Jason, a professor of medicine at the Mayo Clinic, said that regardless of the extreme calorie restriction method, the diet is more moderate, and in the long run, the dieter will eventually lose the same weight. But the research director, Johannson of Caroline College in Sweden, said that eating only very low-calorie foods and losing weight quickly can affect the salt and cholesterol levels in the bile and empty the gallbladder, both of which can cause gallstones. . In the United States, there are as many as 20 million patients with gallstones.
To understand the effects of dieting on gallstones, Johansson and his companions surveyed 6,640 dieters at the Intrim Weight Loss Center in Sweden, half of which used a crash diet and the other half with a low-calorie diet.
People who use the quick diet diet eat only 500 calories a day for 6 to 10 weeks, then gradually add normal food, and maintain weight through exercise and a healthy diet for the next nine months.
People who are moderately lose weight eat two meals a day, consume 1200 to 1500 calories for a period of 3 months, and then have a 9-month weight retention period.
According to a report published in the International Journal of Obesity, three months after the start of weight-loss therapy, the fast-acting dieter lost about 30 pounds (about 13.6 kilograms) and the milder was 17 pounds. After one year, the quick-wackers lost an average of 24.5. The pound, the other group is about 18 pounds.
Among the quick-acting dieters, 48 were hospitalized for gallstones and 16 were in the other group. This result demonstrates that using extreme calorie restriction to lose weight is more likely to suffer from gallstones.
