Diets fail over time
This article from News-medical.net gives a solid dose of reality concerning the efficacy of various diets. Bottom line, they are not large differences in the results from various diets and the benefits of all diets tend to dissipate over time.
Those who are searching for the perfect diet can expect to be disappointed as the researchers say all diets have just about the same result, and none of them are brilliant.
Dr. Michael Dansinger of the Tufts-NewEnglandMedicalCenter in Boston and colleagues analyzed 46 trials that included 6,386 people who were participating in dietary counseling-based weight loss programs and 5,467 people not involved in formal weight loss programs.
They found that programs with more frequent meetings and greater calorie restrictions tended to produce greater weight losses over time but while around half the weight loss remained at three years, almost none of the weight loss remained at five years.
The article also aptly summarizes the reason for dieting: Overweight and obesity are known risk factors for diabetes, coronary heart disease, high blood pressure, stroke, hypertension, degenerative joint disease of the knees and hips, and some forms of cancer, among other conditions.
The sad reality is that while diets do work, very few people are prepared to stay on them indefinitely and therefore, over time, the weight loss from diets are reversed. Diets can help one lose, but one must essentially understand that they must permanently alter their eating and exercise patterns to lose weight and keep it off. A sound knowledge of the calorie content of the foods you imbibe daily is a good place to start on your quest for a permanent change in lifestyle that can lead to the significant health benefits of a normal BMI.
