Sometimes the numbers are high and sometimes they\u2019re what you expect to see. Here\u2019s why the scale tips to both extremes throughout the day:<\/span><\/p>\n<h3 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Water_Retention\"><\/span><b>Water Retention<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Water retention is one of the major culprits of daily weight fluctuation. Here are some significant causes of water retention (<\/span><a href=\"https:\/\/www.medicalnewstoday.com\/articles\/weight-fluctuation\"><span style=\"font-weight: 400;\">2<\/span><\/a><span style=\"font-weight: 400;\">):<\/span><\/p>\n<h3 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"High_Sodium_Consumption\"><\/span><b>High Sodium Consumption<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Sodium, or salt, is crucial in our bodies as it helps regulate blood pressure, transport nutrients, and balance water levels in the body. However, too much of it makes you retain more fluids, which leads to an increase in the number you see on the scale (<\/span><a href=\"https:\/\/www.actiononsalt.org.uk\/salthealth\/salt-and-water-retention\/#:~:text=When%20we%20eat%20too%20much,of%20sodium%20in%20the%20urine.\"><span style=\"font-weight: 400;\">9<\/span><\/a><span style=\"font-weight: 400;\">).\u00a0<\/span><\/p>\n<h3 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Dehydration\"><\/span><b>Dehydration<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">It\u2019s important to drink enough water every day to avoid getting dehydrated. If you don\u2019t drink enough water, your body stores water to avoid dehydration (<\/span><a href=\"https:\/\/www.medicalnewstoday.com\/articles\/weight-fluctuation\"><span style=\"font-weight: 400;\">6<\/span><\/a><span style=\"font-weight: 400;\">). As a consequence, you retain water, which may see your weight increase throughout the day, depending on your water consumption\u00a0 (<\/span><a href=\"https:\/\/www.medicalnewstoday.com\/articles\/187978\"><span style=\"font-weight: 400;\">12<\/span><\/a><span style=\"font-weight: 400;\">).\u00a0<\/span><\/p>\n<h3 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Your_Diet\"><\/span><b>Your Diet<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Your weight is also highly influenced by what you eat throughout the day. Your energy balances between what you eat and what you burn, affecting your weight over time. If you eat more than your body is burning, you\u2019re likely to gain weight(<\/span><a href=\"https:\/\/www.webmd.com\/diet\/ss\/slideshow-reasons-weight-changes\"><span style=\"font-weight: 400;\">8<\/span><\/a><span style=\"font-weight: 400;\">).\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Remember that weight loss is not easy. To lose one pound, the Mayo Clinic suggests that you\u2019ll need to consume around 500 fewer calories each day for a week and\/or burn these extra calories through exercise (<\/span><a href=\"https:\/\/www.mayoclinic.org\/healthy-lifestyle\/weight-loss\/in-depth\/calories\/art-20048065\"><span style=\"font-weight: 400;\">2<\/span><\/a><span style=\"font-weight: 400;\">). Contrary to what you may think, this is not easy.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To avoid weight gain caused by your diet, you should talk to your registered dietitian to develop a meal plan that can help you maintain a healthy weight. Similarly, these professionals can also help you craft a <a href=\"https:\/\/betterme.world\/articles\/weight-loss-smoothies\/\">weight loss diet plan<\/a> if your goal is to lose weight.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Although there are many such <a href=\"https:\/\/betterme.world\/articles\/calorie-deficit-meal-plan\/\">meal plans<\/a> online, we don\u2019t advise you to start them without seeking professional help.