One study shows that dramatic weight loss due to a low calorie diet can be more effective than other types of weight control.
Researchers at Oxford University found that people who ate more than 810 calories a day through soups, shakes and bars lost more than three times more calories than other people a year later .
Dieters lost on average the first 9 lb (10.7 kg), a little more than a stone than other people who followed a diet recommended by their general practitioner. They also showed a greater reduction in their risk of developing heart disease, stroke and diabetes.
The results seem to contradict previous suggestions that people who lose weight quickly have a tendency to stack them.

The researchers found that those who ate no more than 810 calories a day through soups, shakes and bars lost more than three times more than other people on the diet a year later.
The study comes after NHS England unveiled radical plans to use "soup and shake" diets to treat diabetes, as reported in the Mail earlier this month.
The last trial involved 278 adults in Oxfordshire with a BMI greater than 30, which makes them clinically obese. Participants were asked to complete a 24-week low-energy total diet replacement program or participate in their firm's weight management program, which included nursing advice and support. Those who were on the diet replacement program were asked to reduce their intake to 810 calories per day by replacing all foods with soups, milkshakes and specially formulated bars, in addition to milk supplements, alcohol and other foods. water and fiber.
Food substitutes were offered for eight weeks, followed by a reintroduction of conventional food for another four weeks. From 12 to 24 weeks, they were encouraged to continue using one product a day to replace a regular meal.
They were also invited to attend regular meetings with a trained counselor to develop techniques to help them follow the diet and, subsequently, maintain their weight loss.
Nearly half (45%) of participants in the low-energy program achieved weight loss of 10% or more. Only 15% of participants in the general practice program achieved similar results.
The research was conducted at the University of Oxford (photo). Dr. Nerys Astbury, a senior researcher on diet and obesity at the university, said the program could be extended to the entire NHS.
Paul Aveyard, general practitioner and professor of behavioral medicine at Oxford University, said: "This study shows that referral to a full replacement program is an effective intervention that general practitioners can confidently recommend. . and reduces the risk of heart disease and diabetes. & # 39;
The study found no evidence that the diet replacement program increased the risk of adverse effects that interfere with daily life. Total diet replacement programs are suitable for most obese people and want to lose weight.
However, they may not be suitable for those who suffer from certain medical conditions or who are taking particular medications.
Dr. Nerys Astbury, a senior research scientist in diet and obesity at Oxford University, added, "This model of care offers a potential for rapid deployment on a large scale in the NHS and could help reduce the risk of stroke. pressure on doctors dealing with obesity. disease & # 39.
Dr. Barbara McGowan, Head of Medical Obesity Services at Guy's and St Thomas Hospital, said the program "could be developed across the NHS if it turns out to be cost effective as a treatment for obesity ".
