In this episode, Greg and Lyndsey sit down for a discussion about cortisol with Beth Skwarecki, the senior health editor at Lifehacker. The dangers of high cortisol are a persistent topic of content on social media content, so the discussion focuses on the types of claims that are being made, the dubious methods of self-diagnosis and “treatment” being recommended, and the potential risks and dangers associated with letting social media convince you that you’re basically an endocrinologist.You can read Beth’s article on this topic here: TikTok Myth of the Week: All Your Problems Are Due to High Cortisol TIME STAMPS What is cortisol?

In the final episode of our micronutrient series, Greg and Lyndsey discuss which micronutrients are most worth monitoring and good food sources for the micronutrients you may be under-consuming. Then, we talk more broadly about why you shouldn’t allow a focus on micronutrients specifically to detract from the pursuit of a generally healthy diet.Want to get your question answered on the show?

In this episode (which is Part 2 of our micronutrient series), Greg and Lyndsey discuss nutrient targets: where they come from, what they mean, and how to think about them. They also talk about the relative imprecision of micronutrient tracking, why micronutrient content can differ so much within a single food, and why it can be challenging to track your micronutrient intake in the first place.Want to get your question answered on the show?

Micronutrients deserve more attention. There's very little content about micronutrients, and the content that *is* out there is often full of fear-mongering or wild claims about wonder drugs and super foods. In this episode, we aim to provide a solid foundation for building a better understanding of micronutrients. Along the way, Greg also shares some fun facts that prove that micronutrients are way more interesting than you may have thought. This is the first part of a micronutrient series we'll be doing on the podcast.  Want to get your question answered on the show?

The industry for pre-sleep supplements, foods, and products is booming. But what actually works, and how much does our diet actually impact our sleep quality and quantity? Greg and Lyndsey talk about how pre-sleep products are marketed, break down the science behind popular sleep supplements (like melatonin, magnesium, lavender, and more), and discuss how macronutrient distributions influence sleep. They also answer a few listener questions about pre-sleep protein and about the impact of eating meals right before bedtime. Want to get your question answered on the show?

Does creatine cause hair loss? What about bloating? In this episode, Greg and Lyndsey bust myths and misconceptions about creatine, one of the most popular supplements on the market. Greg also explains how creatine actually works to increase muscle growth and discusses myths related to creatine dosing (is 5g per day enough?). Then, they play a few listener calls about creatine and answer questions about creatine's impact on individual genetic potential for muscularity, different forms of creatine, and the interaction between caffeine and creatine.Want to get your question answered on the show?

In today’s episode, Eric responds to a few pieces of listener feedback, then covers two popular nutrition topics. In the first, he discusses the utility of calorie counting or diet tracking, and how to make the process as feasible and effective as possible. After that, he provides a thorough overview of mindful eating, while addressing some common misconceptions along the way. While many people think that mindful eating is the same thing as intuitive eating, or that mindful eating is incompatible with weight loss goals or diet tracking, neither of these popular perspectives are true. In reality, mindful eating and diet tracking can be used synergistically when pursuing a variety of goals, including weight loss. Today’s episode discusses how to use both of these evidence-based strategies in a complementary fashion. SUPPORT THE PODCASTJoin the Research Spotlight newsletter: Get a two-minute breakdown of one recent study every Wednesday.

He begins by reviewing evidence-based goal setting strategies, then discusses how we can leverage self-determination theory to get motivated to pursue our goals, and how we can lean on the COM-B (capability, opportunity, motivation, behavior) model to change behaviors in accordance with our goals. This leads to a unified, comprehensive, evidence-based model that covers goal setting, motivation, and behavior change from start to finish. SUPPORT THE PODCASTJoin the Research Spotlight newsletter: Get a two-minute breakdown of one recent study every Wednesday.

