6 Popular Ways to Do Intermittent Fasting
It's claimed to cause weight loss, improve metabolic health, and perhaps even extend lifespan.
Not surprisingly given the popularity, several different types or methods of intermittent fasting have been created.
Every method can be effective, but figuring out which one works best depends on the individual.
Here are 6 popular ways to do intermittent fasting.
1. The 16/8 Method: Fast for 16 Hours Each Day
The 16/8 Method involves fasting every day for 14 to16 hours and restricting your daily "eating window" to 8-10 hours.
Within the eating window, you can fit in 2, 3, or more meals.
This method is also known as the Leangains protocol and was popularized by fitness expert Martin Berkhan.
Doing this method of fasting can actually be as simple as not eating anything after dinner and skipping breakfast.
For example, if you finish your last meal at 8 p.m. and don't eat until noon the next day, you're technically fasting for 16 hours.
It's generally recommended that women only fast 14-15 hours, because they seem to do better with slightly shorter fasts.
For people who get hungry in the morning and like to eat breakfast, this method may be hard to get used to at first. However, many breakfast skippers actually instinctively eat this way.
It's very important to primarily eat healthy foods during your eating window. This method won't work if you eat lots of junk food or an excessive number of calories.
The 16/8 method involves daily fasts of 16 hours for men and 14-15 hours for women. Each day you'll restrict your eating to an 8- to 10-hour "eating window" where you can fit in 2, 3, or more meals.
2. The 5:2 Diet: Fast for 2 Days Per Week
This diet is also called The Fast Diet and was popularized by British journalist Michael Mosley.
On the fasting days, it's recommended that women eat 500 calories and men eat 600 calories.
For example, you might eat normally every day of the week except Mondays and Thursdays. For those two days, you eat two small meals (250 calories per meal for women and 300 calories for men).
As critics correctly point out, there are no studies testing the 5:2 diet itself, but there are plenty of studies on the benefits of intermittent fasting.
The 5:2 diet, or the Fast diet, involves eating 500-600 calories for two days out of the week and eating normally the other 5 days.
3. Eat-Stop-Eat: Do a 24-Hour Fast, Once or Twice a Week
Eat-Stop-Eat involves a 24-hour fast, either once or twice per week.
This method was popularized by fitness expert Brad Pilon and has been quite popular for a few years.
By fasting from dinner one day to dinner the next day, this amounts to a full 24-hour fast.
For example, if you finish dinner at 7 p.m. Monday and don't eat until dinner at 7 p.m. the next day, you've just done a full 24-hour fast.
You can also fast from breakfast to breakfast or lunch to lunch. The end result is the same.
Water, coffee, and other noncaloric beverages are allowed during the fast, but no solid foods are permitted.
If you're doing this to lose weight, it's very important that you eat normally during the eating periods. As in, eat the same amount of food as if you hadn't been fasting at all.
The potential downside of this method is that a full 24-hour fast may be fairly difficult for many people.
However, you don't need to go all-in right away. Starting with 14-16 hours and then moving upward from there is fine.
I've personally done this a few times. I found the first part of the fast very easy, but in the last few hours, I became ravenously hungry.
I needed to apply some serious self-discipline to finish the full 24 hours, and I often found myself giving up and eating dinner a bit earlier.
Eat-Stop-Eat is an intermittent fasting program with one or two 24-hour fasts per week.
4. Alternate-Day Fasting: Fast Every Other Day
Alternate-day fasting means fasting every other day.
There are several different versions of this method. Some of them allow about 500 calories during the fasting days.
Many of the lab studies showing health benefits of intermittent fasting used some version of this method.
A full fast every other day can seem rather extreme, so it's not recommended for beginners.
With this method, you will be going to bed very hungry several times per week, which is not very pleasant and probably unsustainable in the long term.
Alternate-day fasting means fasting every other day, either by not eating anything or only eating a few hundred calories.
5. The Warrior Diet: Fast During the Day, Eat a Huge Meal at Night
The Warrior Diet was popularized by fitness expert Ori Hofmekler.
Basically, you "fast" all day and "feast" at night within a 4-hour eating window.
The Warrior Diet was one of the first popular "diets" to include a form of intermittent fasting.
This diet also emphasizes food choices that are quite similar to a paleo diet — whole, unprocessed foods that resemble what they looked like in nature.
The Warrior Diet is about eating only small amounts of vegetables and fruits during the day and eating one huge meal at night.
6. Spontaneous Meal Skipping: Skip Meals When Convenient
You don't actually need to follow a structured intermittent fasting plan to reap some of the benefits.
Another option is to simply skip meals from time to time, such as when you don't feel hungry or are too busy to cook and eat.
It's a myth that people need to eat every few hours or they'll hit "starvation mode" or lose muscle.
The human body is well equipped to handle long periods of famine, let alone missing one or two meals from time to time.
So, if you're really not hungry one day, skip breakfast and just eat a healthy lunch and dinner. Or, if you're traveling somewhere and can't find anything you want to eat, do a short fast.
Skipping one or two meals when you feel inclined to do so is basically a spontaneous intermittent fast.
Just make sure to eat healthy foods during the other meals.
Another more "natural" way to do intermittent fasting is to simply skip one or two meals when you don't feel hungry or don't have time to eat.
The Bottom Line
There are a lot of people getting great results with some of these methods.
Intermittent fasting is not for everyone. It's not something that anyone needs to do. It's just another tool in the toolbox that can be useful for some people.
Some also believe that it may not be as beneficial for women as men. It may also not be a recommended choice for people who have or are prone to eating disorders.
If you decide to try intermittent fasting, keep in mind that you need to eat healthy as well.
It's not possible to binge on junk foods during the eating periods and expect to lose weight and improve health.
Calories still count, and food quality is still absolutely crucial.

