The Human Formula

What if everything the health industry told you was designed to keep you buying - not thriving?

Pills. Supplements. Complicated diets. Hour-long workouts. The industry sells you an endless stream of solutions to a problem it quietly created: the belief that your body is broken and needs fixing from the outside.

It isn't. And the proof has been hiding in your biology all along.

The Formula They Don't Want You to Find

After training in biomedical engineering at a QS Top 100 university and UNC Chapel Hill, John McKenna became obsessed with a single question: what is the smallest set of inputs that produces the longest, healthiest human life?

Nearly two decades of research, self-experimentation, and relentless data collection later - he found the answer. And it didn't come from a lab. It came from his identical twin brother.


Same DNA. Same genetics. Dramatically different health outcomes - explained entirely by a handful of simple, consistent daily inputs. The twin experiment gave McKenna something no clinical trial can manufacture: a living, breathing control group. And what the data showed was both surprising and liberating.

The industry got it wrong. Here's what the science actually says.

Inside The Human Formula, McKenna dismantles the most persistent myths in health - the ones costing you energy, results, and years of your life. You'll discover the truth behind:

The "8 hours of sleep" rule - and why the number is almost beside the point
Breakfast as the most important meal of the day - the real story is far more interesting
Long workouts as the path to longevity - and what actually moves the needle
Melatonin, supplements, and the pill-first culture - and what your body is quietly losing every time you reach for them
Sugar cravings, willpower, and why you keep losing that battle - the cause is not what you think

One system. Three pillars. Zero guesswork.

The Human Formula covers Sleep, Nutrition, and Movement - not as three separate topics, but as one integrated biological system governed by the same ancient circadian machinery your body has always run on. Each chapter translates cutting-edge science into habits so simple and so grounded in how humans evolved that they feel less like a program and more like a return to something you already knew.

No supplements required. No expensive technology. No obsessive tracking. No gym membership necessary.

Just the formula - and the understanding to make it stick for life.

"Health is not complicated. The industry just needs it to be."

- John McKenna


If you've ever suspected the health world was making things harder than they need to be - you were right.

It's time to stop buying the complexity and start living the formula.
