We all know the common narrative: burn the midnight oil, and you\u2019ll pack on the pounds. It&#39;s drilled into us. Stress eating, late-night snacks, a slowed metabolism\u2014it&#39;s the classic recipe for weight gain. But what about the other side of the coin? Can lack of sleep cause weight loss?<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The short answer is yes, it can. But it\u2019s absolutely not the kind of weight loss anyone should ever aim for. It&#39;s a complicated, physiologically damaging process that trades a number on the scale for your overall health. Our team has spent years studying the intricate dance between hormones, metabolism, and weight, and the relationship with sleep is one of the most critical and misunderstood. Let\u2019s pull back the curtain on what&#39;s really happening in your body when you&#39;re chronically underslept.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">So, What&#39;s the Real Answer? Can You Lose Weight From Poor Sleep?<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Yes, in some specific, short-term scenarios, significant sleep deprivation can lead to a temporary drop on the scale. We can&#39;t stress this enough: this is not a good thing. It\u2019s a sign that your body is in a state of distress, and the weight you\u2019re losing is likely the wrong kind\u2014we\u2019re talking precious muscle mass and water, not body fat.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Think about it. When your body is under duress, it kicks into survival mode. A sudden, intense period of sleeplessness\u2014maybe from a grueling project at work or caring for a newborn\u2014can trigger a massive stress response. This response revs up your system in some ways while breaking it down in others. Your body starts burning more energy just to stay awake and function at a basic level. This increased energy expenditure, combined with a potential decrease in appetite that sometimes accompanies acute stress or illness, can result in weight loss.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">But this is a dangerous illusion of progress.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">What you&#39;re witnessing isn&#39;t healthy fat metabolism. It&#39;s your body cannibalizing its own resources to cope with a perceived threat. This is a critical distinction that gets lost in the simple focus on the number on the scale. In our experience helping clients navigate complex weight loss journeys, we&#39;ve found that understanding <em style=\"font-style: italic; color: inherit;\">what<\/em> you&#39;re losing is infinitely more important than just seeing the number go down.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">The Hormonal Chaos: How Sleep Deprivation Rewires Your Body<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">To really grasp why sleepless weight loss is a red flag, we have to talk about hormones. Sleep is your body&#39;s prime time for hormonal regulation. It\u2019s when the command center in your brain resets everything for the next day. When you rob it of that time, you unleash chaos.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Two of the biggest players in the appetite game are ghrelin and leptin. Think of them as the &#39;go&#39; and &#39;stop&#39; signals for hunger.<\/p>\n<ul style=\"font-size: 18px; line-height: 1.8; margin: 1.5em 0; padding-left: 2.5em; list-style-type: disc;\">\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\"><strong style=\"font-weight: 700; color: inherit;\">Ghrelin:<\/strong> This is the &#39;hunger hormone.&#39; It\u2019s produced in your stomach and signals your brain that it\u2019s time to eat. When you\u2019re sleep-deprived, your body produces more ghrelin. Suddenly, you&#39;re getting stronger, more frequent signals to eat, especially high-calorie, high-carbohydrate foods.<\/li>\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\"><strong style=\"font-weight: 700; color: inherit;\">Leptin:<\/strong> This is the &#39;satiety hormone.&#39; It\u2019s produced by your fat cells and tells your brain, &#39;We&#39;re full, you can stop eating now.&#39; When you don\u2019t get enough sleep, your leptin levels plummet. Not only are you getting more &#39;go&#39; signals from ghrelin, but the &#39;stop&#39; signal from leptin is barely a whisper.<\/li>\n<\/ul>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Now, you might think this hormonal state would only lead to weight <em style=\"font-style: italic; color: inherit;\">gain<\/em>, and you&#39;re right\u2014that&#39;s the most common long-term outcome. However, in the short-term, another hormone enters the ring and complicates everything: cortisol.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Cortisol, the infamous stress hormone, skyrockets when you&#39;re sleep-deprived. It\u2019s part of your body&#39;s &#39;fight or flight&#39; system. Cortisol&#39;s job is to mobilize energy for immediate use, which it does by breaking down tissues\u2014including muscle\u2014to release glucose into your bloodstream. So while your appetite-regulating hormones might be screaming for you to eat, your stress response is simultaneously burning through your body&#39;s resources at an accelerated and destructive rate. It\u2019s a physiological civil war, and you\u2019re caught in the middle.