I admire you guys' knowledge of this stuff, but for the love of god, could you please just say things as simple or layman as possible. I am not knocking it, but I feel sometimes when a question is asked, by the time myself and the not so knowledgeable others are finished reading the response, we are more confused than before. Like I said no disrespect meant, just speaking out for the ones who chose not to.
I will try to brake it down as much as possible:
4 calories per 1 gram in protein 4 calories per 1 gram carbohydrate. 9 calories in 1 gram fat.
It takes more time to burn fat, so if you want to burn fat faster you need fuel.
When the body is in resting state it's using 100% fuel from fats and 0% carbs.
When you are jogging 66% Fats 33% carbs. Sprinting 16% fats, 84% carbs. Think of your body as an engine, the hotter you run the more fuel you use. This is called the (law of thermodynamics) When your body tries to cool itself from an exercise there is an elevation of the body's metabolism.
Remember, it is not how much fat an individual burns that dictates body fat reduction. Instead it is how many calories are burned. That's what I mean by " fat burns in a carbohydrate flame." Maximal fat burning cannot occur without sufficient carbohydrate to continue.
Have you ever noticed why marathon runners drink so much Gatorade throughout the race? Without the carb drinks they will hit what's called "runner's wall". When this happends the body has run out of fuel and cannot convert their fat for energy fast enough.
You will see them drop like fly's.
Another example, I was reading about a guy that swam across some crazy distance over some ocean channel that took a day to complete. The way he was able to do it was he stored a bunch a fat then (Remember more calories in fat) As he swam he consumed high carb drinks throwout the day. By the time he was finished most of the fat was gone. If he did not consume the carbs most likely he would have hit a "wall" within a couple hours. How many calories do you think he burnt?
The goal is not to use protein as the energy source, but the carbohdrate as the main source. Your body would rather cannibalize itself rather than give up it's fat. Our body is programed this way for survival. Protein should be dedicated for growing and maintenance of muscle. The more muscle you have the more calories they burn. When choosing a diet make sure your not striping your carbs too much, but focus on the calories consumed. For me I like the 30%fat 40%Carb 30%Protein.
I hope this makes it clearer for you. Good luck
