The more food you eat, the more micronutrients you take in
This doesn’t seem like the ideal way of optimizing your micronutrient consumption.
Plus, you get to eat more ice cream.
I’m not sure that makes much of a difference. To illustrate, consider a strapping young man who can eat a pint of ice cream a day and stay in energy balance. Compare him with a petite girl who can only eat half a pint a day of ice cream and stay in balance. Does the man derive significantly more pleasure in life from ice cream eating than the girl? I doubt it.
If you previously damaged your metabolism
Well how would you define “damaged” and what does it mean?
I mean, if you’re using it wrong, sure
No need for a semantic debate, what’s commonly referred to as “starvation mode,” which I have referred to as “running cool,” is perfectly normal and healthy in my non-professional opinion.
This doesn’t seem like the ideal way of optimizing your micronutrient consumption.
Perhaps not. Supplementation seems like an easy solution, but it’s been shown multiple times that you get more benefit from micronutrients from food vs micronutrients from supplementation.
I’m not sure that makes much of a difference.
If you don’t care about more ice cream, then FINE. More for me.
Well how would you define “damaged” and what does it mean?
Layne Norton has a few goodvideos on the subject. “Damage” refers to the metabolism being downregulated to the point that a person can eat very low calories, do tons of exercise, and still not lose weight/fat.

I know it’s a pointless crusade, but I really dislike terms being misused. Starvation is a very real thing, and when the word is misused, it conflates “Starvation causing muscle/organ loss” with “Metabolism is downregulated,” You absolutely need to avoid going into starvation, but downregulating metabolism is an inevitable effect of losing weight.
Perhaps not. Supplementation seems like an easy solution, but it’s been shown multiple times that you get more benefit from micronutrients from food vs micronutrients from supplementation.
The more obvious solution is to tweak your consumption of foods which contain lots of micronutrients compared to their calorie content. i.e. eat your vegetables.
If you don’t care about more ice cream, then FINE. More for me.
What I care about is eating satisfaction. It’s not obvious to me that more ice cream necessarily means more eating satisfaction.
“Damage” refers to the metabolism being downregulated to the point that a person can eat very low calories, do tons of exercise, and still not lose weight/fat.
I would call that “running cool” and in my non-professional opinion, it’s perfectly normal and healthy. And if such a person wants to lose further fat, they need only reduce their calorie intake further. By the way, I started listening to the video, and I simply don’t believe that a person can do 2-3 hours a day of cardio, eat 800 to 1000 calories a day, and not lose weight. I think any person who makes such a claim is lying about his food intake.
I know it’s a pointless crusade, but I really dislike terms being misused
Fine, but if you have a semantic nitpick I think it’s good practice to label it as such. Here’s what I said at the beginning:
People sometimes refer to the cooler situation as “starvation mode,” but I think this is an overstatement.

Layne is a PhD in nutrition science, record holding powerlifter/bodybuilder, and renowned coach. So he has academic credentials, personal success, and has successfully helped others. There are very few people in nutrition that you can generally trust, and he’s one of them. So when he says something, it’s generally OK to accept it on face value.
Fine, but if you have a semantic nitpick I think it’s good practice to label it as such
Fair point. I’ll do that from now on. “Starvation mode” is just one of those phrases that trigger an immediate “No, you’re using that word wrong, stop it!!” reactions (and yes, I know about prescriptivism vs descriptivism, but I’m not a linguist, and I have an interest in phrasing having consistent meanings!)

