Despite this collective effort, the biological reality of weight management remains one of the most misunderstood topics in modern health. Most people are familiar with the fundamental principle of 'calories in versus calories out,' yet many find that the math doesn't always translate into real-world results as smoothly as a spreadsheet suggests. The challenge lies not just in the numbers, but in the complex interplay of metabolism, hormonal signaling, and lifestyle factors that dictate how our bodies store and burn energy.\\n\\nWe recognize that the journey to a healthier weight is deeply personal and often fraught with conflicting information. At TrimRx, our journey began with a shared vision to help individuals embrace healthier lifestyles by merging cutting-edge telehealth innovations with effective weight loss solutions. We understand that sustainable results require more than just a deficit; they require a supportive, science-based framework that respects your unique biology. Our platform is a user-friendly and supportive space where individuals receive personalized, medically supervised care\u2014all designed to make sustainable weight loss attainable and tailored to the individual.\\n\\nThe purpose of this blog post is to provide a comprehensive analysis of the caloric mathematics required for weight loss. We will explore how to calculate your individual needs, the science behind the '3,500-calorie rule,' and the practical strategies you can use to reduce intake without sacrificing your well-being. By the end of this guide, you will understand exactly how many calories to cut a week to lose weight, how to adjust those numbers based on your progress, and how personalized interventions can bridge the gap when traditional methods feel out of reach.\\n\\nWe will cover the essential equations for determining your metabolic rate, the physiological changes that occur during a calorie deficit, and the importance of nutritional quality. We will also discuss how our personalized programs\u2014which may include medications like Compounded Semaglutide, Zepbound\u00ae, or Wegovy\u00ae\u2014can support your efforts. To see if you are a candidate for these personalized interventions, we encourage you to take our free assessment quiz to determine your eligibility.\\n\\nTogether, we\u2019ll explore the nuances of caloric restriction and metabolic health, providing you with the tools to build a sustainable and successful weight loss plan.\\n\\nThe Science of the Calorie Deficit\\n\\nTo understand how many calories to cut a week to lose weight, we must first define what a calorie actually is. In the context of nutrition, a calorie is a unit of energy. Specifically, it is the amount of energy required to raise the temperature of one gram of water by one degree Celsius. Our bodies require this energy to maintain basic life-sustaining functions\u2014such as breathing, circulating blood, and cellular repair\u2014as well as to power physical movement.\\n\\nBasal Metabolic Rate and Total Daily Energy Expenditure\\n\\nThe foundation of any weight loss plan is an understanding of how much energy your body uses in a typical 24-hour period. This is divided into two primary categories:\\n\\nBasal Metabolic Rate (BMR): This represents the number of calories your body burns at rest to maintain vital functions. Even if you were to remain stationary in bed all day, your brain, heart, lungs, and kidneys would still require a significant amount of energy to operate.\\nTotal Daily Energy Expenditure (TDEE): This is the total number of calories you burn after accounting for all physical activity, including structured exercise and non-exercise activity thermogenesis (NEAT), such as walking to your car or folding laundry.\\n\\nAt TrimRx, we believe that sustainable weight loss should be achieved through science, empathy, and a transparent approach. Understanding these numbers is the first step toward that transparency. If you consume more calories than your TDEE, the excess energy is stored, primarily as adipose tissue (fat). If you consume fewer than your TDEE, your body must tap into those stored energy reserves to make up the difference, resulting in weight loss.\\n\\nThe Mifflin-St Jeor Equation\\n\\nWhile there are several formulas used to estimate BMR, the Mifflin-St Jeor Equation is currently considered the most accurate for the general population. It takes into account your weight, height, age, and biological sex.\\n\\nFor Men: BMR = (10 \u00d7 weight in kg) + (6.25 \u00d7 height in cm) - (5 \u00d7 age in years) + 5\\nFor Women: BMR = (10 \u00d7 weight in kg) + (6.25 \u00d7 height in cm) - (5 \u00d7 age in years) - 161\\n\\nOnce the BMR is established, it is multiplied by an activity factor\u2014ranging from 1.2 for sedentary individuals to 1.9 for those with extremely active jobs or training schedules\u2014to determine the TDEE. This number serves as your 'maintenance' level. Any reduction from this number constitutes a calorie deficit.