THE BIG STARVATION MODE MYTH.

Here is another thing to keep in mind Fat just sits there. You do not burn any energy to have an over abundance of fat. Fat is a storage shelf for the body. Think of it as the closet you jam things in you might need down the road (energy), or things you don't know how to get rid of (toxins). It just sits there closed, and you never look into it until you need something. Lean muscle is used constantly (so it needs energy constantly to maintain). It is like the kitchen in a house full of people, there is always someone cooking in it. The more lean muscle you have the more fuel it needs (the more you have to cook). If you are overweight, and you stop taking in more junk than you really need (to shove in the closet), and start building more lean muscle(cooking in your own kitchen kitchen) your eventually going to need that pan your mom bought you in that storage closet. Guess what that pan, is at the bottom of the closet so you have to clean it out to get to it, and then you find the hiking boots(exercise) you have been looking for to build even more lean muscle(means more energy is needed). So now you have to cook more food in the kitchen, but you don't have anymore pans in the closet, because you have cleaned out the junk. Now you have no choice but to go buy another set, and keep cooking more food, more often to keep up. Nothing is stored, and nothing is wasted. This is how our bodies should be. Hormones are the lubricant to keep the body functions moving, and keep us from becoming content with the closet full of junk we might need down the road, if life changes. It works for me to see it this way, but maybe not for you. I hope this info helps someone else that the only reason I am writing novels here...lol If someone has a better way to put it, or something else to add to the collective wealth of knowledge please enlighten!

So this was a total ramble to try to say how I picture the studies I have read, and how I perceive the body using fat, and energy, and how lean muscle is built. It was really bad...... I am not a writer by any means. Please excuse the poorly written analogy and just understand the bodies exposure to hormone shifts caused by poor diet choices. (i.e. super low calorie diets for extended periods of time, and/ or nutrient lacking foods)

so starvation mode is like an old set of pans that do not work any more????

This is what I was trying to say in a very long winded terrible ramble is.... Fat is a storage facility in the body where the liver our bodies filter can store an overabundance of energy to be processed later if needed. Toxins can also be stored in fat for the body to deal with later if the liver is too busy extracting the important nutrients our bodies need. Muscle, is in a constant state of movement, and therefore needs energy to maintain it. If we are obese, and we cut our caloric intake than our bodies do start to use the stored energy in our fat. If we build more lean muscle through exercise we will need more energy to maintain the new larger muscle mass, and than our bodies will use more of that stored energy in our fat causing it to shrinks. Right? However, if we stop feeding ourselves, or cut calories too low than our bodies say, "Wait a minute.....something is wrong we have not had...Fat,... or Carbohydrates,.. or Protein in a few days. Whats wrong? OMG maybe we need to stop supplying the muscle so much energy, and hold a little back in our fat stores. Let the muscle starve a little for the bodies greater good." This is when Cortisol kicks in. Now, understand Cortisol is important in the body. It is part of the "Fight or Flight" response in our body allowing us to prepare for danger or cope with stress. Like needing to run away from something that wants to eat us, or there is not enough food for us to keep functioning at this level of energy use. Cortisol is released by our Adrenal Gland, and if levels become too high from constant stress, or from not eating enough of the right foods.( where our bodies think it might be awhile before we get fat again, or protein again, or carbohydrates again) The increased Cortisol signals the Thyroid which is responsible for telling the cells how quickly to "burn" energy. The Thyroid slows down it's important hormone production by sending a signal to the Hypothalamus to slow production of HGH in the Pituitary gland, so the energy "burn" slows down by the Thyroid which slows down production of important hormones needed to tell the cells "burn" more energy. This then slows down fat storage be burned for energy, and to hold on to it for the future in case it needs it later, and so the body can then lower the Cortisol levels back to normal. Then when the body perceives cortisol levels are lower, and we are no longer in "Fight or Flight", and hey look we are getting the fat, and/ or protein, and/or carbohydrates we needed again. The Hypothalamus says OK lets pick up energy use again to maintain our muscle, and HGH goes back up, Thyroid function goes back up, we "burn" more energy again. Insulin is part of this function too, If we avoid peaks, and valleys by eating consistently enough that our bodies get a gentle roll in our bloodsugar levels instead of spikes, and than dramatic drops our bodies see this as an abundant food supply is at hand we can afford to let go of some of the stored energy to help the energy "burn" in our cells so we can grow lean muscle which uses more energy, and we have plenty of good nutrient rich food to do that. My idea of what "starvation mode" means , nothing like real starvation as in, dying because there is not enough to even maintain normal life function. It is "starving" your cells of a well balanced nutrient rich diet, through poor caloric intake for you own person. This means you need to find the right calorie intake for you! The way I think we do this is by trail and error. You have to have variety (to ensure you are getting all the nutrients needed), consistency (so your hormones such as Cortisol stay balance to optimize energy "burn", and just enough calories (to keep you satisfied, or not hungry {so you don't binge and throw off your bloodsugar level}). Since some of us are heavily muscled, and some are not we require a specifically tailored amount of calories to maintain the balance. The more lean muscle, the more calories you may need to maintain that lean muscle. The less lean muscle you have means, you need less calories in your daily diet. Exercise is important to build the lean muscle needed to burn more energy. The calorie intake is important to maintain hormone balance to let go of fat stored. Both components are important to losing weight, but understand they are different components that have to work together to achieve your ultimate goal of a slim, well muscled, lean you. So still long winded, but way more technical description of how I understand what I have learned than any analogy I could try to spit out. I promise I will never try to story tell again. I will stick to the facts.

the only thing worse than a massive wall of text is a requote of the same with a word or two added at the bottom.

...and if I recall the math correctly, a pound of fat burns somewhere around 2 calories per day; a pound of muscle burns 6. So a 20 lb. increase in muscle mass (which is a quite remarkable increase) would increase one's calorie burn by 80 whole calories per day.

Pretty sure it says 1200 for everyone. Personalized service lol.

Wait, wait, wait. When I first entered all my stuff into MFP, they said they were calculating it based on body fat/height/weight/whatever to determine how I could healthily lose weight and how many calories I should have to help me get there and it was 1200 calories. I always thought that people who were starving themselves were the ones eating like 500-600 calories a day. But, anyway, I'm really confused. Of course, I nearly always go over my calorie goal by 200-400 calories (I TRY not to, but it's hard and I don't log as much as I should).