The SARS-CoV-2 virus is novel, but pandemic threats to indigenous peoples are anything but new. Diseases like measles, smallpox and the Spanish flu have decimated Native American communities ever since the arrival of the first European colonizers.

History Reverberates on Native Lands<p>Native communities in North America have been disrupted and displaced for centuries. Many face long-standing food and water <a href="http://www.nativepartnership.org/site/DocServer/2017-PWNA-NPRA-Food-Insecurity-Project-Grow.pdf?docID=7106" target="_blank">inequities</a> that are further complicated by this pandemic.</p><p>On the Navajo reservation, which covers more than 27,000 square miles in Arizona, Utah and New Mexico, 76% of households already <a href="https://www.researchgate.net/publication/235390130_High_levels_of_household_food_insecurity_on_the_Navajo_Nation" target="_blank">have trouble affording enough healthy food</a>, and the nearest grocery store is often hours away. COVID-related restrictions have further curtailed access to food supplies.</p><p>Clean water for basic sanitary measures like hand-washing is also scarce. Native Americans are <a href="http://uswateralliance.org/sites/uswateralliance.org/files/Closing%20the%20Water%20Access%20Gap%20in%20the%20United%20States_DIGITAL.pdf" target="_blank">19 times more likely</a> to lack indoor plumbing than whites in the U.S. Nearly one-third of Navajo households <a href="https://www.nbcnews.com/news/us-news/coronavirus-hits-indian-country-hard-exposing-infrastructure-disparities-n1186976" target="_blank">lack access to running water</a>.</p><p>Many <a href="https://www.cdc.gov/mmwr/volumes/69/wr/mm6915e3.htm" target="_blank">health issues</a> that can increase COVID-19 mortality rates occur at high levels among Native Americans. These <a href="http://www.ncai.org/news/articles/2020/03/18/the-national-congress-of-american-indians-calls-for-more-attention-to-covid-19-impacts-to-indian-country" target="_blank">underlying</a> and <a href="https://doi.org/10.1016/S0140-6736(20)30893-X" target="_blank">preexisting</a> conditions – things like hypertension, diabetes, obesity and cardiovascular disease – are <a href="https://www.cdc.gov/mmwr/volumes/69/wr/mm6913e2.htm" target="_blank">linked to diet</a> and stem from <a href="https://www.oupress.com/books/15107980/indigenous-food-sovereignty-in-the-united-sta" target="_blank">disruption and replacement</a> of Indigenous food systems.</p>
High Exposure Rates<p>These factors have clear health impacts. On the Navajo reservation, for instance, through May 27, 2020, <a href="https://www.navajo-nsn.gov/News%20Releases/OPVP/2020/May/FOR%20IMMEDIATE%20RELEASE%20-%201620%20recoveries_102%20new%20cases%20of%20COVID-19_and%20one%20more%20death%20reported.pdf" target="_blank">4,944 people</a> out of a population of 173,000 had tested positive for COVID-19, and 159 had died.</p><p>This infection rate per capita exceeds those in hot spots such as <a href="https://www.forbes.com/sites/alexandrasternlicht/2020/05/19/navajo-nation-has-most-coronavirus-infections-per-capita-in-us-beating-new-york-new-jersey/#11a4fac08b10" target="_blank">New York and New Jersey</a>. Importantly, however, it may also reflect a much <a href="https://www.sltrib.com/news/2020/04/19/navajo-nation-has-higher/" target="_blank">more proactive approach to testing</a> on reservations than in many other jurisdictions.</p><p>The fact that elderly people are especially vulnerable to COVID-19 could worsen the pandemic's effects in Indian Country. Elders are the <a href="https://ais.washington.edu/research/publications/spirits-our-whaling-ancestors" target="_blank">keepers of traditional knowledge, tribal languages and culture</a> – legacies whose loss already threatens the persistence of indigenous communities.</p><p>Elders also play key roles in preserving traditional plant and medicine knowledge. In the absence of COVID-19 interventions from Western medicine, many elders have been called on to perform healing practices, which increases their exposure risk.</p>
Little Help From Federal and State Governments<p>Many tribal members rely on the federal government's <a href="https://www.ihs.gov/" target="_blank">Indian Health Service</a> for health care. But <a href="https://theconversation.com/tribal-leaders-face-great-need-and-dont-have-enough-resources-to-respond-to-the-coronavirus-pandemic-134372" target="_blank">lack of capacity</a> at the agency has hampered its response.