After Eric’s first earthquake experience, today’s episode begins with a brief discussion of natural disasters. That’s followed by Greg’s segment, which covers popular weight loss advice that may do more harm than good. While most of the ideas that catch on and get popular originate with bodybuilders and physique athletes, they are often misapplied when generalized to other populations (that is, most people). Finally, Eric presents a segment that addresses a very common question: what is the healthiest diet? This yields a discussion about evidence-based guidelines for structuring a diet that supports general health, wellbeing, and longevity, while addressing some common misconceptions along the way. SUPPORT THE PODCASTJoin the Research Spotlight newsletter: Get a two-minute breakdown of one recent study every Wednesday.

Today’s episode begins with a discussion about an ambitious experiment in the world of academic publishing, and the real-world costs of striving for bench press excellence. After that, Greg presents a segment about partial range-of-motion (ROM) training for strength outcomes. Greg digs into the available research about whether or not partial reps can be used to facilitate greater strength gains, and provides practical recommendations about when and how to incorporate this style of training. That’s followed by Eric’s segment that tackles a fairly widespread misconception about protein requirements for muscle growth. Many people believe that 1.6 g/kg/day is a very clear minimum requirement for supporting hypertrophy, and that falling a little bit short of this target severely limits muscle growth. However, the data suggest otherwise. He explores the available research and discusses some protein target recommendations for people who are prioritizing muscle growth or retention. SUPPORT THE PODCASTJoin the Research Spotlight newsletter: Get a two-minute breakdown of one recent study every Wednesday.

Today’s episode begins with a discussion about the very predictable scandal that rocked Fat Bear Week. After that, Greg presents a segment about accommodating resistance (that is, training with bands and chains). Greg digs into the available research and explains why accommodating resistance is beneficial for power development and explosive muscle actions, while failing to meaningfully impact maximal strength. That’s followed by Eric’s segment that clears up some misconceptions about the actual net energy cost of exercise. He explores how physical activity impacts total daily energy expenditure, describes some key characteristics that influence inter-individual differences in the net energy cost of exercise, and explains why and how to estimate the net energy cost of exercise using a new tool developed by the Stronger By Science team. SUPPORT THE PODCASTJoin the Research Spotlight newsletter: Get a two-minute breakdown of one recent study every Wednesday.

In today's episode, Greg and Eric pat themselves on the back for breaking the 100 episode barrier, in addition to sharing their picks for Fat Bear Week 2022. After that, Greg encroaches on Eric’s territory with a segment about body composition assessments. In the segment, Greg discusses what common body composition devices actually measure, how accurate (or inaccurate) they are for individuals (rather than groups), and some better strategies for monitoring progress toward fitness goals. After that, Eric steers others toward the Road to Enlightenment with a segment on the fitness-related applications of mindfulness and meditation. He specifically looks at the research evaluating mindfulness-based interventions for mental fatigue, sleep, pain management, and eating behaviors. Eric also discusses scenarios in which mindfulness-based interventions might be contraindicated, and provides some resources for people who want to give meditation or other mindfulness-based interventions a shot. SUPPORT THE PODCASTJoin the Research Spotlight newsletter: Get a two-minute breakdown of one recent study every Wednesday.

In today's episode, Eric briefly addresses some feedback and responses to his previous article and segment about reverse dieting. After that, it’s all about differences in gains between individuals. Greg begins by exploring research that describes the degree to which training-induced improvements in strength, muscularity, and aerobic fitness vary from person to person. After that, Greg leans on the available research to provide evidence-based advice about what you can actually do about it, particularly if you suspect that you’re experiencing below-average gains. SUPPORT THE PODCASTJoin the Research Spotlight newsletter: Get a two-minute breakdown of one recent study every Wednesday.

Mechanical tension, muscle damage, and metabolic stress are often viewed as the key stimuli for muscle hypertrophy. A new study asserts that mechanical activation of fast-twitch muscle fibers is the strongest determinant of muscle hypertrophy, which suggests that mechanical tension is the most noteworthy stimulus for muscle growth. This is an intuitive idea, but Greg’s segment explains why the results of this study fail to support the conclusions that were stated in the paper (and shared widely on social media). After that, Eric presents a segment that’s all about food selection. As flexible dieting and “IIFYM” continue to gain popularity, it’s indisputable that dieters can succeed using a virtually limitless variety of food sources, as long as they (approximately) hit their calorie or macro targets consistently. While it’s very true that dieters enjoy a great deal of flexibility in their food choices, this doesn’t mean that food source selection is irrelevant or inconsequential. In Eric’s segment, he discusses some evidence-based guidance for making food choices to facilitate a smoother dieting experience. SUPPORT THE PODCASTJoin the Research Spotlight newsletter: Get a two-minute breakdown of one recent study every Wednesday.

