Intermittent Fasting

Drª Ana Rita Horta, Nutritionist

 

It is known that fasting results in ketogenesis (a process that occurs in the liver, in which after the adaptation process, most tissues start using fatty acids - fat - as fuel, saving glucose - sugar - and initiating ketogenesis).
In addition to this energy function, the ketone bodies originated in this process are responsible for avoiding the feeling of hunger, a very important factor for the performance of a weight loss process.
This metabolic adaptation of the body to obtain energy seems to bring several advantages, and although more studies are needed to definitively conclude the effective benefits of this method, the literature points to the main effects of Fasting:

 

Changes in body composition (weight loss, loss of body fat);
Increased insulin sensitivity and consequent improvement in blood glucose control;
Cardiovascular effects (decrease in visceral fat, improvement in lipid profile, namely lower cholesterol and blood triglycerides);
Decreased intensity and frequency of seizures in patients with epilepsy;
Impact on aging and cognition (decrease in the rate of biological aging);
Assist in the modulation of the intestinal microbiota;
Reduced oxidative stress and reduced inflammatory profile.

Intermittent fasting is a dietary pattern in which periods of fasting and feeding alternate in periods of abstinence or longer or shorter periods of food intake.

While it is undoubtedly a growing trend, it is vital to remember that it is by no means the true miracle, let alone the perfect solution for everyone. This practice is not recommended for children and adolescents, high-performance athletes, diabetics, pregnant women, and individuals with chronic illnesses.
