Let\u2019s take a look at what exactly happens that makes you feel cold.<\/p>\n<h3>Your body is adjusting to using fat for energy<\/h3>\n<p>During intermittent fasting, your body initiates fat burning. Therefore, fat stores are converted into energy. This happens because you\u2019ve been on an empty stomach for a while and there\u2019s no food to take energy from.<\/p>\n<p>This side effect is also an early sign of <a href=\"https:\/\/dofasting.com\/blog\/stages-of-fasting\/\">ketosis<\/a>, but it doesn\u2019t mean that you\u2019re already in a ketosis state. Therefore, feeling cold along with other symptoms of keto will eventually go away once you actually reach ketosis.<\/p>\n<p>This process also can be referred to as fat adaptation which happens when your body goes on a low-carb diet or <a href=\"https:\/\/dofasting.com\/blog\/types-of-fasting\/\">an intermittent fasting plan<\/a>. When you\u2019re fat-adapted, your body will actively burn fat. When this happens depends on your metabolic rate, age, genes, body composition, how <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/21326374\/\">active<\/a> you are, and other factors.<\/p>\n<p>Our bodies contain both <a href=\"https:\/\/www.nih.gov\/news-events\/nih-research-matters\/how-brown-fat-improves-metabolism#:~:text=Brown%20fat%20breaks%20down%20blood,fat%20builds%20up%20in%20obesity.\">brown and white fat<\/a>. Brown fat generates heat by breaking down glucose and molecules, which helps to regulate body temperature. Extra energy is stored in white fat. Obesity causes an accumulation of white fat. Moreover, intermittent fasting aids in the burning of white fat.<\/p>\n<p>The fat adaptation state lasts as long as you eat your first <a href=\"https:\/\/www.cambridge.org\/core\/journals\/british-journal-of-nutrition\/article\/verylowcarbohydrate-ketogenic-diet-v-lowfat-diet-for-longterm-weight-loss-a-metaanalysis-of-randomised-controlled-trials\/6FD9F975BAFF1D46F84C8BA9CE860783\">carb meal<\/a>.

That\u2019s because there\u2019s no need to digest food anymore. Therefore, you\u2019re giving your digestive system a break.<\/p>\n<p>Moreover, your body produces heat by metabolizing food. This is called a <a href=\"https:\/\/www.sciencedirect.com\/topics\/biochemistry-genetics-and-molecular-biology\/thermogenesis#:~:text=Thermogenesis%20is%20defined%20as%20the,adipose%20tissue%20and%20skeletal%20muscle.\">thermogenic response<\/a>. There is no heat created when there is no food to respond to. As a result, you may be feeling chilly.<\/p>\n<p>It takes about <a href=\"https:\/\/www.mayoclinic.org\/digestive-system\/expert-answers\/faq-20058340#:~:text=After%20you%20eat%2C%20it%20takes,move%20through%20the%20entire%20colon.\">6-8 hours<\/a> for your meal to pass through your stomach and small intestine. After that, your food still goes through a <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/24840380\/\">whole gut transit<\/a>. However, if you&#8217;re fasting, you&#8217;re not constantly activating your digestive system by consuming more food, so your gut can rest.<\/p>\n<h3>Your blood flow is redirected<\/h3>\n<p>Adipose<a href=\"https:\/\/www.sciencedirect.com\/topics\/medicine-and-dentistry\/adipose-tissue-blood-flow\"> tissue<\/a> regulates energy supply and demand through hunger and satiety signals. During intermittent fasting, your blood circulation changes direction. Moreover, your blood is moving toward your body\u2019s <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/20518748\/\">fat stores<\/a>. This process is referred to as adipose tissue blood flow.<\/p>\n<p>Feeling cold could indicate that you\u2019re actively burning body fat. Adipose tissue blood flow helps your body use <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/24166067\/#:~:text=Subcutaneous%20adipose%20tissue%20blood%20flow%20(ATBF)%20is%20therefore%20tightly%20linked,markedly%20in%20different%20physiological%20states.\">fat as an energy source<\/a>.<\/p>\n<p>As previously stated, brown fat generates heat and helps with body temperature regulation by breaking down glucose molecules. You can feel cold if the blood flow is redirected away from brown adipose tissue. Nonetheless, your body should adapt and you\u2019ll feel warm again.