\\n\\nCalculating the Weekly Deficit: The 3,500-Calorie Rule\\n\\nFor decades, the gold standard for weight loss has been the '3,500-calorie rule.' This rule is based on the observation that one pound of body fat contains approximately 3,500 calories of stored energy. Therefore, to lose one pound of fat per week, an individual would theoretically need to create a total weekly deficit of 3,500 calories.\\n\\nBreaking Down the Daily Reduction\\n\\nWhen distributed across seven days, a 3,500-calorie weekly deficit translates to a 500-calorie daily reduction. For most individuals struggling with overweight or obesity, cutting 500 calories a day is a manageable starting point that allows for gradual, steady progress.\\n\\nIf an individual\u2019s TDEE is 2,500 calories, consuming 2,000 calories per day should, in theory, result in the loss of one pound per week. If the goal is to lose two pounds per week\u2014which is generally considered the maximum safe rate of weight loss without medical supervision\u2014the deficit would need to increase to 1,000 calories per day.\\n\\nWhy the Math Isn't Always Perfect\\n\\nWhile the 3,500-calorie rule is a helpful guideline, modern research suggests it may be an oversimplification. The human body is not a static machine; it is a dynamic biological system that adapts to changes in energy intake. When you reduce your calories, several things happen:\\n\\nMetabolic Adaptation: As you lose weight, your body requires less energy to move and maintain itself. Your BMR naturally drops because there is less mass to support.\\nBody Composition Changes: Weight loss is rarely 100% fat. It typically involves a combination of fat, lean muscle tissue, and water. Because muscle is more metabolically active than fat, losing muscle can further decrease your BMR.\\nThe Thermic Effect of Food (TEF): Digestion itself burns calories. When you eat less food, you also burn fewer calories through the process of digestion.\\n\\nBecause of these factors, a 500-calorie daily deficit might result in a full pound of loss in the first few weeks, but that rate may slow down as the body adapts. This is where personalized care becomes essential. To navigate these biological shifts, many people find success by combining dietary changes with medically supervised programs. You can start your journey with our personalized treatment plan quiz to see which of our prescription options, such as Compounded Tirzepatide or Mounjaro\u00ae, might be right for you.\\n\\nFactors That Influence Your Specific Needs\\n\\nDetermining how many calories to cut a week to lose weight is not a one-size-fits-all calculation. Several biological and lifestyle factors will influence your 'sweet spot' for a deficit.\\n\\nBiological Sex and Muscle Mass\\n\\nBiological men generally have a higher percentage of lean muscle mass and larger bone structures than biological women. Because muscle tissue requires more energy to maintain than fat tissue, men often have higher BMRs and can sustain larger caloric deficits without feeling the effects of energy deprivation. Women, particularly those approaching or experiencing menopause, may face hormonal shifts that influence fat distribution and metabolic rate, necessitating a more tailored approach to caloric reduction.\\n\\nAge and Sarcopenia\\n\\nAs we age, our caloric needs naturally decrease. This is partly due to a decrease in physical activity, but it is also driven by sarcopenia\u2014the natural loss of muscle mass that occurs with aging. A 60-year-old individual will typically require fewer calories to maintain their weight than a 30-year-old of the same height and weight. For older adults, it is crucial to ensure that while calories are cut, protein intake remains high to preserve as much muscle mass as possible.\\n\\nActivity Level and NEAT\\n\\nWhile 'exercise' (like going for a run) is important, Non-Exercise Activity Thermogenesis (NEAT) often plays a larger role in total energy expenditure. For someone with a sedentary office job, the majority of their calorie burn comes from their BMR. Conversely, someone with a physically demanding job\u2014like construction or nursing\u2014burns significantly more calories throughout the day regardless of whether they 'work out.' When calculating how many calories to cut, it is vital to be honest about your true activity level to avoid setting a caloric goal that is unsustainably low.\\n\\nSustainable Strategies for Cutting Calories\\n\\nCutting calories does not have to mean living in a state of constant hunger. The most successful weight loss plans focus on high-volume, nutrient-dense foods that promote satiety while keeping energy intake low.\\n\\nPrioritize Protein and Fiber\\n\\nProtein has a higher thermic effect than fats or carbohydrates, meaning your body burns more calories processing it. More importantly, protein and fiber are the two most satiating nutrients. By increasing the intake of lean proteins (like chicken breast, fish, or tofu) and high-fiber vegetables (like broccoli, spinach, and carrots), you can feel full on fewer calories.