There are three primary factors that control how quickly you lose fat from specific parts of your body:⁣⁣
⁣⁣
1. How fat cells respond to catecholamines.⁣⁣
2. How fat cells respond to insulin.⁣⁣
3. How much blood flow an area of fat cells receive.⁣⁣
⁣⁣
We’ve seen the first step in yesterday’s post (go check it out if you haven’t!)⁣

But basically..⁣
⁣⁣
Fat cells have two types of catecholamine receptors: alpha-2 and beta-2. Each receptor behaves differently when it gets a signal from a catecholamine. Beta-2 receptors tell cells to release more fat. On the other hand, alpha-2 receptors tell your cells to stop releasing fat.⁣⁣
⁣⁣
When a fat cell has more alpha-2 receptors than beta-2 receptors, it releases fat slower than other cells. When your brain senses that it has enough energy from other cells, it tells fat cells to stop releasing their energy. By the time this happens, these “stubborn fat cells” have barely released any fat.⁣⁣
⁣⁣
These stubborn cells tend to congregate in the same areas on your body.(16) For example, fat cells from the stomach tend to be about 10-20 times more responsive to catecholamines than fat cells from the glutes.(17)⁣⁣
⁣⁣
Fat cells can also respond differently to the effects of the hormone insulin, another kind of signaling molecule. Insulin is generally considered a “storage hormone,” meaning it helps nutrients like fat enter cells. When insulin levels are high fat burning usually drops to zero, and vice versa.(18)⁣⁣
⁣⁣
Some kinds of fat, like visceral fat, are more insulin resistant than others. They keep releasing fat despite insulin being present.(19) On the other hand, stubborn fat tends to stop releasing triglycerides in response to insulin.⁣⁣
⁣⁣
The amount of blood flow to different parts of your body also determines how much fat you lose. Areas that receive more blood flow generally lose fat easier.(20)⁣⁣
⁣⁣
Lower body fat in both males and females has about 67% less blood flow, and has 87% less hormone sensitive lipase activity (HSL).(21) HSL is an enzyme that helps release fat from cells — for our purposes, it’s good.(22)⁣⁣
⁣⁣