<\/p>\n<h3>Your blood sugar levels drop<\/h3>\n<p>Intermittent fasting has an effect on <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S193152441400200X\">insulin resistance<\/a>, and therefore, can <a href=\"https:\/\/dofasting.com\/blog\/how-to-lower-blood-sugar\/\">lower your blood sugar levels<\/a>. Some studies suggest that intermittent fasting can also improve <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC8970877\/\">glucose and lipid metabolism<\/a>.<\/p>\n<p>When your blood sugar decreases, you may experience some other symptoms such as <a href=\"https:\/\/www.nhs.uk\/conditions\/low-blood-sugar-hypoglycaemia\/#:~:text=Symptoms%20of%20a%20low%20blood%20sugar%20level&amp;text=sweating,feeling%20hungry\">hunger or dizziness<\/a>, and <a href=\"https:\/\/myhealth.alberta.ca\/Health\/Pages\/conditions.aspx?hwid=rt1054&amp;lang=en-ca\">feeling cold<\/a> can be one of them.<\/p>\n<p>Following a meal, your blood sugar levels rise, and insulin is released, which assists in the use of glucose by cells in your body. On the other hand, when you stay on an empty stomach for some time, your blood sugar levels drop.<\/p>\n<p>The state of having low blood sugar can also be referred to mild hypoglycemia.<\/p>\n<h3>You may be lacking certain nutrients<\/h3>\n<p>Intermittent fasting lowers your calorie intake. You also have a limited amount of time to eat. As a result, getting the necessary vitamins and minerals may be more difficult.<\/p>\n<p>Furthermore, when you fast, you are actively burning fat. There are several fat-soluble vitamins that you may lose along the process.<\/p>\n<p>Certain vitamins and minerals play a role in regulating the heat in your body. Here are some <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/16928474\/\">nutrients<\/a> that you can lose while fasting:<\/p>\n<ul>\n<li aria-level=\"1\">Magnesium \u2014 <a href=\"https:\/\/www.canr.msu.edu\/news\/regulating_your_body_temperature_during_summer_heat#:~:text=Minerals%20that%20help%20keep%20our%20temperature%20gauge%20regulated%3A&amp;text=Magnesium%20%E2%80%93%20Magnesium%20helps%20with%20body,biochemical%20reactions%20in%20the%20body.\">helps regulate body temperature<\/a>.<\/li>\n<li aria-level=\"1\">Selenium \u2014\u00a0converts <a href=\"https:\/\/www.wilsonssyndrome.com\/could-low-selenium-be-contributing-to-your-low-body-temperature\/#:~:text=For%20one%2C%20selenium%20is%20at,thyroid%20blood%20tests%20are%20normal.\">T4 enzyme to T3<\/a>, to maintain normal body temperature.<\/li>\n<li aria-level=\"1\">Zinc \u2014\u00a0helps with <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/22008544\/\">autonomic thermoregulation<\/a>.<\/li>\n<li aria-level=\"1\">Thiamine \u2014 <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/9804367\/\">can help regulate body temperature<\/a>.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"6_Ways_to_Keep_Warm_While_Fasting\"><\/span>6 Ways to Keep Warm While Fasting<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Keep in mind that while fasting, you might feel cold if your body is new to using fat as an energy source. Here are some tips that will help you stay warm on an empty stomach.<\/p>\n<h3>1. Follow the keto diet during your eating window<\/h3>\n<p><a href=\"https:\/\/www.webmd.com\/diet\/ss\/slideshow-ketogenic-diet\">A ketogenic diet<\/a> is a low-carbohydrate diet. The main difference from a normal diet is that you consume mostly proteins and fat and avoid practically all carbs such as sugar, pastries, bread, and soda. Therefore, a keto diet allows no more than <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK499830\/\">20 to 50 grams of carbs<\/a> per day.<\/p>\n<p>In addition, the dietary macronutrients are split into about 55% to 60% fat, 30% to 35% protein, and 5% to 10% carbs.<\/p>\n<p>The diet makes your body go into ketosis. It\u2019s a metabolic state which allows your body to burn fat as an energy source. Fat adaptation happens when your body adjusts to ketosis completely.<\/p>\n<p>Because the main goal of a keto diet is to reach ketosis, it also speeds up fat adaptation and thus eliminates the cold feeling while fasting.<\/p>\n<h3>2. Drink bulletproof coffee<\/h3>\n<p>Instead of having a cup of hot black coffee, try out a bulletproof coffee. Bulletproof coffee combines coffee made from high-quality beans, unsalted butter, and MTC oil. The coffee is extra creamy.<\/p>\n<p>1 cup of bulletproof coffee contains <a href=\"https:\/\/www.fatsecret.co.za\/calories-nutrition\/generic\/bulletproof-coffee?portionid=8127504&amp;portionamount=100.000#:~:text=There%20are%20137%20calories%20in%20100%20ml%20of%20Bulletproof%20Coffee.