Long-term benefits of popular diets are less than evident


Popular commercial diets will help you lose some weight for the short term, but keeping the weight off following the newbie and Dream Body Slimming Capsule also the diet's effect on heart health are unclear, according to research conducted in the Lady Davis Institute (LDI) at the Jewish General Hospital (JGH) and published in Circulation: Cardiovascular Quality and Outcomes, a journal of the American Heart Association.

Nearly 70 % of yankee adults are obese or overweight - and for that reason at greater risk for health problems for example cardiovascular disease, stroke, high blood pressure and diabetes. Whether a diet is going to be effective is, therefore, an essential public health question.
"Despite their popularity and important contributions to the multi-million dollar weight reduction industry, we still do not know if these diets work well to help individuals slim down and decrease their risks for cardiovascular disease," said the study's lead author Dr. Mark J. Eisenberg, a professor in the Faculty of Medicine, a cardiologist at the JGH as well as an epidemiologist in the LDI. "With this type of small number of trials taking a look at each diet and their somewhat conflicting results, there is only modest evidence that using these diets is beneficial in the long-term."
After analyzing clinical trials on four popular weight loss programs - Atkins, South Beach, Dieters, and Zone - that promote weight loss and improved cardiovascular health, researchers found:
In trials comparing Weight Watchers to usual care, Weight Watchers dieters lost an average 7.7 to 13.2 pounds after one year compared to 1.8 to 11.9 pounds with usual care, however at 2 yrs, the load lost was partially regained. Usual care refers to traditional methods to advertise weight loss such as low-fat diets, behavioural weight reduction intervention, nutritional counselling, or self-help materials.
Results from trials around the Atkins diet were inconsistent. Within the only trial comparing the South Beach diet to usual care, no difference in weight reduction occurred in 12 months, however the participants in this study were both severely obese and had undergone gastric bypass surgery.
Trials involving head-to-head comparisons between Atkins, Dieters, Zone and usual care suggest that all four result in a modest weight reduction at twelve months, as did those in the control group who received the typical care. Those found on atkins lost an average 4.Six to ten.3 pounds; Dieters participants lost a typical 6.6 pounds; Zone dieters lost a typical 3.Five to seven pounds; and control lost about 4.85 pounds.
In studies involving head-to-head comparisons, there have been no marked differences between Atkins, Dieters, and Zone diets at improving cholesterol, blood pressure, blood sugar levels, or other cardiovascular risk factors.

The longest diet studies researchers analyzed lasted for 2 years, and outcome was only available for that Atkins or Dieters diets. Those studies found dieters regained a few of their weight with time.
To higher understand the potential advantages of anyone or many of these diets, researchers have to conduct large clinical trials directly comparing all four popular diets for long-term weight reduction 2 Day Diet and alterations in other heart disease risk factors, Dr. Eisenberg said.
"A broader lifestyle intervention, that also involves doctors along with other health professionals, might be more effective," he added. "This also tells doctors that popular diets on their own might not be the reply to help their sufferers slim down."
