Alternate day fasting regimens have increased in popularity because some patients find it difficult to adhere to a conventional weight-loss diet.
A new article published by JAMA Internal Medicine reports on a randomized clinical trial that compared the effects of alternate-day fasting with daily calorie restriction on weight loss, weight maintenance and indicators of cardiovascular disease risk.
Krista A. Varady, Ph.D., of the University of Illinois at Chicago, and coauthors included 100 obese adults in the single-center trial, which was conducted between October 2011 and January 2015. Patients were assigned to 1 of 3 groups for one year: alternate-day fasting (25 percent of calorie needs on fast days; 125 percent of calorie needs on alternating "feast" days); daily calorie restriction (75 percent of calorie needs every day); or no intervention.
After one year, weight loss in the alternate-day fasting group (6.0 percent) was not significantly different from the daily calorie restriction group (5.3 percent), according to the results.
"The results of this randomized clinical trial demonstrated that alternate-day fasting did not produce superior adherence, weight loss, weight maintenance or improvements in risk indicators for cardiovascular disease compared with daily calorie restriction," the article concludes.
The authors note some study limitations, which included a short maintenance phase of six months.

Expect some "fasting sucks" type write-ups from the Daily Mail, etc., and a rebuttal post from Dr. Fung soon.
Biggest failure in this study from my own experience--the fasting group was supposed to eat 500 calories one day, and above maintenance by 25 percent the next, what happened is that they ate a bit over 500 one day, and then underate the next. Brad Pilon is a big fan with his eatstopeat of putting all of the calorie deficit on the fasting days, this way, if you don't eat one day a week but eat full calories the rest, 86 percent of the time you're sort of not dieting, it makes sense for there to be less of an adaptation the less time you spend in an actual deficit. With IF--I find I can sustain every other day eating quite well, as long as the eating days involve abundant food, but things can derail quickly if I eat low on the eating days--I can get by with the odd low day, especially if it's very ketogenic,, but I can't sustain a full week of every other day eating unless I'm doing what would otherwise be "overeating" without the fasting days.
