The Intermittent Fasting
Intermittent fasting ” (IA) has become popular within the fitness and nutritional industry . and Intermittent fasting can be defined as a voluntary abstinence from food and drink for specific and recurring periods. Therefore, It is important to determine what type of fast we are referring to.
In intermittent fasting, the patient’s participation is voluntary. That is, AI should not be confused with starvation, a state of chronic nutritional deficiency
The AI is a strategy that intersperses cycles, with periods of fasting and feeding that vary according to objectives and according to the type of fast. This model tries to focus on reducing calories for hours, even days, with the aim of unleashing a series of physiological adaptations that influence the improvement of health and body composition.
How does intermittent fasting work?
The mechanics of this method, is fairly simple and common sense. It happens that when between meals, as long as we don’t eat snacks, our insulin levels drop and our fat cells manage to release stored sugar to use as energy. In fact, people lose weight if we let our insulin levels drop . Hence, the whole idea of intermittent fasting is to allow insulin levels to drop low enough and for long enough for us to burn our fat.
This model based on the fact that during periods of fasting, triglycerides are broken down into fatty acids and glycerol, which are used for energy. therefore, The liver changes fatty acids to ketone bodies, which provide a main energy source for many tissues during fasting, especially the brain. And also, Ketone levels begin to rise 8-12 hours after the start of the fast. And also, Energy restriction for 10 to 14 hours or more results in depletion of liver glycogen stores and hydrolysis of triglycerides to release free fatty acids (FFA) in adipocytes.
AI correctly guided by a health professional can have positive effects on the body. Which are? We will tell you.
Effects Of Ai On Human Health
Scientific studies indicate that fasting is evolutionarily embedded in our physiology, triggering several essential cellular functions . Thus, changing the state of eating to fasting can help burn calories and lose weight, but also have a high resistance to stress, greater longevity, and a lower incidence of diseases, such as cancer and obesity.
This owed to the fact that adaptive cellular responses created during the fasting period. And makes cells participate in specific tissue processes of growth and plasticity during the feeding period, with important metabolic effects. however, Resistance to stress and suppression of inflammation reflected in extension of the useful life, delay of the aging, and resistance to the disease.
Some of the clinical applications of intermittent fasting are:
- Effects on health and aging
- Physical and cognitive effects
- Effects against obesity and diabetes mellitus
- Effects against cardiovascular diseases
- Cancer prevention
- Effects against asthma, multiple sclerosis and arthritis
- Effects against surgical and ischemic injury
- Fast
Is intermittent fasting right for everyone?
It is not suitable for everybody; in fact, it is very important for the health professional to be able to assess whether the patient can put this model into practice within their diet, taking into account all the patient’s medical history and adaptations. Likewise, this model should be put into practice only with the correct guidance of a nutrition professional.
It not recommended in:
- People experiencing an eating disorder (ED)
- Chronic gastritis
- Diabetes type 1
- Kidney or liver failure
- Pregnancy and breastfeeding
Does Intermittent Fasting Have Disadvantages?
Most of the scientific studies that affirm its effectiveness were carry out in animals.
- Human studies have small samples and for short periods of time.
- It is not sustainable over time.
- It can generate frustration or alter mental well-being
- and also, It can cause digestion problems
- May alter hunger and satiety signals
- May cause fatigue or weakness
In conclusion, intermittent fasting can be beneficial to the health of certain people but it is not applicable for everyone. The nutrition professional must evaluate whether the patient applies as a candidate and must carry out the schemes with the type of fasting that best suits the patient. Therefore, It is of great relevance that the diet is varied and balanced.
