Not sure if this is clear. Our bodies are supposed to replace all the cells every 7 or so years. Does that mean the fat too? Or when someone loses 20 year weight, are you getting rid of 20 year old fat?

The 7 year thing is a myth. Howtown has a very good summary on it. 7 year myth some cells are replaced but how often depends on the cell type, some never get replaced.
When you gain weight your fat cells grow, and when you lose weight they shrink. You don’t actually gain and lose fat cells the way people think. However, the stuff in those cells could very well be old. It’s a complex system and hard to sum up and I’m only friends with the biology people from college but that’s what I understand from them.
But as my doctor explained to me, if they get big enough, they divide. Then even if you lose weight, you have fat cells hanging around who think they should be holding onto more fat than they are. So your body will want to be fat, and will enforce that with cravings.
It’s why it’s extremely hard to lose a large amount of weight and leave it off. I’m on my third major attempt now.
Seems like that would be an argument for liposuction as a way to supplement other weight loss because it would remove those cells.
I’ve had the same thought. Haven’t really looked into it though.
I’ve studied nutrition science and we talked about what you described and yes, the blunt “truth” is that liposuction is the only reliable way to really get rid of “emptied fat cells”. There are a lot of things playing into the dreaded yo yo effect but the fact that it is much easier to refill emptied cells than to make new cells via division is definitely a big factor.
(“Truth” is in “” because I dislike this term in a scientific context but english is my third language and it’s pretty late over here so I am struggling to find a better suited word)
Good luck on your weight loss journey. It is an incredibly hard and brave one to take and I admire that you are trying.
I don’t know much about liposuction but I believe it can only be done on subcutaneous fat (just under the skin) but not the deeper intra-abdominal fat that can be the cause of fat related health problems. If you can ‘pinch’ most of your fat then it is probably subcutaneous and lipo would help to remove the excess cells.
It absolutely is. But I’m pretty sure it’s expensive
And of course health insurance wouldn’t cover it because it’s “elective”.
The weight set point theory doesn’t apply to low carbohydrate eating. The abundance of fat cells does not make people doing keto fatter. It’s mostly the carbohydrate insulin model of obesity. Eating food that drives insulin makes people gain weight.
The abundance of active adipocytes can drive leptin issues, and aromatase issues. But as those adipocytes get emptied, there are no longer being as metabolically active and aren’t an issue. Especially on low carbohydrate diets that don’t drive elevated insulin levels
I’ve heard similar, that your body wants to keep the “norm” whatever that is. And it makes sense that any extreme weight loss, would seem, to your body, that there is a famine or something is wrong and then reset the balance back to what it was, as soon as it can.
Set point isn’t some magic thing, it’s just the fact that if you eat a consistent diet, you’ll gain/lose weight until your calories in is the same as your calories out. If you’re overweight, you’re eating more than the human body evolved to handle, so your stomach has to expand to accommodate that. When you try and lose weight, you’re usually eating less food, and so your stomach isn’t full and can cause discomfort.
Losing weight is hard, I get it. I’m working on it myself. But it’s not like your body is working against you. If perceived famine caused people to gain weight, victims of actual famines would be overweight, not skin and bones. It’s not your body against you, it’s the impulsive parts of your brain versus the rational parts.
your taste bud’s cravings are the the fault of America’s food culture, not your body
Can you cite a reputable source to confirm this? Doesn’t seem right to me.
i mean, it’s anecdotal, but I crave things that are super unhealthy, like Rally’s fries or ice cream, and I rarely used to crave anything that has real nutritional value. Now that I’ve cut back quite a bit on those, my cravings are starting to return to more healthy options, and right now I would kill for some roasted zucchini.
in my experience, people are more likely to crave fast food and sweets because they’re literally designed to be addictive. if most people follow their cravings, they aren’t going for the things that provide nutritional benefits, they’re going for the tasty stuff
¿Por qué no los dos?
That opens the door to new insults such as “You so fat your fat cells are the size of grapes”
So, losing weight, is like taking a long needed shower for your cells.
Edit: That link is awesome. Your gut lining turns over every few days and your skin is weeks? That brings up so many more questions about the biome then.
Kind of? The cells, called adipocytes, primarily store triglycerides and a few other things in a liquid form. When you lose weight that liquid gets squeezed out and used as energy, to build other chemicals your body needs, or peed straight out.
So less a shower and more getting rung out like a sponge.
Most of the weight is carbon that is breathed out actually, but metabolic water isn’t insignificant.
My brain has to readjust to all this, very strange.
