Studies on the matter have shown that intermittent fasting can help with weight loss by reducing overall calorie intake, which creates a calorie deficit and results in weight loss over time (<\/span><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC3680567\/\"><span style=\"font-weight: 400;\">1<\/span><\/a><span style=\"font-weight: 400;\">, <\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/29951594\/\"><span style=\"font-weight: 400;\">2<\/span><\/a><span style=\"font-weight: 400;\">, <\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/31339000\/\"><span style=\"font-weight: 400;\">3<\/span><\/a><span style=\"font-weight: 400;\">). As it doesn\u2019t require a complicated or restrictive diet or calorie counting, some people find it easier to maintain for long enough to experience significant weight loss.\u00a0\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It\u2019s important to note that most studies on intermittent fasting and weight loss typically employ longer eating windows (up to 12 hours), and there are limited studies specifically on the efficacy of a 4-hour eating window in promoting weight loss.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">With that being said, the available studies on the 20:4 intermittent fasting method do suggest that participants can experience some modest weight loss benefits when following this eating pattern:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In a study published in 2022, researchers compared the effects of a 6-hour eating window and a 4-hour eating window versus no meal timing restrictions on the body weight and cardiometabolic risk factors of participants.\u00a0<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">After 8 weeks, researchers found that the study participants who followed time-restricted feeding (4 hours and 6 hours) reduced their calorie intake by around 550 kcal a day, without counting calories, and also experienced mild weight loss (around 3% of body weight) (<\/span><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC9407646\/\"><span style=\"font-weight: 400;\">4<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<p><a href=\"https:\/\/quiz.betterme.world\/en\/first-page-generated?flow=1443&amp;utm_source=Blog&amp;utm_medium=Blog&amp;utm_campaign=20_Hour_Fasting_Diet\"><img decoding=\"async\" class=\"aligncenter size-large wp-image-79369\" src=\"https:\/\/cdn.betterme.world\/articles\/wp-content\/uploads\/2025\/07\/olesia-food-1024x640.png\" alt=\"\" width=\"770\" height=\"481\" srcset=\"https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/07\/olesia-food-1024x640.png 1024w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/07\/olesia-food-300x188.png 300w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/07\/olesia-food-768x480.png 768w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/07\/olesia-food-1720x1075.png 1720w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/07\/olesia-food.png 1920w\" sizes=\"(max-width: 770px) 100vw, 770px\" \/><\/a><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In a more recent study published in 2024, researchers compared the effects of 3 fasting methods, namely 16\/8 fasting, 20\/4 fasting, and alternate-day fasting, on the body weight and BMI of healthy individuals. The study was done for 8 weeks, and the results showed that (<\/span><a href=\"https:\/\/www.mdpi.com\/2072-6643\/16\/8\/1114?\"><span style=\"font-weight: 400;\">5<\/span><\/a><span style=\"font-weight: 400;\">)<\/span>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">The study participants in the ADF group lost a significant amount of weight and showed a significant drop in their BMI, which was not the case for the participants who followed the 16\/8 and 20\/4 intermittent fasting (IF) patterns.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">It was difficult for all participants to adhere to their fasting styles, which shows that while IF may be a popular weight loss plan, it is not fit for everyone.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Due to the lack of sufficient scientific research into the 20\/4 intermittent fasting plan, we can\u2019t tell you with certainty that this fasting pattern will help with your weight loss goals.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, just because the 20-hour fasting benefits are lacking doesn\u2019t mean you should give up on IF altogether if it\u2019s a good fit for you. As shown in the section above, there is scientific evidence that suggests that fasting methods with longer eating windows can be beneficial for weight loss. The key to success is to find a strategy that helps you reduce your calorie intake and that fits well with your lifestyle so you can stick with it long enough to see meaningful weight loss.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Together with weight loss, it is suggested that intermittent fasting provides other health benefits, such as:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reduced risk of type 2 diabetes (<\/span><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S193152441400200X\"><span style=\"font-weight: 400;\">6<\/span><\/a><span style=\"font-weight: 400;\">)<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reduced inflammation, which helps lower your risk of chronic illnesses (<\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/32947129\/\"><span style=\"font-weight: 400;\">7<\/span><\/a><span style=\"font-weight: 400;\">)<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Improved cardiometabolic risk factors (<\/span><a href=\"https:\/\/www.frontiersin.org\/journals\/nutrition\/articles\/10.3389\/fnut.2021.669325\/full\"><span style=\"font-weight: 400;\">8<\/span><\/a><span style=\"font-weight: 400;\">)<\/span><\/li>\n<\/ul>\n<p><em><strong>Read more:<\/strong> <a href=\"https:\/\/betterme.world\/articles\/does-fasting-help-lose-face-fat\/\">Does Fasting Help Lose Face Fat?<\/a><\/em><\/p>\n<h2 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"What_Happens_to_My_Body_After_20_Hours_of_Fasting\"><\/span><b>What Happens to My Body After 20 Hours of Fasting?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">After 20 hours of fasting, your body is usually in the third stage of the four stages\/cycles of fasting. This third stage, which is also known as the \u2018fasting stage\u2019, usually starts after 18 hours of going without food and can last up to 48 hours if you keep going without consuming any calories in that time frame.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In this stage, almost all the glucose (which comes from ingesting carbohydrates) has been used up by the body, and thus, you enter lipolysis. This then leads to (<\/span><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC5959807\/\"><span style=\"font-weight: 400;\">9<\/span><\/a><span style=\"font-weight: 400;\">)<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Increased muscle breakdown, which helps to produce glucose from protein.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Increased fat breakdown where the body turns stored body fats into ketones and uses this as an alternative energy source, since its primary source of energy, glucose, is nearly, if not completely, depleted.

