Summary

Weight loss has become a race to get smaller, even when the body is clearly breaking down in the process. The surprise is that a lot of people lose weight and end up more fatigued, under muscled, and metabolically worse off than when they started. We dive deeper into this topic in the latest Habits & Hustle episode with Ashley Koff. We also chat about why GLP-1s make people skinny but not necessarily healthy, why weight often comes back after stopping GLP-1s, and why not eating enough while on these medications is one of the biggest mistakes people make. Ashley Koff, RD is a registered dietitian, founder of The Better Nutrition Program, and a clinician with over 25 years of experience in personalized nutrition. She is the USA Today bestselling author of Your Best Shot (HarperOne) and founder of The Better Nutrition Program (BNP), and has been recognized as one of CNN’s Top 100 Health Makers. What We Discuss: (00:00) Why weight loss has become the wrong goal and how “thinner” replaced healthier(03:12) GLP-1s explained and why they make people skinny without making them healthy(07:08) The real issue with GLP-1s and why misuse creates rebound weight gain(12:41) What actually happens when appetite returns after stopping GLP-1s(17:56) Why not eating enough on GLP-1s leads to muscle loss and metabolic slowdown(22:38) Food noise, hormones, and why appetite is not a willpower problem(34:27) The biggest “just eat less” lie and how it backfires long term(40:03) Fasting, under-fueling, and why trendy restriction worsens outcomes for some people Thank you to our sponsors: Prolon: Get 30% off sitewide plus a $40 bonus gift when you subscribe to their 5-Day Program!

0:00.0	Hi guys, it's Tony Robbins. You're listening to Habits and Hustle. Crush it.
0:06.8	In this episode of Habits and Hustle, I sit down with dietician, author, and friend of mine, Ashley Koff,
0:13.7	to unpack why weight loss has quietly become the wrong goal for so many people and how chasing
0:19.6	thinner without addressing health is leading to
0:22.5	burnout and a rebound weight gain. This conversation cuts through the hype and focuses on what
0:27.8	actually holds up once the shortcut stops working. We break down why GLP-1s don't automatically make you
0:35.3	healthy, how the real problem isn't the medication, but how people
0:39.2	are using it, and why not eating on these medications is a major mistake.
0:50.2	Okay, guys, we have, my friend is back. My friend's back in town.
0:54.8	Her name is Ashley Koff.
0:56.2	She is a dietitian, but she's not just any dietitian.
0:59.1	She's probably one of the smartest dietitians I've ever met.
1:02.3	And anybody who knows you, her, would agree, seriously.

1:09.3	And she has a new book coming.
1:10.6	Actually, her new book is out

1:24.4	comment? And then we're going to take these magic mind shots. If you walk around L.A. or anywhere at this point, everyone is thin now. It's like, I feel like, is it just the fact that we're living in a pseudo reality? But like everybody, I feel, is on one form or another of a GLP one. Have you not noticed this? You know, it was really interesting. The person I had coffee with this
1:44.3	morning said the same thing, and she's in a different job. She's 70, and she was like, all my
1:48.0	60-year-old and seven-year-old friends. It was skinny. But it's funny, like, because some of them
1:52.9	are so happy because they are actually healthy, and some of them are skinny and unhealthy or