\u00a0<\/span><\/p>\n<p><a href=\"https:\/\/quiz.betterme.world\/first-page-generated?flow=2228&amp;utm_source=Blog&amp;utm_medium=Blog&amp;utm_campaign=why_does_my_weight_fluctuate_10_lbs_in_a_day\"><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/cdn.betterme.world\/articles\/wp-content\/uploads\/2025\/03\/collage-8.png\" \/>\u00a0<\/a><\/p>\n<h2 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"How_You_Weigh_Yourself\"><\/span><b>How You Weigh Yourself<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The manner in which you weigh yourself may also lead to weight fluctuation throughout the day. There are several factors you must consider when weighing yourself, including your outfit, weight distribution on your feet, and where you place your scale (<\/span><a href=\"https:\/\/www.webmd.com\/diet\/ss\/slideshow-reasons-weight-changes\"><span style=\"font-weight: 400;\">8<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Firstly, you should always place your scale on a hard surface, preferably the same surface every time. Also, when you weigh yourself, dress in light clothing and do the same every time you step on the scale. In addition, stand on both feet and make sure your weight is evenly distributed on both feet.\u00a0<\/span><\/p>\n<p><strong>If you tend to let yourself off the hook, raise the white flag when things get tougher than you expected, send yourself on an unconscious binge-eating trip \u2013 <a href=\"https:\/\/quiz.betterme.world\/first-page-generated?flow=2228&amp;utm_source=Blog&amp;utm_medium=Blog&amp;utm_campaign=why_does_my_weight_fluctuate_10_lbs_in_a_day\">BetterMe app is here to help you <\/a> leave all of these sabotaging habits in the past!<\/strong><\/p>\n<h2 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"When_You_Weigh_Yourself\"><\/span><b>When You Weigh Yourself<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">In addition to how you weigh yourself, the time of day when you weigh yourself also accounts for the weight fluctuation. You\u2019ll always get different results when you weigh yourself in the morning, afternoon, and evening.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Experts suggest you weigh yourself in the morning for the most accurate result (<\/span><a href=\"https:\/\/www.webmd.com\/diet\/ss\/slideshow-reasons-weight-changes\"><span style=\"font-weight: 400;\">8<\/span><\/a><span style=\"font-weight: 400;\">). This is because at this time, you probably haven\u2019t had anything to eat or drink. However, during the day, your scale will change after you eat and drink. So, if you always weigh yourself first thing in the morning, you\u2019ll be able to more accurately identify trends, such as weight loss or gain over time.\u00a0<\/span><\/p>\n<h2 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Frequency_of_Your_Bathroom_Breaks\"><\/span><b>Frequency of Your Bathroom Breaks<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Believe it or not, your weight fluctuation is also affected by the number of times you visit the bathroom. If you eat a big meal and then weigh yourself, you may weigh more. This is caused by the fecal weight of the food waste you haven\u2019t yet excreted (<\/span><a href=\"https:\/\/www.webmd.com\/diet\/ss\/slideshow-reasons-weight-changes\"><span style=\"font-weight: 400;\">8<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Similarly, if you drink a lot of fluid, you\u2019ll see increased weight. This is due to urine buildup. On the other hand, if you just emptied your bladder or bowels or have lost fluid due to diarrhea or vomiting and weigh yourself, you\u2019ll see a lower number (<\/span><a href=\"https:\/\/www.webmd.com\/diet\/ss\/slideshow-reasons-weight-changes\"><span style=\"font-weight: 400;\">8<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<p><a href=\"https:\/\/quiz.betterme.world\/first-page-generated?flow=2228&amp;utm_source=Blog&amp;utm_medium=Blog&amp;utm_campaign=why_does_my_weight_fluctuate_10_lbs_in_a_day\"><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/cdn.betterme.world\/articles\/wp-content\/uploads\/2025\/04\/Collage-Walking-4-2.png\" \/><\/a><\/p>\n<h3 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Exercise\"><\/span><b>Exercise<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Exercising is essential as it reduces the risk of various conditions, improves overall health, and promotes weight loss. According to WebMD, some athletes are reported to drop 6% to 10% of their body weight after a workout due to the loss of fluid from sweating (<\/span><a href=\"https:\/\/www.webmd.com\/diet\/ss\/slideshow-reasons-weight-changes\"><span style=\"font-weight: 400;\">8<\/span><\/a><span style=\"font-weight: 400;\">).

