Hello Interloper!

The correct answer is fat cells get smaller!
If you don’t understand what happens to fat cells when you lose weight you are not alone.
They surveyed 855 people and 73% of them could not identify what actually happens to fat cells when you lose weight.
Misunderstanding some fundamental basics of how fat cells work means we expect ourselves to be able to shift stubborn fat and lose weight easily without thinking about the biological facts.
The Science Behind Stubborn Fat, What Happens to Fat When You Lose Weight?
The process of losing fat from your fat cells is called lipolysis. When you lose weight you don’t destroy fat cells, instead the fat cells shrink.
Imagine a fat cell as a beach ball – if you only fill it up with a little bit of air, the ball will stay small. If you blow in a lot of air it will expand. Fat cells work like this, adjusting to the amount of energy that your body creates in the form of fat.
When your body needs energy it sends out signals to your fat cells to release this energy via hormones. When the fat cell receives the message from the hormones, triaglycerol (the scientific name for the fat in your cells) is released into the blood stream to be transported to the muscles and organs that need the energy.
If your body isn’t getting all of this energy from your food, then it calls on your fat reserves.
Why Is Some Fat More Stubborn Than Other Fat? Not all fat cells are not created equal.
The part of the fat cell that receives the hormone message to release fat is known as a receptor. There are different types of receptors at work in fat cells. In simple terms, beta receptors are better at releasing fat than alpha receptors. Fat cells around the hips, stomach and thighs have a higher density of alpha receptors than other fat cells, the exact areas where most people have stubborn fat.
So the physiology of these cells means it is much harder to actually shift that fat.
The exercise and food choices you are making may well be triggering the right hormones to tell these fat cells to release triacylglycerol, but the receptors receiving the message aren’t very good at hearing it.
This is why exercising and healthy eating can get you so far, but why some areas just seem to stay the same size. This doesn’t mean it is impossible to lose that stubborn fat! So, what are the options?