\">342 calories<\/a>. Keeping that in mind, you can only consume it on your eating window or it will break your fast.<\/p>\n<p>Caffeine and MCT increase metabolic effects and <a href=\"https:\/\/minds.wisconsin.edu\/handle\/1793\/76872\">fat oxidation<\/a>. There is still limited evidence that shows the benefits of bulletproof coffee. Nonetheless, medium-chain triglycerides (MTC) <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/12975635\/\">boost fat-burning<\/a> and speed up the fat adaptation process.<\/p>\n<p>The faster your body becomes fat adapted, the faster you\u2019ll warm up again.<\/p>\n<h3>3. Add healthy fats to your diet<\/h3>\n<p>Fat adaptation requires you to add healthy fats to your diet. Fat doesn\u2019t spike insulin levels as much as carbs. Therefore, eating healthy fats helps you avoid storing fat and remain in a fat-burning mode.<\/p>\n<p>Healthy fats can accelerate fat adaption and thus help you get warm.<\/p>\n<p>Additionally, healthy fats <a href=\"https:\/\/books.google.lt\/books?hl=en&amp;lr=&amp;id=XHlJMN2dfUkC&amp;oi=fnd&amp;pg=PT10&amp;dq=healthy+fats+health+benefits&amp;ots=dZL7J8V-Iu&amp;sig=tauv52h_VNnH2-nYID2vsDsg9HE&amp;redir_esc=y#v=onepage&amp;q=healthy%20fats%20health%20benefits&amp;f=false\">nourish your body<\/a> and promote the efficient functioning of your nerves, brain, hormones, immune system, and metabolism. Examples of healthy and nutritious fats:<\/p>\n<p><a href=\"https:\/\/fdc.nal.usda.gov\/fdc-app.html#\/food-details\/1102652\/nutrients\">Avocados<\/a> \u2014 about 80% fat.<\/p>\n<p><a href=\"https:\/\/www.hsph.harvard.edu\/nutritionsource\/cheese\/#:~:text=The%20nutrients%20in%20cheese%20vary,milligrams%20(mg)%20of%20calcium.\">Cheese<\/a> \u2014\u00a0 is high in vitamin B12, calcium, selenium, and phosphorus.<\/p>\n<p><a href=\"https:\/\/doh.wa.gov\/community-and-environment\/food\/fish\/health-benefits#:~:text=Healthy%20Diet&amp;text=Fish%20is%20filled%20with%20omega,iodine%2C%20magnesium%2C%20and%20potassium.\">Fatty fish<\/a> \u2014 rich in omega-3 fatty acids and proteins.<\/p>\n<p><a href=\"https:\/\/nutritionfacts.org\/topics\/nuts\/\">Nuts<\/a> \u2014 high in antioxidants and omega-3 fatty acids.<\/p>\n<p><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/30538802\/\">Extra virgin olive oil<\/a> \u2014 high in oleic acid.<\/p>\n<p><a href=\"https:\/\/www.hsph.harvard.edu\/nutritionsource\/food-features\/chia-seeds\/#:~:text=Of%20particular%20interest%20by%20researchers,than%20on%20chia%20seeds%20alone.\">Chia seeds<\/a> \u2014 are high in fat and include alpha-linolenic acid (ALA).<\/p>\n<p>Keep in mind that you can only eat these foods during your eating window as they will break your fast.<\/p>\n<h3>4. Exercise \u2013 but don\u2019t overdo it<\/h3>\n<p>Another way to heat your body is to start sweating. Exercise not only helps with fat burning but will also help relieve the feeling of cold during fasting.<\/p>\n<p>During exercise, your body <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/9694408\/\">generates and stores heat<\/a>, elevating core body temperature by a few degrees. However, don\u2019t overdo it. Doing high-intensity workouts during a fast can make you feel light-headed and nauseous.<\/p>\n<p>Also, burning too many calories can leave you feeling extremely hungry and unable to stick with your fasting routine. Instead of making your body burn, consider doing these exercises:<\/p>\n<p>Walking<\/p>\n<p>Cycling<\/p>\n<p>Hiking<\/p>\n<p>Swimming<\/p>\n<p>Yoga<\/p>\n<p>Pilates<\/p>\n<p>The <a href=\"https:\/\/dofasting.com\/\">DoFasting app<\/a> allows you to practice light-intensity home workouts. It&#8217;s a fasting app with everything you need to have the best intermittent fasting experience. A separate fitness section provides a range of simple, beginner-friendly workouts that you may practice at any time.<\/p>\n<p>You should try to be active for at least <a href=\"https:\/\/www.mayoclinic.org\/healthy-lifestyle\/weight-loss\/in-depth\/exercise\/art-20050999\">30 minutes<\/a> every day to see results.<\/p>\n\n    <div class=\"cta-shortcode__wrap\">\n        <section class=\"cta-shortcode blue\" >\n\n                            <h3>Take a <br \/>\r\n1-minute quiz<\/h3>\n                                        <h5>and discover how much weight you can lose with DoFasting!