Burning fat, just like the entire metabolism, is a fairly complex process. However, it is worth learning about some of its aspects to know what is happening in our body when exercising and how is it possible that physical activity is the best way to get a nice figure.
We all know that food provides the energy that is necessary to keep us alive. Yet, the process of energy production remains a secret. It would be ideal if the body preferred to first use its fat reserves, which it accumulates to supply us, among others, with energy. But the body first reaches for carbohydrates because these compounds are available to all tissues, unlike the fatty acids. For this reason, when exercising, it is the carbohydrates that are burnt first, and then goes the fat. It is estimated that during the first twenty minutes of aerobic exercises our body burns 80% of carbohydrates and 20% of fat. If we want our exercise to bring about a decrease in the fat tissue, then we must exercise for more than twenty minutes regularly. Between the twentieth and the fortieth minute of the workout, 50% of energy comes from carbohydrates and the other 50% from fat. Later on, 80% of energy comes from fat. Therefore, it is best when we exercise for about 60 minutes at a time.
The metabolism of fatty acids increases not only during exercising but also over the next 48 hours thereafter. It is so because of the lower production of insulin and it is this hormone which contributes to accumulating fat tissue. Hence, if we want to take off weight and bur the excess of fat tissue, we should exercise sixty minutes a day three times a week and eat healthy diet in between.