\\n\\nDuring the transition to a calorie-restricted diet, some individuals find that their bodies need extra support to maintain nutritional balance and energy levels. Our GLP-1 Daily Support supplement is specifically formulated to help bridge these nutritional gaps and support overall wellness during your weight loss journey.\\n\\nManage Liquid Calories\\n\\nOne of the simplest ways to cut 500 calories a day is to evaluate what you drink. A single 16-ounce flavored latte can contain 250 to 400 calories. A couple of sodas or glasses of juice can easily push an individual over their caloric goal without providing any feeling of fullness. Swapping these for water, sparkling water, or black coffee can create a significant portion of your weekly deficit with very little effort.\\n\\nSmart Substitutions\\n\\nSmall changes in food preparation can lead to massive caloric savings over the course of a week. Consider these factual substitutions:\\n\\nUsing Greek yogurt instead of sour cream saves approximately 235 calories per cup.\\nChoosing air-popped popcorn instead of flavored tortilla chips can save nearly 400 calories per snack.\\nOpting for grilled or broiled proteins instead of fried versions can save hundreds of calories by eliminating unnecessary fats.\\n\\nIf you are looking for an additional edge in your metabolic health, you might consider our Weight Loss Boost supplement, which is designed to support your body's natural processes as you work toward your goals.\\n\\nThe Role of Personalized Medical Solutions\\n\\nFor many, the 'eat less, move more' mantra is complicated by underlying biological factors, such as insulin resistance or hormonal imbalances, that make traditional calorie cutting difficult to sustain. At TrimRx, we combine advanced medical science with modern technology to offer a more nuanced approach.\\n\\nUnderstanding GLP-1 and GIP Medications\\n\\nModern weight loss medications, such as Semaglutide and Tirzepatide, work by mimicking natural hormones in the body that regulate appetite and blood sugar. These medications can make it significantly easier to adhere to a calorie deficit by reducing 'food noise'\u2014the intrusive, constant thoughts about eating\u2014and increasing feelings of fullness after smaller meals.\\n\\nOur offerings include:\\n\\nCompounded Semaglutide and Tirzepatide: Provided through FDA-registered and inspected pharmacies, these compounded options allow for personalized dosing.\\nBranded Medications: We offer access to FDA-approved brands like Ozempic\u00ae, Wegovy\u00ae, Mounjaro\u00ae, and Zepbound\u00ae when appropriate for the patient's clinical profile.\\n\\nThese medications are not 'magic pills,' but rather powerful tools that, when used as part of a comprehensive program, can help individuals achieve the caloric deficit necessary for significant weight loss. To see which of these options fits your health profile, we invite you to complete our free assessment quiz.\\n\\nOur Commitment to Safety and Support\\n\\nWe believe that medical weight loss should be transparent and supportive. Our program includes doctor consultations, required lab work, and unlimited support\u2014all with no hidden fees. We partner exclusively with FDA-registered and inspected pharmacies for the shipping of all weight loss medications to ensure the highest standards of safety. It is our goal to make sustainable weight loss attainable through a blend of empathy and rigorous science.\\n\\nPotential Pitfalls to Avoid\\n\\nWhile creating a deficit is necessary, cutting too many calories can be just as counterproductive as eating too many.\\n\\nThe Dangers of 'Starvation Mode'\\n\\nIf you reduce your calories too drastically\u2014generally defined as going below 1,200 calories per day for women or 1,500 for men without medical supervision\u2014your body may enter a state of extreme metabolic adaptation. In this state, your body becomes highly efficient at conserving energy, which can cause weight loss to stall. Furthermore, extreme restriction often leads to 'rebound' weight gain, where the weight is quickly regained, often as fat, once the individual returns to a normal eating pattern.\\n\\nIgnoring Nutritional Quality\\n\\nA 'calorie is a calorie' for weight loss, but a 'calorie is not a calorie' for health and satiety. While it is technically possible to lose weight eating only processed snacks, the lack of protein, vitamins, and minerals will eventually lead to muscle loss, fatigue, and poor health outcomes. Our approach emphasizes that while we are focused on the deficit, we are equally focused on the quality of the fuel you provide your body.\\n\\nInconsistent Tracking\\n\\nWeight loss is often a game of averages. An individual might maintain a perfect 500-calorie deficit from Monday through Friday, but then consume an extra 2,500 calories over the weekend through alcohol and large restaurant meals. This effectively erases the weekly deficit. Consistency\u2014not perfection\u2014is the key to seeing results on the scale.