A relatively new method to accelerate weight loss without having so many dietary restrictions, but its long-term effects on health are not yet scientifically supported.
It is common to see new theories, therapies, or alternatives for losing weight. Every year, trends dictate a different method that may be more or less accepted. Today, intermittent fasting is one of the most popular; it consists of increasing the time intervals between meals and is not considered a diet in itself.
According to a report published on the Marca’s website CuídatePlus, the most common forms of intermittent fasting are daily, where people establish cycles of 12 to 16 hours in which no food or significant amounts of calories are ingested. In fact, eating early and waiting until breakfast for the next meal has always been considered a suitable practice that allows the digestive system to do its job.
There is also a weekly intermittent fasting, where you fast for 1 or 2 days a week or month. For example, a person might eat only during a 12-hour period, from 7am to 7pm. This reduces the usual caloric intake by 300 to 500 kilocalories per day. It has gained popularity because it does not limit the foods that can be consumed, but rather the times you can eat. However, according to Ana Zugasti, from the Nutrition Area of the Spanish Society of Endocrinology, it may only be a useful option for some people, since scientific evidence showing its long-term effects is still lacking.
Beyond its benefits, the expert warns that there may be risks or side effects of fasting such as headaches, dizziness, difficulty staying concentrated, or even the agitation of some diseases.
According to the specialist, people who have problems related to cholesterol, blood pressure, diabetes, or heart disease, pregnant or nursing women, children and adolescents, or people with eating disorders should always consult with a specialist before starting intermittent fasting.
