Raymond Forbes LLC\/StocksyAccording to a new review, understanding your biological clock and chronotype might help you build muscle and lose weight more effectively.Working with, rather than against, your chronotype \u2014 such as being a night owl or an early bird \u2014 could increase performance and support metabolic health.The review also highlights the importance of maintaining muscle mass in promoting healthy aging.Medical experts also touch on three key areas night owls can improve their health.<\/p>\n<p>Do you wake with the larks or stay up with the owls? According to a recent review, understanding your chronotype might help you maximize your gains when training and stay healthier as you age.<\/p>\n<p>The authors hope that their findings, published in <a href=\"https:\/\/www.mdpi.com\/2072-6643\/18\/2\/221\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">Nutrients<\/a>, could help people design personalized routines to suit their biological clocks, making them more sustainable and successful.<\/p>\n<p>\u201cTaking chronotype into account can help to better tailor health recommendations and make them more sustainable over time, especially in programs for weight loss, muscle loss prevention, and the promotion of healthy aging,\u201d explained <a href=\"https:\/\/biysc.org\/biysc_persona\/nuria-vilarrasa\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">N\u00faria Vilarrasa<\/a>, MD, professor at the University of Barcelona\u2019s Faculty of Medicine and Health Sciences in Spain, in a <a href=\"https:\/\/medicalxpress.com\/news\/2026-01-night-owl-early-bird-chronotype.html\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">press release<\/a>.<\/p>\n<p>In the era of social media fitness influencers, muscles have become highly-prized fashion accessories. However, they are much more important than that. Our muscles are metabolic organs that play a wide range of functions far beyond impressing friends and colleagues.<\/p>\n<p>For instance, muscles are energy-hungry tissue, and, as such, they store glucose. This means that having a healthy level of muscle mass helps keep blood sugar levels more stable. <\/p>\n<p>Also, as we age, maintaining muscle mass becomes extra important. Older adults with significant muscle loss (sarcopenia) are more likely to experience falls and develop frailty sooner.<\/p>\n<p>Muscles also contribute to the negative health outcomes of obesity. Often, people with obesity, while gaining body fat, also lose muscle and muscle quality.<\/p>\n<p>This can create a spiral of decline: Time spent sedentary is associated with a loss of muscle and weight gain; the loss of muscle then makes physical activity more difficult.<\/p>\n<p>We all have a biological clock, known as our circadian rhythm. It helps us feel sleepy before bed and wake up feeling refreshed. Every cell in our body runs on a roughly 24-hour schedule to keep us aligned with the natural light-day cycle.<\/p>\n<p>However, how aligned individuals are with this cycle varies. Some go to bed early and wake early (larks), others go to bed late and stay awake late into the evening (night owls), and everyone else is somewhere in between.<\/p>\n<p>Our chronotype also impacts how effective training is at different times of day. Larks tend to have their best physical performance in the <a href=\"https:\/\/www.cell.com\/current-biology\/fulltext\/S0960-9822(14)01639-X\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">early afternoon<\/a>, while night owls perform best in the late afternoon or evening. <\/p>\n<p>This difference, the authors explain, helps us understand why not everyone benefits the same from exercise and nutrition routines. These differences may also contribute to muscle health.<\/p>\n<p>According to the authors of the new paper, being a night owl is \u201cconsistently associated with poorer sleep, irregular eating habits, reduced physical activity, and increased risk of obesity, sarcopenia, and metabolic disorders compared to morning types.\u201d <\/p>\n<p>They tackle night owls\u2019 potential issues with nutrition, sleep, and exercise in turn.<\/p>\n<p>Nutrition tips for a night owl<\/p>\n<p>High fat diets, the authors explain, can upset circadian rhythms. In turn, this can lead to <a href=\"https:\/\/www.medicalnewstoday.com\/articles\/305567\" target=\"_blank\" rel=\"noreferrer noopener nofollow\" class=\"content-link css-90fpmc\">insulin resistance<\/a>, inflammation, and imbalances in hormones that are important for appetite signaling, like leptin and adiponectin. <\/p>\n<p>Research also shows that meal timing is important. For instance, the authors of the review explain that the timing of the largest meal of the day is probably important. <\/p>\n<p>Night owls could benefit, they suggest, from shifting their largest meal to an earlier time in the day, rather than the evening. <\/p>\n<p>Sleep quality for night owls<\/p>\n<p>Perhaps surprisingly, sleep plays a role in muscle health. The authors explain that specific hormones, which support muscle growth and prevent muscle breakdown are partly driven by metabolic processes that are influenced by circadian rhythms.<\/p>\n<p>Lack of sleep also negatively affects muscle health by interfering with <a href=\"https:\/\/www.medicalnewstoday.com\/articles\/317536\" target=\"_blank\" rel=\"noreferrer noopener nofollow\" class=\"content-link css-90fpmc\">blood glucose (sugar)<\/a> control and, once again, disrupting hormones involved in appetite control, while boosting stress hormones such as cortisol. <\/p>\n<p>These changes reduce muscle protein synthesis, leading to muscle loss, weakness, and poorer physical function. <\/p>\n<p>The authors suggest that: \u201cTo support muscle health, adults should maintain a regular sleep-wake schedule, avoid late-night training and screen exposure, and consume protein-rich meals earlier in the evening to enhance overnight recovery.