Kevin, now on the NEXE team, went from about 200 lb to 158.
Siyuan's LDL cholesterol went from 141 to 87.
Slava's vitamin D went from 27.5 to 59.7 in about six weeks.

Nobody Ever Opened The Hood

Every plan you've tried told you what to do before anyone checked what was going on inside you.

You wouldn't fix a car by guessing which part is broken. You'd open the hood first. The Lean Code is that first look: testosterone, cortisol, thyroid, insulin and a few key nutrients, and what to change first.

Case Studies: Bloodwork First

Four men over 30. Four different problems. Same first step: check the bloodwork, then build the plan around their numbers and their life.

Kevin

Cybersecurity engineer, now on the NEXE team

200 lb to 158 lb. Kept off for two years.

1The problem
Seven years of keto, carnivore and fat burners. He trained six days a week and still couldn't get lean.
2What his bloodwork showed
He was eating too little and training too much. His bloodwork showed a body running on empty.
Marker Before After
Blood sugar High Healthy
Cholesterol Poor Healthy
3What we changed
More food, not less. Training cut to three short workouts a week, built around his work hours. We tracked his markers every quarter.
4The result
200 lb to 158 lb, and he's kept it off for two years. His markers moved back into healthy ranges.

Why it worked: He stopped fighting his body, and every change was based on his own numbers.

Kevin was NEXE's first client. Today he works on the NEXE team.

Siyuan

Sales

Cholesterol flagged high. Both back in range.

Siyuan progress photos: 200 lb and 25% body fat, then 183 lb and 13.5%

Read Siyuan's full case

1The problem
He trained and ate well, but his last lab report had his LDL and total cholesterol both flagged high.
2What his bloodwork showed
Both cholesterol numbers were above range.
Marker Before After
LDL cholesterol 141 87
Total cholesterol 212 172
Body fat 25% 13.5%

3What we changed
We built his food and training around those numbers, then retested.
4The result
By his next test both were back in range, and he went from 200 lb to 183 lb.

Why it worked: We started with what his labs said, not with a generic diet.

Slava

Entrepreneur

Reached 174 lb in 6 months and kept it off.

Read Slava's full case

1The problem
He'd already leaned out once with another coach. Then the weight came back.
2What his bloodwork showed
His old plan was too strict to keep. And his vitamin D was below range.
Marker Before After
Vitamin D (ng/mL) 27.5 59.7
Free testosterone (pg/mL) 32.8 39.3
Body weight 196 lb 174 lb

Tap any report to see it full size.
3What we changed
We loosened his diet so it stopped feeling like a diet, added vitamin D, and retested six weeks later.
4The result
Vitamin D back in range in about six weeks, and 174 lb in six months.

Why it worked: We found what the scale couldn't show, then gave him a plan he could live with.

Alex

Firefighter

242 lb to 210.6 lb, through knee surgery.

Read Alex's full case

1The problem
He hurt his knee fighting the LA fires and needed surgery. He was 242 lb at 6'2", training six days a week with nothing to show for it.
2What his bloodwork showed
His blood sugar and cholesterol were both above range.
Marker Before After
Blood sugar High Healthy
Cholesterol Poor Healthy
3What we changed
Less gym time, more focus. Training worked around his knee rehab. Food he likes, burgers and Chipotle included. Quarterly bloodwork to track his markers.
4The result
242 lb to 210.6 lb in about seven and a half months, through surgery and rehab. Back on duty, with healthy markers.

Why it worked: We built the plan around his real life and his real numbers, injury included.

I Trained Hard And Ate Clean. My Body Still Wouldn't Change.

Daniel before, at 205 lb — Before · 205 lb

Daniel after, at 165 lb and 8% body fat — After · 165 lb · 8% body fat

I did what I'd been told: train harder, eat less, add more cardio. I sat at 205 pounds and just got more tired.

Then I got proper bloodwork done, and it explained what years of dieting couldn't. I built my food, training and recovery around my results, got down to 165 pounds at 8% body fat, and kept it off.

That's why every NEXE client starts with bloodwork, and why The Lean Code starts there too.

Questions

Who is this for?

Men over 30, in their 30s, 40s or 50s, who've tried the diets and the extra cardio and want to know what's actually going on before trying again.

Who is it not for?

If you want a pill, a 30-day shred or someone to do it for you, this isn't it. The Lean Code shows you where to look and what to change. You still do the work.

Do I need a blood test first?

No. Start the lessons today. Lesson two shows you exactly what to ask for when you do test.

Does it include coaching or a review of my results?

No. It's a self-guided course. If you want help applying it, you can book a free call with our team from inside. That's optional.

I've tried courses before. Why this one?

Most courses hand you a plan. This one starts one step earlier, with what your body is doing, so the plan fits you instead of everyone.

What's the free Accelerator Call?

A chat with our team about coaching, if you want it. It's optional, there's no pressure, and you keep the course either way.

Is it a subscription?

No. One payment of $27. Nothing recurring.

You've Already Tried The Harder Diet.
