starvation and weight loss

so i do alot of reading online and have seen that if you starve yourself throughout the day and than finally eat at the end of it but not go over your calorie limit your body will think you are going to starve yourself again and hold on to fat because its in fear of starvation i know you cant take everything online for truth so i was wondering if you knew anything about this myth or truth

Myth. How would you explain starvation in impoverished countries where people are walking skeletons? They don't look like they're holding onto fat, do they?0

100% myth0

Myth. Different things can cause your metabolism to slow down some, but not enough to stop weight loss all together. If this was true then no one would ever starve to death.0

Hmmm . . .why do people (including myself) swear by 16:8 fasting then?0

I am genuinely curious about this. I keep seeing here that starvation mode is a myth, yet I too have heard over and over (from many sources, including Weight Watchers) that if you don't eat enough your body will think it is starving and slow your metabolism and hold into fat. Are there scientific articles anyone can post about the starvation mode myth? Am interested in reading more about this.0

Why do you "swear by it"? What does it supposedly do to you?0 -

Maybe because it is easier to create a calorie deficit within a window of eating?

Just google the Minnesota starvation experiment. There has been more research since then, but that's still the most well-known.0 -

I find that it controls my appetite. Much easier for me to stick to a deficit when I'm doing it than when I'm not.

thank you for all the info its my huband that dose this not intentionally but i feared it was not good for him thank you for keeping mu mind at ease0

Eating at a severe deficit over an extended period of time will slow down your BMR. But it does not stop it or cause your body to hold onto fat. Your body still needs energy to operate. It doesn't just switch to solar mode. Starving people do not, in general, have trouble losing weight.0

Your metabolism may slow down a small amount to adjust to a very low calorie diet, but it will not slow enough to prevent weight loss entirely. The main reason you don't want to lower your intake too much is it can cause a faster rate of muscle loss while losing weight, it can cause you to not get enough nutrients (vitamins, minerals, etc), and it can be harder to stick to a diet of you are starving all the time.

This is the real myth. You actually can.0 -
Watch an episode of Naked and Afraid. I've seen people lose up to 40 pounds in their 21 days of their "survival" trip because they are literally starving. I wouldn't recommend going to that extreme, though--those people are nuts. I wouldn't last 2 days.

Yeah, but my point is, it sounds like her husband is basically doing an established regimen and she shouldn't worry about its safety.0 -
it is funny because if you enter too few calories into MFP there is a warning at the bottom that says you are eating too few calories....0

Okay, this is what I have heard before, and people have called it "starvation mode." Semantics, I guess. Below is what I have heard before and I guess this is true.
From Weight Watchers:
Restricting calories during weight loss lowers metabolism because the body becomes more efficient, requiring fewer calories to perform the necessary daily functions for survival. Consequently, this can slow (but not stop) the anticipated rate of weight loss.
For example, if an individual needs 2,000 calories per day to maintain weight, reducing intake to 1,500 calories, assuming exercise stays the same, should provide a 1 pound per week weight loss (Note: 1 pound of weight is equivalent to about 3,500 calories). Furthermore, reducing to 1,000 calories should result in a weight loss of 2 pounds per week and going down to 500 calories a day should result in a weight loss of 3 pounds per week. However, if an individual actually reduces their intake to 500 calories, the weight loss would not likely be a steady 3 pounds per week because of the reduced metabolic rate. It would likely be around 2¼ to 2½ pounds.0 -
The reason people who go long periods durin the day without eating tend not to lose weight or even gain weigh is because by the time you go to eat you are so hungry you over eat, and you are less likely to burn caleries later in the day then you are to eat the calories earlier.0

Yes, the above is true. That 500 calorie per day would have to be sustained over a certain period (and I confess not knowing exactly how long it would take but it's certainly more than 24 hours) in order to cause a metabolic slowdown. Even then, you can see, there wouldn't be a complete end to fat loss, just a slowdown. People tend to post that they are not losing at all and then wonder if they are in starvation mode, when the most likely culprit is that they are eating more than they should be for fat loss.0 -

Meal timing has no effect on weight loss.

This.
Plus, your body burns calories 24/7. The majority of your daily calorie burn comes from just keeping your body alive, whether asleep or awake, night or day.0 -

If you chronically undereat for a long time, like many months, your body will start to use more and more muscle to feed itself (as muscle takes calories to maintain and fat really doesn't). Less muscle means a slower metabolism.
This isn't going to happen in a few of weeks, much less a few days.