Environmental Injustices on Native Land<p>Energy development and resource extraction have had <a href="https://www.haymarketbooks.org/books/898-all-our-relations" target="_blank">disproportionate impacts</a> on tribes for many years. Today, many Native American leaders worry that ongoing energy production – <a href="https://www.ncsl.org/research/labor-and-employment/covid-19-essential-workers-in-the-states.aspx" target="_blank">an "essential" activity under federal guidelines</a> will bring outsiders into close contact with reservation communities, worsening COVID risks.</p><p>The owners of the Keystone XL oil pipeline have announced that they intend to continue construction, which will bring an influx of workers along the proposed route through Montana, South Dakota and Nebraska. The Rosebud Sioux Tribe in South Dakota and Fort Belknap Indian community in Montana have filed for a <a href="https://www.narf.org/keystone-xl/" target="_blank">temporary restraining order</a>, and a key permit for the pipeline was <a href="https://www.democracynow.org/2020/4/16/headlines/us_judge_revokes_crucial_permit_for_keystone_xl_pipeline" target="_blank">revoked in April 2020</a>, but work continues at the U.S.-Canada border.</p><p>Construction is accelerating on the <a href="https://www.azcentral.com/story/news/politics/border-issues/2020/03/17/border-patrol-waives-laws-border-wall-construction-southern-arizona/5063618002/" target="_blank">southern border wall</a>, which bisects the <a href="http://www.tonation-nsn.gov/" target="_blank">Tohono O'odham reservation</a> in Arizona and Mexico. The Trump administration has <a href="https://www.thenation.com/article/politics/border-coronavirus-military-immigration/" target="_blank">increased patrols at the border</a>, despite the tribe's concern that the patrols' presence is <a href="https://www.usatoday.com/story/news/nation/2020/04/06/coronavirus-cbp-160-cases-covid-19-officers-agents/2958736001/" target="_blank">spreading coronavirus</a> on the reservation.</p><p>And in Bristol Bay, Alaska, a salmon fishing season that brings in thousands of temporary workers is <a href="https://indiancountrytoday.com/news/it-s-hard-when-you-love-something-xlS49l2N20KZjqumwfzZfQ" target="_blank">set to open in June</a> because the federal government has also deemed commercial fishing "<a href="https://www.cisa.gov/sites/default/files/publications/CISA-Guidance-on-Essential-Critical-Infrastructure-Workers-1-20-508c.pdf" target="_blank">essential critical infrastructure</a>." Many local Native villages depend on the fishery for income, but have nonetheless pleaded with state regulators to <a href="https://indiancountrytoday.com/news/urgent-calls-to-close-the-massive-bristol-bay-fishery-8lYsGkUeDUyCBW7FMwpSfA?fbclid=IwAR1710u4rQnriq_MgH2ueQxOFtfGiGiH8I2ZdJRCZS9f28Zl-JNkPLpnzZo" target="_blank">cancel the season</a>.

Bold Action in Native Communities<p>Native communities are taking decisive action to reduce the spread of COVID-19.

The ocean is our lifeline - we rely on it for the food we eat, the air we breathe, as well as for millions for jobs worldwide.
As we continue to grapple with the issues of overfishing, plastic pollution, and climate change, there exists an opportunity to address these existential threats with new innovations, many of which unidentified or insufficiently supported.
