Get your free custom nutrition plan (exclusive to podcast listeners) when you join Wits & Weights Physique University for just $27/month -- There was a day when everything we thought we knew about losing weight got turned upside down. For decades, the advice was simple: eat less, move more. But then scientists started asking why weight loss always seemed to get harder over time, and what they discovered changed everything. This landmark Episode 350 explores the paradigm shift that revolutionized our understanding of metabolism, fat loss, and why 95% of people regain lost weight. Main Takeaways: Your body doesn't just passively lose weight, it actively fights back by slowing metabolism and increasing hunger within 2-3 weeks of dieting The shift from moral food judgments to flexible, data-driven nutrition revolutionized sustainable fat loss Three game-changing strategies emerged: macro tracking as a foundation, working with (not against) metabolic adaptation, and strength training as metabolic insurance This scientific revolution changed how we view our bodies, from broken machines needing punishment to intelligent adaptive systems responding to our lifestyle signals Episode Mentioned: Fat Loss vs. Weight Loss Timestamps: 0:01 - The day everything changed about weight loss 4:30 - Why the "eat less, move more" approach failed 8:47 - How your body fights back: the hormone cascade 10:47 - The rise of flexible dieting and evidence-based coaching 12:29 - Key people who changed the game 14:37 - From food restriction to food awareness 19:35 - 3 game-changing strategies from the research Support the show 🎓 Lose fat for good in Physique University, now just $27/mo ( tap here and I’ll create a FREE custom nutrition plan when you join ) 👥 Join our Facebook community for Q&As & support 👋 Ask a question or find me on Instagram 📱 Try MacroFactor 2 weeks free with code WITSANDWEIGHTS (my favorite nutrition app)…

Be Careful With Fake Zoom Client Downloads
Miscreants are tricking victims into downloading fake Zoom clients (and likely other meeting software) by first sending them fake meeting invites that direct victims to a page that offers malware for download as an update to the Zoom client.

Python tarfile Vulnerability
Recently, the Python tarfile module introduced a filter option to help mitigate some of the insecure behavior common to software unpacking archives. This filter is, however, not working quite as well as it should.