Don\u2019t stop this drug treatment if you suspect it\u2019s responsible for your weight gain. Instead, talk to your doctor and tell them your concerns. They may recommend another drug alternative or other strategies to counter the negative effects.\u00a0<\/span><a href=\"https:\/\/quiz.betterme.world\/first-page-generated?flow=2228&amp;utm_source=Blog&amp;utm_medium=Blog&amp;utm_campaign=why_does_my_weight_fluctuate_10_lbs_in_a_day\">\u00a0<\/a><\/p>\n<h3 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Steroids\"><\/span><b>Steroids<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Some anti-inflammatory steroid medications such as prednisone result in weight gain (<\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK537590\/\"><span style=\"font-weight: 400;\">5<\/span><\/a><span style=\"font-weight: 400;\">).

Similarly, they also increase your appetite, making you consume more calories.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Despite this effect, experts don\u2019t advise you to suddenly stop taking steroids if you\u2019ve been taking them. This may lead to more severe problems, which is why you need to check with your doctor first.<\/span><\/p>\n<h3 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Antipsychotic_Drugs\"><\/span><b>Antipsychotic Drugs<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">These are medications that are used to treat psychiatric mental disorders such as bipolar disorder and schizophrenia (<\/span><a href=\"https:\/\/www.webmd.com\/diet\/ss\/slideshow-weight-gain-shockers\"><span style=\"font-weight: 400;\">4<\/span><\/a><span style=\"font-weight: 400;\">).

Some of these conditions are:<\/span><\/p>\n<h3 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Polycystic_Ovary_Syndrome_PCOS\"><\/span><b>Polycystic Ovary Syndrome (PCOS)<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">One of the many health conditions that results in female weight gain is PCOS. This is a hormonal problem among women of childbearing age where many small cysts grow on their ovaries (<\/span><a href=\"https:\/\/www.webmd.com\/diet\/ss\/slideshow-weight-gain-shockers\"><span style=\"font-weight: 400;\">10<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The condition leads to hormonal imbalances, which have several side effects such as weight gain, irregular menstruation cycles, hair loss, excessive hair on the chest, back, or abdomen, and acne (<\/span><a href=\"https:\/\/www.medicalnewstoday.com\/articles\/324872\"><span style=\"font-weight: 400;\">11<\/span><\/a><span style=\"font-weight: 400;\">).\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Unfortunately, there is no cure for this condition. However, doctors recommend women with PCOS to adopt lifestyle changes such as exercising and eating a healthy diet to ease the symptoms (<\/span><a href=\"https:\/\/www.medicalnewstoday.com\/articles\/324872\"><span style=\"font-weight: 400;\">11<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<h3 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Hypothyroidism\"><\/span><b>Hypothyroidism<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Hypothyroidism is a condition where your thyroid gland doesn\u2019t produce enough thyroid hormone. If your thyroid doesn\u2019t make enough thyroid hormone, you\u2019ll feel weak, tired, cold, and end up gaining weight (<\/span><a href=\"https:\/\/www.webmd.com\/diet\/ss\/slideshow-weight-gain-shockers\"><span style=\"font-weight: 400;\">10<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Similarly, WebMD acknowledges that your metabolism slows down, which means you\u2019re burning calories at a slower rate than usual(<\/span><a href=\"https:\/\/www.webmd.com\/obesity\/ss\/slideshow-slow-metabolism\"><span style=\"font-weight: 400;\">1<\/span><\/a><span style=\"font-weight: 400;\">). A slow metabolism results in weight gain as you\u2019re burning fewer calories than you consume. The only way you can reverse weight gain caused by hypothyroidism is to get treated for it.\u00a0<\/span><\/p>\n<h3 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Kidney_Problems\"><\/span><b>Kidney Problems<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Sudden weight gain may reflect kidney problems if accompanied by other symptoms of kidney disease. If your kidneys are not operating efficiently, your body may retain water, which contributes to weight gain.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Kidney problems can lead to water retention as the kidneys are responsible for removing fluids and excess water from the body (<\/span><a href=\"https:\/\/www.medicalnewstoday.com\/articles\/324872\"><span style=\"font-weight: 400;\">11<\/span><\/a><span style=\"font-weight: 400;\">) (<\/span><a href=\"https:\/\/www.medicalnewstoday.com\/articles\/187978\"><span style=\"font-weight: 400;\">12<\/span><\/a><span style=\"font-weight: 400;\">).

