Join Physique University to get a personalized nutrition plan to look and feel better and stop guessing about your calorie needs: bit.ly/wwpu-free-plan

Why do some people thrive on far fewer calories than others (who might be miserable eating at that level)?

When we talk about whether 800 calories a day is "unsafe," we're asking the wrong question. After all, your size, training, activity level, and energy needs are unique to you and can vary widely among the population.

Learn why there's no universal unsafe calorie number, how to determine your own metabolic limits using biofeedback, and the critical trade-offs between aggressive deficits and sustainability. 

Main Takeaways:

• There's no universal "unsafe" calorie number
• Metabolic adaptation is real but reversible, not permanent "damage"
• Use biofeedback (energy, sleep, strength, mood) as your personalized guide rather than arbitrary rules
• The trade-offs between speed, sustainability, and metabolic preservation require intentionality

Are GLP-1 medications like Ozempic, Wegovy, and Mounjaro stealing your hard-earned muscle?

The short answer is no, but the reality is more nuanced than many realize.

Learn why people experience muscle loss while taking weight loss medications. Weight loss medications can be incredible tools when used properly, but like any tool, they work best when combined with fundamental lifestyle strategies that optimize body composition.

Can your smartphone really rival a $100,000 DEXA scan? What if the same device you use to scroll Instagram could also reveal your body fat percentage, fat distribution, and even your HRV?

I sit down with Jason Moore, founder and CEO of Spren, a company turning your phone into a precision biometric tool. We talk about how Spren compares to gold-standard lab equipment, why body composition tells you more than scale weight ever could, and why tracking trends is often more important than chasing perfect numbers. This conversation will show you how technology can bring lab-grade insights straight to your pocket.

Today, you’ll learn all about:

2:36 – Why body composition matters
6:56 – How a phone measures fat
10:55 – Accuracy versus precision explained
14:38 – Lean mass and muscle changes

Is your strength training actually building muscle?

Scale weight fluctuates, body fat measurements are inconsistent, and progress photos depend on lighting and angles.

There's one metric that cuts through all this noise:

Fat-Free Mass Index (FFMI)

It shows your actual muscle development regardless of whether you're carrying extra fat or feeling bloated, and once you understand yours, it changes everything about setting goals and how to focus your training.

Most lifters have never heard of FFMI. Unlike body weight or even body fat percentage, FFMI isolates your actual muscular development from everything else, giving you clarity about your progress that no other measurement can.

Main Takeaways:

• FFMI measures your muscularity independent of body fat percentage
• Two people with the same training experience can have vastly different FFMI numbers, requiring completely different approaches
• Building muscle takes years, while losing fat takes months, so you need a more precise way to track this
• Your FFMI determines whether you should prioritize muscle building or fat loss (vs. your feelings or the mirror)

You've been told that belly fat gain during midlife is inevitable... just part of aging and declining hormones that you have to accept.

Recent research from the landmark SWAN study that followed 308 women for 12 years reveals the truth: "menopause belly" isn't random aging.

It's a specific, predictable hormonal reshaping of where your body stores fat that begins 3 years before menopause and can be prevented and reversed.

Discover the exact timing windows when intervention works best, why some women don't experience this shift at all, and the science-backed strategies that can help you take control of your body composition during this transition... no matter where you are in the process.

Main Takeaways:

• Menopause belly is a measurable shift from protective fat storage (hips/thighs) to dangerous visceral fat around organs (not just general weight gain)
• Fat redistribution accelerates dramatically during the menopause transition but begins up to 3 years earlier
• You can prevent and reverse this fat redistribution

This week in my Instagram feed, I shared 2 critical principles that determine if your nutrition plan will actually work for fat loss and muscle building in real life, such as:

• When life is at its messiest, not just when everything is perfect
• Dealing with social events, travel, and celebrations (birthday cake!)
• Eating more but not eating more calories
• Making fat loss easier and more sustainable

Follow me on Instagram @witsandweights to read more pithy, nerdy, out-of-the-blue, but ultimately helpful (i.e., practical!) thoughts on fat loss, nutrition, training, diets, behavior, psychology, and more.

Send me a DM letting me know which principles resonate with you and how you plan to implement them!

Joe shares what your genes can actually tell you about building muscle, losing fat, and preventing disease, and where the industry is misleading you. We also dig into how combining genetic data with lab work creates actionable steps you can measure and adjust over time.

Tune in to discover whether your DNA could be the missing piece in your fitness journey.

Stop letting inaccurate metabolism estimates sabotage your nutrition goals. 

The fitness industry has convinced us that estimating metabolism requires expensive tests, fancy gadgets, or complex formulas, but there's one method that cuts through the noise using evidence, engineering, and efficiency.

Your fitness tracker says you burned 3,200 calories, online calculators recommend 2,400 for maintenance, and your metabolic test shows 1,850 RMR. They're all probably wrong.

Discover the one method gives you your actual daily calorie burn with scientific precision so you can run your next fat loss or muscle building phase confidently and with success.

Main Takeaways:

• Your metabolism has 4 components that fluctuate constantly
• Online calculators can be off by 300-600 calories per person
• Fitness trackers have 27-93% error rates for energy expenditure
• The only accurate method is to track calorie intake + trend weight over 3-4 weeks to reverse-engineer your actual TDEE
• This approach is self-correcting, personalized, adaptive, and works even with imperfect food logging

Think you need a calorie deficit to lose fat? Or months of bulking followed by months of cutting to reshape your physique?

Think again.

Body recomp (the simultaneous loss of fat and gain of muscle) isn't just possible... it's achievable for most people under the right conditions. 

Your body can become remarkably efficient at energy partitioning, directing nutrients toward muscle growth while mobilizing stored fat for fuel. 

This episode breaks down exactly how this works: how your body can simultaneously burn fat and build muscle, often without scale changes.

Learn who can achieve this "impossible" feat and how to do it.

Main Takeaways:

• Body recomp is simultaneous fat loss and muscle gain, possible even at maintenance calories
• Your body actively partitions energy based on training stimulus and protein intake
• Beginners, detrained individuals, and overweight people have the highest recomp potential
• Scale weight becomes virtually useless - track strength, measurements, and photos too

Tired of cutting and bulking (or just don't want to)? Frustrated with approaches that leave you either feeling too fluffy or too depleted?

Is there a middle ground that works instead?

Yes, it's called body recomposition or "body recomp" where you build muscle and lose fat at the same time.

Most people get stuck in the cut-bulk cycle, never feeling satisfied with where they land.

But body recomposition offers a smarter approach: a method that fuels muscle growth while still allowing for fat loss.

What You'll Learn:

• Why the scale lies during body recomp
• The 3 biggest myths keeping you stuck
• How "aggressive maintenance" works
• What metrics actually matter for tracking progress