\u201d<\/p>\n<p>Exercises for an evening chronotype<\/p>\n<p>Exercise not only influences circadian rhythms, but it also plays a pivotal role in muscle growth and strength. As mentioned earlier, muscles play important metabolic roles throughout the life course.<\/p>\n<p>Exercise timing also matters, especially for night owls. Studies suggest that training in the afternoon or evening is associated with greater muscle growth, while morning training supports mitochondrial health and cellular housekeeping. <\/p>\n<p>While questions remain, the scientists also outline complex interactions between exercise and genes that help regulate the circadian clock. These relationships suggest that matching exercise timing with the body\u2019s natural rhythms might improve muscle adaptation, performance, and long-term health.<\/p>\n<p>\u201cThe main objective is for people to be active and avoid a sedentary lifestyle,\u201d <a href=\"https:\/\/scholar.google.com\/citations?user=Q2KUjYgAAAAJ&amp;hl=es\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">Pablo M. Garcia-Rov\u00e9s<\/a>, MD, a member of the MitoHealth research group, explained in the press release.<\/p>\n<p>\u201c[A] better understanding of their characteristics and habits allows for the design of more precise interventions that contribute to improving the health and functionality of the population. This approach may be particularly relevant in a society with irregular schedules and a progressively aging population.\u201d <br \/>\u2014 Pablo M. Garcia-Rov\u00e9s, MD<\/p>\n<p>Medical News Today contacted two fitness experts to ask for their advice for individuals with a late chronotype on how to get in shape and maintain health.<\/p>\n<p>\u201cIf you\u2019re an evening type, try shifting your main meals to earlier in the day to match your body\u2019s natural rhythms,\u201d suggested <a href=\"https:\/\/www.denisechakoian.com\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">Denise Chakoian<\/a>, a Rhode Island Certified Fitness Trainer and owner of Core Cycle and Fitness LaGree. Chakoian was not involved in the recent paper.<\/p>\n<p>\u201cPrioritize protein at each meal to help build and maintain muscle. Aim for consistent, good-quality sleep to support recovery and hormone balance,\u201d Chakoian added.<\/p>\n<p>She also recommended planning workouts later in the afternoon or early evening \u201cwhen your energy and strength are naturally higher.\u201d Chakoian further recommended avoiding eating just before bed, \u201cas late-night calories can increase fat storage and hurt muscle growth.\u201d<\/p>\n<p>\u2018Work with your biology\u2019<\/p>\n<p><a href=\"https:\/\/www.garagegymreviews.com\/author\/stephensheehan\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">Stephen Sheehan<\/a>, a certified personal trainer with Garage Gym Reviews who was likewise not involved in the study, suggested that night owls should \u201cwork with their biology.\u201d<\/p>\n<p>He explained that many evening types believe they have to change everything to see results: wake up before dawn and completely adjust their typical schedule.<\/p>\n<p>\u201cThat almost always backfires,\u201d he told MNT, \u201cbecause it\u2019s an all-or-nothing approach, which <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC12831378\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">studies<\/a> show can easily derail a workout program or other attempts at lifestyle change.\u201d<\/p>\n<p>Instead, Sheehan suggested night owls should \u201ccompletely ditch the idea that they need to slam weights pre-dawn, and lean into what\u2019s natural for their body.\u201d This removes the mental barrier and \u201cimproves the quality of training.\u201d<\/p>\n<p>As for food, in line with the review paper, he recommended \u201cmoving mealtimes earlier in the day, particularly one\u2019s highest-calorie meal of the day. This could positively affect health markers like fat-free mass index and body mass index (BMI), thereby positively influencing metabolic health.\u201d<\/p>\n<p>Overall, Sheehan suggested following these basic principles:<\/p>\n<p>Don\u2019t force yourself to wake up early to train.Try to train between 4 and 8 p.m.Keep a buffer of 2 hours between the end of your training session and bedtime.Eat your highest-calorie meal sometime before training, not after.Get 70% of your day\u2019s protein in before training.<\/p>\n<p>He also recommended people \u201cFind a relaxing hobby that can take the place of scrolling on your phone or watching TV before bed. Try reading, writing, knitting, coloring, building legos \u2014 whatever. Anything that isn\u2019t shining a blue light in your face. Bonus points if it\u2019s something creative (cognitive health is important, too).\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Share on PinterestA person\u2019s biological clock and chronotype, as well as their lifestyle habits, may influence their health&hellip;\n","protected":false},"author":2,"featured_media":462012,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[37],"tags":[64,63,538,137],"class_list":{"0":"post-462011","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-fitness","8":"tag-au","9":"tag-australia","10":"tag-fitness","11":"tag-health"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/462011","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=462011"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/462011\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/462012"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=462011"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=462011"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=462011"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
