Fasting window and meal timing -
This IF method results in just as much weight and fat loss as those who followed traditional dieting methods, according to a recent study published in PLOS ONE. As the name implies, this diet involves fasting every other day. There are several different versions of this plan, with some of them allowing about calories on the fasting days, and some encouraging that you eat even fewer or close to zero calories on fasting days.
Much of the weight loss-focused research hasn't been conclusive. And this style of intermittent fasting was deemed not superior to a calorie-restricted diet in terms of weight loss or maintenance in a JAMA study. IF schedules that require 24 hours of fasting are harder to stick to and people tend to experience more side effects, including mood swings and hunger, according to White.
So, only try this if you have done IF before and are willing to track your calorie intake and cut down the intensity of your workouts on fasting days to avoid injury. This method of intermittent fasting involves a full fast for 24 hours once or twice a week.
For example, you may eat dinner at 6 p. and then fast until 6 p. the next day, and you would do this one or two times per week—but not in a row. Keep in mind that not eating for an entire day can be dangerous under certain circumstances and should not be taken lightly. While the weight-loss potential might be appealing, skipping full days of eating is not sustainable long-term.
This one is similar to the method, but involves fasting for a hour window and eating for It's a little easier to stick to than because you have a longer eating window.
But that doesn't mean it's not effective. They also showed a more significant improvement in blood glucose levels after eight weeks. Given that the fasting period is short and pretty much follows the way people already eat, it may be hard for some people to achieve a calorie deficit with this diet.
Still, it could be a good way to ease into IF if you're new to it and want to see how you do when you have a specific timeframe for eating. It's also a great option if you like to get your workouts in between 8 a. and 10 a.
This diet is way different from the rest, with the majority of eating happening at night. The Warrior Diet was coined by fitness author Ori Hofmekler. It involves eating only small portions of raw fruits and vegetables during the day, then feasting on one huge meal at night within a 4-hour eating window.
There's no specific research on the Warrior Diet. While the fasting periods still allow for some food, the period when you can have heavier foods is very short, and the diet also involves focusing on paleo foods, so it's stricter than other forms of IF.
And like the eat-stop-eat diet, this option is not sustainable long-term. You're just going to hurt yourself if you go this route. Although there is limited research, the initial findings are promising. Here are the potential benefits of IF based on recent studies.
In short, the one that's easiest for you to follow. If not, then you'll likely not see the results you're looking for, as the sustainability piece will not be there.
It's worth pointing out, though, that the diet seems to be the most doable for a lot of people who are into IF. The method also scores points for preventing overeating at night, which can often be a big obstacle for weight loss.
Now, any weight loss that you experience from IF is most likely due to the basic fact that you're consuming less calories, not necessarily the timing of your eating, says Lemein.
And you can totally eat less, and lose weight, without taking on fasting. Case in point: Intermittent fasting had similar weight loss results to a traditional calorie-restricted diet, a meta-analysis published in the JBI Database of Systematic Reviews and Implementation Reports found.
So, unless fasting makes dieting easier for you, there's really no reason to choose IF over other diets. Ashley Martens is a wellness writer based in Chicago.