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Muscle vs. Fat: The Unseen Cost of Sleepless Weight Loss<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">This is where we get to the core of the problem. When you lose weight from being sick or severely sleep-deprived, your body doesn&#39;t preferentially burn fat. In fact, it does the opposite. In a high-cortisol state, your body desperately wants to hold onto its fat stores (its emergency energy reserve) and will instead break down muscle tissue for quick energy. This process is called catabolism.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Why is this so bad? Your muscle mass is your metabolic engine. It burns calories even when you&#39;re at rest. Every pound of muscle you lose lowers your basal metabolic rate (BMR), making it harder to manage your weight in the long run. So, the scale might show a lower number, but you\u2019ve actually made your body less efficient at burning fat. You&#39;ve won a battle but are setting yourself up to lose the war.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">We\u2019ve seen it time and time again. Someone comes to us frustrated because they lost 10 pounds through a punishing schedule, only to gain back 15 as soon as they returned to a normal routine. That&#39;s because they didn&#39;t lose 10 pounds of fat; they lost 5 pounds of muscle and 5 pounds of water, crippling their metabolism in the process. When they started eating normally again, their body, now with a slower metabolic engine, stored those calories as fat more readily than before.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">It&#39;s a truly vicious cycle.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Here&#39;s a simple breakdown of how sleep impacts your body composition, which is a far more important metric than just your weight.<\/p>\n<table>\n<thead>\n<tr>\n<th align=\"left\">Feature<\/th>\n<th align=\"left\">Healthy, Restful Sleep (7-9 hours)<\/th>\n<th align=\"left\">Chronic Sleep Deprivation (&lt;6 hours)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td align=\"left\"><strong style=\"font-weight: 700; color: inherit;\">Hormone Balance<\/strong><\/td>\n<td align=\"left\">Ghrelin &amp; leptin are regulated, promoting normal appetite signals.<\/td>\n<td align=\"left\">Ghrelin (hunger) surges; leptin (satiety) plummets.<\/td>\n<\/tr>\n<tr>\n<td align=\"left\"><strong style=\"font-weight: 700; color: inherit;\">Cortisol Levels<\/strong><\/td>\n<td align=\"left\">Cortisol follows a natural rhythm, lowest during sleep.<\/td>\n<td align=\"left\">Cortisol is chronically elevated, promoting a stress state.<\/td>\n<\/tr>\n<tr>\n<td align=\"left\"><strong style=\"font-weight: 700; color: inherit;\">Muscle Maintenance<\/strong><\/td>\n<td align=\"left\">Promotes muscle repair and growth (anabolism).<\/td>\n<td align=\"left\">Promotes muscle breakdown for energy (catabolism).<\/td>\n<\/tr>\n<tr>\n<td align=\"left\"><strong style=\"font-weight: 700; color: inherit;\">Fat Storage<\/strong><\/td>\n<td align=\"left\">Encourages the body to use fat for energy.<\/td>\n<td align=\"left\">Encourages the body to store fat, especially visceral belly fat.<\/td>\n<\/tr>\n<tr>\n<td align=\"left\"><strong style=\"font-weight: 700; color: inherit;\">Metabolic Rate<\/strong><\/td>\n<td align=\"left\">Maintains a healthy, stable basal metabolic rate.<\/td>\n<td align=\"left\">Initially may increase BMR, but long-term leads to a slower metabolism due to muscle loss.<\/td>\n<\/tr>\n<tr>\n<td align=\"left\"><strong style=\"font-weight: 700; color: inherit;\">Cravings<\/strong><\/td>\n<td align=\"left\">Cravings are manageable and aligned with nutritional needs.<\/td>\n<td align=\"left\">Intense cravings for high-sugar, high-fat, processed foods.<\/td>\n<\/tr>\n<tr>\n<td align=\"left\"><strong style=\"font-weight: 700; color: inherit;\">Weight Outcome<\/strong><\/td>\n<td align=\"left\">Supports sustainable fat loss and healthy weight management.<\/td>\n<td align=\"left\">Can cause temporary weight (muscle\/water) loss, but promotes long-term fat gain.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Looking at this table, the choice becomes crystal clear. The path of sleep deprivation is a path toward a weaker, less healthy, and ultimately fatter body, even if the scale temporarily tells a different story.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">The Stress Connection: Cortisol&#39;s Double-Edged Sword<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Let\u2019s dive a bit deeper into cortisol because it\u2019s so central to this entire discussion. In small, timely bursts, cortisol is essential. It wakes you up in the morning and gives you the energy to handle a stressful situation. The problem is that a lack of sleep doesn&#39;t create a small burst; it creates a relentless, high-level flood of cortisol that never subsides.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">This chronically high cortisol level does two devastating things related to your weight:<\/p>\n<ol style=\"font-size: 18px; line-height: 1.8; margin: 1.5em 0; padding-left: 2.5em;\">\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\"><strong style=\"font-weight: 700; color: inherit;\">It Promotes Muscle Breakdown:<\/strong> As we mentioned, cortisol signals the body to break down protein in your muscles to create glucose. It&#39;s an emergency energy-release mechanism. This is the primary driver behind the &#39;weight loss&#39; seen from extreme sleep deprivation.