It’s a bit of a cliche, but extraordinary claims require extraordinary proof. The claim that someone can do 2-3 hours of cardio a day; eat only 800 to 1000 calories, and not lose weight is extraordinary. To back up a claim like that, you would need to do a study where the subject was carefully monitored with doubly labeled water or confined to a live-in laboratory.
Did he personally monitor these people he is describing?
Most of the people that get to that level are bodybuilding competitors. If the population weren’t specified, I’d agree with your suspicion, since it is pretty well demonstrated that most weight loss issues are related to inaccurate food reporting/consumption. However, folks that are serious about bodybuilding are pretty meticulous about following diet plans, and aren’t strangers to hard work, denying physical urges, and doing really uncomfortable stuff for their sport. I’d agree that a typical obese person is almost certainly just underreporting their calorie intake.
There is no metabolic ward evidence for this, if that’s the standard you’re after. Layne hasn’t had anyone do this sort of routine because he thinks its incredibly harmful for long term success in bodybuilding, so he hasn’t personally seen this. However, he has coached those whose prior coaches did this, and he worked to repair the metabolism.
Respectfully, that’s not even strong evidence, let alone extraordinary evidence. It’s just hearsay.
I would be willing to bet serious money that any healthy adult, carefully monitored, who did 2-3 hours of cardio a day and ate only 800 to 1000 calories would either lose weight or (far more likely) end the experiment because because he literally felt like he was starving to death.
By the way, I was reading the other day about a study where professional nutritionists were assessed to see how well they reported their calories. And they under-reported significantly.
shrug Metabolic damage is a real problem in the bodybuilding community. I don’t have any stock in the exact numbers being there; 800 calories and 3 hours of cardio per day is not much worse than 1200 calories and 1 hour of cardio per day. Both indicate a depressed metabolism and an inefficient (if not counterproductive) weight management strategy.
I’d agree that 800 calories and 3 hours of cardio per day and constant weight is extremely unlikely hypothesis vs. misrepresenting food intake or activity level. I don’t think it’s impossible that a person can adapt themselves to that. Some coaches prescribe this caloric intake and activity level.
To see how plausible it was, I hypothesized a 25 year old 5′2″ 120lb female aspiring bodybuilder at around 11%BF. This RMR calculator puts the basic metabolism at 1,200-1,500 calories per day. 2-3 hours of low impact aerobics gives 662-993 calories according to this calculator. Assuming cardio is done 5 times per week, this is an average of either 1,670-1,972(2 hours cardio) or 1,900-2,200 (3 hours cardio) calories calculated to maintain weight.
The most extreme situation (2,200 calorie maintenance and 800 calories eaten = 1,400 calorie deficit) seems obviously impossible. The other bound (1,670 calorie − 800 calories eating = 870 calorie deficit) seems more possible to me. I’ve personally had my maintenance calorie intake down to about 1,500 (and i was meticulously measuring everything), which is ~700 calories less than calculators would have predicted given my activity level.
And they under-reported significantly.
Not surprised. Virtually everyone underreports (unless they’re chronically underweight, and then they overreport). That’s why I included the bit about Layne’s personal success (ie what he does really works for himself) and coaching success (ie what he says works for his clients). He practices what he preaches, and his results speak for his methods.
Metabolic damage is a real problem in the bodybuilding community.
Why is it a problem to “run cool” as I have described it? (ETA: Other than what you said above)
By the way, since you disapprove of the misuse of language, I would ask that you demonstrate actual harm from what you describe as “metabolic damage” or use a less loaded phrase.
ETA: I understand that someone who is “running cool” will get less micronutrients, all else being equal, than someone who is not. I also understand that someone who is “running cool” will get to eat less ice cream than someone who is not.
But I don’t see how any reasonable person could see these things as harm. First of all, as someone else alluded to, there is no a priori reason to think that more micronutrients is better. Second, even if more micronutrients is better, it’s easy enough to get micronutrients from foods which are low in calories. Third, having to eat a bit less ice cream does not seem harmful to me.
In short, I think you are misusing the word “damage.”
The other bound (1,670 calorie − 800 calories eating = 870 calorie deficit) seems more possible to me.
I would be willing to bet serious money that any 25 year old 5′2″ 120 pound female aspiring body builder who burns 600-900 calories a day doing low impact aerobics and who eats in the 800-1000 calorie range will not be 120 pounds for very long.
Virtually everyone underreports
Yes, even bodybuilding competitors. As well as anyone who claims to be unable to lose weight through calorie restriction.
Why is it a problem to “run cool” as I have described it?
It’s not. It’s a natural adaptation to a caloric deficit. If you think that’s what I’m arguing, then we’ve got a pretty big misunderstanding.
To make sure we’re talking about the same things, I’d like to clarify my understanding of “running cool.” You say that a person’s average calorie intake per day for weight maintenance is (for example) 2000 calories. If you eat 1900 calories for a week, you won’t lose the 1/5th of a pound you’d expect. Your metabolism might shift down to about 1950 per day, and you’d only lose 1/10th of a pound. Likewise, if you eat 2100 calories for a week, you won’t gain 1/5th of a pound. You’d fidget more, put off more body heat, etc and maybe gain 1/10th of a pound. Is that about right?
The extension that I’d make is that eventually the body completely adapts to the new calorie level, such that 1900 calories no longer results in any weight loss at all. It’s the new maintenance point. This is the downregulation I am talking about.
If our hypothetical-person started with a 500 calorie deficit, they’d likely get about 450 calories per day of weight loss and 50 calories of metabolic downregulation, or running cool. Eventually, 1,500 calories a day becomes the maintenance point, and you have to eat less food to continue to lose weight.
I would ask that you demonstrate actual harm from what you describe as “metabolic damage” or use a less loaded phrase.
Did you watch the videos or just turn them off after the extraordinary claim? The videos pretty clearly explain what happens to cause this situation. It’s not like a person would start off eating 800 calories, 2 hours of cardio, and not lose weight. The situation develops over a great deal of time. A person would start off with 2,000 calorie maintenance, and then eat 1,800 calories to lose weight. Eventually, fat loss stalls, and calorie intake has to go down to 1,600. Eventually, that stalls, and calories have to go down again. This repeats until you’re at a very low calorie intake level, such that the only way you can lose weight is by going into the actual starvation mode.
Does that sound good to you? I can see the benefit from an evolutionary standpoint to have the ability to survive that sort of intake with that energy output. But it isn’t something I’d want for myself, and it’s counterproductive to the goal of ‘losing fat’.
Fine, then please stop referring to it as “damage.” It’s not damage, it’s a perfectly normal and healthy way to live and it’s probably healthier than running hot.
The extension that I’d make is that eventually the body completely adapts to the new calorie level, such that 1900 calories no longer results in any weight loss at all. It’s the new maintenance point. This is the downregulation I am talking about.
That may very well be true.

