Why Weight Cutting May Be Killing Boxers

JRE MMA Show #181 with Justin Gaethje & Trevor Wittman · Jun 20, 2026 Health & Fitness

Almost every boxing death in the last 10–15 years happens after round 9, often to fighters who are winning and not taking much damage. Wittman believes chronically dehydrating the brain through extreme weight cuts may be cracking the brain like dried lips, creating lethal vulnerability late in fights.

Rogan raises the question of whether Topuria will stay at 155 or go back down to featherweight, noting that Topuria is a smaller body while Gaethje is considerably larger. Gaethje reveals he was 183 in the Paddy fight and 184 lbs going to bed the night before the title fight, waking at 176 — that's how much water the body sheds overnight after a cut. Wittman raises the coaching concern: for fighters who struggle to make weight, the risk of being dropped by a jab from a dehydrated brain is terrifyingly real. Rogan asks whether more weight classes are needed. Gaethje, as an athlete, says he wants nothing changed — grown men and women make their own choices. Wittman is more measured, suggesting weight measurement could move earlier in the week to allow proper recovery, rather than the current same-day or next-day weigh-ins.

The Worry Time Technique

The Only 12 Lessons Buried In Every Self-Help Book - Spence… · Oct 10, 2026 Health & Fitness

The worry-time technique assigns all worries to one scheduled slot (e.g. 5 PM). Every time a worry surfaces, you write it down and ban yourself from engaging with it until that time. When 5 PM arrives, most worries feel trivial and the act of batch-worrying exposes how little it actually accomplishes.

Glad You Did It Activities vs. Mindless Scrolling

The Only 12 Lessons Buried In Every Self-Help Book - Spence… · Oct 10, 2026 Health & Fitness

Most downtime defaults are things you regret immediately after — phone scrolling, binge TV. 'Glad you did it' activities meet the same need for rest but leave you feeling like you spent your time well. The switch from a bad screen to a documentary, a book, or a walk costs almost no extra effort but compounds into identity over time.

Cognitive Restructuring: Training Your Second Thought

The Only 12 Lessons Buried In Every Self-Help Book - Spence… · Oct 10, 2026 Health & Fitness

You rarely control your first reactive thought. But you can train your second thought — the response to the trigger — by asking whether your initial reaction is the most helpful one and replacing it with something equally true but more constructive. Over time, that second thought becomes automatic.
