<p>I’ve been working to lose weight recently and for the past couple of days I have had almost no appetite to speak of. For example, today I ate 660 calories and spent 2:15 on the rowing machine, burning about 710 calories . That’s about -50 calories, and I have no desire to eat. Not that I’m complaining- but has anyone else experienced this?</p>
<p>I have but only immediately after a work out. Not for the whole day though, I don’t think it remains for the whole day.</p>
<p>Taking in fewer calories than needed to support body function can make a person lose his or her appetite, and it’s not a good sign. If you really want to lose weight, please see a doctor or nutritionist to set realistic goals and develop a healthy plan. You aren’t leaving yourself enough calories to maintain your brain and organ tissue</p>
<p>Upintheair, I’m concerned about you exercising to make up for what you eat, because this is how eating disorders present in some people. Please don’t take offense at this; I don’t know anything about you, how long you’ve been doing it, what your health status is; I’m just going by the bare description you posted. But please give it some thought.</p>
<p>what conyat said</p>
<p>over two hours on one machine is indeed a warning sign, and also that you know your exact calorie count</p>
<p>Agreed. </p>
<p>10 char</p>
<p>Up, this could be serious. It sounds like me as a teenager–an anorexic teenager. Time to see a Doctor I’m afraid. You need to nip this in the bud.</p>
<p>The focus on calories means you are studying labels and watching the calorie counter on the machine. ASAP, find a therapist with eating disorder specialty. There are healthy ways to lose weight, but you need guidance.</p>
<p>“For example, today I ate 660 calories and spent 2:15 on the rowing machine, burning about 710 calories . That’s about -50 calories.”</p>
<p>This isn’t how metabolism works. You’re actually closer to -2000 calories, or should be at least. This is extremely unhealthy. Stop being on the machine for so long and start working your way back up to a healthy diet. There is no reason to eat only 660 calories in a day.</p>
<p>I, unfortunately, can eat 660 calories in a SNACK!!! I seem to forget that I’m not in marathon training anymore.<br>
Weight loss- need at least 1200 a day.<br>
2 hours plus on a rowing machine? Shoot me now.</p>
<p>A loss of appetite when severely reducing your calorie count means you have entered “starvation mode”. You will not lose fat at this stage; rather, your body will begin breaking down muscle mass for fuel. You have to eat enough calories to lose weight (fat). I suggest joining a free group, like sparkpeople.com for more information on how to eat enough balanced calories to sustain weight loss.</p>
<p>Oh, I’m not anoxeric; trust me! In fact, I’ve been exercising in an attempt to increase my appetite, but it’s not working. For the past three days or so, I’ve just felt sort of naseous or just not hungry. It’s odd.</p>
<p>Not normal…you should see a doctor about your appetite, can be some other medical issues you need to have checked out</p>
<p>um, when are you naseous?</p>
<p>As other posters have said, if you don’t eat, you stop getting very hungry. </p>
<p>Make yourself eat healthy, high caloric foods and drinks, and your appetite should return. If you can’t keep food down or you continue to have no appetite, see your doctor. </p>
<p>If you continue to eat at the level you are now, you will find yourself with headaches, weakness, double vision, blurry vision, dizziness, and more. You need food to keep your body running. Eat foods high in calories, get some sugar to keep your blood sugar OK, keep your electrolytes in balance by drinking gatorade or something similar, have some fat, and get some vitamins. I do hope you are have plenty of good fluids, particularly sports drinks. If not, you’ll soon find yourself in the hospital hooked to an IV, and they’ll probably make you talk to a mental health professional.</p>
<p>Why would I eat high cal foods if I’m not hungry? Isn’t that really counterintuitive-? And, more importantly, why would I eat high cal foods if I’m trying to lose weight</p>
<p>Because otherwise you’ll starve.</p>
<p>Your body needs calories, fats, etc in order to run properly. The most likely reason for why you are not hungry is because you are starving your body. As many posters have said, if you do not eat, your body acts as if you’re not eating because you don’t have access to food. It’s smart evolution. You stop getting very hungry, for a while, and your body begins to store anything you feed it. At the same time, you’ll find yourself becoming weak, tired, out of sorts, or dizzy; you’ll get headaches, maybe your vision will become blurry, among other possible effects. You need to eat high calorie foods because starving your body is bad. You will probably get hungry again after your body recognizes that it can rely once again on being fed. </p>
<p>You are trying to lose weight in an extraordinarily unhealthy way. Please see your doctor to discuss how to lose weight safely and effectively, if you do in fact need to lose weight (which your doctor can tell you). If you still do not have an appetite after eating well for a couple of days, ask your doctor about that as well.</p>
<p>I’m concerned about your liquids, too. Please make sure that you are drinking enough. I strongly suggest sports drinks to even out your electrolytes. They can throw you really out of whack if you’re not careful.</p>
<p>Disclaimer: I’m not a doctor and not pretending to be one.</p>
<p>When you restrict your calories to the point where you are taking in very few calories, your metabolism changes. It slows way down, as it doesn’t need to burn as much fuel. (which is why you aren’t hungry.) Your body can only maintain this state for so long, and then you will start feel the need to eat again. What you’ll find, is that your metabolism doesn’t rachet up again just because you are eating, again. It may stay lower, and you won’t be able to eat as much as you could before without gaining weight. That’s why so many people gain weight back so quickly after dieting, and often gain more weight than they had before they started.
Yo-yo dieting usually results in more weight gain, not less.
Corranged is right - what you’re doing isn’t healthy. Nor is it likely to lead to permanent weight loss.</p>
