Belly Fat 101

What is Belly Fat


 

Two Types of Fat




Subcutaneous Fat - is the soft and jiggly fat that can be pinched and visible under the skin. Most of our body consist of this soft fat and acts as insulation, it provides energy for daily activities and produces helpful molecules to help maintain weight.


Visceral Fat (Intra abdominal fat) - it's the hard fat that is deep in your abdominal cavity and surrounds your organs and is beneath your muscles. This is what makes your belly look distended, such as the "beer belly" look.

This deeper fat is far more dangerous than the soft fat because it produces a large number of molecules that may cause harmful effects such as:

  • high blood pressure

  • increased cholesterol levels

  • heart disease

  • type 2 diabetes

  • certain cancers

  • insulin resistance

  • leptin resistance

Belly Fat Culprits


1. In general, a Sedentary Lifestyle and Poor Nutritional Choices are the main causes of obesity. When you eat more, especially processed foods and sugars (empty calories),than you burn off, you will gain the weight including inches all over, especially around your belly. The American Journal of Medicine reports substantial increases in weight and waist circumference in both men and women as physical activity decreased over a 22-year span.



2. Age, Sex, Genetics

  • Age - as you get older, the natural process is losing muscle mass, especially for those who are inactive and don't do physical activities. And as you lose the muscle, you also slow down your metabolism. Therefore, you're unable to burn as many calories. In this state, it's harder to keep in check with your weight as well as keeping the fat off.

  • Sex - Women may notice an increase around their middle, even if they're at their healthy weight, because of menopause. Also, when there is a decrease in estrogen production, the belly fat accumulates.
