Welcome to 4 Minute Fridays, my weekly newsletter, where I reveal cutting-edge tips to help you get lean, boost energy, and live longer.

What's in store for today:

• How I fixed my metabolic health at 46
• The worst time to eat for your body (not what you think)
• A book that shaped how I coach clients

Hey friend,

Improving your health is a marathon with sprints in between, but most people treat it like a 100-meter race.

What’s worked for me is framing health in 3 to 6-month blocks:

• Get the data: track your blood work, weight, inches, and energy.
• Find the one bottleneck holding you back and work on it.
• Once fixed, move on to the next.

That’s exactly how I fixed my metabolic health, which you’ll read about in a minute.

It took 3 years of stack sprints, not one heroic push. The people who win this game are not the ones who go the hardest, they’re the ones who keep showing up over the long tail and keep playing.

Here's what caught my attention this week.

Here is your 4 Minute Friday:

1. How I Improved My Metabolic Health At 46

A year and a half ago, I thought I was healthy, but I got a blood test that slapped me in the face.

It showed I was drifting towards becoming prediabetic with my fasting glucose at 102. HbA1c at 5.7%.

Today, at 46, my markers look better than most men half my age. Fasting insulin at 4.6 (optimal is under 5). HOMA-IR at 1.10. Glucose and HbA1c are back in the healthy range.

Here's what actually moved the needle:

1. A small, sustained caloric deficit. Not a crash diet. A modest gap held for 12 months. Fat loss is the most powerful metabolic intervention that exists. Nothing else comes close.
2. Less alcohol. I didn't quit. Just shifted from habitual to occasional.
3. More fiber. Psyllium husk did a lot of the heavy lifting here. 10 grams a day.
4. Heavy lifting through the deficit. Muscle is your largest site of glucose disposal. Losing weight without lifting shrinks your metabolic engine with you.
5. 7.5+ hours of sleep. One night at 5 hours can tank insulin sensitivity 25% the next day.

What I didn't do: extended fasts, keto, berberine, metformin, GLP-1s, cold plunges, or anything exotic.

Most people are looking for the thing nobody's told them yet. The truth is the opposite. Everything that works, you've already heard. You just haven't done it for long enough.

2. The Body's Worst Time To Eat (It's Not When You Think)

You're not just what you eat, you’re when you eat. Your body’s ability to handle food changes throughout the day, and if your metabolism is already struggling, nighttime is when the wheels come off.

A new study out of Oxford tracked people with fatty liver disease across the day and night using advanced metabolic testing. What they found was crazy.

At night, 3 things went wrong at once:

1. Their cells became more insulin-resistant
2. Their pancreas secreted less insulin
3. Their liver dumped more glucose into the bloodstream

Healthy people didn't show this pattern. Only people with existing metabolic dysfunction.

The crazy part? The nighttime problems persisted even after participants lost weight and saw their liver health improve.

Late-night eating might be doing more damage than you think. Especially for people with metabolic issues, a large evening meal might be a bad idea because their body isn't built to process sugar and fat efficiently later on in the day.

The fix to this is front-loading your calories. Bigger breakfast, bigger lunch, lighter dinner. Stop eating 3 to 4 hours before bed.

If you're metabolically healthy, this matters less. If you're not, it matters a lot.

Your liver works the day shift. Stop asking it to pull doubles.

❤️ My Favourite Thing this Week

20+ years ago, when I was just starting out in fitness, I bought a then-obscure ebook called Burn the Fat, Feed the Muscle by Tom Venuto.

It changed how I thought about the entire game.

At the time, every fitness magazine was selling 30-day transformations, fat-burning pills, and whatever protocol the latest pro bodybuilder was doing. Tom did the opposite. He laid out a framework built on 4 boring pillars: nutrition, mindset, resistance training, and cardio.

The whole premise was that fat loss is a skill you build, not a sprint you survive. He was preaching sustainability before the rest of the industry caught up.

What I took from it back then is the same thing I teach clients now. Calories matter. Protein matters. Lifting matters. Cardio is a tool, not the answer. And the mental game is the one that decides if any of it sticks.

If you're new to fitness, or you've been doing this for years and want to go back to first principles, this is one of the few books still worth reading two decades after I first picked it up. You can check it out over here.

Client of the week - Constantin, Business Owner

Constantin is a business owner who is committed to staying consistent, no matter where life or work takes him.

He’s now down 46.3 lbs, lost 7.87 inches off his waist, and is seeing a major transformation in both his physique and overall health, all while staying consistent with his workouts and nutrition at home and on the road.

The most impressive part? He’s achieved these results without even reaching the halfway point of the program yet, proving what’s possible when the right habits are practiced consistently.

Here’s how we did it:

• Built a sustainable nutrition plan that works anywhere
• Prioritized strength training and consistency over perfection
• Created systems that made staying on track during travel simple and realistic

Constantin is already seeing incredible results, and he's just getting started. Amazing work, Constantin!
