Deliberately skipping certain meals to eat better the rest of the time: that is the whole principle of intermittent fasting, an age-old practice back in the spotlight beyond the month of Ramadan alone. In practical terms, it means alternating stretches without food with a defined eating window — for example, eating only between 1 p.m. and 9 p.m. This simple method now appeals to athletes, entrepreneurs, artists and people of every age for its benefits to insulin sensitivity, energy and lasting weight loss.
What Is Intermittent Fasting?
Fasting and dieting are age-old practices. From Plato to Gandhi, by way of Pythagoras and Hippocrates, many influential figures and certain religions have already mentioned these practices in various forms throughout history. Outside the holy month of Ramadan, this approach somewhat faded over time in the rest of the world. But recently, its benefits and advantages have resurfaced thanks to what is known as intermittent fasting.
In fact, intermittent fasting is a simplified version of the fasting we already know. It should therefore not be tied to any spiritual or religious practice. The results and scientific studies, along with many testimonials, prove its effectiveness and confirm that the results are often remarkable!
This eating method has already won over many athletes, entrepreneurs, artists and citizens of every age and profession. It is a simple, effective eating habit that anyone could take up. It helps improve physical and mental health while contributing to weight loss in many people.
Why Adopt Intermittent Fasting Today?
So many of us want to free ourselves from our extra curves. We would all like, as far as possible, to live in good health, avoiding the diseases of modern civilization such as diabetes, cancers, heart disease and neurodegenerative diseases like Alzheimer's.
Our lifestyle, trying to keep up with that of consumer societies, has worked junk food into our daily lives. The abundance of addictive food rich in artificial flavorings and added sugars has disrupted good eating habits. Nowadays, we snack throughout the day. Our organs such as the liver, the pancreas and those of our digestive system are constantly called upon. This way of life affects not only our weight and vital organs, but also our brain.
How Does Intermittent Fasting Work?
Intermittent fasting consists of deliberately skipping certain meals and eating during a specific span of time, called the eating window. Its principle is very simple: you just deliberately alternate between stretches when you eat nothing and what are known as eating windows, when you can eat.
Practical examples:
| Eating pattern | Meals skipped |
|---|---|
| Eating every day between 1 p.m. and 9 p.m. | Breakfast |
| Not eating before 8 p.m., for one or two days a week | Breakfast and lunch, on the days concerned |
The Health Benefits of Intermittent Fasting
By adopting this method, you will gain many benefits:
- Better insulin sensitivity
- A more stable energy level
- The disappearance of cravings
- A rise in growth hormone
- An improvement in mood
- Lasting weight loss
- A slowing of ageing
- A better quality of life
The Impact on Calories and Weight Loss
By skipping meals, it becomes simpler to achieve an overall calorie deficit. In other words, losing weight and reducing body mass become easier. When we eat, the body spends a few hours breaking food down into nutrients during digestion. It must then carry the various substances obtained to where they need to go, taking care to store or eliminate the surplus.
The food consumed thus becomes our primary source of energy. Yet, during the intermittent fasting period, it is no longer available. Our body, needing to find energy to function properly, turns to the fat stored in fat cells to meet its needs. This is why exercising on an empty stomach is effective for losing weight. Having eaten nothing during the night, blood glucose levels are fairly low on waking. The body is forced to draw on its reserves.
Optimizing Insulin Through Intermittent Fasting
As soon as we eat, the body secretes a hormone called insulin. Its role is to manage what we take in as best as possible, transporting and storing it in our cells for when it is needed. So the more insulin the body produces, the harder it is to lose weight (because of insulin's storage role).
When fasting, the body becomes more sensitive to insulin. It therefore no longer needs to secrete much of it to metabolize food, which makes losing weight and gaining muscle easier. For example, a workout increases insulin sensitivity, thereby improving the body's efficiency. The nutrients taken in are carried to the muscles to aid recovery.
Conversely, people with insulin resistance have to secrete a great deal of it at every meal, even when the meals consist of small portions. These people are more likely to develop diabetes or to be overweight. Put simply, the more sensitive you are to insulin, the leaner and healthier you are.
Growth Hormone and Its Benefits
Insulin also hinders the production of growth hormone — known as somatotrophin, somatotropin or somatropin, GH for short. Fasting therefore helps increase its production. This hormone stimulates cell growth and reproduction. It thus allows the body to regenerate, but also to burn fat, build muscle, gain strength and fight ageing. It contributes to the proper functioning of the immune system, helps you sleep better and improves cognitive function.
The Effects on Cellular Renewal
The combination of these three factors allows the body to reach a new balance where it produces more antioxidants and initiates autophagy. The body rids itself more easily of damaged cells and is able to create new ones. This process slows the appearance and development of cancerous tumors. It also has anti-ageing benefits and helps avoid the risk of inflammation.
In this way, we get optimal value from our food. Intermittent fasting helps the body make better use of the food it consumes. It promotes both weight loss and muscle building (when done correctly).
Conclusion
Intermittent fasting aims to build new, healthy and lasting eating habits. This simple, effective method helps improve your physical and mental health while helping you reach your weight-loss goals. By adopting this approach, you give your body the chance to regenerate and to function at its best.
