Can't stop eating

Are you over restricting your intake? Maybe you set your weight loss goal per week too high.

If there's one thing I've learned it's that you have to track. Even if you are cheating. Even if you are on vacation for a week at an all-inclusive resort where every meal is buffet style and you don't really know the calorie counts of anything. You have to log. It makes such a difference.

Start with getting back to logging. Even if it's one bite of something. Just the act of logging can make you aware of just how much you're eating, which can work in your favor. I know for me, even if my logging is off, just the act of putting down what I've eaten makes me more aware of things and I make better choices for dinner or snack.

You might also start with just not finishing your kid's food. I know, it's really hard to let that go, espically if your parents are of the "starving kids in China!" variety. ^_^; Leaving food on my plate when I've hit my limit is really really hard, and I still feel bad for it, but I also know I don't need it and I'm better off not finishing.

Something else to consider. You could be a person that will do better on several small meals over the course of the day. Time of day you eat has no bearing on weight loss, so if you want to spread out your meals to 5-6 times a day, as long as the total calories at the end of the day is in your limit, you're fine.

I recommend you take a moment to ask yourself why you are eating each time you are tempted to put something in your mouth. Be honest, don't tell yourself you are finishing your kids' plates because you don't want to waste food, that is an excuse, not a reason. First you have to be honest about the why, then you can start to change it.
A couple of "tricks" are
drink water instead of eating
talk yourself out of it, if you know you've already eaten enough remind yourself of that
ask yourself would you eat an apple; if the answer is yes, then eat an apple. If the answer is no, then don't eat

I know the feeling, just trying to keep logging and reduce the snacking a day at at time. All the best with it!

Keeping healthier foods instead of junk food in the house will help greatly. I would hazard a guess that your house currently has a bunch of chips and cookies and sugary cereal and sodas and pasta and pizza, etc. That's stuff that you should not be eating much of anyway, let alone on a daily basis.

If you stock your fridge and pantry with healthier foods instead, like lean meats, vegetables, eggs, bran cereal, nuts, oats, whole grain bread, etc., you will tend to eat less because it's not as "fun" to eat those things. And that's the real issue here. You seem to be, like most people, looking at food as entertainment rather than just fuel for your body. That's not what food is supposed to be. Healthy food generally doesn't taste as good as junk food, but that's life. We as a species weren't meant to be eating sugary carbs and cheesy products and fatty dressings and condiments all day. We just do it because it tastes better and it's available to us and we consume them under the guise of "eating," when we're really hardly ever actually hungry when we eat those things, and instead mainly eat them just for entertainment. Have you ever heard the quote, "If you're not hungry enough to eat an apple, you're not hungry"? Most people should take that to heart. Whenever you think you're hungry, imagine eating a few apples to satiate your hunger. Would you do that? If not, you're probably not actually hungry and you're just wanting to eat something as entertainment because it tastes good.

In summary of the above, keep healthier foods around instead of junk food, so you won't be tempted to eat as much as you do.

Now, you're probably thinking that your kids will hate that. First off, you should be teaching them healthy eating anyway, to the point where they shouldn't expect that every meal contains chips and cookies and pizza rolls. But, kids being kids, of course you can't run your kitchen like the military and only have healthy foods there and nothing else. So make them a bit of junk food along with their healthy food with their meals, like a small cookie after their healthy sandwich and veggies. But make sure to only fix for them what they will likely finish. You said that you always finish your kids' food - well, that clearly means that you are making their portions too big for them every time, doesn't it? So make less food for them so there aren't as much leftovers as they currently typically have. Then you won't have much of anything of theirs to eat when they're done.

In summary of the above paragraph, have some "fun" food around just for your kids for them to have alongside healthy food with each meal, and do that to teach them generally healthy eating. And only give them what they will eat, so there are no leftovers for you to eat.

And, all that said, allow yourself a couple cheat days here and there, because dieting nonstop will drive anybody crazy.
