For those of you trying to understand weight regain due to low leptin

Very good science lesson @surfnscientist
I loved your talk but you need to remember
it's biology not physics @garytaubes

“Eat less, move more and keep breathing.

Diet & exercise. Amen!”

I write:

Kevin, he does not address the Reduced Obese.

He doesn't know what he doesn't know.

Kevin writes:

“I thought it strange that you posted this link, as indeed,

it does not address the things you espouse.

But again I have to reiterate that, for me personally,

eating less (and eating different), and "moving" more . . . does work.

I will admit that I have been taking a good look at diet,

and some hefty reduction in carbs is attractive.

Maybe even some increased fat.

But as for exercise, I am steadfast on a 6-day per week grueling regimen.

Stubborn Lithuanian, I am.”

I write: Kevin, I like   The mathematics of weight loss by Ruben Meerman for the science of where does the weight loss go? However he does not know why reduced obese regain weight w low cal diet and exercise. Not sure what's hard to understand Kevin? Kevin writes: What??? I never said it was hard for me to understand. And I too loved the video for the science of where the weight loss goes. Very interesting stuff for sure. I was just saying that a grueling regimen of exercise works for me. That is not to say it works for everyone. Maybe I am one in a million, altho I hate to flatter myself. I am probably the exception to the average workout stooge. When I began these workouts many years ago, it was not with the goal to lose weight. It was to gain mass. I drank protein malts (under direction of my ex-body-builder/trainer). I worked out 7 days per week, and then eventually pared down to 6 days. I was committed and focused. To the point where I was reprimanded for coming in late to work because I hadn't finished my workout. I was in my late 40s then and deeply in the throes of the dreaded male menopause. Today, it is still a focus for me but not as accessible. I hate that I am not now going to the gym six days per week. Why the reduced obese regain weight with a low-cal diet and exercise causes me to question both the diet and the level of exercise — not as much the diet as the exercise. But that is just me. I know how apathetic we Americans can be. Unwilling to break an ongoing sweat at the gym once we even get there. It behooves us to bring ourselves to the brink every time we go. A good morning workout will invigorate me for the rest of the day. And the diet, that is another matter entirely. This whole diet and exercise thing needs to be right on our front burners, not simmering somewhere on our back burners. If we were as passionate about our health and well-being as we are about our careers, then there would be less confusion and happier and lengthier retirements. In my opinion, of course.”  - Kevin I write: Kevin I am very glad you responded so we can get into the weeds. Kevin you write : “Why the reduced obese regain weight with a low-cal diet and exercise causes me to question both the diet and the level of exercise — not as much the diet as the exercise.” Kevin this is what I don't understand why you don't believe the science of LOW LEPTIN in the reduced obese. Haven't you read this NYT article yet on the Biggest Loser? Reduced obese have low leptin levels that tells the brain it is starving. Hence EXERCISE METABOLISM is reduced by 40% That means when you walk a mile you don't burn 100 calories you burn 60 calories. Also RESTING METABOLISM is 70% of total metabolism. Exercise does not affect this. Kevin writes “I just read the NYT article. Thanks for the link. I agree with it. It does take a monumental effort to keep weight off . More rigorous exercise will do it for some. Not all. I understand that. And I do believe the science. Here is a good article on the hormone Leptin. I think it does a great job of explaining what you are saying — for laymen like me. https://www.healthline.com/nutrition/leptin-101 But as the NYT article points out, increased levels of exercise can keep weight off. Again, not everyone. And I understand there are those who cannot continue with a serious exercise regimen, whether it be because of injuries, age, time constraints, or the fact that it just isn't working for them. I fail to see the correlation between low Leptin levels and the reduction of exercise metabolism by 40%. Can you better explain that to me? And if you only burn 60 calories by walking a mile, walk two miles. There will always be adjustments that will have to be made to any workout — continuously. Failing to accept that will end in discouragement or even disaster. Dear Kevin, Start with this video 2 min HBO FAT NATION link then see all the things Leptin does below. Kevin writes: So, my question is . . . before America had an obesity epidemic before fast food, did none of these brain problems exist? Is this the result of McDonalds, Wendys, KFC, Hardees, etc? I don't remember a fat nation when I was growing up in the 60s and 70s . Even the 80s. So the obesity problem grew out of junk food and couch potatoism? Sedentary lifestyle? And now our brains have adapted and are telling us we are starving even tho we are reduced obese? Cowabunga!!! God bless corporate America who has been feeding us crap for decades . . . and continues to do so. I write: Not at all Kevin. Famine is what caused this brain wiring. Brain cells die but not fat cells.   Fat cells are needed for survival. Thus low leptin is the anti-starvation hormone and does not allow body weight to get too low when it will be dangerous. Leptin does this by slowing down exercise metabolism and resting metabolism. In other words Leptin makes the body VERY EFFICIENT at using the 800 calorie diet without further weight loss. Then it replaces the fat first before heating up the body.   It wants to get a nice buffer of fat. for a possible famine next week. This is why very lean elderly have higher death. A little pouch of fat prevents mortality during illness.

Kevin

I have met Dr. Rudy Leibel.  Very nice guy. He was co-founder of Leptin

Cheated out of Nobel Prize link

Kevin asks:

and continues to do so.

My response:

Not at all Kevin.

Famine is what caused this brain wiring to survive famines.  

Brain cells die but not fat cells.  

Fat cells are needed for survival.

Thus low leptin is the anti-starvation hormone

and does not allow body weight to get too low when it will be dangerous.

Leptin does this by

slowing down exercise metabolism and resting metabolism.

In other words Leptin makes the body VERY EFFICIENT

at using the 800 calorie diet without further weight loss.

Then it replaces the fat first before heating up the body.  

The body wants to get a nice buffer of fat.

for a possible famine next week.

This is why very lean elderly have higher death.

A little pouch of fat prevents mortality during illness.
