Is it TRUE?

Is it true...That if one exercises and loses a lot of calories by exercising and only eating a certain amount of calories for that day for example...Someone consumes 800-900 calories and then exercises and burns 300-400 calories...They will not lose weight by doing this?? I have heard doctors say this because it will put our bodies into "starvation mode" then I hear people saying that is not true that it is a myth. Do any of you post op sleevers have any insight to this? Has anyone been doing this and they weight loss stopped or sped up?? Thanks for any feedback.

Complete, utter nonsense. I get so tired of starvation mode malarkey. 

Try eating 800 calories every day and exercising. Do you really think you'did weigh the same a year from now? 

It just doesn't work that way.

I find that fit bit credits me a ton of extra calories for my exercise but I don't see extra weight loss.  So I wouldn't increase my calories to match the exercise.  I just ignore the calories from exercise.

Starvation Mode is bunk the way most people understand it. There are several studies/articles now available online for you to read that explain the myth of starvation mode. Basically what it boils down to is that as you lose weight you need fewer calories to maintain your lower weight. Our bodies are also hardwired to fight weight loss, which has something to do with the whole myth living on and on. Understanding how the hormones Ghrelin and Leptin work in your body will help you understand this "Starvation Mode" myth and where it comes from. 

If you want a basic understanding of "Starvation Mode" check out the following link. The article gives you an overview of the metabolic changes that can occur to cause weight slow down during weight loss. The last section is headed "Starvation Mode is Real", but be careful to read what is underneath the heading. The author is very clear that "Starvation  Mode" is not at all what people claim it to be.

Not only do you need fewer calories as you lose weight, you would need fewer calories per day than someone of the same weight as you who had never been overweight.  Being obese permanently alters your physiology.  So, when that always-been-skinny person tells you "it's okay to splurge sometimes. it won't hurt your diet" just tell them to p*ss off (just kidding), and that it's different for you - while 800-900 calories per day might be starvation for them, for you it's the new normal. 

And, on a (sort-of)related note, some skinny (~6', 140 lbs) coworker offered me the rest of her box of donuts the other day. I just said "no thanks, I don't like sweets" with a totally straight face. She just laughed and said "not me, I love sweets. I eat them all the time."  ugh  I wish never-been-fat people truly could understand the struggle.