The condition occurs when your body produces too much cortisol over an extensive duration (<\/span><a href=\"https:\/\/www.mayoclinic.org\/diseases-conditions\/cushing-syndrome\/symptoms-causes\/syc-20351310#:~:text=Without%20treatment%2C%20Cushing%20syndrome%20can,cortisol%20for%20a%20long%20time.\"><span style=\"font-weight: 400;\">4<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Cortisol is the hormone that offers your body the ability to respond to stress. It is incredibly rare to develop this disease without an external trigger. However, it\u2019s a major side effect of taking glucocorticoids. These are drugs that are used to treat asthma, systemic lupus erythematosus, and rheumatoid arthritis (<\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK537590\/\"><span style=\"font-weight: 400;\">5<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<h2 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"When_to_See_a_Doctor\"><\/span><b>When to See a Doctor<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Some causes of weight loss or weight gain are not alarming. Your weight will naturally vary throughout the day, and weight fluctuations are affected by how and when you weigh yourself. In such cases, there\u2019s no need to see a doctor. All you need to do is re-adjust and learn when and how to weigh yourself for accurate results (<\/span><a href=\"https:\/\/www.webmd.com\/diet\/ss\/slideshow-reasons-weight-changes\"><span style=\"font-weight: 400;\">1<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, you should contact your doctor if you experience rapid and unintentional weight changes without any obvious cause.

In fact, such rapid changes in weight can be detrimental to your health and may be a sign of an underlying medical condition. While our bodies can fluctuate in weight by a few pounds due to water retention or digestion, gaining or losing 10 pounds in a day is not typical.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It\u2019s normal to see gradual weight changes over time, usually within a range of 1-2 pounds per week. This is considered to be a healthy and sustainable rate of weight loss or gain (<\/span><a href=\"https:\/\/www.cdc.gov\/healthyweight\/losing_weight\/index.html\"><span style=\"font-weight: 400;\">7<\/span><\/a><span style=\"font-weight: 400;\">). Rapid weight fluctuations can put stress on your organs, disrupt hormone levels, and even affect your mental health.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you find yourself experiencing such drastic changes in weight, it&#8217;s important to consult a healthcare provider to rule out any underlying health issues. They can also help you develop a safe and sustainable plan for managing your weight.<\/span><\/p>\n<ul><li><h3><span class=\"ez-toc-section\" id=\"Does_10-pound_weight_gain_show_on_the_face\"><\/span><strong>Does 10-pound weight gain show on the face?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3><\/li><\/ul><p><span style=\"font-weight: 400;\">10-pound weight gain can definitely show on your face. Facial appearance is closely linked to overall body composition, and any significant changes in weight can affect the way you look. When you gain weight, particularly in the form of fat, it tends to accumulate all over your body, including the face.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This added fat can lead to puffiness and bloating in the face, which makes it appear rounder and fuller. Furthermore, weight gain can also affect the distribution of fat in the face, causing changes in cheekbone definition and jawline appearance. So even though a 10-pound gain may not seem like much in terms of overall body weight, it can definitely have an impact on your facial features.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">At the same time, water weight and bloating can also contribute to facial changes, particularly due to medical conditions that cause fluid retention (<\/span><a href=\"https:\/\/www.medicalnewstoday.com\/articles\/187978\"><span style=\"font-weight: 400;\">12<\/span><\/a><span style=\"font-weight: 400;\">). This may cause temporary swelling or puffiness in the face, which can make it appear slightly larger than usual. If you\u2019re experiencing increased swelling due to fluid retention, you should talk to your healthcare provider.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We have tips for resolving this in our blog: <a href=\"https:\/\/betterme.world\/articles\/how-to-lose-water-weight\/\">How to Lose Water Weight<\/a>.