<\/li>\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\"><strong style=\"font-weight: 700; color: inherit;\">It Encourages Visceral Fat Storage:<\/strong> Here\u2019s the cruel irony. While cortisol is breaking down your calorie-burning muscle, it&#39;s also telling your body to store any excess calories as fat, specifically visceral fat. This is the dangerous, metabolically active fat that wraps around your internal organs and is strongly linked to chronic diseases like type 2 diabetes and heart disease.<\/li>\n<\/ol>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">So you&#39;re losing the good stuff (muscle) and gaining the worst possible stuff (visceral fat). It&#39;s the worst trade-off imaginable for your health. This is why our team at TrimrX focuses on holistic, medically-supervised approaches. We understand that true health isn&#39;t just about weight loss; it&#39;s about improving body composition and reducing the metabolic risks associated with conditions like obesity. It\u2019s about tackling the hormonal imbalances that drive these dangerous patterns, which is where modern treatments can be so effective.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">A Look at Metabolism: Does It Speed Up or Slow Down?<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">This is another area of common confusion. Some studies have shown that in the very acute phase of sleep deprivation (like pulling one all-nighter), your resting metabolic rate can actually increase slightly. Your body is working so hard and is so stressed just staying awake that it burns more calories to do so.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">This is the kernel of truth that gets twisted into the myth that &#39;lack of sleep can help you lose weight.&#39;<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">But this effect is fleeting and comes at an enormous cost. This temporary metabolic uptick is fueled by the breakdown of your muscle tissue. A car can go faster if you start throwing the seats and doors into the engine for fuel, but you won&#39;t have a functional car for very long. That&#39;s exactly what your body is doing.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Over the long term, the effect flips entirely. As you continue to lose muscle mass from chronic sleep deprivation and elevated cortisol, your basal metabolic rate steadily declines. Your body becomes less and less efficient. This, combined with the hormonal drive to eat more high-calorie foods, is the definitive recipe for long-term weight gain and metabolic dysfunction. Any initial weight loss is quickly and overwhelmingly reversed.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">The Psychological Toll: Appetite, Cravings, and Decision-Making<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">We&#39;ve focused a lot on the physiological side, but we can&#39;t ignore the psychological impact. Honestly, this is just as important. Sleep deprivation obliterates your executive function\u2014the part of your brain responsible for willpower, impulse control, and sound judgment.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Have you ever noticed that after a terrible night&#39;s sleep, all you want is a donut, a pizza, or a bag of chips? It\u2019s not your imagination. Your sleep-deprived brain is a craving machine. The reward centers in your brain become hyper-sensitive to indulgent foods, while the prefrontal cortex, which should be pumping the brakes, is essentially offline.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">So you&#39;re left with:<\/p>\n<ul style=\"font-size: 18px; line-height: 1.8; margin: 1.5em 0; padding-left: 2.5em; list-style-type: disc;\">\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\"><strong style=\"font-weight: 700; color: inherit;\">Intense Cravings:<\/strong> Driven by hormonal imbalance and a brain seeking quick energy.<\/li>\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\"><strong style=\"font-weight: 700; color: inherit;\">A Larger Appetite:<\/strong> Ghrelin is running rampant.<\/li>\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\"><strong style=\"font-weight: 700; color: inherit;\">Zero Willpower:<\/strong> Your executive function has checked out.<\/li>\n<\/ul>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Even if you were trying to eat healthily, you&#39;re fighting an unwinnable war against your own neurochemistry. This psychological breakdown makes it nearly impossible to stick to any kind of nutrition plan and is another reason why poor sleep is so tightly linked to weight gain over time.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Why This &#39;Weight Loss&#39; Is a Dangerous Illusion<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Let&#39;s put this all together. The &#39;weight loss&#39; that can be caused by a lack of sleep is a perfect storm of negative effects:<\/p>\n<ul style=\"font-size: 18px; line-height: 1.8; margin: 1.5em 0; padding-left: 2.5em; list-style-type: disc;\">\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\"><strong style=\"font-weight: 700; color: inherit;\">It\u2019s primarily muscle and water, not fat.<\/strong><\/li>\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\"><strong style=\"font-weight: 700; color: inherit;\">It lowers your long-term metabolism.<\/strong><\/li>\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\"><strong style=\"font-weight: 700; color: inherit;\">It\u2019s driven by a destructive stress response.<\/strong><\/li>\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\"><strong style=\"font-weight: 700; color: inherit;\">It promotes the storage of dangerous visceral fat.<\/strong><\/li>\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\"><strong style=\"font-weight: 700; color: inherit;\">It&#39;s accompanied by intense cravings and poor food choices.