened beverages, refined grains, and potatoes.
While it seems like skipping a meal is an easy way to cut calories, skipping breakfast usually backfires when hunger comes raging back mid-day, often leading to overeating.
Taking time to think about why and what you are actually eating is an easy way to avoid needless calories. Hungry? Make the healthiest food and drink choices as possible. Not really hungry? Choose something else to do or have a piece of fruit instead of a full meal. When you are eating, focus all of your senses on the food, so that you can truly enjoy what you are eating.
Slowing down at meals and choosing smaller portions can help avoid overeating by giving the brain time to tell the stomach when it’s had enough food. Limiting distractions—turning off the television, computer, or smartphone—can also help us focus on the food.
Fast food, restaurant meals, and other foods prepared away from home tend to have larger portions and be less nutritious than the foods we cook for ourselves.
Besides eating a healthy diet, nothing is more important to keep weight in check and staying healthy than regular activity. How much activity is recommended depends on whether you’re a child or an adult and what your goals are: good health or weight control. There are a lot of ways to get moving. Choose activities you enjoy. In addition to staying active, it’s important for all age groups to minimize “sit time” (sedentary time), especially time spent watching television.
For good health: 2.5 hours a week of moderate activity (brisk walking, slow bike riding) or 1.25 hours a week of vigorous activity (running, fast bike riding).
For weight control: 1 hour a day of moderate to vigorous activity. This activity can be pieced together from short bursts of 10 minutes or more.
Watching television (TV) can be enjoyable and informative; unfortunately it can also be double jeopardy when it comes to weight. It’s a completely sedentary activity that also seems to promote unhealthy eating habits though the ads, product placements, and other promotions that constantly pitch high-calorie, low-nutrient food and drinks. Try these tips for curbing exposure to TV and other screen media (video games, recreational computer use, and similar pastimes):
There is more and more evidence that a good night’s sleep is important to good health—and may also help keep weight in check. How much a person needs can vary a great deal, but there is good evidence that a lot of children and adults don’t get enough. Here are some general recommendations for sleep duration.
Today’s world is full of daily stresses. This is a normal part of life, but when these stresses become too much, they can take a toll on health and contribute to weight gain by leading to unhealthy eating and other unhealthy activities.
One of the best ways to control stress is also one of the best ways to combat weight gain: regular physical activity. Mind body approaches, such as breathing exercises, can also be beneficial.
