Wits & Weights | Evidence-Based Fitness & Nutrition for Lifters Over 40

Is high protein just another fad diet?

Learn about the 3 criteria that define a fad, how protein performs against each one, the research on lean mass and strength training, the mechanisms behind protein's thermic effect and satiety, and why the case gets stronger for adults over 40.

This episode covers the fad diet framework, research updates on protein and muscle building, the thermic effect on your metabolism and the satiety r...

Should you fix your diet or your training first?

You've probably heard that diet is 80% of the results, so nutrition is the obvious place to start. After all, "abs are made in the kitchen" right? The problem is this claim has no basis in science, and for a lot of you, training is the actual bottleneck.

The real answer depends on which part of your system is the weakest link right now. 

Learn about the research on resist...

Your fat loss plan isn’t broken! The real problem is what happens in the 10 seconds before you order, snack, or say “screw it” after a stressful day.

Learn an under-discussed truth about nutrition and fitness progress: the gap between a solid plan and real-life execution is where most people "fall off track" and lose momentum.

This episode covers a structural gap when it comes to food decisions in the context of t...

You eat clean, cook at home, and choose whole foods, so why can’t you lose fat? Are your macros and portions quietly keeping you stuck?

You’ll learn why food quality matters, but quantity still drives weight loss, muscle building, and performance. We ...

Bulking, cutting, bulking, cutting. If you've been through that cycle and ended up further from your goal than when you started, there's a reason the yo-yo keeps repeating, especially over 40.

Learn about the metabolic adaptation and hormonal changes that make long diet phases more difficult (and sometimes unsustainable), a creative approach called intermittent dieting (not to be confused with intermittent fasting), a very...

What supplements help with stress, sleep, and recovery after 40?

The honest answer is a very short list of compounds with clinical evidence behind them, specific doses, mechanisms that matter for body composition, and specific safety profiles.

This episode covers 5 compounds with clinical evidence for stress, mood, sleep, and recovery in adults over 40 who do strength training to lose fat and build muscle. Learn about the forms and d...

Your fat loss, your muscle, your heart, your inflammation, what happens to your weight when you stop, and long-term safety.

This episode covers body composition data from the 2026 semaglutide and tirzepatide trials, cardiovascular outcomes from SELECT and SURPASS-CVOT, inflammation findings beyond weight loss, weight regain patterns after stopping, and a 5-part framework to keep muscle ...

How much lifting is too much vs. too little? What about cardio? And how hard does your body fight back when you try to out-exercise your diet?

Exercise physiologist and clinical nutrition expert Ben Brown breaks down why exercise is often a weak tool for weight loss, even when you are lifting weights and doing everything “right.” 

We unpack metabolic compensation, how stress after 40 changes your results, and why nutrition and fitnes...

Do you need yoga, stretching, or "mobility work" to stay flexible. Does lifting weights make you "stiff" or does it improve flexibility?

We examine 3 recent studies that compared resistance training to stretching for flexibility, and their findings challenge everything most people assume about lifting weights and mobility.

Philip covers the "lifting makes you stiff" myth and a training approach that buil...

Intermittent fasting is still the most popular nutrition advice on the internet. 

Skip breakfast, shrink your eating window, lose weight. But if you're over 40, this may not give you the results you want. It could even backfire.

Learn about the 5 specific ways intermittent fasting can backfire when your goal is losing fat and building muscle after 40. Philip examines a 2025 meta-analyses comparing IF to standard dieting, the cha...

You spent months building muscle, and now you're ready to cut. Or you're on a GLP-1 medication and losing weight but not sure how much muscle your'e also losing.

In this bonus episode, Philip nerds out on the exercise equipment and nutrition plan NASA chose for the first crewed lunar mission in over 50 years, including how they stay strong and preserve muscle (hint: compoun...

Why does lifting start hurting once you hit 40? Is it really age, or is your body compensating for weak links you cannot see?

Chris Duffin joins me to unpack the biomechanics behind strength training longevity, muscle building, and injury prevention. Chris is a world record strength athlete who has squatted and deadlifted over 1,000 pounds while applying engineering principles to human movement.

You've been showing up to Pilates, yoga, or barre for months, maybe years, and your body composition hasn't changed. You're not getting stronger.

And if you're over 40, the muscle and bone you need most may be slipping away while you work hard at the wrong thing.

Building muscle and maintaining bone density after 40 requires two specific things from your training: mechanical tension and proximity to failure. Pilat...

How many times have you sworn “this time will be different” only to end up right back at square one? 

New program, new diet, new macros, new Monday. And every time, the results faded.

Why does this keep happening to people (like you!) who are already disciplined, consistent, and willing to put in the work?

The issue isn't effort or information. Listen in to find out what it is.

You've been eating 1200 calories, working out, and the scale won't budge. 

The advice you keep getting is to eat even less, but that's the problem.

If you're over 40 and stuck despite doing "everything right," your body is probably caught in the undereating trap. 

Chronic low-calorie dieting suppresses your metabolism, burns muscle instead of fat, and disrupts the hormones that control where you store fat...

Yet again, you're motivated to make a change. You've given yourself 6 months, you pick a program, cut calories, and go after it!

Then (inevitably) the whole thing falls apart about 1-2 months in (maybe even sooner).

Most people over 40 who want to lose fat and build muscle start with the wrong first step. They jump straight into a calorie deficit before they even know what their body is doing.

This episode lays out a complet...

I’m joined by Cori Lefkowith, founder of Redefining Strength, certified trainer, former Division I athlete, and powerlifting champion, to unpack why macros, nutrition, and strength training are powerful tools for body recomp when used the right way.
