Below is a great series of three videos produced by Layne Norton on the topic of Metabolic Damage.
Layne has been at the forefront of the movement in the fitness industry bringing the issue of Metabolic Damage, or as he prefers to call it, Metabolic Adaptation, to public awareness.
Although the validity of the concept of Metabolic Damage is amazingly still meeting with resistance from some corners, more and more people are becoming aware of it and benefiting from it to lose body fat in a healthy and sustainable manner. Nowhere is this more evident than among fitness athletes.
In this first BioLayne Video Log below, Layne introduces Metabolic Damage – what it is, how it occurs, how you can prevent it, and how you can recover from it if it’s already happened to you.
In the next BioLayne Video Log, entitled Metabolic Control, Layne describes what drove him to do the first Metabolic Damage Video Log, what the response has been, and more information about how to recover and improve your metabolic capacity.
In the third installment of the BioLayne Video Log series on Metabolic Damage, this one entitled Damage Control, Layne dives into some of the responses to the first two videos. As he describes, the level of blow-back from coaches guilty of perpetuating starvation diets and endless hours of cardio was significant.
Here Layne addresses the ‘Damage Control’ that these people are trying to implement to save face.
He also talks about specific research on the metabolic adaptations to low calorie/excessive exercise, including a review paper from the University of Colorado entitled Biology’s response to dieting: the impetus for weight regain, published in the American Journal of Physiology. Layne describes this report as the best piece of literature he’s ever read on the subject.
He also specifically covers many of the adaptations that occur due to the “energy gap” created by low calorie/excessive exercise, and how they can set you up for massive metabolic slow-down and weight regain when dieting is done improperly.
