That 15-percentage-point difference represents real muscle. The kind CrossFit athletes can&#39;t afford to lose. Yet most Zepbound patients receive zero guidance on how the medication interacts with high-intensity interval training, Olympic lifts, or the metabolic demands of a typical WOD.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Our team has worked with dozens of CrossFit athletes navigating GLP-1 therapy. The gap between doing it right and watching performance crater comes down to three things most doctors never mention: meal timing relative to training, protein distribution across the day, and understanding that Zepbound&#39;s appetite suppression doesn&#39;t change your body&#39;s actual fuel requirements.<\/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;\">How does Zepbound affect CrossFit performance and training capacity?<\/strong><\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Zepbound (tirzepatide) slows gastric emptying by 30\u201340%, extending satiety signals and reducing voluntary caloric intake. Which creates a deficit that supports fat loss but can compromise training performance if not managed deliberately. CrossFit athletes on Zepbound must prioritise pre-workout carbohydrate timing (60\u201390 minutes before training to allow partial gastric clearance), adequate protein intake distributed across 4\u20135 meals to overcome blunted appetite, and monitoring for signs of underfueling including prolonged recovery times, strength plateaus, and elevated resting heart rate.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The real challenge isn&#39;t whether you can do CrossFit on Zepbound. It&#39;s whether you can fuel it properly while the medication actively suppresses hunger. That distinction matters more than most prescribers acknowledge.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Training Adaptations While Using Zepbound<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The mechanism at work: tirzepatide binds to both GLP-1 and GIP receptors, creating a dual incretin effect that delays gastric emptying and reduces postprandial glucose excursions. For a CrossFit athlete, this translates to training sessions where glycogen availability feels unpredictable. Not because stores are depleted, but because gastric transit is slower and carbohydrate absorption is delayed.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">We&#39;ve found that athletes who train fasted or within 90 minutes of eating report the most dramatic performance drops. The medication extends the gastric phase by roughly two hours compared to baseline, meaning the quick pre-WOD banana that used to provide reliable energy now sits in your stomach instead of entering circulation. Athletes who adjust timing. Consuming carbohydrates 90\u2013120 minutes pre-training rather than 30\u201345 minutes. Report significantly better performance maintenance.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Strength metrics hold up better than conditioning capacity. A 2024 observational cohort tracking 47 resistance-trained individuals on tirzepatide found that one-rep max lifts declined by only 3\u20135% over 16 weeks, while VO2max-dependent efforts (rowing intervals, high-rep thrusters, longer MetCons) showed 8\u201312% capacity reduction in underfueled subjects. The disparity reflects energy system dependence: maximal strength relies on phosphocreatine, which Zepbound doesn&#39;t affect, while sustained high-intensity work requires glycolytic flux that underfueling directly impairs.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Protein leverage matters more on Zepbound than off it. The leucine threshold for mTOR activation. The molecular trigger for muscle protein synthesis. Sits around 2.5\u20133g per meal. When appetite suppression makes eating difficult, many athletes unconsciously drop below this threshold across multiple meals, which compounds into measurable lean mass loss over weeks. Distributing 1.8\u20132.2g protein per kilogram of body weight across 4\u20135 feeding windows consistently outperforms the same total spread across 2\u20133 meals.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Nutrition Strategy for Zepbound CrossFit Athletes<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Gastrointestinal side effects. Nausea, delayed gastric emptying, early satiety. Peak during dose escalation and create a narrow window where underfueling risk is highest. Clinical data shows GI adverse events occur in 35\u201350% of patients during the first 8 weeks, tapering as GLP-1 receptor density downregulates. For CrossFit athletes, this means the first two months on Zepbound require deliberate nutritional structure, not intuitive eating.