Do your metabolism decreases when your calories intake is low? Why???
154534
Absolutely.\n\nIf you consistently decrease your calorie intake (through dieting) without increasing your physical activity levels, you risk reducing your BMR (base metabolism) levels, forcing your body to burn less calories, which may eventually lead to further long-term weight gain and make it more difficult to lose the weight you've gained. Unfortunately, this is the scenario that most dieters face as they continue their desperate attempts to lose weight through dieting without physical activity. As we age, those who solely depend on dieting as a method of weight loss become even more frustrated since BMR levels naturally decline as we get older. \n\nAny weight loss people experience on low-calorie diets is temporary unless physical activity levels are increased.  This applies to any diet plan out there.  It's a matter of a physiology analogy.  Turn down the furnace and you get less heat.  Less heat means slower rate to burn energy.  Eventually, if you don't turn up the furnace, you'll always have less heat to burn energy and you'll gain back the weight you lost...and more.\n\nSo how do you avoid falling into this vicious cycle? If your between 20 - 55 years of age, your AMR (active metabolism) should consist of at least 120 - 200 minutes of moderate or heavy physical activity weekly. To prevent injuries and enhance recovery, the older you are, the more you will have to stay in the lower end of this range. If you're 55+, you should seek the guidance of an Exercise Specialist and your Physician for an appropriate guideline according to your health and fitness level. \n\nYou can calculate your BMR and AMR here:\nhttp://www.preventdisease.com/healthtools/articles/bmr.html

Eat atleast 1500 calories a day to keep your body from shutting down in survival mode and that will slow your metabolism down and it will help you stay at your weight.  Exercise, that's the number one key.

1. eat smaller portions more often...basically don't let yourself feel hungry.  if your body feels hunger, metabolism will slow down (your body's way of adapting to the fact it doesn't have food...survival mechanism).  \n\n2. exercise!  working out or doing cardio for an hour will throw your metabolism into overdrive for a few hours.  let's say you burn 300-400 calories in an hour exercising...your body will think that you need LOTS of energy so it will burn pretty everything it can for energy.  this is probably the best way to boost metabolism.  of course you gotta eat if you workout or else your body will just break itself down.\n\nplus, having more muscle causes your body to burn more calories just to maintain them...for example, you will burn more calories walking if you have larger leg muscles since it takes more energy to operate them.

An intake between 1200 and 1400 calories per day is considered a low intake.\n\nCaloric intake BELOW 1200 should be avoided. It will lower your metabolism (so you actually start burning fat slower). Also, you most often will NOT be getting the nutrition you need, resulting in brittle bones, messed up periods, hair loss, and tooth decay.\n\nSexy huh?

Congratulations on your high metabolic rate and yourself lucky. Some big people want to lose weight and can't no matter how hard they try. This goes the same to those thin ones who want to gain weight but can't no matter how much they eat. But then again, your metabolism might change as you grow older, as it tends to slow down...thus you start to put on some pounds. So be as active in life as you can to maintain your metabolism in a tip-top shape!

Because you have internal mechanisms which will make your body shut down certian operations in order for survival. What's going on is your body tells you it's hungry in an effort to get you to eat, once it figures out you aren't going to be eating anytime soon, it shuts down certain brain functions to conserve energy. Now, at the same time, your metabolism slows down meaning you aren't burning the most amount of calories. \n\nTry to avoid this as much as possible by eating  non sugary foods often. Sugar spikes your insulin levels and makes you store fat. I personally believe that the introduction of "coca cola" was the onset of the "Fat American". Look at the point in history where it became popular and look at magazines from those same times and you will see what I'm talking about.

I have been on an 850 to 1000 calorie a day diet, and walk at least 2 miles a day.  In 4 months, I have lost 50 pounds.  Drink 8 8oz. glasses of water a day, and fill up with fiber.  You have to expend 3500 calories more than you take in to lose 1 pound, so keep moving!  Low-cal diets can cause your metabolism to slow down, but lifting some weights and the exercise will keep it up, so you kind of even it out anyway.  Good luck!  (And it is safe, I spoke with 5 dr's that I work with and my family dr. before starting this diet!  Just make sure to take a multi-vitamin because it is hard to get all your nutrients in this diet with food.)