<\/strong><\/li>\n<\/ul>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">It\u2019s a catastrophic process for your body. Using sleep deprivation as a weight loss tool is like trying to put out a fire with gasoline. You might create a momentary distraction, but you\u2019re making the underlying problem exponentially worse.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">A Smarter Path to Sustainable Weight Management<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">So, what&#39;s the right approach? It\u2019s about working <em style=\"font-style: italic; color: inherit;\">with<\/em> your body&#39;s biology, not against it. Our entire philosophy at TrimrX is built on this principle. Sustainable weight management isn&#39;t about quick fixes or punishing your body into submission. It\u2019s about restoring balance.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\"><strong style=\"font-weight: 700; color: inherit;\">1. Prioritize Sleep. No, Really.<\/strong><br \/>We can&#39;t say this enough: sleep is a non-negotiable pillar of health and weight management. Aim for 7-9 hours of quality sleep per night. This isn&#39;t a luxury; it&#39;s a biological necessity. It allows your hormones to regulate, your muscles to repair, and your brain to reset. It\u2019s the foundation upon which everything else is built.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\"><strong style=\"font-weight: 700; color: inherit;\">2. Focus on Body Composition, Not Just Weight.<\/strong><br \/>Stop obsessing over the number on the scale and start thinking about body composition\u2014your ratio of fat to muscle. The goal is to lose fat while preserving, or even building, metabolically active muscle. This requires a combination of smart nutrition, strength training, and, of course, adequate rest.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\"><strong style=\"font-weight: 700; color: inherit;\">3. Address the Hormonal Root Causes.<\/strong><br \/>For many people, despite their best efforts with diet and exercise, hormonal imbalances make weight loss feel like an impossible, uphill battle. This is where medical supervision can be a game-changer. At TrimrX, we use cutting-edge, FDA-registered GLP-1 medications like Semaglutide and Tirzepatide. These treatments work by targeting the very same hormonal pathways that sleep deprivation disrupts. They help regulate appetite, improve insulin sensitivity, and restore the biological signals that lead to healthy, sustainable fat loss.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">If you feel like you&#39;re doing everything right but still struggling, it might be time to look deeper at your biology. It&#39;s not about a lack of willpower; it&#39;s about a physiological imbalance that needs to be addressed. A great first step is to see if a medically-supervised program is right for you.

Pushing it with sleep deprivation sends it into a state of crisis. While that crisis might briefly manifest as a lower number on the scale, the long-term cost to your metabolism, your hormonal health, and your quality of life is far too high. True wellness begins with rest. It begins with respecting your body&#39;s fundamental needs and building a strategy for health that is sustainable for a lifetime.<\/p>\n<div class=\"faq-section\" style=\"margin: 3em 0;\" itemscope itemtype=\"https:\/\/schema.org\/FAQPage\">\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 1em 0; color: #000;\">Frequently Asked Questions<\/h2>\n<details class=\"faq-item\" style=\"margin-bottom: 1em; border-bottom: 1px solid #e0e0e0; padding: 1em 0;\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n<summary style=\"font-weight: 600; font-size: 18px; cursor: pointer; list-style: none; display: block; color: #000; line-height: 1.6; position: relative; padding-right: 40px;\" itemprop=\"name\">Can losing just one hour of sleep per night cause weight changes?<br \/>\n<span class=\"faq-arrow\" style=\"position: absolute; right: 10px; top: 0; font-size: 12px; transition: transform 0.3s;\">\u25bc<\/span><br \/>\n<\/summary>\n<div style=\"margin-top: 0.8em; padding-top: 0.8em;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size: 18px; line-height: 1.8; color: #333; margin: 0;\" itemprop=\"text\">Absolutely. Even a small, chronic sleep deficit can disrupt appetite-regulating hormones like ghrelin and leptin and increase cortisol.

The physiological state induced by sleep deprivation\u2014high cortisol and insulin resistance\u2014is catabolic to muscle and anabolic to fat. Your body is primed to break down muscle for quick energy while preserving and storing fat, making fat loss nearly impossible.<\/p>\n<\/div>\n<\/details>\n<details class=\"faq-item\" style=\"margin-bottom: 1em; border-bottom: 1px solid #e0e0e0; padding: 1em 0;\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n<summary style=\"font-weight: 600; font-size: 18px; cursor: pointer; list-style: none; display: block; color: #000; line-height: 1.6; position: relative; padding-right: 40px;\" itemprop=\"name\">How quickly do sleep habits affect weight?<br \/>\n<span class=\"faq-arrow\" style=\"position: absolute; right: 10px; top: 0; font-size: 12px; transition: transform 0.3s;\">\u25bc<\/span><br \/>\n<\/summary>\n<div style=\"margin-top: 0.8em; padding-top: 0.8em;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size: 18px; line-height: 1.8; color: #333; margin: 0;\" itemprop=\"text\">The hormonal changes can happen incredibly fast.
