I searched all 42 pages and saw no mention of this so I figured I would ask. Dr. Layne Norton did some research on metabolic adaptation in 2014. This to me, set the ground work for his new ideal of reverse dieting. Is there any merit in you all’s opinion or the literature that verifies this? If there is rebuttal could you point me in the right direction for studies to read up on?
maybe im reading the research wrong but to my understanding from this is that the body adapts to the weight loss, as the mitochondria become more efficient. I understand that this study also seemed to be centered around physique competitors, and concludes by acknowledging that the need for further research into reverse dieting needs to be conducted. Reverse dieting has been all I’ve heard on the tubes from Dr. Layne Norton, your thoughts?
That paper is an opinion piece, not research. The opinions have not been substantiated by controlled trials or even retrospective studies. Also, notice the 3rd author.
I do not disagree with Layne about much, but the metabolic damage stuff is a bit too much “woo” for me.
Im going to be honest Doc you have to put more info out haha! In today’s fitness world…or heck even health industry as a whole it is difficult to sort through what to listen to and what not to.
What I have gathered from looking into dieting myself is that obviously the more weight you lose the harder it is going to be. Further, that we as adaptive as we are, are also pretty resilient to a lot of things so having a permanently damaged metabolism seems hard to believe. I have been personally messing around with macros after reading your articles on the website. I personally learned today that sometimes having to little of carbohydrates can be detrimental. I (SEMI) accidentally went sub -100g carbs yesterday for my daily (hit fats and protein) I work out in the mornings because its the only time I can. So went to do dead-lifts 8x8 RPE6ish and felt the repercussions for my choices.
A follow up question to keep this thread going a little longer. What would you say is the maximum amount of carbohydrate restriction before performance is impacted? Obviously sub 100g is way above that for me and im assuming it would vary based on person.
Yes I agree that losing weight and keeping it off is difficult, though not necessarily losing more weight and keeping it off (see National Weight Loss Control Registry).
I don’t think there is a single carbohydrate level that will, reliably, alter performance without context.