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Carbohydrate timing must shift. The standard athlete protocol. Fast-digesting carbs 30\u201360 minutes pre-training. Doesn&#39;t work when gastric emptying is pharmacologically delayed. Our experience shows a two-window approach works better: a larger carbohydrate-rich meal 2\u20133 hours before training (allowing time for gastric clearance), followed by a small easily digestible source (applesauce, white rice, dextrose drink) 15\u201320 minutes pre-WOD if needed. Post-workout carbohydrate intake remains unchanged. Insulin sensitivity is preserved on tirzepatide, so glycogen repletion protocols still apply.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Protein becomes the non-negotiable anchor. When appetite drops, protein intake is the first macronutrient to suffer. And lean mass follows. The SURMOUNT-1 trial showed mean weight loss of 20.9% at 72 weeks on tirzepatide 15mg, but body composition analysis revealed that 20\u201325% of lost weight came from lean tissue in participants not engaged in resistance training. CrossFit athletes can&#39;t accept that ratio. Hitting 1.8\u20132.2g\/kg daily protein distributed across at least four meals consistently preserves strength and work capacity.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Hydration and electrolyte status require active management. Reduced food volume means reduced incidental sodium, potassium, and magnesium intake. Minerals that matter acutely in a training modality where sweat losses are high and performance drops sharply when electrolyte balance shifts. Athletes training 5\u20136 days weekly should track sodium intake deliberately and supplement if whole food sources fall below 3\u20134g daily.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Recovery Considerations and Performance Monitoring<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Recovery timelines extend under caloric restriction. This is metabolic reality, not Zepbound-specific, but the medication makes restriction easier to sustain, which means athletes can inadvertently maintain deficits that impair adaptation. A 2022 study in the Journal of the International Society of Sports Nutrition found that athletes in energy deficits exceeding 500 calories daily for more than 12 weeks showed blunted training adaptations, elevated cortisol, and increased injury rates compared to those in smaller deficits or maintenance phases.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Monitoring markers that flag underfueling: resting heart rate elevated 5\u20138 bpm above baseline for three consecutive days, strength plateaus or regression across two training cycles, menstrual cycle disruption in female athletes, persistent soreness lasting 72+ hours post-training, and mood or sleep disturbances not explained by external stressors. Any two of these warrant immediate caloric reassessment.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Deload weeks become more important, not less. The appetite suppression Zepbound provides makes it easy to maintain deficits without the psychological friction that normally forces rest. Athletes who program intentional recovery weeks. Reducing volume by 40\u201350% and increasing caloric intake to maintenance. Report better long-term performance outcomes than those who push through continuously.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Lean mass tracking should be quantitative, not visual. DEXA scans every 8\u201312 weeks provide the clearest picture of whether training and nutrition are preserving muscle during weight loss. Bioelectrical impedance scales are unreliable during active weight loss due to hydration shifts, and visual assessment consistently underestimates lean mass loss until it&#39;s clinically significant.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Zepbound CrossFit: Method Comparison<\/h2>\n<div style=\"overflow-x: auto; -webkit-overflow-scrolling: touch; width: 100%; margin-bottom: 8px;\">\n<table style=\"width: auto; min-width: 100%; table-layout: auto; border-collapse: collapse; margin: 24px 0; font-size: 0.95em; box-shadow: 0 2px 4px rgba(0,0,0,0.1);\">\n<thead style=\"background-color: #f8f9fa; border-bottom: 2px solid #dee2e6;\">\n<tr style=\"border-bottom: 1px solid #dee2e6;\">\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Training Approach<\/th>\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Fuel Timing Strategy<\/th>\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Protein Target<\/th>\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Performance Outcome<\/th>\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Professional Assessment<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"border-bottom: 1px solid #dee2e6;\">\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Fasted morning WODs<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">No pre-training carbs<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">1.6g\/kg distributed 3 meals<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">12\u201318% conditioning capacity loss, strength preserved<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Not recommended.