Most health conditions and some medications can\u2019t go hand-in-hand with fasting, especially such a long fast. Therefore, to avoid any complications, consult a healthcare professional for guidance before you attempt this fasting plan.<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Start with Shorter Fasting Plans\u00a0<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">This is particularly important if you\u2019re a beginner to fasting. You need to train your body &#8211; and yourself &#8211; to go for prolonged periods without food, before you jump headfirst into the 20\/4 intermittent fasting plan.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Start with the 12:12 plan (12-hour fast, 12-hour eating window), then progress to the 14:10 plan (14-hour fasting window, 10-hour eating window), and then the 16:8 plan before finally attempting the 20-hour fasting diet.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This will help your body slowly get used to intermittent fasting and allow you to try different IF plans. You may even find that you\u2019re more comfortable with the 14:10 or 16:8 plan and have no desire to attempt the extreme 20:4 plan.<\/span><\/p>\n<p><a href=\"https:\/\/quiz.betterme.world\/en\/first-page-generated?flow=1443&amp;utm_source=Blog&amp;utm_medium=Blog&amp;utm_campaign=20_Hour_Fasting_Diet\"><img decoding=\"async\" class=\"aligncenter size-large wp-image-82837\" src=\"https:\/\/cdn.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/16_8-Intermittent-Fasting-7-Day-Meal-Plan-1024x640.png\" alt=\"\" width=\"770\" height=\"481\" srcset=\"https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/16_8-Intermittent-Fasting-7-Day-Meal-Plan-1024x640.png 1024w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/16_8-Intermittent-Fasting-7-Day-Meal-Plan-300x188.png 300w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/16_8-Intermittent-Fasting-7-Day-Meal-Plan-768x480.png 768w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/16_8-Intermittent-Fasting-7-Day-Meal-Plan-1720x1075.png 1720w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/16_8-Intermittent-Fasting-7-Day-Meal-Plan.png 1920w\" sizes=\"(max-width: 770px) 100vw, 770px\" \/><\/a><\/p>\n<ul>\n<li aria-level=\"1\"><b>Eat Something During the 20-Hour Fasting Window<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Not everyone agrees with this, but if it helps, you can consider consuming small amounts of raw vegetables and fruit to help you get through this long fasting window.<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Stay Hydrated<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">But only with water and other calorie-free drinks like unsweetened coffee and tea.

However, it\u2019s recommended to be strategic. Two of the main reasons why many people turn to IF for weight loss are:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It doesn\u2019t insist on calorie counting<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It doesn\u2019t limit food intake during the eating window<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">At a glance, this means that as long as you fast during the fasting window, you can eat whatever and however much of it you want during the eating window. However, if you dig a little deeper, you\u2019ll discover that if you want to lose weight and improve your health, you have to be mindful of what and how you eat during the eating window.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Instead of eating whatever you want after the 20-hour fast, be smart about your choices.<\/span><\/p>\n<p><a href=\"https:\/\/quiz.betterme.world\/en\/first-page-generated?flow=1443&amp;utm_source=Blog&amp;utm_medium=Blog&amp;utm_campaign=20_Hour_Fasting_Diet\"><img decoding=\"async\" class=\"aligncenter size-large wp-image-82864\" src=\"https:\/\/cdn.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/How-To-Get-Rid-Of-Water-Retention-Overnight_-Beat-Bloat-With-These-Tips-1024x640.png\" alt=\"\" width=\"770\" height=\"481\" srcset=\"https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/How-To-Get-Rid-Of-Water-Retention-Overnight_-Beat-Bloat-With-These-Tips-1024x640.png 1024w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/How-To-Get-Rid-Of-Water-Retention-Overnight_-Beat-Bloat-With-These-Tips-300x188.png 300w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/How-To-Get-Rid-Of-Water-Retention-Overnight_-Beat-Bloat-With-These-Tips-768x480.png 768w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/How-To-Get-Rid-Of-Water-Retention-Overnight_-Beat-Bloat-With-These-Tips-1720x1075.png 1720w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/How-To-Get-Rid-Of-Water-Retention-Overnight_-Beat-Bloat-With-These-Tips.png 1920w\" sizes=\"(max-width: 770px) 100vw, 770px\" \/><\/a><\/p>\n<ul>\n<li aria-level=\"1\"><b>Eat in a Caloric Deficit\u00a0<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">This helps you not overeat, which further helps with the weight loss goal. The reason intermittent fasting works for weight loss is that it helps you reduce your calorie intake without meticulous calorie counting. So stick with balanced meals and reasonable portions during your eating window.<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Choose Nutrient-Dense Foods\u00a0<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Especially those that are rich in protein and fiber.