It’s very common to assume that group-level findings from research will reliably predict how you (or your clients) will respond to a particular training strategy, but that’s not always the case. In today’s episode, Greg discusses the substantial amount of inter-individual variability observed in responses to training interventions, and how to navigate training decisions in light of these hard-to-predict differences among individuals. After that, Eric discusses protein quality: what it is, what affects it, and how much it does (or doesn’t) matter from a practical perspective. His segment summarizes the research directly comparing a wide range of protein sources, and provides practical strategies for protein source selection in vegan, vegetarian, and omnivorous diets. SUPPORT THE PODCASTJoin the Research Spotlight newsletter: Get a two-minute breakdown of one recent study every Wednesday.

We’re officially back for a brand new season! In today’s episode, Greg discusses the research behind how resistance training range of motion impacts muscle growth, with a special focus on stretch-mediated hypertrophy. After that, Eric dives deep into the topic of reverse dieting, which is often touted as a remedy for metabolic adaptation and a strategy to facilitate easier and more sustainable weight loss. However, this popular approach was originally driven by industry marketing rather than scientific evidence. Eric’s segment explores the actual research related to reverse dieting, which tells a much different story than the hyped-up anecdotes you’ll see on social media. He also explains why reverse dieting often appears to work in the short term while falling flat in the long term, and why a simple maintenance phase is a better option than reverse dieting. SUPPORT THE PODCASTJoin the Research Spotlight newsletter: Get a two-minute breakdown of one recent study every Wednesday.

In today’s episode, Greg and Eric revisit the topic of buffering supplements and fatigue as Eric presents a Research Review about the mechanisms driving neuromuscular fatigue. After that, Greg discusses his cover story from the most recent issue of the MASS Research Review, which is also available at strongerbyscience.com. In the article, Greg explores under-representation of female participants within strength, hypertrophy, and supplement research. The discussion covers the extent of the disparity, the surprising observation that the gap is getting worse over time, and how this research imbalance impacts training and nutrition recommendations for female lifters. Next, Eric shares a Coach’s Corner segment about programming high-intensity interval training (HIIT) and sprint interval training (SIT) for lifters.

Today’s show is an uncharacteristically anecdote-heavy episode of the podcast. After Greg shares some new Feats of Strength, Eric presents a Coach’s Corner segment about a modified version of the “one-meal-a-day” (OMAD) eating pattern. This strategy, which may be described as protein-sparing-modified-time-restricted-eating, aims to capitalize on the potential upsides of OMAD while attenuating the downsides. After that, Greg shares his own Coach’s Corner segment about joint-friendly warm-up strategies, which leads to a broader discussion about where anecdotal evidence fits within an evidence-based approach to training, nutrition, or content creation. Next, Eric answers a listener’s question about how to retain muscle while cutting. Finally, to close out the show, Greg recommends some people you should follow on social media, along with a new media recommendation.  SUPPORT THE PODCASTReceive our Research Spotlight newsletter, and check out our Facebook group and subreddit.MacroFactorIf you want to learn more about our MacroFactor diet app, check it out  here.To join in on the MacroFactor conversation, check out our Facebook group and subreddit.MASS Research ReviewSubscribe to the MASS Research Review to get concise and applicable breakdowns of the latest strength, physique, and nutrition research – delivered monthly.Bulk SupplementsFinally, next time you stock up on supplements from BulkSupplements.com, be sure to use the promo code “SBSPOD” (all caps) to get 5% off your entire order. TIME STAMPSIntro/Announcements (0:00)Road to the Stage / Road to Athens (1:20)Feats of Strength (4:43)Coach’s Corner: protein-sparing-modified-time-restricted-feeding (modified OMAD) (6:45)Coach’s Corner: joint-friendly warm-up strategies (25:16)General discussion about where anecdotal evidence fits within an evidence-based approach to training, nutrition, or content creation (38:18)Q&A: How to retain muscle while cutting (49:28)Effect of two different weight-loss rates on body composition and strength and power-related performance in elite athletesSystematic Review and Meta-analysis: When One Study Is Just not EnoughLean mass sparing in resistance-trained athletes during caloric restriction: the role of resistance training volumePeople to follow on social media (1:12:58)Ben Patrick, Ben Carpenter, Claire Zai, Emma Storey-GordonTo Play Us Out: Media recommendation (1:24:41)Under the Banner of Heaven

