What are the different types of fat?

You can think about the fat in three pools. There’s something called ‘brown fat’; babies have more of this and this is the fat that allows you to shiver and helps maintain your body temperature. As we get older, we use most of the brown fat, but the brown fat is actually good for us. The rest of us have fat. We can think about that in two places. So there’s body fat; that’s the fat that is under your skin, the subcutaneous fat, so around your face, under your neck, in the folds of your arms and in your legs, and that appears as cellulite. Then there’s the fat that’s around the organs, so it’s on the inside and surrounds the heart, the lungs, the liver, the kidneys, and is called visceral fat. If you had to find a real villain, it’s the visceral fat. That’s the one that’s really causing a lot of problems and is metabolically active and releasing all of these inflammatory markers. That’s the one that’s really hard to lose.
