The Sirt food diet is to stimulate an enzyme that accelerates metabolism. However, foods that include this regimen may be insufficient for the body and cause irreversible health damage.
British singer Adele has gained more fame for her weight loss than for her music in recent months. Their diet has caused a stir around the world, but specialists warned that while it may be effective in the short term it is so restrictive that it is unsustainable in the long run because of the negative health effects it causes.
The already famous Sirt food diet was created by the British Aidan Goggins and Glen Matten and consists of consuming foods such as red fruits, chia seeds, olive oil, cocoa, tofu, nuts, cinnamon, matcha green tea, red wine, parsley and turmeric, among others. These foods are responsible for stimulating the enzyme responsible for accelerating metabolism, although, according to nutritionist Sara González Benito, this has been tested only in animals and has not been scientifically tested in humans.
This low-calorie diet consists of three phases:
- The first lasts three days and you can eat up to 1,000 calories that should be distributed in a solid meal and three vegetable shakes.
- The second lasts until you reach a “healthy weight” and allows you to consume 1,500 calories divided into two solid meals and three vegetable shakes.
- The third phase is the maintenance phase and allows you to consume 1,800 calories in three meals and with the three shakes.
Obviously, meals and smoothies should contain the aforementioned foods including lean proteins without saturated fats combined with intense exercise. At first glance, the diet appears to be harmless, but according to nutritionist Domingo Carrera, in the first phase we see muscle loss, weakness, hair loss, dry skin, dizziness and even brittle nails.
Not to mention that the body does not get essential nutrients such as iron, calcium and even B vitamins.
Specialists consider that this diet is so restrictive when it comes to eliminating several foods that it can be unsustainable for the same organism causing a rebound effect.
Nutritionist Gonzalez Benito added that when opting for a diet, the body does not understand what happens and responds by reducing the hormone of satiety regulation, increasing the desire for foods that are not allowed in the diet and this generates insomnia, lack of energy and even irritability.
“This superhuman effort will lead to weight recovery or greater weight gain,” concluded Gonzalez Benito.