\\n\\nTracking Progress and Making Adjustments\\n\\nOnce you have determined how many calories to cut a week to lose weight, it is essential to monitor your progress and be prepared to pivot.\\n\\nBeyond the Scale\\n\\nWeight fluctuates daily due to water retention, salt intake, and hormonal cycles. We recommend weighing yourself under consistent conditions (such as first thing in the morning) and looking at weekly averages rather than daily numbers. Additionally, taking body measurements and tracking how your clothes fit can provide a more accurate picture of fat loss, especially if you are also engaging in strength training.\\n\\nWhen to Adjust the Deficit\\n\\nAs you lose weight, your TDEE will decrease. If your weight loss plateaus for more than three or four weeks, it may be time to recalculate your BMR and TDEE based on your new, lower weight. This might involve cutting an additional 100-200 calories or increasing your physical activity to re-establish a deficit.\\n\\nIf you find that your progress has stalled despite your best efforts, it may be time for a more personalized intervention. Our medically supervised programs are designed to help you break through plateaus by addressing the biological barriers to weight loss. You can take the first step by completing our eligibility quiz.\\n\\nConclusion\\n\\nDetermining how many calories to cut a week to lose weight is a fundamental step toward achieving your health goals, but it is only one piece of a much larger puzzle. While the traditional 500-calorie-per-day reduction provides a solid framework for losing approximately one pound per week, the reality of human biology requires a more flexible and personalized approach. By understanding your BMR, accounting for your activity levels, and prioritizing high-quality, nutrient-dense foods, you can create a sustainable path to success.\\n\\nAt TrimRx, we are dedicated to providing the tools and support you need to navigate this journey safely and effectively. Whether you are looking for nutritional support through our GLP-1 Daily Support or require a more robust, medically supervised program involving prescription medications, we are here to partner with you.\\n\\nSustainable weight loss is not about deprivation; it is about empowerment through knowledge and personalized care. We invite you to explore our resources, utilize our supplements, and join a community that values your unique journey toward a healthier, more vibrant life.\\n\\nFrequently Asked Questions (FAQs)\\n\\n1. Is it safe to lose more than two pounds per week?\\n\\nIn most cases, losing more than two pounds per week is not recommended unless you are under strict medical supervision. Rapid weight loss often results in the loss of muscle mass and can lead to gallstones, nutritional deficiencies, and a significant drop in metabolic rate. A slower, steadier pace of one to two pounds per week is much more likely to be sustainable in the long term.\\n\\n2. Do I have to count every single calorie to lose weight?\\n\\nWhile meticulous calorie counting is an effective tool for many, it is not the only way to lose weight. Some people prefer focusing on portion control, 'plate methods' (where half the plate is vegetables), or restricting certain high-calorie food groups. However, if you are not seeing progress, tracking your calories for a week or two can provide valuable insight into where hidden calories may be sneaking into your diet.\\n\\n3. What should I do if I am always hungry on a calorie deficit?\\n\\nChronic hunger is often a sign that your diet lacks enough protein, fiber, or volume. Try increasing your intake of leafy greens and lean proteins. Additionally, some people find that their hunger is driven by hormonal signals that make traditional dieting extremely difficult. In these cases, a personalized medical weight loss plan can help regulate these signals and make a deficit much more comfortable.\\n\\n4. How do I know if my metabolism has 'broken' from dieting?\\n\\nMetabolism doesn't usually 'break,' but it does adapt. If you have been in a deficit for a long time and weight loss has stopped, your body may have become very efficient at living on fewer calories. Taking a 'diet break' where you eat at your maintenance calories for a week or two can sometimes help reset your hormonal signals and make future weight loss efforts more effective. Additionally, adding resistance training can help boost your metabolism by building muscle.\",\n  \"author\": {\n    \"@type\": \"Person\",\n    \"name\": \"TrimRX\"\n  },\n  \"publisher\": {\n    \"@type\": \"Organization\",\n    \"name\": \"TrimRX\"\n  },\n  \"datePublished\": \"2026-02-06T12:41:51.247Z\",\n  \"dateModified\": \"2026-02-06T12:41:51.247Z\"\n}<\/script><\/head><body>\n<h2 id=\"section1\"><span data-mce-fragment=\"1\">Introduction<\/span><\/h2>\n<p>In a single year, approximately half of the adult population in the United States attempts to lose weight.

