How do you track? Are you very careful about measuring (preferably by weight rather than volume) or do you "eyeball it?" Do you track everything or are there some things you leave out, thinking they don't make much of a difference? It's possible that when you think you are eating 1500 calories, you're actually eating more.
If you know your tracking is precise, going from 1500 calories/day to 750 calories/day is a pretty huge jump. I'm not sure how physically active you are, but I assume you're pretty active with a set of twin toddlers (congrats, by the way). If you're not getting results at 1500, you can *probably* safely go a little lower than that as long as what you're eating is generally well-rounded and nutritious, but half that is plain dangerous. You're probably best off if you talk to a doctor about *how* low you can safely go, but the range between 750 and 1500 is pretty big.
Some perspective: a sedentary *two-year-old* needs around 1000 calories per day; an active one may need 1400 calories per day. Yes, they are growing and growth takes a lot of energy, but remember how small they are (on average only around 30 pounds, or a bit less).
More perspective: prisoners of Auschwitz received 1300-1700 calories per day at the beginning of the war, depending upon the energy required by the work they were forced to perform, and closer to 500 calories toward the end of the war.
750 calories a day for an extended period will, more than likely, backfire on you eventually. Maybe you'll be skinny when you finally experience the effects of prolonged micro- or macronutrient deficiency, but the effects won't be pretty. A slender woman with less muscle than her equally slender peers, or with a damaged metabolism from extended starvation, will burn less calories at rest and won't be able to eat as much. A slender woman with her teeth falling out still has her teeth falling out. A slender woman with a weakened heart can still die.
I don't meet my required calorie range some days, and when I do meet it, often I am at the low end of the range. But sometimes I'm at the high end of the range, or even higher. Overall, it's averages and patterns that make a difference. And particularly when your intake is low, *what* you eat is as important as how *much* you eat.
Even a very small, sedentary woman needs over 1000 calories per day (SP puts the number at 1200 calories) *if her food choices are perfect,* just to get the proper amounts of vitamins, minerals and macronutrients to keep her body functioning properly. If you're *not* sedentary, *not* very small, *not* eating a perfectly balanced diet (like most of us), *and* eating almost 500 calories less than the bare minimum set for such a woman *every day,* there is no way your body is receiving the fuel it needs to keep you healthy.
Of course, there are exceptions here and there when you suffer from a particular medical need, but almost everyone can and will *eventually* lose the weight if they follow the guidelines, and they won't be malnourished that way. And maybe you'd be lucky and not experience any of those problems, but why take that risk when you can get safe results with just a little more time and patience? Going a *little* low with your intake isn't likely to hurt you significantly (if at all), as long as you've cleared your totals with a doctor. But 750 calories per day for a prolonged period is not "a little low."
Believe me, I've been there. I dealt with a restrictive eating disorder for years. Two years ago, after I'd recovered, I had my first child; I gained a *lot* during my pregnancy, and it was very, very hard not to slip back into old habits when I started trying to lose the pregnancy weight. It can be discouraging to see the scale drop slowly when you are eating the way you should, especially knowing that cutting more calories will seem to show results more quickly (even if the weight lost will include a lot of muscle and bone, too). But those of us with young kids really need to make sure that we provide ourselves with proper energy and nutrition, not just to keep us safe so we can be there for our kids, but to set a good example for them so they will do the same.
Slow and steady wins the race, and doesn't keel over with a heart attack at the finish line.