Turned them off.

I don’t believe this either. While there may exist some people with bona fide health problems whose bodies break down muscle and organs instead of fat deposits, as far as I know that’s extremely rare. Also I am extremely skeptical that calorie deprivation could cause such a problem.
Anyway, the bottom line is that you have failed to point demonstrate any actual harm in people with “damaged” metabolisms. So please stop misusing the word “damage”
Fine, then please stop referring to it as “damage.” It’s not damage, it’s a perfectly normal and healthy way to live and it’s probably healthier than running hot.
Sigh. Again, “running cool” is not “metabolic damage.” I’m not going to explain it again, as you’ve demonstrated an unwillingness to listen and consider what I’m saying or looking at the links I’ve provided.
Yes it is, using your own definition. And you have failed to demonstrate any actual harm which comes from “metabolic damage” So please stop misusing the word “damage”
I’m not going to explain it again, as you’ve demonstrated an unwillingness to listen and consider what I’m saying or looking at the links I’ve provided.
Nonsense, I’ve considered your argument carefully. As far as the links go, it’s not my responsibility to wade through an hour’s worth of youtube videos looking for evidence supporting or explanations of your point.
The fact is that you’ve made a couple extraordinary claims and you refuse to provide strong evidence, let alone extraordinary evidence to support those claims. You insist on misusing the word “damage” even while professing a distaste for the misuse of words. The problem isn’t my unwillingness to consider your point; the problem is your unwillingness to consider the flaws in your own point.
This doesn’t seem like the ideal way of optimizing your micronutrient consumption.
I’m not sure that makes much of a difference. To illustrate, consider a strapping young man who can eat a pint of ice cream a day and stay in energy balance.

Bodybuilding competitors generally don’t do much cardio (aka long-duration low-intensity workouts), as far as I know, not 2-3 hours a day.
That’s not much evidence, it’s basically “my old coach starved me and my BF% didn’t go down enough” kinda thing...
