t starts with one of the most common questions Srdjan gets at the gym: "What should I weigh?" A client asked it that very morning — wanting one number, for her height, that would mean she was healthy. But that number doesn't exist, and chasing it might be the thing holding people back. Healthy weight isn't a point on a scale; it's a range where your body functions, recovers, and performs well.

From there, Pete and Srdjan take apart the whole toolkit we've been handed. The bathroom scale tells you nothing about muscle, metabolism, or health — two people at the same weight can be worlds apart inside, which is how "skinny fat" happens. BMI is worse: Pete traces its strange pedigree from a Belgian astronomer named Adolphe Quetelet, who built it in the 1830s to describe the statistical "average man" and explicitly warned against using it on individuals, to physiologist Ancel Keys, who rebranded it as the Body Mass Index in 1972 after studying white European and American men. It stuck because insurance companies wanted to predict how likely you are to die. The conversation moves into what Srdjan does measure instead — muscle mass — and why the body fat percentages you see on social media are a temporary, miserable, peak-week illusion that even competitors can't hold onto year-round.

A genuinely healthy, strong person looks kind of normal. You'll know it by how you feel — energy, strength, good labs, the ability to get out of a chair unassisted at 80 — not by whether your abs show in July. And because a body that's causing you stress and anxiety isn't actually healthy, the real goal is feeling good physically and mentally, without the extremes. Build muscle, stop measuring the wrong things, and throw the scale away.

KEY TAKEAWAYS

• Healthy weight is a range, not a number. It's where your body functions well — balanced muscle and body fat, stable energy, good recovery, healthy labs.
• The scale measures the least useful thing. It can't see muscle, metabolism, or visceral fat. "Skinny fat" — thin on the outside, metabolically unhealthy on the inside — is the proof.
• BMI has a questionable pedigree. Built by an astronomer for population statistics, never meant for individuals, popularized by insurers tracking mortality. It can't tell muscle from fat, which is why Srdjan himself gets classified as "obese."
• Muscle mass is the number to watch. More muscle speeds metabolism, lowers body fat (including visceral fat), and regulates nearly everything. And it declines with age, so building it early matters.
• Focus on what you're gaining, not losing. Reframing from "I need to lose weight" to "I need to build muscle" is what actually produces fat loss — and it sticks.
• Single-digit body fat is a peak-week illusion. Those shredded photos are taken right after a competition; even competitors can't maintain it. Around 20% body fat can be perfectly healthy with good muscle mass.
• Health is psychological too. If a target weight or body fat is causing stress and anxiety, that's a sign it's the wrong target.
• The stuff that matters doesn't photograph. Joint health, mobility, getting out of a chair at 80 — none of it shows up in a Speedo shot, and all of it matters more.
