Are you exercising to burn fat or to lose fat? If you're wondering whether there's a difference: Yes, there is. Let's quickly look at why these are two completely different processes.
Fat burning refers to the process in which the body uses fat as fuel for energy production. When we’re physically active, our body’s energy demand increases, and it taps into its stored fat reserves to provide the additional energy. This fat-burning process takes place in the mitochondria, the powerhouses of our cells that generate energy from nutrients. However, this has nothing to do with actual fat loss.
Fat loss, on the other hand, refers to the actual reduction of fat mass in the body. This loss can be achieved through a negative energy balance—meaning you consume fewer calories than you burn. A negative energy balance forces the body to use its fat reserves to make up for the energy deficit.
So, fat burning doesn’t automatically lead to fat loss unless a negative calorie balance is in place. Whether your body uses fat, protein, or carbohydrates as an energy source doesn’t directly affect fat loss. For weight loss, it’s always crucial to maintain a negative energy balance, forcing the body to use its energy reserves—which ultimately results in fat loss.
Oh, and don’t forget to get enough protein! During a diet, it’s important to provide your body with sufficient protein so it doesn't tap into your existing muscle reserves first. By the way, you can find all the information on losing weight here: Fat Loss Diet

Closing Words
So, to recap:
Fat burning = The body burns fat as an energy source.
Fat loss = The body actually loses fat mass.
Crucial for weight loss = Negative energy balance*
