Being overweight or obese can increase the chances of high triglycerides & LDL, and low HDL. In addition, it can lead to high pressure, diabetes, heart disease, and other health problems. Having excess weight around the waist, may be likely to develop the metabolic syndrome.
If overweight and have high cholesterol, may need to get the LDL and the weight under control by changing the diet and increasing physical activity. At the start of the TLC program, the focus will be on lowering LDL toward the goal level by making changes such as reducing saturated fat and calories and increasing fiber, which could also, helps to lose weight.
After about two to three months of TLC, if still overweight, then may need to focus additional attention on losing weight as the approach to LDL goal, especially if have the metabolic syndrome.
Body mass index
The Body Mass Index or Quetelet index is a statistical measure of body weight based on a person's height. It is easy to measure and calculate, so most widely used tool to identify weight problems, such as underweight, overweight or obese. The Belgian polymath Adolphe Quetelet between1830 and 1850 invented it.
BMI calculation formula
BMI calculation formula in SI units
BMI = mass in kg divided by the square of height in meters.
BMI calculation formula in Imperial units
BMI = mass in lb multiply by 703 divided by the square of height in inches.
Or
BMI = mass in lb multiply by 4.88 divided by the square of height in feet.
Cholesterol BMI relationship
Studies on the relationship between body mass index and serum cholesterol shows a significant, direct association of BMI and total cholesterol and LDL-cholesterol in men. HDL-cholesterol was inversely relating to BMI in both sexes. Sex differences in the association of BMI with total cholesterol, and LDL-cholesterol, may account for the lower risk for CHD in women compared with men of similar BMI.

Healthy body mass index (BMI)
- Normal weight: BMI = 18.5–24.9
- Overweight: BMI = 25–29.9
- Obese: BMI = 30 or greater
Healthy waist size
A waist measurement of 35 inches (40 inches for men) or more for women is one of the factors involved in the metabolic syndrome. It also indicates an increased risk of obesity-related conditions, such as heart disease.
Many health experts are even more stringent, recommending a target of 30 inches or less for a woman and 35 for a man.
How do you measure Waistline?
Here is the procedure to measure one's waistline size.
- Have a measuring tape.
- Upper garment covering the waist should be removed, or at least hold it up with the hands.
- The exact waistline can easily identify; it is just a ½ inch above the bellybutton (navel).
- Measuring tape should be hold just above the navel and wrap around the body. Confirm that the tape runs a perfect circle around the waist without sag in between.
- During measurement, do not pull the stomach in and be relaxed.
- Note down the number that ends on near the start point of the tape that is the waist size measurement.
