Fat is NOT bad for you. Fat is a clean source of energy. In fact, the right fat is the cleanest source of energy for your body. Our bodies are designed to burn fat for energy and use protein for muscle building and structural maintenance.

In its natural state, when it hasn’t become accustomed to a sugar-filled diet, your body burns fat for energy. Energy comes from glucose. Your body breaks fat down into glucose slowly, through a process called gluconeogenesis. But if glucose is available to your body in a simpler, more direct form, it’ll go for that. Because it’s simpler and faster.

So what contains a lot of easy-to-access glucose? Take three guesses.

Sugar. Sugar has loads of glucose. When you eat sugar or other simple carbohydrates, your body gets an instant shot of glucose, and goes into super-energy mode.
