I copied the article below from CC library...sounds like we should be eating gums and leptins, but I don't know what foods these are in. Hopefully someone can let me know.
The effect of fiber
Fiber is not a single food, but rather an indigestible complex carbohydrate. Since the body cannot absorb it, it has in itself no calories. Nevertheless, fibers called cellulose and hemicelluloses take up space in the stomach, making us feel full and therefore landing the top spot of calorie counters? friends.
But before we hand out the gold medal, let?s have a closer look at this champion. It turns out, namely, that not all fiber comes with the same benefits. For example, bran will mostly get you larger and softer tools. This kind of fiber "bulks up" waste and moves it through the colon more rapidly, which is not a bad thing, but probably not what you were looking for.
Strangely, the fat-fighting property of fiber is found in gums and pectin's. They keep cholesterol under control by removing bile acids that digest fat. The same types of fiber may regulate blood sugar as well. This is accomplished by coating the gut's lining and causing the previously mentioned delay in stomach emptying.

anyone?
Here is something I found when I googled fiber, pectin, and gum:
Dietary fiber comes from the portion of plants that is not digested by enzymes in the intestinal tract. Part of it, however, may be metabolized by bacteria in the lower gut.
Different types of plants have varying amounts and kinds of fiber, including pectin, gum, mucilage, cellulose, hemicellulose and lignin. Pectin and gum are water-soluble fibers found inside plant cells. They slow the passage of food through the intestines but do nothing to increase fecal bulk. Beans, oat bran, fruit and vegetables contain soluble fiber.
In contrast, fibers in cell walls are water insoluble. These include cellulose, hemicellulose and lignin. Such fibers increase fecal bulk and speed up the passage of food through the digestive tract. Wheat bran and whole grains contain the most insoluble fiber, but vegetables and beans also are good sources.
It sounds to me like both kinds are in most fruits, veggies, beans, and oat bran?
