OB is an online fat loss coach, the founder of OB Health Coaching, and host of the OB Health Podcast.

What if the biggest obstacle to losing weight isn't food, but your relationship with it? OB spent eight years trapped in an all-or-nothing relationship with food that tanked his hormones, before rebuilding his entire coaching philosophy around fixing it instead of restricting harder. So why do 95% of people who lose weight gain it back within five years, and what does a genuinely healthy relationship with food actually look like?

Expect to learn why chasing the next new fitness trend is really just shiny object syndrome, why 95% of people who lose weight gain it back within five years, how to rebuild a broken relationship with food by adding things in instead of taking them away, why fiber — not probiotics — is the real lever for gut health, the three-second test for whether your fish oil has gone rancid, why sleep trackers get your actual sleep data wrong roughly half the time, and why men and women should be training in the gym exactly the same way and much more…

Judy Grisel is a professor of psychology and neuroscience at Bucknell University and the author of Never Enough: The Neuroscience and Experience of Addiction.

What actually drives addiction — genes or environment? Judy spent a decade lost to addiction, homeless and sick, before turning her own life into a research question and becoming one of the field's leading addiction neuroscientists. Her answer is close to fifty-fifty. So what tips the balance, and why do addiction rates keep climbing even though our genes haven't changed?

Expect to learn why cannabis may be more addictive than heroin, what's actually happening in the brain's dopamine pathway when we crave something, why the anticipation of a reward feels better than the reward itself, why 90% of people who develop an addiction start using before they turn 18, how boredom is a bigger risk factor than poverty, how Judy went from homeless and addicted to a tenured neuroscientist, why "resetting your dopamine" isn't as simple as people claim online and much more…

Nick Pelletier is an ultra endurance athlete, documentary filmmaker, and host of the Comfort Breeds Complacency podcast.

What does it take to fail at something twice and still go back? Nick spent four years and three attempts trying to swim the 113-kilometer length of Okanagan Lake, battling chafing so severe he couldn't lift his arms, wildfire smoke that erased the shoreline, and a shoulder that gave out mid-swim. So what finally got him across, and what happens when Mother Nature says no anyway?

Expect to learn why Nick's first attempt at swimming Okanagan Lake ended in agonizing chafing after eight hours, how wildfire smoke wiped out his ability to sight the shoreline and ended his second attempt, what it felt like when his shoulder gave out from thousands of strokes, why his dad was the one who had to call off two failed attempts, what it's like to get stung by a Portuguese man o' war mid-ocean-swim and lose the use of your legs, why a hot shower turned out to be the real cure for the sting, and how three failures over four years turned into a 71-hour finish and much more…

Ryan Glatt is a brain health coach, certified personal trainer, and director of the FitBrain Program at the Pacific Neuroscience Institute, and author of Brain Health and Exercise.

What's actually happening in your brain when you exercise? Most of what circulates online about neuroplasticity, brain rewiring, and "brain hacks" is either oversimplified or flat-out wrong, and there's no shortage of influencers cashing in on the confusion. So what does the research actually show about exercise and the brain, and how do you build a routine that works with it instead of guessing?

Expect to learn what exergaming actually is and how a Nintendo Wii could help rehab a stroke patient, why neuroplasticity is an ability and not a resource you can buy in a bottle, the myth behind "neurons that wire together, fire together," the three levels at which exercise changes your brain (micro, macro, and behavioral), why he calls exercise a "neuropolypill," how to program aerobic, resistance, and neuromotor training across your week, and why doing the thing you're worst at might be the best thing for your brain and much more…

Mark Divine is a retired U.S. Navy SEAL Commander, founder of SEALFIT and Unbeatable Mind, and author of several bestselling books including Unbeatable Mind and The Way of the SEAL.

What's actually happening when a mind can't be broken? Mark earned the nickname "Cyborg" in the SEALs for barely registering pain, but what he's built since retiring goes far beyond physical toughness into a rigorous daily practice of training the mind itself. So what does it actually take to stop reacting to your own thoughts, and is willpower even the right word for it?

Expect to learn where Mark's nickname "Cyborg" actually came from, how childhood conditioning and years of Zen practice combined to change his relationship with pain, why box breathing became the technique he introduced to the SEALs in 2006, what "catching the snake at the head" means and why it's the key to breaking reactive patterns, how meditation training compounds like physical training but shows no visible reps, why almost none of your opinions are actually your own, and much more…

Dr. Dan Sullivan is a naturopathic doctor, functional medicine practitioner, and ADHD specialist.

What's actually driving the rise in adult ADHD diagnoses? Standard of care jumps straight to stimulant medication, but Dr. Dan Sullivan argues that medicating a body that's never been tested is like bolting a turbocharger onto an engine that was never built to handle it. So what should actually come before the prescription, and why does "normal" bloodwork rarely mean optimal?

Expect to learn why ADHD medication works like a turbocharger on an unprepared engine, why stimulants can make ADHD worse when nutrient deficiencies go unaddressed, why ADHD comes with a genetically delayed circadian rhythm that makes falling asleep harder, what "normal" lab ranges actually hide, why protein and tyrosine in the morning matter more than people think, how to train HRV instead of just tracking it, and much more…

Bradley Schurman is a demographer, futurist, and the author of The Super Age: Decoding Our Demographic Destiny.

What happens when a country runs out of people before it runs out of promises to them? By the end of the decade, America will have more people over 65 than under 18, and the Social Security and Medicare trust funds are on pace to run dry by 2030 with no fix in sight. So how much of that shortfall lands on the generation that didn't create it, and what happens to the cities, jobs, and social contract left behind

Expect to learn why Bradley ranked 250 American cities on their long-term resilience and what it revealed about where people should actually move, why China overbuilt its housing by 65 million units (the entire population of France), why Social Security and Medicare are on track to run out of money by 2030 with zero serious plans to fix it, why demographic decline is quietly rewriting the future of war in Ukraine and beyond, why an aging population might be a parachute rather than a burden, why multi-generational households are quietly making a comeback, and much more…
