starvation and weight loss

Options
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?

    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.

    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.

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

    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.

    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.

    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.

    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 only applies to people who under eat, this would not apply to someone who just ate one big meal everyday but was still meeting their calorie goals.

    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.