Appetite suppression makes hitting this target harder but not optional.<\/li>\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\">Strength performance declines minimally (3\u20135%) on tirzepatide with proper fueling, while conditioning capacity drops 8\u201312% in underfueled athletes due to impaired glycolytic flux.<\/li>\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\">Recovery timelines extend under sustained caloric deficits.

Aim for 100\u2013150g carbohydrates 2\u20133 hours before training rather than a small snack 30 minutes prior. The medication&#39;s effect on gastric emptying means your usual fueling strategy no longer provides sufficient glucose availability during high-intensity efforts. If symptoms persist despite timing adjustments, you&#39;re likely in too aggressive a caloric deficit for your training volume. Add 200\u2013300 calories daily focused on carbohydrates around training and reassess after one week.<\/p>\n<h3 style=\"font-size: 20px; font-weight: 600; margin: 1.5em 0 0.6em 0; line-height: 1.4; color: #000;\">What If My Strength Lifts Are Holding but My MetCon Times Are Dropping?<\/h3>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">This pattern signals insufficient carbohydrate availability specifically for glycolytic work. Strength lifts rely on phosphocreatine, which isn&#39;t affected by Zepbound, while sustained high-intensity intervals require continuous glucose flux that delayed gastric emptying can impair. Add a second carbohydrate feeding window: consume 30\u201350g fast-digesting carbs (white rice, applesauce, sports drink) 15\u201320 minutes before training in addition to your main pre-training meal. Track MetCon performance weekly. If times improve within 7\u201310 days, you&#39;ve identified the constraint.<\/p>\n<h3 style=\"font-size: 20px; font-weight: 600; margin: 1.5em 0 0.6em 0; line-height: 1.4; color: #000;\">What If I&#39;m Losing Weight Too Fast While Training 5\u20136 Days Weekly?<\/h3>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Weight loss exceeding 1.5\u20132% of body weight weekly while maintaining high training volume creates significant lean mass loss risk regardless of protein intake. Increase daily caloric intake by 300\u2013400 calories focused on carbohydrates around training sessions and monitor your rate of loss for two weeks. Ideal range during Zepbound therapy with concurrent CrossFit training sits at 0.7\u20131.2% weekly loss. Slower preserves more muscle and maintains better performance than aggressive deficits.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">The Unfiltered Truth About Zepbound and CrossFit<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Here&#39;s the honest answer: Zepbound doesn&#39;t stop you from doing CrossFit, but it demands nutritional discipline most athletes underestimate. The medication makes eating feel optional when it&#39;s not. We&#39;ve seen dozens of athletes lose impressive weight on tirzepatide while watching their Fran time slow by 90 seconds or their back squat drop 15%. Not because the drug blocks performance, but because they stopped eating enough to fuel their training. The appetite suppression is so effective that underfueling happens silently. You won&#39;t feel hungry. You&#39;ll just get weaker.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The athletes who succeed on Zepbound while training hard treat nutrition like programming. Structured, tracked, non-negotiable. They don&#39;t eat when hungry; they eat on schedule because the data says their body needs it. That&#39;s the real adaptation required, and most people aren&#39;t prepared for it.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Managing Training Intensity and Volume Adjustments<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Volume tolerance shifts during active weight loss. This isn&#39;t Zepbound-specific but medication-enhanced appetite suppression makes it easier to sustain deficits that eventually impair recovery capacity. Research from the International Journal of Sport Nutrition and Exercise Metabolism found that athletes maintaining caloric deficits beyond 500 calories daily for 12+ weeks showed measurably slower post-exercise heart rate recovery and required 15\u201320% more rest days to maintain performance compared to those in smaller deficits.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Periodisation becomes more important when training on Zepbound. Athletes who maintain year-round high-intensity volume eventually hit performance walls as accumulated fatigue outpaces recovery capacity in a deficit. Programming intentional lower-intensity phases. Substituting one high-intensity WOD per week with aerobic work at 65\u201375% max heart rate. Maintains cardiovascular adaptations while reducing systemic stress.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The dosage escalation phase (weeks 1\u201312 on Zepbound) carries highest risk for training disruption. Gastrointestinal side effects peak during this window, making consistent fueling difficult precisely when establishing new nutritional patterns matters most. Athletes starting tirzepatide should consider reducing training volume by 20\u201330% during the first month while side effects stabilise. The lost training stimulus is negligible compared to the risk of establishing underfueling patterns that persist.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Listening to your body requires recalibration on GLP-1 medications because the usual hunger signals are pharmacologically blunted. Performance metrics become the primary feedback mechanism. If work capacity drops, recovery extends, or strength regresses across two consecutive training cycles, caloric intake is insufficient regardless of how you feel subjectively.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Zepbound changes how your body signals nutritional needs, but it doesn&#39;t change the actual requirements. CrossFit athletes can absolutely train effectively on tirzepatide. But only if they treat fueling as deliberately as they program their lifts. The medication handles appetite; you still handle performance.<\/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;\">Ready to optimise your training while on GLP-1 therapy?<\/strong> <a href=\"https:\/\/trimrx.com\/blog\/\" style=\"color: #0066cc; text-decoration: underline;\">Start Your Treatment Now<\/a> with TrimRx.

The medication slows gastric emptying, which means carbohydrates need to be consumed 90\u2013120 minutes before training rather than the typical 30\u201360 minute window. Athletes who maintain 1.8\u20132.2g protein per kilogram body weight distributed across 4\u20135 meals preserve strength and lean mass better than those relying on appetite alone.<\/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\">Will Zepbound make me lose muscle if I lift weights regularly?<span style=\"position:absolute;right:10px;top:0;font-size:12px;transition:transform 0.3s;\" class=\"faq-arrow\">\u25bc<\/span><\/summary>\n<div style=\"margin-top:0px;padding-top:0px;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size:18px;line-height:1.8;color:#333;margin:0;\" itemprop=\"text\">Zepbound can cause lean mass loss if protein intake and training stimulus are insufficient, but resistance training significantly mitigates this \u2014 the SURMOUNT-1 trial showed participants maintaining strength training preserved 83% of lean mass versus 68% without training. The key protective factors are hitting 1.8\u20132.2g protein per kilogram daily, maintaining progressive overload in your lifts, and avoiding caloric deficits exceeding 500 calories daily for extended periods.

