Looking for diets that work doesn't only apply in the summer time as people get ready for swimsuit season.

People are constantly taking interest in popular diets that are advertised to work such as Weight Watchers or Atkins, but researchers have found that these diet fads aren't as effective as living healthily for weight loss and are unlikely to provide long term health benefits, according to The Telegraph.

Although people were reportedly found to have initially lost weight in the short term, they regained the pounds within two years, according to the results of the study in which researchers at McGill University compared diets against traditional methods such as regular exercise and healthy eating.

"Despite their popularity and important contributions to the multi-million dollar weight loss industry, we still do not know if these diets are effective to help people lose weight and decrease their risk factors for heart disease," stated senior author Dr. Mark Eisenberg, Professor of Medicine at Jewish General Hospital/McGill University in Canada.

He continued, "With such a small number of trials looking at each diet and their somewhat conflicting results, there is only modest evidence that using these diets is beneficial in the long-term."

Despite the results of the recent research, people reportedly spend more than $66 billion a year on these branded diets in order to lose weight, according to the media outlet Tech Times.

"What is incredible to me is that dieting is a multibillion-dollar industry, and if we look at the amount of data out there, it's minuscule in comparison to the market. There are very few well-done studies, and most of them look at the short term. And weight loss is obviously a long term issue," stated Eisenberg.
