Tim and Kelly are back with a not-so-perfectly-scientific experiment: creatine, weightlifting, and a little help from Kelly's intern.

In this episode, we discuss:

• Creatine & Lifting: Tim tries daily creatine and a three-day-a-week weightlifting plan.
• Joint Pain & Strength: Tim rates the routine an 8 out of 10 and explains what helped, what still hurts, and what changed.
• The Next Phase: Kelly explains why strength training, protein, and better tracking matter before the next experiment begins.

Whether you're curious about creatine, strength training, or Tim's ongoing role as Kelly's favorite test subject, this episode sets up the next phase of The Barnes Experiment.

Tim’s gut results are in, his sugar cravings are down, and now Kelly has decided it’s time to get "swoll". Kelly (the scientist) has moved Tim (the skeptic) into Phase Two, and this time it involves a lot more than just tracking gut microbes.

In this episode, we discuss:

• The Nutrition Review: Tim shares how months of probiotics helped "fill the gaps" and remarkably reduced his sugar cravings.
• Creatine for Brains & Brawn: Why Kelly is using creatine not just for the gym, but for its potential cognitive and mental health benefits.
• Phase 2 — The Resistance Protocol: Kelly details a 4-week progressive training load, including taking baseline measurements of Tim's biceps and quads.
• "Health Poisoning": Kelly defends her methods of slipping acacia fiber, Akkermansia, and even ground-up kimchi into Tim’s meals to support his microbiome.

Whether you’re interested in the science of muscle protein synthesis or just want to hear Tim complain about eating "tree bark" (acacia fiber), this episode explores how specific supplements and lifting can reshape your data.

What happens when a research scientist tests her skeptical husband’s gut health? You get a 3 out of 10 score and a lot of explaining to do.

In part two of our gut health series, Kelly finally reveals Tim’s microbiome test results, and it’s a wake-up call. From a "severe phyla imbalance" to a complete absence of the "gold star" beneficial bacteria, we look at the raw data behind Tim's chronic inflammation, skin issues, and gout.

In this episode, we discuss:

• The "3 out of 10" Score: Breaking down the four key markers: Phyla balance, diversity, beneficial species, and pathogenic species.
• The GLP-1 Connection: How a damaged gut microbiome impairs your body’s natural appetite regulation (and what that means for weight management).
• Leaky Gut & Systemic Inflammation: Why "gaps" in your intestinal lining might be the culprit behind your brain fog and mood swings.
• The Recovery Protocol: From chicory root and "mother" kombucha to the surprising benefits of cold, cooked potatoes.

Tim might still be a skeptic, but after seeing his Candida levels, he’s officially on a 60-day fermented food protocol. Join us for a science-heavy (but humor-filled) look at how to rebuild your internal ecosystem from the ground up.
