Comment on How exactly does one eat 1500 calories a day?
Valmond@lemmy.world 2 months agoYour body probably will go full panic mode and store back as much as possible as soon as you starts to eat normally again. I’d advice agains doing anything so violent, and just lower your food intake to a bit under normal.

Store back what? That’s not how physics works. If they continue to eat only what their body needs to maintain a set weight, they’re not magically going to gain weight because their body somehow is able to violate the laws of physics.

So first off, I don’t think you should bring the laws of physics into conversations of how human bodies store fat. I know it’s tempting - I’ve been there before - but it’s just too reductive to be useful in the conversation, and it leads to generally poor conclusions.
While it’s true that energy cannot be ‘conjured from nothing’ - human bodies don’t quite work on a fixed energy in/out model. They can be variably efficient in how much energy is required to perform certain tasks, and secondary systems can be turned off when the need to conserve energy becomes apparent (leptin is the signaling mechanism for this).
The main mechanisms that cause rebound weight gain after sharp dieting is a reduction in passive energy needs stemming from the change in leptin levels, along with leptins very strong effect on appetite.
I suggest to you, and anyone still under the impression that CICO is a useful model for understanding human metabolism, to read the book The Hungry Brain. It’s hugely useful for gaining greater insight into the subject.

Are you suggesting our bodies are more efficient and break thermodynamics?
What secondary systems get turned off? You’re body is going to utilize energy anyway it can if it needs it, if it doesn’t it stores it, usually in the form of fat.
No it’s from eating way more calories…this is literally junk science your parroting here. The rebound in weight is because someone decides to stuff themselves again.
That book is about the psychology of overeating.
Hell here is a quote from his AMA:

It’s callef the yoyo effect (that’s why you should see a nutritionist when you want to lose weight). Also recent research hints at cells becoming more efficient when there is less energy available. There is even a Kurzhesagt video about it if you are interested.
It seems it is not so easy as calories in, calories out.
SupraMario@lemmy.world 2 months ago
No…just no. You’re arguing against literal physical laws here. Most people do not accurately count their calories and end up posting antidotal garbage that gets passed off as science.
Valmond@lemmy.world 2 months ago
Dude, cells are not using up 100% of the energy you ingest, if they did you could live off a sugar cube a year. I think it might be you that doesn’t understand how the laws of physics work lol.

Did you miss the “when you start eating normally again” bit?
You can rant all you want about the laws of physics, but you might want to practice your reading comprehension.
SupraMario@lemmy.world 2 months ago
Then you’re not eating normally… you’re eating more than you need.
theluckyone@lemmy.world 2 months ago
Most people don’t count calories. You said it yourself, a few posts below. Are you going to start redefining “normal” now to meet your argument?