<\/span><\/p>\n<ul><li><h3><span class=\"ez-toc-section\" id=\"How_much_weight_is_it_normal_to_gain_overnight\"><\/span><strong>How much weight is it normal to gain overnight?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3><\/li><\/ul><p><span style=\"font-weight: 400;\">It&#8217;s normal to see a 1-2 pound change in weight overnight due to fluctuations in water retention and digestion (<\/span><a href=\"https:\/\/www.medicalnewstoday.com\/articles\/187978\"><span style=\"font-weight: 400;\">12<\/span><\/a><span style=\"font-weight: 400;\">). However, anything significantly beyond this range may indicate a larger issue at play.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example, gaining 5 pounds overnight can be a sign of fluid retention, which could be caused by factors such as consuming too much salt or dehydration (<\/span><a href=\"https:\/\/www.medicalnewstoday.com\/articles\/187978\"><span style=\"font-weight: 400;\">12<\/span><\/a><span style=\"font-weight: 400;\">). At the same time, losing several pounds overnight may be a sign of dehydration, excessive sweating, or a gastrointestinal illness.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Weight can naturally fluctuate throughout the day and it&#8217;s not uncommon to see these fluctuations reflected on the scale. However, significant changes in weight overnight should not be dismissed and may warrant further investigation from a medical professional.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Our blog, <a href=\"https:\/\/betterme.world\/articles\/how-to-get-rid-of-water-retention-overnight\/\">How to Get Rid of Water Retention Overnight<\/a>, has tips for managing water weight and bloating.<\/span><\/p>\n<ul><li><h3><span class=\"ez-toc-section\" id=\"Can_you_gain_10_lbs_of_water_weight_in_a_day\"><\/span><strong>Can you gain 10 lbs of water weight in a day?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3><\/li><\/ul><p><span style=\"font-weight: 400;\">No, you\u2019re not likely to gain 10 pounds of water weight in a day. Your body can only retain so much water before it reaches a state of equilibrium and eliminates the excess through urination or sweating.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Excess fluid retention may be caused by certain medical conditions such as heart or kidney disease, or by external factors such as consuming too much salt or taking certain medications (<\/span><a href=\"https:\/\/www.medicalnewstoday.com\/articles\/187978\"><span style=\"font-weight: 400;\">12<\/span><\/a><span style=\"font-weight: 400;\">). However, even in these cases, it would be highly unlikely to see a 10-pound increase in water weight in a day. Talk to your healthcare provider about how much weight fluctuation from water retention you should expect, and when you should seek medical attention. <\/span><\/p>\n\n<p><span data-sheets-root=\"1\" data-sheets-value=\"{&quot;1&quot;:2,&quot;2&quot;:&quot;&lt;a href=&quot;&quot;https:\/\/quiz.betterme.world\/first-page-generated?flow=2228&amp;utm_source=Blog&amp;utm_medium=Blog&amp;utm_campaign=why_does_my_weight_fluctuate_10_lbs_in_a_day&quot;&quot; target=&quot;_blank&quot;&gt;&lt;video autoplay=&quot;autoplay&quot; loop=&quot;loop&quot; muted=&quot;muted&quot; playsinline=&quot;playsinline&quot; width=&quot;777&quot;&gt;&lt;source src=&quot;&quot;https:\/\/cdn.betterme.world\/articles\/wp-content\/uploads\/2023\/06\/ezgif.com-gif-to-mp4-1.mp4&quot;&quot; type=&quot;video\/mp4&quot; \/&gt;&lt;\/video&gt;&lt;\/a&gt;&quot;}\" data-sheets-userformat=\"{&quot;2&quot;:256,&quot;11&quot;:3}\" data-sheets-formula=\"=replace(R[-12]C[0],SEARCH(&quot;LINK TO QUIZ&quot;,R[-12]C[0]),LEN(&quot;LINK TO QUIZ&quot;),R8C[0])\"><a href=\"https:\/\/quiz.betterme.world\/first-page-generated?flow=2228&amp;utm_source=Blog&amp;utm_medium=Blog&amp;utm_campaign=why_does_my_weight_fluctuate_10_lbs_in_a_day\" target=\"_blank\"><video autoplay=\"autoplay\" loop=\"loop\" muted=\"muted\" playsinline=\"playsinline\" width=\"777\"><source src=\"https:\/\/cdn.betterme.world\/articles\/wp-content\/uploads\/2023\/06\/ezgif.com-gif-to-mp4-1.mp4\" type=\"video\/mp4\" \/><\/video><\/a><\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_Bottom_Line\"><\/span><b>The Bottom Line<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Why does my weight fluctuate 10 lbs in a day?
