Similar : Losing weight involves fat burning, as well as other fuels as part of metabolic processes known as anabolism, that builds muscle, bone, blood cells, nervous tissue, etc., and catabolism, that breaks down and regenerates body tissues. Both processes require fuel, and burning fat for calories is how we get energy, as well as lose weight. It's all about energy balances

Great Question !!!: Technically the fuel you burn depends on intensity of activity and how long from your last meal. Sugar or carbohydrates are the preferred fuel source by most of your body and therefore used first. The More vigorous the activity and longer between meals the more fat burns. However your tissues are constantly re-balancing your calorie stores, so over time all calories expended are the same