Today’s episode features a big milestone in Greg’s Road to the Stage update, followed by a Research Review that’s sure to stir up some controversy and debate. Researchers recently reported that a little bit of resistance training is associated with lower risk of chronic disease and mortality, but doing more than 2-2.5 hours per week appeared to be considerably worse than doing only 30-60 minutes per week, and potentially worse than doing none at all. In this Research Review, Greg gets to the bottom of it and provides some tentative but practical conclusions. After that, Greg and Eric answer a few questions from listeners, covering topics including potential sleep disruption from pre-bed meals, cannabis for lifters, creatine timing, what to do when you’ve met your daily protein target but you’re below your total calorie target, the way overhead press strength scales with body weight, consequences of insufficient protein intake, how volume for one muscle influences hypertrophy for other muscles, and the role of debates in evidence-based fitness. To close out the show, Eric presents his second (but very disappointing) installment of the fan-favorite segment, “Eric’s Seder Stories.” SUPPORT THE PODCASTReceive our Research Spotlight newsletter, and check out our Facebook group and subreddit.MacroFactorIf you want to learn more about our MacroFactor diet app, check it out  here.To join in on the MacroFactor conversation, check out our Facebook group and subreddit.MASS Research ReviewGet a free 130-page issue of MASS Research Review.

This is the final episode of 2020, and it’s a science-heavy episode packed full of information. After some Good News and Feats of Strength, Eric revisits a couple of previous segments and social media posts about optimal protein intakes and the potential benefits of fish oil. Greg got some new information about a paper evaluating the use of strength blocks to increase hypertrophy, so he revisits that topic as well. Finally, Greg and Eric share some new research reviews about the importance of muscle glycogen depletion for lifters and biological factors that may limit the growth of muscle fibers, followed by a sincere “thank you” to close out the year.If you’d like to receive Research Roundup emails, please sign up for our email list at https://www.strongerbyscience.com/newsletter/. To join in on the SBS conversation, check out our new Facebook group and subreddit.Facebook Group: https://www.facebook.com/groups/StrongerByScienceCommunity. Subreddit: https://www.reddit.com/r/StrongerByScience/. Finally, next time you stock up on supplements from BulkSupplements.com, be sure to use the promo code “SBSPOD” (all caps) to get 5% off your entire order. TIME STAMPSIntro/Announcements (0:00:41). Good news (0:01:08). Big Ramy: https://barbend.com/big-ramy-wins-the-2020-mr-olympia/. Possums: https://www.bbc.com/news/av/world-australia-55240839. Feats of Strength (0:06:16). Clarifications, Rigid Defensiveness, and Aggressive Counter-Attacks (0:16:28). Protein (0:16:55): Studies discussed: Dose–response relationship between protein intake and muscle mass increase: a systematic review and meta-analysis of randomized controlled trials. A systematic review, meta-analysis and meta-regression of the effect of protein supplementation on resistance training-induced gains in muscle mass and strength in healthy adults. Fish oil (0:46:41): Studies discussed: Marine Omega‐3 Supplementation and Cardiovascular Disease: An Updated Meta‐Analysis of 13 Randomized Controlled Trials Involving 127 477 Participants. Are There Benefits from the Use of Fish Oil Supplements in Athletes?

