To understand why it’s so dang hard to get certain areas of your body lean, you need to understand how and why fat is stored and mobilized.
When you eat food, your body breaks it down into various substances, one of which is glucose, or blood sugar.
Your body also releases the hormone insulin, which tells your liver, muscles, and fat tissue to take the glucose from the blood and store it.
Your liver and muscles store the glucose as a substance known as glycogen, and your fat cells store it as as a substance known as triglycerides.
The storage of glycogen expands the size of the muscle cells, and the storage of triglycerides expands the fat cells, which in turn expands your waistline.