Swapping these for water, sparkling water, or black coffee can create a significant portion of your weekly deficit with very little effort.<\/p>\n<h3>Smart Substitutions<\/h3>\n<p>Small changes in food preparation can lead to massive caloric savings over the course of a week. Consider these factual substitutions:<\/p>\n<ul>\n<li>Using Greek yogurt instead of sour cream saves approximately 235 calories per cup.<\/li>\n<li>Choosing air-popped popcorn instead of flavored tortilla chips can save nearly 400 calories per snack.<\/li>\n<li>Opting for grilled or broiled proteins instead of fried versions can save hundreds of calories by eliminating unnecessary fats.<\/li>\n<\/ul>\n<p>If you are looking for an additional edge in your metabolic health, you might consider our <a href=\"https:\/\/trimrx.com\/lp-wlboost\/?utm_source=flyrank&amp;utm_medium=referral&amp;utm_campaign=blog&amp;utm_source_platform=flyrank\">Weight Loss Boost supplement<\/a>, which is designed to support your body&#8217;s natural processes as you work toward your goals.<\/p>\n<h2 id=\"section6\"><span data-mce-fragment=\"1\">The Role of Personalized Medical Solutions<\/span><\/h2>\n<p>For many, the &#8220;eat less, move more&#8221; mantra is complicated by underlying biological factors, such as insulin resistance or hormonal imbalances, that make traditional calorie cutting difficult to sustain. At TrimRx, we combine advanced medical science with modern technology to offer a more nuanced approach.<\/p>\n<h3>Understanding GLP-1 and GIP Medications<\/h3>\n<p>Modern weight loss medications, such as Semaglutide and Tirzepatide, work by mimicking natural hormones in the body that regulate appetite and blood sugar. These medications can make it significantly easier to adhere to a calorie deficit by reducing &#8220;food noise&#8221;\u2014the intrusive, constant thoughts about eating\u2014and increasing feelings of fullness after smaller meals.<\/p>\n<p>Our offerings include:<\/p>\n<ul>\n<li><strong>Compounded Semaglutide and Tirzepatide:<\/strong> Provided through FDA-registered and inspected pharmacies, these compounded options allow for personalized dosing.<\/li>\n<li><strong>Branded Medications:<\/strong> We offer access to FDA-approved brands like Ozempic\u00ae, Wegovy\u00ae, Mounjaro\u00ae, and Zepbound\u00ae when appropriate for the patient&#8217;s clinical profile.<\/li>\n<\/ul>\n<p>These medications are not &#8220;magic pills,&#8221; but rather powerful tools that, when used as part of a comprehensive program, can help individuals achieve the caloric deficit necessary for significant weight loss. To see which of these options fits your health profile, we invite you to <a href=\"https:\/\/start.trimrx.com\/intake\/trimrx\/glp1\/height_weight?utm_source=flyrank&amp;utm_medium=referral&amp;utm_campaign=blog&amp;utm_source_platform=flyrank\">complete our free assessment quiz<\/a>.<\/p>\n<h3>Our Commitment to Safety and Support<\/h3>\n<p>We believe that medical weight loss should be transparent and supportive. Our program includes doctor consultations, required lab work, and unlimited support\u2014all with no hidden fees. We partner exclusively with FDA-registered and inspected pharmacies for the shipping of all weight loss medications to ensure the highest standards of safety. It is our goal to make sustainable weight loss attainable through a blend of empathy and rigorous science.<\/p>\n<h2 id=\"section7\"><span data-mce-fragment=\"1\">Potential Pitfalls to Avoid<\/span><\/h2>\n<p>While creating a deficit is necessary, cutting too many calories can be just as counterproductive as eating too many.<\/p>\n<h3>The Dangers of &#8220;Starvation Mode&#8221;<\/h3>\n<p>If you reduce your calories too drastically\u2014generally defined as going below 1,200 calories per day for women or 1,500 for men without medical supervision\u2014your body may enter a state of extreme metabolic adaptation. In this state, your body becomes highly efficient at conserving energy, which can cause weight loss to stall. Furthermore, extreme restriction often leads to &#8220;rebound&#8221; weight gain, where the weight is quickly regained, often as fat, once the individual returns to a normal eating pattern.<\/p>\n<h3>Ignoring Nutritional Quality<\/h3>\n<p>A &#8220;calorie is a calorie&#8221; for weight loss, but a &#8220;calorie is not a calorie&#8221; for health and satiety. While it is technically possible to lose weight eating only processed snacks, the lack of protein, vitamins, and minerals will eventually lead to muscle loss, fatigue, and poor health outcomes. Our approach emphasizes that while we are focused on the deficit, we are equally focused on the quality of the fuel you provide your body.