MYTH: Carbohydrate Drives Insulin, Which Drives Fat Storage FACT: Your Body Can Synthesize and Store Fat Even When Insulin Is Low One of the biggest misconceptions regarding insulin is that it’s needed for fat storage. It isn’t. Your body has ways to store and retain fat even when insulin is low. For example, there is an enzyme in your fat cells called hormone-sensitive lipase (HSL). HSL helps break down fat. Insulin suppresses the activity of HSL, and thus suppresses the breakdown of fat. This has caused people to point fingers at carbohydrate for causing fat gain. However, fat will also suppress HSL even when insulin levels are low. This means you will be unable to lose fat even when carbohydrate intake is low, if you are overeating on calories. If you ate no carbohydrate but 5,000 calories of fat, you would still be unable to lose fat even though insulin would not be elevated. This would be because the high fat intake would suppress HSL. This also means that, if you’re on a low carbohydrate diet, you still need to eat less calories than you expend to lose weight.
