Wits & Weights | Strength Training & Fat Loss Over 40

It turns out that carb cycling does NOT improve fat loss or your metabolism. But does it have other benefits?
You've heard you should load carbs on lifting days and cut them on rest days, especially after 40. Where did this idea come from?
I'm breaking down the one study that comes closest to testing carb cycling and what happened when a second group of researchers reanalyzed the data. You'll also hear why the insulin and fat storage argument doesn't hold up, what one study found about insulin sensitivity after menopause, and the number of hard sets that determines whether carbs before training do anything for you. 
Where carb cycling comes from and why it spread beyond bodybuilding 
The Campbell 2020 refeed study (and later reanalysis)
Why insulin and “storage hormone” arguments do not predict fat loss under matched calories 
What leptin and metabolic flexibility claims get (partially) right
What research suggests about menopause, insulin sensitivity, and body fat as the driver
How to set weekly calories, daily protein, and fiber before worrying about carb timing
When pre-workout carbs matter most, and fed vs. fasted training
Why underfueling and low-carb patterns can backfire for recovery and your relationship with food 
If you want to stop earning your carbs and put them where your week needs them, hit play.

Do you actually need 8 hours of sleep to build muscle after 40?
We put that claim under the microscope and separate what sleep research actually shows from what fitness culture spreads online.
Learn about the simple rules that protect your strength training, fat loss, and daily energy even when your night falls a bit short:
Where the 7+ hours of sleep guideline comes from and what it does and does not cover
The effect of sleep restriction on a calorie deficit, including fat loss vs fat-free (lean / muscle) mass loss
Why “short sleep kills your gains” is not supported by direct lifting trials, and what mechanistic data suggests instead
How cutting sleep often affects your sedentary time more than gym performance
Why sleep regularity can matter more than duration for long-term health outcomes
Wow to use wearable data without letting sleep scores drive stress and bad decisions
3 practical rules for bad sleep days
The simple movement targets that offer big returns and 2 quick strategies to offset extra sitting (which is connected to sleep)

The claim that women need more creatine is everywhere right now, especially if you're strength training over 40.
Maybe you heard that women carry 70 to 80% lower creatine stores than men, so you need a bigger dose.
What about bone health (especially in postmenopause), brain health, and loading? How much should you actually take and when? What will creatine do for you?
Get those answers and more, including:
The REAL reason creatine works
Why “lower creatine stores” does not mean depleted muscle creatine
How sex-specific high-dose claims fall apart at the tissue level
What the research actually shows for strength and lean mass in older adults and older women
The reality of bone density, cognition, mood, and higher dosing benefits of creatine based on the research
The best type of creatine (hint: it's the cheapest too) and how to dose it
Creatine myths on weight gain, bloating, hair loss, and kidneys (plus how it affects your bloodwork)
If you take creatine, you're thinking about starting, or you've been told you need more of it than men do, hit play.

If 5 to 30 reps can all build muscle, why do some rep ranges clearly work better than others? 

After 40, could the “science-based” advice you’re following be the exact reason your progress has stalled?
I brought strength coach Andy Baker back to challenge one of the most oversimplified ideas in evidence-based fitness: that rep ranges are basically interchangeable.
We break down the five rep ranges you need to understand, from heavy 1 to 4 rep strength work through 20 to 30 rep sets, and exactly where each belongs in your training.
You’ll learn why 4 to 8 reps may be the “meat and potatoes” for getting brutally strong and building muscle, when higher reps make more sense for isolation work and cranky joints, and why the effective reps model gets misunderstood.
Plus, Andy shares his simple 80 percent rule for programming your lifting weights after 40.

A diet break won't give you more fat loss. Two weeks at maintenance won't "reset" or "restore" your metabolism either. 
But I still use diet breaks with almost every client over 40, but for totally different (but beneficial) reasons.
We lay out a simple framework for using maintenance breaks to reduce diet fatigue, improve adherence, and avoid panicking when the scale jumps, including:
Where diet break claims come from, including metabolic adaptation and the MATADOR trial design
What meta-analyses find on fat loss, lean mass, and dropout rates
Why resting metabolic rate is not the whole metabolic adaptation story