<\/h5>\n                                        <div class=\"actions two-buttons\">\n                                                                    <a class=\"btn blue\" href=\"https:\/\/new.dofasting.com\/simple?utm_source=google&utm_medium=organic&utm_campaign=blue_blog_post_cta_male\" target=\"_blank\">MALE<\/a>\n                                                                    <a class=\"btn pink\" href=\"https:\/\/new.dofasting.com\/simple?utm_source=google&utm_medium=organic&utm_campaign=blue_blog_post_cta_female\" target=\"_blank\">FEMALE<\/a>\n                                    <\/div>\n                        <img width=\"326\" height=\"446\" src=\"https:\/\/dofasting.com\/blog\/app\/uploads\/2022\/11\/mockup-6-new.png\" class=\"cta-img wp-post-image\" alt=\"\" decoding=\"async\" srcset=\"https:\/\/dofasting.com\/blog\/app\/uploads\/2022\/11\/mockup-6-new.png 326w, https:\/\/dofasting.com\/blog\/app\/uploads\/2022\/11\/mockup-6-new-219x300.png 219w\" sizes=\"(max-width: 326px) 100vw, 326px\" \/>        <\/section>\n    <\/div>\n\n\n<h3>5. Replenish your lost nutrients<\/h3>\n<p>In the best-case scenario, your first meal after a fast should have nutrient-rich foods and enough electrolytes. When intermittent fasting, you consume fewer calories and that might also mean that you consume fewer vitamins and minerals.<\/p>\n<p>This is why it is critical to include nutrient-rich foods and electrolytes in your diet. <a href=\"https:\/\/www.tandfonline.com\/doi\/abs\/10.1080\/10408399609527748\">Low iron levels<\/a>, for example, have an effect on the thyroid, making it less efficient at producing the heat that your body requires.<\/p>\n<p>Low iron levels can also impair circulation and disrupt blood flow, resulting in a loss of warmth. This can also lead to vitamin B12 deficiency that helps generate red blood cells.<\/p>\n<p>Having enough <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/9804367\/\">thiamine<\/a> can also help regulate body temperature. Also, electrolytes play an important role in a lot of functions in your body. To specify, <a href=\"https:\/\/www.canr.msu.edu\/news\/regulating_your_body_temperature_during_summer_heat#:~:text=Minerals%20that%20help%20keep%20our%20temperature%20gauge%20regulated%3A&amp;text=Electrolytes%20affect%20the%20amount%20of,helps%20with%20body%20temperature%20regulation.\">magnesium<\/a> is an electrolyte that helps regulate body temperature.<\/p>\n<p>Foods to include in your diet to replenish your lost nutrients:<\/p>\n<p>Dark leafy greens<\/p>\n<p>Whole grains<\/p>\n<p>Fish and seafood<\/p>\n<p>Lean meat<\/p>\n<p>Nuts<\/p>\n<p>Dairy<\/p>\n<p>Fruits and vegetables<\/p>\n<p>To make sure that you\u2019re really getting the needed vitamins and minerals, you could also take supplements. Also, it\u2019s important to always <a href=\"https:\/\/dofasting.com\/blog\/what-can-drink-during-intermittent-fasting\/\">stay hydrated<\/a>.<\/p>\n<h3>6. Take a hot bath or shower<\/h3>\n<p>If you get cold during fasting, a hot bath or shower is an easy solution. Allowing your limbs to warm up in hot water can help regulate your body temperature altogether.<\/p>\n<p>A hot bath or a shower can activate the body\u2019s thermoregulatory system and even improve your <a href=\"https:\/\/www.tandfonline.com\/doi\/full\/10.3109\/0886022X.2013.832318\">blood pressure<\/a>.<\/p>\n<p>It doesn\u2019t really matter when you take a bath or a shower. However, if you take one in the evening, it can also improve <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/31102877\/\">the quality of your sleep<\/a>.<\/p>\n<p>Overall, soaking yourself in hot water for a few moments might be the quickest and easiest way to warm up your body, in addition to being an enjoyable relaxing experience.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Signs_of_Complete_Fat_Adaptation\"><\/span>Signs of Complete Fat Adaptation<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Aside from not being cold anymore, you may experience additional symptoms after you have fat adapted.<\/p>\n<h3>Decreased cravings and hunger<\/h3>\n<p>Ketogenic diets do <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/25402637\/\">suppress appetite<\/a> and can reduce hunger pangs. However, there is limited evidence that fat adaptation leads to decreased hunger and cravings.<\/p>\n<p>According to one <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6213862\/\">study<\/a> published in 2018, adopting a keto diet leads to lower food cravings, thus fat adaption might let you go without food for a little longer.