Many women after 30 will sometimes notice a decrease in their metabolisms.  When I work with women this is very common and the good thing is that you can learn how to re-set your metabolism.  What you don't want to do is cut back on your food intake, especically if it is low to begin with.\nMany women make the mistake of doing this and it actually is counterproductive!  The key is to eat small meals about every 3 hours.  This will help boost your metabolism.  Also eat protein with every meal.  Most women that I have helped don't eat enough protein.  Eating protein will help increase your lean muscle and the more lean muscle you have the faster your metabolism becomes!  Exercise plays an important part as well.  Weight traning at least 3x a week will help your body burn more fat and it makes you feel good!

I think you should loose it without a problem. Sounds like you're going about it the right, healthy way. I don't think you should cut anymore calories out. I heard that if your body only receives, for example, 1500 cals a day, That your metabolism will actually slow down so that your body can make those 1500 cals last. I'm not adoc or a fitness nut, but I did take a bodybuilding class college and my teacher stressed the importance of maintaining a good diet in order to achieve optimal results. Because you are exercising 5 days a week, your body will need a good, healthy 2000 cal a day diet to have the energy necessary to continue your workout regime. Good luck!

In a sense, say before you begin your diet you take in 3000 calories, your body is used to this even though it may be 500 over what you need. You now begin a diet that is 2000 calories. Your metabolism will eventually adjust and see that it only needs the 2000 and will adjust accordingly. Now say you go back to 3000, you are now getting 1000 more than you body is used to rather that the original 500 over the limit hence the YO YO effect.\n\nHave you ever seen the people who diet and end up looking unhealthy although they have lost lots of weight, that is because they lost mostly lean muscle. This is why it is so important to exercise when dieting because your body will use your calories to sustain your lean body mass, with exercise your body says HEY I STILL NEED YOU MR MUSCLE and puts the calories to good use while loosing the fat.

ya, u probably have a fast metabolism - so tell people that! A fast metabolism is when ur body is able to digest food really quickly and hardly makes u put on weight...i have a fast metabolism and it suits me just fine! eating anything and everything i want anytime without worrying of putting on weight. Just as long as you eat enough for your body to get all the essential nutrients and aren't concerned about gaining extra weight or thinking ure fat when ure actually not, u don't hav a problem at all!

Not really.  You will lose some weight while you are on the juice diet, but once you start to eat normally again, you'll regain the weight that you lost.  Also, those severely low calorie diets cause you to lose muscle which effectively lowers your metabolism.\n\nYour best bet for permanent weight loss is to eat sensibly and exercise.

When was the last time you hada  complete physical? Check out your Thyroid, it may be underactive = slower metabolism. Im not an expert (yet) so go see one!\ngood luck.\nbe sure to mention youre a vegetarian and for how long. \n\nOne more idea- Genetics & lifestyle.

Ive found that watching what you eat and combining that with cardiovascular exercise helps to make your metabolism faster :) I went on a mega binge (for about 4 days) after watching what i ate and exercising for about 3 weeks and so far i havent put on any weight. Im putting it down to the fact that my metabolism has quickened helping me to burn the excess calories :)

Most likely you've increased your muscle mass.  Muscle weighs more than fat.  Do your clothes fit better?  If you aren't eating enough your body could be holding onto every calorie you put into it because it's in survival mode.

No, it will decrease your metabolism because it is the same as drinking water. While drinking water can boost your metabolism, however, without food, it will actually decrease it.

I took it a while back and it made me feel 'off'. Shortly after, I took a nutrition class at a local college over the summer and learned a ton of stuff about nutrition and healthy living. I also learned how bad diet pills are for you. After you've been taking them a while they eventually slow down your metabolism so that when you get off of them you have to force yourself to eat less and exercise more just to maintain the weight you are at. I know it sucks but the only real way to lose weight and KEEP IT OFF without screwing up your metabolism is by cutting 500 calories from what you normally need. (You can find out online) and doing a minimum of 30 mins of moderate exercise each day. Hope that helps!
