I have a 4-year degree in Nutrition Sciences (equivalent to being a dietitian in the US) and I can honestly say that Jeff's videos have taught me more about the practicality of that science than my degree. What you do is a public service. Thank you so much

A doctor, professional bodybuilder, and a trainer?!? This dude is badass

This is something where listening to it once is not enough. Grab a pen a paper take notes and listen to over and over again. Thank you Jeff always enjoy these deep dives!

18:31 go for a slower rate of weight loss, smaller deficit. Body responds better in terms of metabolic rate, hormones and loss of lean tissue. Refeeds and diet breaks are also an option. ***1:01:00 slow rate of weight loss plus go to maintenance every fourth week 21:45 sustainable weight loss 27:30 cardio not the answer while cutting 30:00 lose around 1% of weight a week 52:00 time to heal metabolic damage 58:20 harder if you don’t give time in between cuts

Screw Netflix, here you have a documentary. Jeff, maybe you should start doing documentaries? Maybe hire a crew.

Possibly the best information on weight loss I've ever seen. Nice work fellas.

Oh man, long Jeff Nippard diet video. Time to grab some extra butter popcorn and learn how to be healthy

52:50 I can relate to this! Took me 12 months to get my menstrual cycle back to normal! This was due to PROLONGED low calorie diets! I am now eating wey more, lifting more & finally getting lean but in a healthy and sustainable way with a fully functioning cycle 👍👍🎊🎉🎊🎉💗💗

I‘m normally in bed by ten, even on a weekend. Decided to delay that for once in order to listen to the interview. It’s 11:15pm now but it was totally worth it. Very informative and enjoyable at the same time. The chemistry between the two of you was so good. I hope Eric will be back on your podcast at some point. Thanks, Jeff!

Thanks for this Jeff. I love that you have real academics on here to get through the NOISE on social media. We need to be prioritizing “evidence-based” thinking in all fields but especially in fitness. Ideally it happens when scholars and real practitioners come together.

Great topic! Often get asked about metabolic slowdown and related issues, both online and with clients. Can't wait to see you guys go through this in such detail!

Absolutely the best, most informative content I have ever viewed on YouTube – thank you both!💪🏼

Been following you for a while, and honestly, you are amazing! Such in depth analysis, such inspiration to find out myself, so articulate, professional and respectful and honestly a very friendly aura that you can't help but be drawn too! Thanks for your work!

I LOVE these long discussion style videos, such great content. Keep it up Jeff!

Thank you for having this as a podcast! I started the video to my dog looking at me with her “can we go for a walk eyes” and thought to myself “i wish this was a podcast” just in time for you to mention that it is in fact one! New to your channel and super excited to watch and listen to more of your content!

Thank you so much for taking the time to provide this type of information to us.. and for free! It’s much appreciated and it helps me expand my knowledge. Your videos are awesome Jeff 👏🏽

This was so monumentally helpful for me Jeff. I’m stuck at 150 pounds and I think I may just be lacking sleep and too much cortisol, stress. I’ll look into the thoughts provided here. Thank you fellas.
