Using More Fat for Energy Doesn't Mean More Fat loss!
Let’s start with some basics of energy metabolism. Just like any other system, our body needs the energy to survive and we derive this energy from the food. Now, all the 3 macronutrients- proteins, carbohydrates and fats contain energy and our body can efficiently use all these 3 to produce energy but the important point is that the ratio in which these macronutrients are oxidised keeps changing depending on several factors like type and duration of the activity, diet, gender, age etc. In fact in women this ratio changes throughout the month. Now the fat loss is independent of which macronutrient you are burning to produce energy. In fact, there are several supplements in the market that promise to make you lean by shifting your body to “fat burning mode”. But the total fat loss/gain only depends upon the total calories and protein in the diet. You might be burning more fat without losing even a gram of fat. For example, when you are on a low carb or a ketogenic diet, your body uses fat as its primary source of energy. But you can still gain fat if the calories are not controlled. Conclusion: Fat loss is independent of which fuel you are using to produce energy. The most important factors for fat loss are your caloric and protein intake along with the energy expenditure throughout the day.
