How can eating whole grains help me lose weight?

Whole grains have more fiber than other grains. For example, a slice of whole grain bread has 3-6 grams of fiber where white bread has 0-1 grams of fiber. Fiber is known to be filling. This is true because fiber can’t be digested. Humans don’t have the enzymes that breakdown fiber, therefore it moves through your digestive tract undigested, this provides bulk and helps you feel full longer. If you feel full longer after meal you are more likely to eat less over the course of the day.

Whole grains tend to have more fiber and fiber decreases the rate at which your body digests food. This may help you feel satiated longer. It is recommended that adults consume 48 grams of whole grains daily. A good source of whole grain is any food that contains at least 8 grams of whole grains. However, the listing of how much whole grains a food contains is not currently required to be on a food package.

Whole grains promote weight loss in several ways. Because whole grains are made from complex carbohydrates they are digested slowly so they help keep you full longer than quickly digested processed grains like white bread, rice and pasta. What's more, they actually take extra energy to break down. When researchers at Pomona College in California fed volunteers equal calorie sandwiches on either white bread or whole grain bread the volunteers that ate the whole grain sandwiches required twice as many calories to digest their sandwiches. 

While it's easy to get whole grains at breakfast from foods like cereal and whole wheat toast, it's not always as easy to get them later in the day so you need to strategize. Order your sandwich at lunch on whole wheat bread or in a whole wheat tortilla or have a burrito bowl with brown rice, instead of white rice. At dinner, experiment with different grains like whole wheat couscous and pasta, quinoa or polenta. You'll find you stay fuller and feel less hungry.

Eating whole grains can help you lose weight in many ways. Whole grains are very high in fiber and require more chewing time; thus they increase your saliva and gastric juice flow and distend your stomach. In addition, whole grains are more slowly digested and absorbed, so that they produce slow, gradual increases in blood sugar levels that lead to making you feel full for longer. That's why it's really hard to overeat something like oatmeal, but very easy to eat something made of white flour, such as French bread. Studies have shown that eating more whole grains can help you lose weight, as well as maintain a healthy weight. 

Whole grains can provide additional vitamins, minerals and fiber that can assist you with weight loss. Fiber, found in fruits, vegetables, and whole grains (such as 100% whole grain bread, pasta and cereal and brown rice) tend to make us feel full and take in less calories…  A 3500 calorie deficit will lead to one pound of weight loss.

Whole grains, including some breakfast cereals (bran flakes and shredded wheat), brown rice, barley, bran, bulgur, and oatmeal, actually help keep blood sugar levels steady, helping to reduce the risk of metabolic syndrome, which is associated with pro-inflammatory markers in the body. Several large studies have also shown that intake of whole grains, as opposed to refined grains, is inversely associated with weight gain and body fat distribution.

Whole-grain foods are high in fiber and water content. It is thought that whole grains may protect against weight gain through several mechanisms that involve effects on satiety (feeling of being full), glucose and insulin responses, and antioxidant properties.
