Amazingly and unexpectedly, the English singer Adele appeared after she lost a lot of weight, and her image topped the newspapers and social media, after she was a symbol of the necessity of women accepting their bodies, and that the extra weight is not an obstacle to success.
Success is not enough
The songs of Adele, 32, who won more than 32 international awards, including the Oscars, Golden Globe and Grammy, were on the top lists watching and listening on YouTube and Spotify, but this success was not enough to stop her criticism because of her extra weight.
Adele commented about her criticism and harsh comments about her weight in a previous interview on the "60 Minutes" program in 2015, saying, "I have always received questions about my body, my weight, my size, and things like that. It is disturbing that men do not receive this kind of question very much." .
"It seemed to me that people were amazed that my size was huge and yet I had success."
Adele has appeared over the years in various forms that reveal her attempts to lose weight, but her last appearance was shocking after she lost 45 kilos, according to the newspaper "People."
What is Adele's secret?
According to Insider's health, the secret behind Adele's losing a lot of weight is to follow the "Certfood" diet, which she first began trying in 2017. She also announced that she had refrained from tea, smoking and alcohol.
Sertofood Diet is a system that includes eating foods that stimulate a type of protein called "Sertuin", in addition to reducing calories for weight loss.
The first stage consists of seven days, starting with only 1,000 calories in the first three days, then 1500 calories in the remaining four days. According to the New York Post, this system can lose more than three kilograms in the first seven days.
Then the second stage comes and consists of two weeks, and it is called the "maintenance" stage in which weight loss continues, and includes eating three meals with certain ingredients and one green juice per day, and these two stages are repeated according to the need to lose weight.
This system is not considered common, as it spread in 2016 in a book titled "Certfood Diet" by pharmacist Aidan Jujens and nutritionist Glenn Matin.

Sertfood relies on a number of foods that are considered healthy, such as some fruits such as strawberries, blueberries, apples, and blueberries, some vegetables such as onions, celery, parsley, arugula, kale, citrus fruits, and grains such as buckwheat, and other things such as nuts, dark chocolate, green tea and coffee.
Besides the high protein content of these foods, they also contain many nutrients such as vitamins and micronutrients, anti-oxidants and anti-inflammatory that protect against chronic and aging diseases.
According to a study published in the American National Library of Medicine, these foods that activate the sertuine protein affect the metabolism of weight loss, and also help to improve mental and neurological health and extend life.
And foods rich in protein Sertoin are common in areas where the population lives long, which are known as "blue areas" such as Greece, Japan, Costa Rica, Italy and California.
Despite these benefits, the Sertofood diet depends on eating a limited number of foods in a certain way and quantity, excluding many nutrients such as animal protein sources such as chicken, and some vegetables such as beans, and avoiding healthy fats and whole grains, which has a significant impact in the long run. There is no evidence that this list is reliable only.
What is dependent on this system of eating less than 1500 calories only during the day, is less than the rate required to be dealt with to obtain sufficient energy per day.
According to Harvard Medical School publications, losing weight at a rate of half to one kilogram per week - a rate experts consider safe - allows you to reduce the calories consumed during the day at a rate of five thousand to one thousand calories, so if you need 2325 calories to maintain your current weight, You can reduce it to between 1325 and 1825 for weight loss, as well as exercise for at least 30 minutes.
"Any diet that relies strictly on reducing calories may be very difficult to follow in the long run," nutrition expert Rachel Hartley told the Insider newspaper.
"A thousand calories is less than the recommended daily amount for a two-year-old, so adults cannot eat that, and we will not expect them to be energy-rich, as they will not have enough energy to carry out their daily activities."
Therefore, what depends on those who follow the Serfood system by eating less than 1500 calories only may pose a threat to their health, may cause malnutrition, and cannot be relied upon continuously.
Adele's photos may look amazing and encouraging to follow her diet, but this diet may not be suitable for everyone, and it is advised to go to dietitians before following it.
