The "Hunger Games" series dished up a movie annually from 2012 to 2015 to satisfy its fans' craving for yet another dystopian story of girl power, with Jennifer Lawrence starring as Katniss Everdeen. But Lawrence seems to know when enough is enough. She's declared that she’s taking time off for a year (at least).

If you have a hard time knowing when enough is enough, and always crave just one more bite, you know tapping down your hunger is no game. But there's good news. New research might help you stop overeating.

Being obese interferes with the proper functioning of your appetite, interfering with the regulating gastrointestinal hormones leptin ("I'm satisfied") and ghrelin ("Feed me!").

Researchers have identified why another appetite-regulating, gastro-hormone, uroguanylin, stops doing its job. It turns out that it's not obesity but overeating (especially carbs and bad fats) that keeps the hormone from telling you it's time to stop taking in calories.

The good news is that uroguanylin production cranks back up when you stop overeating, even before you lose weight. Here’s what you can do:

1. Eliminate processed carbs, bad fats, and added sugars and syrups from your diet. Drink plenty of water. It helps control hunger. Stick with lean proteins from skinless poultry and fish.

2. Eat all the vegetables and salad (easy on the dressing) you want. Toss greens with walnuts, avocado, carrots, celery, bell peppers, and artichoke hearts (in water).

3. Start a walking routine (headed for 10,000 steps a day). And sleep 6.5 to 8 hours nightly; your gut hormones like that a lot.
