How do you know if your body is in "Starvation Mode"

I think of it in terms of "nutritionally deficient" more than anything....it was explained to me that when you are nutritionally deficient, you compromise your metabolism and since I def. do not want to do anything to slow down my little fat burnin buddies, I make sure to eat almost all my exercise calories back.

so thats the only way you know if you stop losing weight?

You starve? I'd assume REAL starvation is obvious...

Starvation mode is a state in which the body is responding to prolonged periods of low caloric intake levels. During short periods of caloric abstinence, the human body will burn primarily free fatty acids from body fat stores. After prolonged periods of starvation the body has depleted its body fat and begins to burn lean tissue and muscle as a fuel source.

As long as you keep giving your body something to digest every 3 hours or so and keep your caloric intake above 1,200 you should keep your body out of starvation mode. If your diets calorie goal is below 1,200 per day you need to make up the deficit with exercise and not calorie cutting. Calculate your BMR in the tools section and it will tell you how many calories you burn each day at rest. If you keep your caloric intake below that number you will create a deficit. When you create that deficit your body has to replace those calories from its stockpile of fat. Each pound of fat takes 3500 calories to burn. So in a week if you want to lose 1 pound you need at least a 3500 calorie deficit when you calculate your weeks intake.

Just remember, you need to take in at LEAST 1200 calories (for most people, the number does vary) and create your deficit with exercise.

You won't get pale or orange, your eyes won't get red and you won't grow a third arm Starvation mode means your body doesn't have enough nutrients to work efficiently, so your metabolism slows down and fat loss slows down. It also gets harder to work out and you notice your stamina decreases.

opps

so then even though on the days I exercise im only netting like 900 and have been this way for a year.Since im still losing and my stamina is great im not in starvation mode

Haven't you heard? First your body eats all your muscle mass, then it eats your organ tissue, then you lose all your energy, get REALLY fat, and then you die.

LMAO. Loved that!!

When my body goes into "survival mode" I get really tired and run down and I stop losing fat.

BUmp

Thanks so much!

After prolonged periods of starvation the body has depleted its body fat and begins to burn lean tissue and muscle as a fuel source.

So.... I'm just trying to understand, please don't hurt me... starvation mode (when your body burns lean tissue and muscle as fuel) happens AFTER the body has depleted its body fat?

Would that mean that an obese or overweight person (someone with lots of body fat) would have a difficult time going into starvation mode?

No, starvation mode is a slowing of the bodies metabolism. It still burns fat just much slower. If you were in starvation mode for long enough to burn through all the fat then yes your body would then begin burning lean tissue. No matter how much body fat you have you can still go into starvation mode if the criteria I stated above that is not met.

LMAO :laugh: :laugh: :laugh:

Most days I am at or a little over my 1200. I have been losing 2 lbs a week so far. I do not want to go under cause the thought of Starvation Mode scares the he** out of me. I am just concerned that if the weight loss slows or stops will I be in starvation mode then? Or is it just a plateau? I just want to get to my goal, be healthy look good be happy and not screw my system up in the process. I even swallow a Tbsp. Of organic olive oil a day to get a healthy fat.

The closer you get to the healthy weight for your height and age the harder it will be to burn those last few pounds healthily. So it will slow down and not necessarily mean you are in starvation mode. Keep adjusting your goal by putting in your new weight and it will modify your calorie needs to achieve the goal.

Also keep in mind, when your body enters starvation mode, the caloric intake it needs to not burn fat lowers below 1200 calories. So once you get into starvation mode, there is a chance that the caloric intake that got you into that mess (<1200 calories) will then be enough to sustain you and no longer burn fat. So you need to get out of starvation mode and reset your body so that you can start burning fat in a healthy manner again.

Thank you for clearing that up.
Now, for the record.... because this was the HUGE issue here yesterday. Say a person has an autoimmune disease called Hashimoto's Thyroiditis and they cannot take the medication that would help them (allergic). So! Their doctors prescribe them a "diet" in which they alternate between very low calories and "normal" calorie levels throughout the week (because it causes the body's glucose levels and hormones to go crazy, affecting the thyroid, and reducing symptoms such as severe migraines.) Is that person's body going to eat all their muscle mass and organ tissue, then make them really fat, and eventually kill them? And should that person be called mean names by others on MFP? :frown:
