Research shows that most forms of intermittent fasting, including alternate-day fasting, fasting , and time-restricted eating can help improve cardiometabolic health 5.

In fact, a review that analyzed seven randomized controlled trials of alternate-day fasting with a total of participants concluded that it can benefit cardiometabolic health 6 by reducing participants' weight, body mass index BMI , cholesterol levels, triglyceride levels, and blood pressure.

Improved cardiometabolic health can help reduce the risk of developing heart disease, heart attack, and stroke 7. A review published in Nutrients notes that alternate-day fasting enables autophagy 8 , which is an internal housekeeping process that your body uses to repair or dispose of damaged cells and molecules.

For instance, the body might patch up or recycle damaged or miscopied proteins or DNA molecules, Steve Hendricks , a health journalist, previously told mindbodygreen. By increasing autophagy 9 , fasting essentially helps clean and reboot your cells, Chris Palmer, M. Your body's ability to repair itself declines with age 10 , but by promoting autophagy, alternate-day fasting may help prevent age-related health conditions.

Inflammation is your body's natural defense against injury or illness. However, inflammation can be harmful if it persists for too long. Chronic inflammation has the opposite effect on your system, and it increases your risk of developing chronic diseases. Inflammation can be measured by checking your levels of C-reactive protein CRP , via a hs-CRP blood test.

A randomized control trial with 80 participants found that alternate-day fasting helped reduce hs-CRP levels 11 in patients with metabolic syndrome. A review notes that the various types of intermittent fasting may be able to prevent or improve inflammatory and autoimmune conditions 12 such as diabetes, arthritis, psoriasis, spondylitis, multiple sclerosis, and asthma.

Alternate-day fasting can help improve molecular and physiological markers of aging, according to Saeed. For instance, a randomized controlled trial with healthy adult participants found that within four weeks of practicing alternate-day fasting, participants had higher levels of beta-hydroxybutyrate 13 in their blood.

This compound delays aging and promotes longevity, Saeed explains. The study also found that alternate-day fasting helped reduce methionine, an amino acid associated with aging 14 , and sICAM-1, an age-associated inflammatory marker.

It's worth noting that improved cardiometabolic markers, increased autophagy, and reduced inflammation also contribute to improved longevity. Alternate-day fasting can be an effective way to achieve weight loss , says Saeed. A review notes that in addition to reducing body weight, it can also be an effective way to reduce 11 body mass index BMI , fat mass, waist circumference WC , and waist-hip ratio WHR.

However, Saeed explains that weight loss depends on various factors. For instance, she says making sure you exercise while you're following this fasting regimen can help you preserve muscle mass while losing fat.

On the other hand, she cautions that eating excess calories on feeding days will derail weight loss goals Therefore, it's important to eat a balanced and nutritious diet on feeding days and maintain an active lifestyle while you follow this fasting regimen.

If you've tried alternate-day fasting for weight loss and found it too restrictive, it may be helpful to try other forms of fasting that are easier to sustain, such as fasting. The healthiest weight management strategy is the one you can stick with in the long term.

While alternate-day fasting can be helpful to some people, it may not be safe or appropriate for everyone. Gandhi recommends avoiding this fasting regimen if you are under 18 years old, breastfeeding, pregnant or planning on becoming pregnant , underweight, or have a history of eating disorders.

If you do plan on trying alternate-day fasting, Gandhi recommends working with a health care provider such as a doctor or dietitian who can determine whether it's safe for you and tailor it to your needs. It's important to practice fasting under medical supervision.

Otherwise, you can easily become fatigued or dehydrated, or experience vitamin, mineral, and electrolyte deficiencies, says Gandhi. Other side effects of fasting 17 include fatigue, hunger, low mood, irritability, difficulty concentrating, food-related thoughts, and fear of losing control and overeating on non-fasting days.

Fasting can also lead to orthorexia 18 , an obsession with healthy eating, and contribute to the development of other eating disorders, Gandhi adds. While the ideal length of time to follow this fasting protocol varies from person to person, it's not advisable to follow such a restrictive fasting plan long term, Gandhi cautions.

Furthermore, most people will find it difficult to comply with such a challenging fasting regimen on a long-term basis. Research studies often see a high dropout rate , putting the sustainability of the diet into question.

An analysis of an alternate-day fasting study conducted over 12 months found that people had difficulty sticking to their calorie goals 19 on both fasting and feeding days; they were eating more calories than they should on fasting days and fewer calories than they should on feeding days, so by the end, their diet more closely resembled that of a traditional calorie restriction diet.

If you want to try intermittent fasting but think that alternate-day fasting may be too challenging for you, these are some less restrictive types of fasting to explore:.

Alternate-day fasting causes your body to go into a state of ketosis, where it burns stored fat as energy. In addition to helping you lose weight, this metabolic state also offers other health benefits, such as reduced inflammation and better cardiometabolic health.

Some think that ADF increases your risk of binge eating , but studies have found that it may help reduce binge eating behavior and decrease depressive symptoms. It may also improve restrictive eating and body image perception among people with obesity.

However, more research on the effectiveness and safety of ADF in people with disordered eating tendencies is needed It could work, the very limited research shows.

One example: Twenty-three obese men and women followed the diet for 12 weeks in a small study published in the journal Nutrition and Healthy Aging.

Compared to a group that had eaten normally and not within a set timeframe, those on the diet took in fewer calories per day, lost a modest amount of weight about three percent of their body weight on average , and lowered their blood pressure. Interestingly, following this kind of eating plan may help with appetite control.

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.

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.
