fhutt1 - You've got some clarifying responses to your post. Note that the human metabolism either derives its energy from glucose or fat. When burning glucose, fat doesn't factor into the energy currency you're using at that time. To set off fat burning, eliminate exogenous glucose sources, meaning carbs, and your metabolism will start burning fat, a very healthy and clean way to fuel your body. You can still consume calories during fat burning, but when you consume carbs (sugar) in any form, your body favors glucose for energy, as it needs to manage it first to keep you healthy. This shuts off fat burning until you eliminate the sources of glucose. It's not hard to understand that us humans can easily alternate between glucose and fat burning depending on what we're eating and the length of time between meals. There is research emerging and confirming that being in regular (not necessarily constant) fat burning mode is very healthy on many fronts. Note that considering our standard dietary habits, there are many who have been primarily fueled by glucose without going into fat burning mode. This is the result of eating many meals and snacks per day. For these people, it takes a bit of time to transition into efficient fat burning mode. Once you do transition on a regular basis, it's far easier to readily alternate between the two. Your metabolism becomes "wired" to do this.

Here's a great thread about the recent research confirming ketone and fat burning health:
