Weight and health

Acquiring and maintaining a healthy weight is essential for your health. As such it is important to keep a normal weight range rather than being over/underweight as both these can be harmful to your health as it predisposes you to diseases.  

There are few anthropometric measurements used to measure your weight. This is because one measurement alone is not sufficient to satisfy few factors playing a role in giving individual their weight. These factors include; 

  • age, 
  • muscle-fat ratio, 
  • height, 
  • sex, 
  • and body fat distribution, 
  • or body shape. 

As such two or three of the measurements can be used to determine if an individual fall in the healthy range;

Body mass index

This is calculated by taking the weight and dividing it with the person’s squared height. Moreover, the National Institutes of Health (NIH) gives a guideline on weight as follows; 

  • BMI< 18.5 means underweight.
  • BMI ranging between 18.5 and 24.9 means normal and healthy.
  • BMI ranging between 25 and 29.9 is overweight.
  • BMI over 30 indicates obesity. There are classes on this category. 

Waist circumference

This is another way used to measure your weight. This indicator is very important as having too much upper-body fat (where your vital organs are like heart, kidneys, etc) increase a risk of coronary heart diseases or cardiovascular disease, type 2 diabetes, high blood pressure, high cholesterol, etc. Thus the measurement says;

  • Women must have less than 38 inches
  • Men must have less than 40 inches 

Waist-to-hip ratio

This measure the ratio of your waist and hips to help you reduce the risk of cardiovascular disease. 

  • In male -Less than 0.9: 
  • In females- Less than 0.8: 

There are many other measurements used like the Body fat percentage, Waist-to-height ratio, etc. 

Gaining weight

Gaining weight is one of the less talked about areas because globally there is a significant increase of obesity which is the leading cause of non-communicable diseases. More importantly, people do not JUST lose weight, there is always a cause. 

It is thus important for those who are; not on a strict diet, not exercising, or doing things that potentially reduce your weight to consult if they lose a lot of weight in a short space. These could be an indication of underlying health problems like; 

  • having an over-active thyroid
  • eating unbalanced diet

  • depression problem
  • having pancreatitis
  • rheumatoid arthritis
  • having cancer
  • medications 

Moreover, there could be many other reasons leading to unexplainable weight-loss and as such, you should see your doctor. These should be the circumstances that could prompt you to wanting to enter a weight-gain diet. A person who already has a normal weight should be aiming to maintain the weight rather than gaining it.

Body building

Diet must play a major role for bodybuilders so they can use other enhancements as supplements to a healthy nutrient-dense food. This is because diets do not come with life-threatening risks like steroids and many other supplements which are available on the market. 

Furthermore, muscle is heavier than fat and as such, recent literatures suggest that the BMI can be adjusted (BMI between 25 to 29.9) to cater for the body builders and other trainers provided their waist circumference is within range; 

  • Women must have less than 38 inches
  • Men must have less than 40 inches