SummaryToday’s episode features some Good News and Feats of Strength, followed by a huge Research Roundup to get you all caught up on recent happenings in the world of exercise science and sports nutrition. Topics covered include optimal protein intake, essential amino acids, meal timing, lactate, relationships between sleep and hunger, and muscle memory. Greg also discusses a recent study suggesting that adding strength phases to your training may promote greater hypertrophy. This study has made the rounds on social media and been widely discussed in the evidence-based fitness world, but there are some important details to consider before drawing conclusions on the topic. Finally, to play them out, Eric and Greg discuss some major food controversies that have shaken Eric to his core.LinksIf you’d like to receive Research Roundup emails, please sign up for our email list. To join in on the SBS conversation, check out our new Facebook group and subreddit.Finally, next time you stock up on supplements from BulkSupplements.com, be sure to use the promo code “SBSPOD” (all caps) to get 5% off your entire order.Time StampsIntro/Announcements (0:01:00). Good news: COVID vaccines, open science (0:04:12). Feats of Strength (0:17:16). Research Roundup (0:24:33). Optimal Protein Intake (0:25:15). Article discussed: Dose–response relationship between protein intake and muscle mass increase: a systematic review and meta-analysis of randomized controlled trials. Essential Amino Acids (0:35:39). Article discussed: Essential Amino Acids and Protein Synthesis: Insights into Maximizing the Muscle and Whole-Body Response to FeedingMeal Timing (0:42:55). Articles discussed: Late eating is associated with cardiometabolic risk traits, obesogenic behaviors, and impaired weight loss. Higher eating frequency is associated with lower adiposity and robust circadian rhythms: a cross-sectional study. Impact of Meal Frequency on Anthropometric Outcomes: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials. Danny Lennon’s article on chrononutrition. Preceding a Hypertrophy Phase with a Strength Phase (0:52:22). Article discussed: Is stronger better?

We recently had a class on how to read research articles, and many course materials laid out processes that would take about 5-6 hours for every single paper. What is your process for reading research? Does this change when you’re trying to get acquainted with a whole new body of literature versus evaluating a single paper on a familiar topic? 

Today’s episode starts off with a Good News segment and some brand new Feats of Strength. After that, Eric discusses his most recent SBS article about Betaine, and addresses some of the feedback that the article has received. This segment opens up into a broader discussion about how to evaluate a new body of research as it’s developing. Topics include conflicts of interest, how much evidence is required to justify experimentation, and when we can confidently conclude that an intervention simply doesn’t work. Some historical examples are discussed along the way, with some background information about how the steroid, creatine, caffeine, and citrulline malate literature developed over time. After that, Greg and Eric share a quick Research Roundup segment, followed by some off-topic questions To Play Them Out. If you’d like to submit a question for a future Q&A segment, please go to tiny.cc/sbsqa. If you’d like to recommend someone for a future “On the Rise” segment, please go to tiny.cc/creators. If you’d like to receive Research Roundup emails, please sign up for our email list at https://www.strongerbyscience.com/newsletter/.  TIME STAMPSAnnouncements (0:01:14). Good news (0:02:44): SBD replacing Metal singlets and DL socks for lifters who bought them in the past year.Bionic Eye, As Sensitive as The Human Retina, May Give Sight to Millions: https://www.goodnewsnetwork.org/bionic-eye-sensitive-as-a-human-retina-may-give-sight-to-millions/.  Simple Injection Could Be the Cure for Wrestlers and Athletes Suffering From ‘Cauliflower Ear’: https://www.goodnewsnetwork.org/injection-could-cure-cauliflower-ear/. Feats of Strength (0:10:16). SBS Article Discussion: Betaine (0:19:58): https://www.strongerbyscience.com/betaine/. Broader discussion on research interpretation (0:26:14).

