Many people go through the already finished diet and drink too much.
To offset, some abstain from alcohol during the first month of the year. It is a trend called "Dry January", and experts say it's growing in popularity.
Tim Stockwell, director of the Canadian Institute for Substance Research in Victoria, says that one month of drinking, even for social drinkers, can have real benefits.
"It's a decision we can all make, and I think the advantage of something like this is a challenge to discover what [alcohol] not for you, "Stockwell told On the shore hosted by Gloria Makarenko.
"Having the experience of trying to go without a month, you also feel how central is in our social and cultural life."
Stockwell pointed to recent research from the University of Sussex, which showed that the majority of people who participated in dry public challenges experienced long-term benefits.
For example, 88 percent of participants found that they are saving money; 71 percent sleep better; 67 percent had more energy and 58 percent lost weight.
"The simple act of taking alcohol helps people drink less in the long run: by August, people report another dry day a week," says researcher Richard de Visser in a statement.
"Interestingly, these changes in alcohol consumption have also been observed among participants who have not been able to stay out of alcohol for the entire month – even though they are slightly smaller. This shows that there are real benefits just to try to finish dry January."
Stockwell encourages people to try one month without alcohol.
"It's not just January: there's" Silver October ", here is" Dry July, "he said, adding that the trend seems to be catching on young people." We are a little confused why this is the case. "
