If we want to be healthier and have a more toned figure, it can be useful to know when, exactly, our body begins to burn fat. But between contradictory advice and preconceived ideas, it is easy to get lost in the maze of information on the weightloss and exercise. Together we are interested in determining the precise moment when our body begins to burn fat. The good news ? A healthy and balanced lifestyle is within reach.
Weight loss: how long should my sports session last?
First of all, let’s understand the process. When we train, our body uses different energy sources to fuel our muscles:
At first, it uses proteins (in a very short effort, of a few seconds), then it draws on carbohydrates stored in the form of glycogen, once these reserves are exhausted, the body turns to fats to obtain its fuel. .
So the question is how long does it take? Well, the answer is simple: it depends! Indeed, if you have not trained, it can take 45 minutes whereas if you are an experienced athlete, the majority of fats can be used from 15 minutes (the body being used to the efforts long term). So there would be no reference duration for all? Actually, yes.
What if 20 minutes was enough?
As soon as we step on the treadmill or get on our bike, our body begins to burn fat, even if it’s at a modest rate at first. However, the real question lies in the key moment of physical activity where we switch to a predominant burning of fats compared to carbohydrates. This turning point would take place After environ 20 minutes, just enough time for a complete warm-up. This is when our body typically switches to burning fat as its primary source of energy. Furthermore, beyond precise timing, the key is to aim to expend a higher percentage of calories from fat. This objective can in particular be achieved by practicing an aerobic activity for around twenty minutes, which corresponds to a sustained effort but of low to moderate intensity.
Favor duration rather than intensity to burn fat
Research carried out by scientists at the Stanford University School of Medicine (United States) looked at the amount of time you need to spend in the gym to successfully burn fat. Their conclusions? An intense effort of just 10 minutes is enough to start burning body fat, although in a rather moderate way. For what ? Because’we must favor duration rather than intensity. So it is better to favor moderate effort over the long term…rather than intense short-term effort. The objective? Go beyond 20 to 30 minutes of moderate to intense exercise to start drawing on fat and, therefore, favor an endurance sport that we will be able to practice in the long term such as:
Walking Running Cycling Swimming Aquabiking Sports in series/intervals/with interval training…
On vise environ 20 to 30 minutes of moderate to intense exercise. But above all, we find activities that we enjoy and that motivate us to move regularly. This is where the real key to a healthy and balanced lifestyle lies!
