How young are you? I tried this kind of stuff back when I went on a diet at age 12 1/2, lost 13 lbs., but of course, gained that back and much more. Not the best idea. See a real dietitian face to face, that will help set you up with a daily menu that will be nutritious, yet still help you lose weight.

if you drive a non-hybrid midsized sedan and only fill it with 3 gallons of gas will you be able to go 400 miles? odds are no. the 1200 minimum is for getting your nutrients in, but the fact is that unless you're a very small, sedentary or elderly woman you need more calories than that. so eating less than half of that on a regular basis is not so much a great idea.
there are only a few exceptions to this. if this is something that happens really rarely [like less often than once a month] that's probably okay, particularly if you tend to eat a little more on the days around it to balance it out. if you're sick and are having problems holding down food, it's fine to go low, though if this is a persistent problem get to your doc to be checked out. and again, the more often this happens the more you should be concerned. or if you work odd shifts to the point where you're basically asleep for most of one day, it's fine to go low on that weird, sleepy day. but this is another place where you should be making up most of those calories on the day where you're awake more.

if you're really consistently feeling full on 560 cals, do check your math and measuring. odds are you're missing something or using some information that is off and you're really taking in more than that.

there are times I do eat less, but I try to eat at least 1,000 calories a day.

Less is not more, when it comes to losing weight! When you make a 500-calorie deficit between what you eat and what you burn, your body will (more or less, mostly) happily shed off a pound a week. If you make a 1000-calorie daily deficit, maybe your body will begrudgingly drop a couple pounds a week. If you try and make a 1500-calorie or more daily deficit (which - you would be doing, by trying to eat in the 500-cal/day range)... you might think great, now I can drop Three Pounds A Week but instead, your body, sensing catastrophe, will do whatever it can to slow down your metabolism and stretch every last calorie as far as it can possibly go. You'll lose weight, sure, BUT it's the law of diminishing returns in effect here. You will make yourself sick, deprive yourself of essential nutrition, muck with your metabolism (which tends to show up as a "predisposition to regain quickly" later on down the road) and all this just to lose the same 2#/week that you could have been losing while eating 1200 cal/day.

Now. If you have ONE day where you feel full at 500? Maybe you're ill, and just don't feel like eating as a result.. maybe you ate a lot yesterday and are still feeling full... if it's ONE day, then really, no big deal. Your body doesn't shift into "starvation mode" at the 24-hour mark. Just... don't think you can sustain that manner of eating for several days in a row on the hope that it will speed up your weight loss. It really won't... but it will set you up for a host of other consequences that you really don't want, in the long run.

Let me add to the discussion. If you're eating ONLY 1200 calories daily, they ALL need to be what we call nutrient dense calories. The assumption that 1200 calories is the minimum to get all the nutrients your body needs is made with the idea that you are eating the appropriate amounts of proteins, carbs and fats ... all of which contain your needed nutrients.

What does the Spark program tell you is your calorie range when you plug in all variables for your program?

Good on you for asking these kinds of questions!! Best to you on your journey!

Years ago I knew a girl who was anorexic and she at 500 calories at the one can live on that caloric intake. ARCHIMEDESII is correct ...that is a starvation diet which will just lead to binging later.

560 calories a day is a starvation diet. You may feel like you're full, but you really aren't.

Nutrition experts will tell you that the bare minimum an adult woman should eat to ensure she gets all the vital nutrients and minerals her body needs to function properly is 1200. So, if you're eating 560 calories, you're probably deficient in a number of different anti-oxidants, vitamins and minerals.

An adult woman can NOT function on 560 calories per day. You may not feel it right now, but if you were to continue to eat this many each day, before long you would start feeling tired, fatiuged and cranky. With time, your body will tell you that 560 isn't enough. What happens ? you'll begin to overeat.

I know that 1200 calories might seem like a lot, but it really isn't to keep an adult woman healthy. I know this is going to sound strange, but a person has to EAT in order to lose weight. Starving doesn't work. It never did. Starving just leads to binging later.

If you eat 560 calories, then is it not fulfilling your requirements of 1250 calories a day? Can you eat less, if you are truly full?
