As we age, our metabolism gradually slows down, and at this time, it is no longer just about the pursuit of physical beauty, but also for maintaining health and delaying aging.
After the age of 40, whether you've started experimenting** or not, fasting is a healthy way to lose weight worth trying. Today I will expand on it in detail.
One: What is fasting?
Intermittent fasting is a way to achieve weight loss by reducing calorie intake and time limiting the eating window. Compared to traditional dieting**, fasting focuses more on adjusting when and how you eat, rather than completely restricting the type and amount of food.
In general, fasting takes a time window of 8 hours, i.e. eating only during certain periods of time each day, such as 10 am to 6 pm. The rest of the time, drink only water, tea, or other sugar-free, low-calorie beverages.
Two: What is the principle of fasting?
The principle of weight loss based on fasting is based on two main factors: caloric restriction and autophagy.
1: Calorie restriction
By narrowing the window of time for eating, we can reduce our daily caloric intake. As a result, the body begins to burn stored fat for energy**, leading to weight loss.
2: Autophagy
Autophagy is a process by which cells repair themselves and remove metabolic waste. After entering a prolonged fasting state, the body activates the autophagy mechanism, which promotes metabolism and cell regeneration by breaking down and ** unwanted cellular components. Not only does this help to reduce fat accumulation, but it also helps to slow down aging and improve immunity.
Three: What is the effect of fasting?
Not only can fasting help you lose weight, but it also has many other health benefits.
1: Improves the body's insulin sensitivity
Since fasting reduces caloric intake, the body's need for insulin also decreases. This is very important for the prevention and control of type 2 diabetes.
2: Improves cardiovascular health
Studies have shown that by reducing body fat storage and regulating blood lipid and blood pressure levels, fasting can reduce the risk of diseases such as heart disease, high blood pressure, and high cholesterol.
3: Improves brain function
Studies have found that fasting can prompt the brain to produce a protein called BDNF, which plays an important role in enhancing memory, improving learning ability, and preventing cognitive deterioration.
4: Helps slow down aging
By stimulating the autophagy process, fasting is able to remove aging cells and promote the body's regeneration and repair, thereby improving quality, reducing wrinkles and blemishes, and making you look younger.
Four: Precautions for fasting
Despite the many benefits of fasting, it may not be suitable or detrimental to health for some populations.
First and foremost, pregnant women, lactating women, children, and adolescents should avoid attempting fasting because their bodies need more nutrients to grow and develop properly.
Second, people with serious illnesses or recovering should follow their doctor's advice and choose their weight loss method carefully.
Finally, if you have an eating disorder or are prone to binge eating, then fasting may not be right for you as it may exacerbate these problems.