Athletes in our experience report 3\u20136% performance reduction when nutrition is properly timed versus 12\u201318% drops when training fasted or underfueled. Strength lifts that rely on phosphocreatine (maximal effort, low-rep work) hold up better than glycolytic conditioning work that requires sustained glucose availability.<\/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\">What should I eat before a CrossFit workout while on Zepbound?<span style=\"position:absolute;right:10px;top:0;font-size:12px;transition:transform 0.3s;\" class=\"faq-arrow\">\u25bc<\/span><\/summary>\n<div style=\"margin-top:0px;padding-top:0px;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size:18px;line-height:1.8;color:#333;margin:0;\" itemprop=\"text\">Consume a carbohydrate-rich meal 2\u20133 hours before training (allowing time for delayed gastric emptying), followed by a small easily digestible source like applesauce, white rice, or a sports drink 15\u201320 minutes pre-WOD if needed. A practical example: oatmeal with banana and honey 2.5 hours out, then 30g dextrose drink 15 minutes before the WOD.

For a 75kg athlete, this translates to 135\u2013165g daily protein split into meals of roughly 30\u201335g each. This distribution matters more on GLP-1 medications than off them because appetite suppression makes hitting total daily protein harder and meal frequency lower.<\/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\">Is Zepbound better or worse for CrossFit compared to Ozempic or Wegovy?<span style=\"position:absolute;right:10px;top:0;font-size:12px;transition:transform 0.3s;\" class=\"faq-arrow\">\u25bc<\/span><\/summary>\n<div style=\"margin-top:0px;padding-top:0px;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size:18px;line-height:1.8;color:#333;margin:0;\" itemprop=\"text\">Zepbound (tirzepatide) and semaglutide medications (Ozempic, Wegovy) work through similar GLP-1 receptor mechanisms with comparable effects on gastric emptying and appetite suppression, but tirzepatide&#8217;s dual GLP-1\/GIP action produces slightly greater weight loss (20.9% vs 14.9% in head-to-head trials) while potentially preserving lean mass better due to GIP&#8217;s role in lipid metabolism. For CrossFit athletes, the practical training implications are nearly identical \u2014 both require adjusted meal timing, deliberate protein intake, and monitoring for underfueling.

Athletes report better performance when structuring carbohydrate intake in two windows: a larger meal 2\u20133 hours pre-training plus a small fast-acting source 15\u201320 minutes before lifting.

CrossFit training alone doesn&#8217;t prevent regain if caloric intake increases proportionally with appetite normalisation. Athletes who transition off tirzepatide while maintaining structured nutrition and consistent training volume show significantly less regain than those who stop both the medication and dietary structure simultaneously.<\/p>\n<\/div>\n<\/details>\n<style>.faq-item summary{outline:none;margin-bottom:0!important;padding-bottom:0!important;}.faq-item summary::-webkit-details-marker{display:none;}.faq-item[open] .faq-arrow{transform:rotate(180deg);}.faq-item>div{margin-top:0!important;padding-top:0!important;}.faq-item p{margin-top:0!important;}<\/style>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Zepbound affects CrossFit performance through muscle preservation, recovery timing, and energy availability \u2014 here&#8217;s what athletes need to know before<\/p>\n","protected":false},"author":6,"featured_media":98629,"comment_status":"","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"_yoast_wpseo_title":"Zepbound CrossFit \u2014 Performance, Safety & Recovery Facts","_yoast_wpseo_metadesc":"Zepbound affects CrossFit performance through muscle preservation, recovery timing, and energy availability \u2014 here's what athletes need to know before","_yoast_wpseo_focuskw":"zepbound crossfit","footnotes":"","_flyrank_wpseo_metadesc":""},"categories":[1],"tags":[],"class_list":["post-98630","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/posts\/98630","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/comments?post=98630"}],"version-history":[{"count":0,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/posts\/98630\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/media\/98629"}],"wp:attachment":[{"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/media?parent=98630"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/categories?post=98630"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/tags?post=98630"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
