I'm always looking for ways (beyond crunches, aagh!) to keep my post-baby waistline trim. But I've learned about a cooking trick that goes beyond just eating low-cal to lose weight: there are actually two dinner ingredients that can help reduce abdominal fat.

Research suggests that eating more whole grains or including vinegar of any type in your diet may help reduce total body fat and abdominal fat, according to an article Ana Mantica wrote for the July/August issue of EatingWell Magazine. Here's a quick synopsis: Learn more about why these two ingredients can help whittle your waistline here.

1. Whole Grains
Swapping refined grains for whole grains may help reduce total body fat and abdominal fat, according to new research in the Journal of Nutrition. Researchers speculate that the fiber from whole grains may help you feel full with less food-and possibly fuller than fiber from other sources, such as fruit and vegetables. Aim for at least three servings of whole grains daily (one serving equals 1 cup of whole-grain cereal or a slice of whole-wheat bread).

2. Vinegar
In one Japanese study, when obese adults added about 2 tablespoons of acetic acid (the active ingredient in vinegar) a day to their regular diets for 12 weeks, they gained 4 fewer pounds, about 5 percent less belly fat and 3.5 percent less total body fat than adults who didn't consume any acetic acid. Researchers suspect that the acetic acid ramps up enzymes that oxidize fat, so less fat accumulates. Add any type of vinegar-even a tablespoon-to your daily diet.

So our editors combed through the EatingWell recipe archives to find recipes that include both of these ingredients-whole grains and vinegar-to help you stay trim. Find 14 recipes to blast belly fat here. Here are 3 yummy recipes to get you started:
