Does Exercise increase fat loss?

BUILDING MUSCLE AND BURNING FAT – IS IT POSSIBLE?

In Part 1 I explained the process of burning fat and fat synthesis. Today, let’s answer the question: Does exercise increase fat loss?

PRIMARY SOURCES OF ENERGY DURING EXERCISE

The primary source of fuel during exercise is carbohydrates.

In comparison to protein and fat, they are easy to break down and don’t burn as many calories. Carbohydrates stored in our muscles and liver are the first to be used during exercise lasting between 1-20 minutes.

It does not take long until the stored glycogen is all used up, especially if exercise intensity is high. Thus, the body needs to begin using fat as fuel to get ATP (energy equivalent in our body).

Protein is not used as fuel during exercise, as it takes too long to break down and burns many calories as well. The only exception is if you have been starving and your body does not have enough stored glycogen or free fatty acids to use as fuel. This is why I don’t recommend training fasted!
