Do you need to lose weight?
In Part 1 of this series you will see how to determine if you fit into the risk profile for complications of obesity. In Part 2, you will see the risks.
To lose or not lose weight? It depends not only on you weight and height, but on how much of the fat is around your abdomen. Fat around and inside the abdomen causes serious problems.
Here are the three steps to tell you if you are at risk and what you can do: 1. Your Body Mass Index(BMI) 30 2. Waist Circumference: women more than 35" - Men more than 40" 3. Risk factors: high blood pressure, diabetes, high cholesterol, If you answer yes to anyone of these you are at risk for heart disease,
See which fat distribution best fits you: Here are the three categories:
Obesity or Overweight? The differences : The first issue is the definition of obesity. Although I tell my patients that their ideal weight is the weight they feel comfortable with and the weight they can maintain without feeling anxious or deprived, everyone wants a number. We need to be careful here, because “ideal weight” based on fashion trends, celebrities’ physical appearance, or an idealistic body image rarely reflects healthy weight. Here are some of the guidelines to help you decide if you are just overweight or obese and at risk: NIH Guidelines on Weight Problems: In 1998, the National Institutes of Health correlated excess weight with different health problems and determined three guidelines for defining overweight and obese individuals. They use these three measurements: 1. Ratio of body weight to height (BMI), 2. Circumference of one’s waist, 3. Presence of risk factors related to heart disease
The ratio of body weight to height is called the body mass index (BMI), and reflects the total fat as related to one’s height. Find your height on the left side and follow the line until it intersects with the line representing your weight, as listed at the top:
Blue Zone: If your BMI is in the blue zone, you are underweight; 2. Circumference of the waist relates your obesity to significant medical problems: Clumped together, the fat cells just below the skin of the abdomen—surrounding all of the vital organs—are no larger than a bar of soap, but are the cause of all obesity-related medical problems. Since measuring the inner fat is difficult and expensive, researchers use the circumference of the waist as a good proxy since it correlates with the critical amount of inner fat responsible for the development of all of the complications related to obesity.
See a video of how your fat cells interact with your body.
Dr Annemarie Koster reports in the American Journal of Epidemiology in 2008: You Are At Risk if: 3. Risk factors and heart disease: "Burn" the fat- reduce the problems: The good news is that when one is losing weight, the fat deposited inside the abdomen is the first to be used and burned for fuel. However, the only way to start this process is by reducing the food intake or significantly increasing the amount of exercise (we are talking about daily hours of real working out in the gym) in order to create a calorie deficit. The decrease of just an inch or two in waist circumference corresponds to a relatively large reduction of fat in the abdomen, and consequently significantly reduces health complications caused by obesity.
Metabolic Syndrome = 3/5 risk factors + high BMI or high waist circumference:
About 15 years ago, scientists from medical schools at several universities began to notice an unusual group of health problems occurring together: hypertension, high cholesterol, high fat content in the blood, diabetes, and an unusual collection of fat around the waist (instead of being equally distributed over the body). This cluster of medical problems is known today as metabolic syndrome. 25% of Americans have Metabolic Syndrome:
More than 25 percent of the U.S. population has metabolic syndrome. Some researchers believe that if obesity continues to increase with no significant improvements, 80 to 90 percent of us will suffer from Metabolic Syndrome by the year 2030. Firs sign of Metabolic Syndrome can be a stroke or heart attack:
Very few complications of the Metabolic Syndrome can be detected before it’s too late. The first is often a heart attack or a stroke; other individuals will find out during a routine health evaluation that they have developed diabetes or hypertension. Metabolic Syndrome is caused by:
Consequently, similar to treatments for hypertension, diabetes, or high cholesterol, the first step for anyone needing to lose weight is to change their lifestyle.
Criteria for the Metabolic Syndrome: March 19, 2009 American Heart Association
Update
The following table shows you several of the many sets of criteria for the diagnosis of metabolic syndrome. Having three out of the seven criteria is sufficient to establish that you have the condition.
