It's a myth.0

Based on personal experience it is a truth, but under 400 kcal/day0

Thanks. I am not well educated in this and sometimes you get so many opinions it makes you confused.0

It depends on what is meant by starvation mode. The body does start shutting down less critical functions when it doesn't get enough calories. But some people have the idea that the body could actually stop losing weight while in starvation mode. That is a myth.0

What you experience was probably severe muscle loss and metabolic adaptation/adaptive thermogenesis. If you starve your your body, your metabolism will become more efficient and burn less calories.

I totally agree with you, it was metabolic adaptation.0 -
It's a myth.
Yeah, no. en.wikipedia.org/wiki/Cortisol
It's a real thing. Not nearly as drastic as some people claim it is, but it's real.
You have to do some pretty mean things to your body to trigger large spikes of cortisol production. Being in an excesive calorie deficit is one way to ramp up cortisol produciton in your body (others include just stress in general, lack of sleep, etc.).
The TL;DR for the wiki: Cortisol basically does everything it can to minimize your body's energy consumption in order to maximize the time you can "survive". I am sure it was very useful to our primitive ancestors, but not terribly useful to us anymore. It tries to make you physically lighter so it takes less calories to move (reduces muscle mass, bone density), it reduces immune function, cell growth, slows the metabolism down, etc.
Basically, just don't be an idiot and you won't have to worry about it.0 -
OK. Thanks for all info. As to why she wants me to try this, ? I think she feels its enough to sustain my body and still lose. I am about 50 pounds overweight. I do feel fine, and am losing weekly, not rapid, but steady. It was just a question posed to those of you who are more informed with facts.
Thanks again0 -

If it is being medically supervised, follow the advice of your doctor.0 -

^this.
You should be laying down good habits now, so you will be successful long term.
Slow and steady really does win the race!0 -
OK. Thanks. Is 1 -2 pounds a week considered "magic"? I am not being snarky, I am really asking. I thought that was reasonable. Most weeks its not 2. Maybe0

You're 50 pounds overweight and your doctor is recommending you go on 1,000 calories a day?
Personally, I'd be looking for a new doctor.
And yeah, starvation mode is a myth.
