To put on weight, your body needs to take in more calories than it burns. Eating more calories increases weight. In turn, this surplus of food increases your waistline and your body mass index (BMI). It is easier to lose weight than to gain weight. It is also important to find your lean body mass after losing weight. 

Lean Body Mass - Calculator


Putting on weight raises your body mass Index (BMI). It also affects both your systolic blood pressure (SBP) and your diastolic blood pressure (DBP) simultaneously. You may also opt for a way to find your lean body mass to measure your body fat. Another key fact is that your blood pressure (BP) decreases significantly when you take off weight. A high BP is what you want to avoid like the plague.

High Blood Pressure the Silent Killer

High Blood Pressure damages your arteries by making them less elastic. As a result, pressure decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart causes chest pain called angina.

High Blood Pressure Symptoms 

Some people experience headaches, nosebleeds, or shortness of breath with high blood pressure. However, those symptoms, oftentimes, mimic many other things (serious or non-serious). Usually, these symptoms occur once blood pressure reaches a high level over a period of time. The good news – high blood pressure is reversible with a change in diet and lifestyle. 

If you don’t bring down your blood pressure, you put your life in harm’s way of developing a cardiovascular disease or something worse. High blood pressure brings with it major health challenges down the road. Journal of American Medical Association (JAMA). So, let’s try to keep your BMI at bay.

How to Figure Out Your Body Mass Index

To calculate your BMI, divide your weight in pounds by your height in inches squared, then multiply the results by a conversion factor of 703. For someone who is 5 feet 5 inches tall (65 inches) and weighs 150 pounds, the calculation would look like this: [150 ÷ (65) sq.] x 703 = 24.96.

Do you know what BMI range this is? Excellent. You are a quick learner.

Does BMI Change with Age?

BMI changes substantially with age. After about 1 year of age, BMI-for-age begins to decline, and it continues falling during the preschool years until it reaches a minimum around 4 to 6 years of age. Consequently, BMI-for-age begins a gradual increase through adolescence and most of the adulthood. BMIs for models, on the other hand, are minimal.

What BMI do Most Models Have?

  1. She is a healthy individual that takes care of herself.
  2. We got lucky genetically when it comes to fertility.
