why starvation mode effects some and not others...

There was a big debate going on about starvation mode, I said it was a myth and a lot of people said "i have experienced it." Other says "I ate very low calories with no effects of starvation mode."

They mostly said "it's true because the great authorities say so." So here it is. Stravatoin mode is a term to describe when someone loses muscle mass due to a low caloric diet inhibiting their fat burning abilities. The less muscle mass you have the less calories you burn.

To clarify some said, "I ate low calories and I didn't lose weight." Other said, "i ate low calories and i still lost weight."

I told them "its the macro nutrient ratios you used" some didn't buy it cause I didn't get in to detail about it. Here are the details.
Your immune system requires amino acids, which is found in muscles. When you're on a low calorie high carb diet, it's difficult to get amino acids to the immune system. Your system breaks down your muscle tissue to get amino acids to the immune system. This is your loss of muscle mass, which in turn leads to a lower metabolic rate. For those of you who don't know this high carb diet, also increases blood sugar in the body, when blood sugar is in the body above 110mg insulin is released, insulin is released to lower your blood glucose levels. It clears the blood stream until your blood sugar is under 110mg. It does this by storing the glucose in your muscle(which are probably already full cause you're on a high carb diet) if it can't store glucose in the muscle it will store it as body fat. This is your fat gain, and loss of muscle mass, aka your myth of starvation mode. Notice it doesn't have much to do with caloric intake, it's about macro nutrient ratios. Of course you need a certain amount of protein for your body. If you go to low you won't be able to meet those requirements, and muscle mass is also loss. Your body just can't support your current muscle mass with too little calories.

The people who do eat low calories with out the plateau is due to higher protein levels. Enough protein to support most of the muscle mass, and also the immune system requirements. You either have higher carbs, or higher proteins (not taking fats in to consideration). You also do need carbs, your brain runs on carbs, your brain is the "mac daddy" of the organs. Everything that can be done to keep the brain running will be done. Protein can get converted to glucose this process is called gluconeogenesis. Don't mis interpret this information with "I'll just eat protein then."

I know someone who was eating 1000 calories a day, it was a male. That's very low for a male, and he lost a lot of weight. I asked him "what where your macro nutrient ratios" he told me "mostly carbs." For a second.... this made no sense to me at all. I said to myself "how is that weight loss even possible with a diet very low in calories and high in carbs?" Then i was like "duh" I asked him "how much did you exercise?" He said, "60-120mins of high intensity cardio" Now it made sense. He was burning up all the glucose in his muscle, and once glucose is gone, the muscle burns fat. High intensity uses muscle fibers 2A and 2B which burn up carbs quickly. It's very possible to lose weight on a low calorie diet, just depends on how you do it.

I personally don't recommend a very low calorie diet, don't think that's what I am trying to say. Either way you still lose muscle mass, remember your mac daddy brain? it runs on glucose, if you take in little carbs, it will convert muscle to glucose so the brain can run.

This pretty much means a diet needs to be constructed from a protein basis so you can meet your daily protein needs. This is done by knowing your lean body mass. Your lean body isn't how much you weigh, it's your solid muscle mass. You need to get your body fat measured to calculate your lean body mass.

if you're sedentary you multiple your lean body mass by .5
light activity * by .6
moderate * by .7
active * by .8
very active * by .9
athlete * by 1.0(or just 1)

Whatever macro nutrients ratios you use, should be based around your protein requirements. Feed the body, not the fat.