But what if you could reduce the amount of time you spent hungry?\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><a href=\"https:\/\/betterme.world\/articles\/high-protein-high-fiber-meal-plan\/\">Fiber and protein-rich foods<\/a> have been shown to help with satiety. This helps you feel fuller for longer and also helps with appetite control, which, as previously mentioned, helps with eventual fat and weight loss.<\/span><\/p>\n<p><em><strong>Read more:<\/strong> <a href=\"https:\/\/betterme.world\/articles\/best-foods-to-eat-before-fasting\/\">Best Foods to Eat Before Fasting: Fuel Your Body Right<\/a><\/em><\/p>\n<h2 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Why_Am_I_Not_Losing_Weight_on_My_20-Hour_Fast\"><\/span><b>Why Am I Not Losing Weight on My 20-Hour Fast?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Three reasons for this could be:<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>You\u2019re Not Giving Yourself Enough Time to Notice Changes<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Contrary to what some people believe, weight loss changes don\u2019t happen immediately. In fact, it may take 6 to 8 weeks to start to see the initial changes in your weight loss. So instead of hopping on the bathroom scale or scrutinizing your body in the mirror, hoping to see changes, wait a while and be consistent with the fast.<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>You\u2019re Over- or Undereating<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">As mentioned above, intermittent fasting doesn\u2019t call for calorie counting, which is why it\u2019s such a popular weight loss method for many people. Unfortunately, not counting calories can lead to undereating or overeating, both of which can lead to weight plateauing or weight gain. Use a calorie counter, at least for a while, to better understand how much you should be eating, which will help you with weight loss.<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Lack of Exercise<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Yes, diet alone can help with weight loss. However, diet and increased physical activity offer the best results in both fat and weight loss. Try to exercise for at least 30 minutes a day, 5 days a week through cardio or <a href=\"https:\/\/betterme.world\/articles\/30-minute-weight-workout\/\">strength training<\/a>, or better yet, a mix of both, and you\u2019ll most likely see the desired results.<\/span><\/p>\n<p><a href=\"https:\/\/quiz.betterme.world\/en\/first-page-generated?flow=1443&amp;utm_source=Blog&amp;utm_medium=Blog&amp;utm_campaign=20_Hour_Fasting_Diet\"><img decoding=\"async\" class=\"aligncenter size-large wp-image-82948\" src=\"https:\/\/cdn.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/image-6-1024x640.png\" alt=\"\" width=\"770\" height=\"481\" srcset=\"https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/image-6-1024x640.png 1024w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/image-6-300x188.png 300w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/image-6-768x480.png 768w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/image-6-1720x1075.png 1720w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/11\/image-6.png 1920w\" sizes=\"(max-width: 770px) 100vw, 770px\" \/><\/a><\/p>\n<p><span data-sheets-root=\"1\"><h2><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span><b>Frequently Asked Questions<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2><ul><li><h3><span class=\"ez-toc-section\" id=\"Why_dont_I_feel_hungry_after_a_20-hour_fast\"><\/span><strong>Why don\u2019t I feel hungry after a 20-hour fast?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3><\/li><\/ul><p><span style=\"font-weight: 400;\">This is likely due to some hormonal and metabolic changes in your body.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It has been theorized that in experienced fasters, after many hours of going without food, their hunger and satiety hormones (ghrelin and leptin) have adapted to the routine, which means they\u2019re less likely to feel hungry even after 20 hours of not eating.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some also say that the transition to using ketones instead of glucose in the fasting stage can lead to appetite suppression, which can mean less hunger, even after 20 hours of fasting.\u00a0<\/span><\/p>\n<ul><li><h3><span class=\"ez-toc-section\" id=\"Can_I_drink_coffee_while_fasting\"><\/span><strong>Can I drink coffee while fasting?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3><\/li><\/ul><p><span style=\"font-weight: 400;\">Yes, you can, as long as the coffee in question is unsweetened and without any added cream or milk.\u00a0<\/span><\/p>\n<ul><li><h3><span class=\"ez-toc-section\" id=\"How_long_should_I_fast_to_cleanse_my_body\"><\/span><strong>How long should I fast to cleanse my body?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3><\/li><\/ul><p><span style=\"font-weight: 400;\">You don\u2019t need to fast to cleanse your body.
