By Measuring the State of My Body and “Tuning” ItUsing Nutrition and Exercise, I Became Healthier

How Did I Get Started? I Arrived in La Jolla in 2000and Decided to Move Against the Obesity Epidemic

I Reversed My Body’s Decline By Quantifying and Altering Nutrition and Exercise

Quantifying My Sleep Pattern Using a Zeo -Increased My Average to 8 Hours/Night

REM is Normally 20% of SleepMine is Between 45-65% of Sleep

An Infant Typically Has 50% REM

Stroke risk increased by sleeping less than six hours a night-M. Ruiter, Sleep 2012

Why Did I Have an Autoimmune Disease like IBD?

Despite decades of research, the etiology of Crohn's disease

remains unknown. Its pathogenesis may involve a complex interplay between

host genetics, immune dysfunction,

and microbial or environmental factors.--The Role of Microbes in Crohn's Disease

Paul B. Eckburg & David A. RelmanClin Infect Dis. 44:256-262 (2007) 

So I Set Out to Quantify All Three!

The Cost of Sequencing a Megabase of DNAHas Fallen Over 10,000x in the Last Ten Years!

This Has Enabled Sequencing of Both Human and Microbial Genomes

I Wondered if Crohn’s is an Autoimmune Disease, Did I Have a Personal Genomic Polymorphism?

To Map Out the Dynamics of My Microbiome Ecology I Partnered with the J. Craig Venter Institute

• JCVI Did Metagenomic Sequencing on Seven of My Stool Samples Over 1.5 Years

• Sequencing on Illumina HiSeq 2000 – Generated 200 Million

100bp Reads

• JCVI Lab Manager, Genomic Medicine– Manolito Torralba

• IRB PI Karen Nelson– President JCVI

From War to Gardening:New Therapeutical Tools for Managing the Microbiome

“I would like to lose the language of warfare,” said Julie Segre, a senior investigator at

the National Human Genome Research Institute. ”It does a disservice to all the bacteria

that have co-evolved with us and are maintaining the health of our bodies.”

Evidence for the Efficacy of Probiotics is IBD is Mixed -More Clinical Research Needed

“...there is virtually no evidence of probiotic efficacy in Crohn’s disease.”