<\/p>\n<h3>Inconsistent Tracking<\/h3>\n<p>Weight loss is often a game of averages. An individual might maintain a perfect 500-calorie deficit from Monday through Friday, but then consume an extra 2,500 calories over the weekend through alcohol and large restaurant meals. This effectively erases the weekly deficit. Consistency\u2014not perfection\u2014is the key to seeing results on the scale.<\/p>\n<h2 id=\"section8\"><span data-mce-fragment=\"1\">Tracking Progress and Making Adjustments<\/span><\/h2>\n<p>Once you have determined how many calories to cut a week to lose weight, it is essential to monitor your progress and be prepared to pivot.<\/p>\n<h3>Beyond the Scale<\/h3>\n<p>Weight fluctuates daily due to water retention, salt intake, and hormonal cycles. We recommend weighing yourself under consistent conditions (such as first thing in the morning) and looking at weekly averages rather than daily numbers. Additionally, taking body measurements and tracking how your clothes fit can provide a more accurate picture of fat loss, especially if you are also engaging in strength training.<\/p>\n<h3>When to Adjust the Deficit<\/h3>\n<p>As you lose weight, your TDEE will decrease. If your weight loss plateaus for more than three or four weeks, it may be time to recalculate your BMR and TDEE based on your new, lower weight. This might involve cutting an additional 100-200 calories or increasing your physical activity to re-establish a deficit.<\/p>\n<p>If you find that your progress has stalled despite your best efforts, it may be time for a more personalized intervention. Our medically supervised programs are designed to help you break through plateaus by addressing the biological barriers to weight loss.

While the traditional 500-calorie-per-day reduction provides a solid framework for losing approximately one pound per week, the reality of human biology requires a more flexible and personalized approach.

Is it safe to lose more than two pounds per week?<\/h3>\n<p>In most cases, losing more than two pounds per week is not recommended unless you are under strict medical supervision. Rapid weight loss often results in the loss of muscle mass and can lead to gallstones, nutritional deficiencies, and a significant drop in metabolic rate. A slower, steadier pace of one to two pounds per week is much more likely to be sustainable in the long term.<\/p>\n<h3>2. Do I have to count every single calorie to lose weight?<\/h3>\n<p>While meticulous calorie counting is an effective tool for many, it is not the only way to lose weight. Some people prefer focusing on portion control, &#8220;plate methods&#8221; (where half the plate is vegetables), or restricting certain high-calorie food groups. However, if you are not seeing progress, tracking your calories for a week or two can provide valuable insight into where hidden calories may be sneaking into your diet.<\/p>\n<h3>3. What should I do if I am always hungry on a calorie deficit?<\/h3>\n<p>Chronic hunger is often a sign that your diet lacks enough protein, fiber, or volume. Try increasing your intake of leafy greens and lean proteins. Additionally, some people find that their hunger is driven by hormonal signals that make traditional dieting extremely difficult. In these cases, a <a href=\"https:\/\/start.trimrx.com\/intake\/trimrx\/glp1\/height_weight?utm_source=flyrank&amp;utm_medium=referral&amp;utm_campaign=blog&amp;utm_source_platform=flyrank\">personalized medical weight loss plan<\/a> can help regulate these signals and make a deficit much more comfortable.<\/p>\n<h3>4. How do I know if my metabolism has &#8220;broken&#8221; from dieting?<\/h3>\n<p>Metabolism doesn&#8217;t usually &#8220;break,&#8221; but it does adapt. If you have been in a deficit for a long time and weight loss has stopped, your body may have become very efficient at living on fewer calories. Taking a &#8220;diet break&#8221; where you eat at your maintenance calories for a week or two can sometimes help reset your hormonal signals and make future weight loss efforts more effective. Additionally, adding resistance training can help boost your metabolism by building muscle.<\/p>\n<\/body><\/html>","protected":false},"excerpt":{"rendered":"<p>Wondering how many calories to cut a week to lose weight?