Greg and Eric’s plans to morph the show into a political podcast have met an untimely end, but the show must go on. In today’s episode, they discuss some totally unsubstantiated claims about the coronavirus, also known as COVID-19, followed by some impressive Feats of Strength. After that, Eric shares a research review about how the timing of your meals may alter the metabolic response to feeding, then Greg shares a research roundup about energy expenditure during times of vigorous mental effort, antagonist stretching for strength and power, and using heart rate variability to gauge your recovery from lifting. Then, Greg and Eric answer a few listener questions, share a very tentative recommendation for the “On the Rise” segment, and share a very confident recommendation for the “On the Rise” segment. To close the episode, Greg discusses some of his favorite sources of fun, informative educational content that is not fitness related, and Eric one-ups him by sharing the only source of information a person would ever need.If you’d like to submit a question for a future Q&A segment, please go to tiny.cc/sbsqaIf you’d like to recommend someone for a future “On the Rise” segment, please go to tiny.cc/creators – TIME STAMPS –New program for sale: Average to Savage 2.0: https://www.strongerbyscience.com/average-to-savage/ (0:00:59). Lamenting the untimely terminations of the Klobuchar and Bloomberg campaigns (0:05:30). Coronavirus (COVID-19) impacts the fitness world (0:07:29). Article from Beth Skwarecki: https://vitals.lifehacker.com/no-the-keto-diet-wont-give-you-special-protection-from-1842057362.  Feats of Strength (0:13:20). Research Review: Twice as High Diet-Induced Thermogenesis After Breakfast vs Dinner On High-Calorie as Well as Low-Calorie Meals (0:21:03). Study: https://academic.oup.com/jcem/article-abstract/105/3/dgz311/5740411?redirectedFrom=fulltext. SBS Guest Article by Danny Lennon: https://www.strongerbyscience.com/chrononutrition/. Research Roundup (0:35:31). The stress of chess players as a model to study the effects of psychological stimuli on physiological responses: an example of substrate oxidation and heart rate variability in man: https://www.ncbi.nlm.nih.gov/pubmed/18987876. Effect of acute antagonist static stretching on upper-body agonist power: https://journals.sagepub.com/doi/full/10.1177/1747954119884441. Profiles of Heart Rate Variability and Bar Velocity following Resistance Exercise: https://journals.lww.com/acsm-msse/Abstract/publishahead/Profiles_of_Heart_Rate_Variability_and_Bar.96369.aspx. Q&A (0:59:44).  Advice for reducing the interference effect for recreational lifters?

How do I know if I am strong enough to be messing with bodybuilding-style training and accessory work? Should I just be focused on getting stronger until my main lifts are more competitive?0:14:20 There has been a lot of discussion about bulking on recent shows. I would be interested in hearing about practical recommendations regarding the frequency of bulking and cutting. How often is common? Is there a ceiling where it's no longer effective, or even harmful, over a given time period?0:29:57 Two questions:I've noticed that as my lifts have gotten stronger, my rest periods are becoming longer. What's the mechanism behind that?What does the literature say about rest time between sets for maximizing hypertrophy versus maximizing strength? Is it possible to take too much or little?0:52:18 Rank these sports in order of difficulty and competitiveness: men's natural bodybuilding, men's natural classic physique, baseball, basketball and football.0:55:09 Is body mass index (BMI) still accurate for people who are much taller (or shorter) than average?1:05:53 Is completely eschewing the deadlift and all deadlift variations acceptable from a bodybuilding standpoint? If so, can you name a couple of accomplished bodybuilders who have reached their level without incorporating deadlifts into their training? To what extent can I make up for deadlift gains with a bunch of other exercises targeting the posterior chain, forearms, and upper traps?1:12:45 I’ve been trying to get more sleep (at least 8-9 hours or more per night). However, I typically end up either waking up earlier or waking up more frequently throughout the night, resulting in poorer sleep than normal. Is this a sign that I shouldn't be trying to force more sleep, and should return to my typical sleep habits?1:22:06 Are you ever concerned about a client having high creatinine levels? 1:27:00 I once heard Greg say that one reason he's never taken anabolic steroids is their potential impact on cognition, but I've never seen anyone else reference that as a side effect. Could he elaborate?1:37:13 More and more studies show that a plant based diet is healthier than one that includes meat and other animal products. How does this relate to gains and weight loss?1:48:18 I was wondering if you guys could provide any advice for students looking to improve their writing skills for science-based fitness articles. Related to that, what would be a useful approach for getting published on well-known websites?
