As your body depletes these reserves, your blood sugar levels may drop, which could cause feelings of low energy, slight shakiness, or mild irritability (<\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK534877\/\"><span style=\"font-weight: 400;\">2<\/span><\/a><span style=\"font-weight: 400;\">), especially if you are new to fasting.

These symptoms typically result from changes in your blood sugar and hydration status as your body adjusts to using stored energy.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some individuals may also experience dizziness, shakiness, or lightheadedness.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These feelings often improve after you\u2019ve broken your fast, but they\u2019re a signal from your body to monitor how it\u2019s responding and consider whether this type of fasting is right for you.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Pushing yourself too fast if you\u2019re feeling unwell or have ongoing symptoms is not advisable.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Fasting for 24 hours can also be risky if you have certain medical conditions.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example, those with diabetes, especially if taking medication that lowers blood sugar, are at increased risk for hypoglycemia (low blood sugar), which can be dangerous.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">People with a history of eating disorders, those with chronic illnesses, or individuals on multiple medications should avoid fasting or pursue it only with medical supervision.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Children, teens, pregnant or breastfeeding women, and those with a history of malnutrition should avoid fasting.<\/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=24_Hour_Fast_Timeline\"><img decoding=\"async\" class=\"aligncenter size-large wp-image-79363\" src=\"https:\/\/cdn.betterme.world\/articles\/wp-content\/uploads\/2025\/07\/oatmeal-2-1024x640.png\" alt=\"\" width=\"770\" height=\"481\" srcset=\"https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/07\/oatmeal-2-1024x640.png 1024w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/07\/oatmeal-2-300x188.png 300w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/07\/oatmeal-2-768x480.png 768w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/07\/oatmeal-2-1720x1075.png 1720w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2025\/07\/oatmeal-2.png 1920w\" sizes=\"(max-width: 770px) 100vw, 770px\" \/><\/a><\/p>\n<h2 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"What_Not_To_Do_After_A_24-Hour_Fast\"><\/span><strong>What Not To Do After A 24-Hour Fast?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Breaking a 24-hour fast requires careful attention to your body\u2019s needs.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While it may be tempting to indulge in a large or indulgent meal, doing so can lead to digestive discomfort or even undo some of the positive effects of your fast.\u00a0<\/span><\/p>\n<p><b>Here\u2019s what you\u2019ll want to avoid, and what to do instead:<\/b><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Don\u2019t overeat right away.<\/b><span style=\"font-weight: 400;\"> Eating a large quantity of food immediately after fasting can overwhelm your digestive system, potentially causing bloating, cramps, or nausea.
