Some miracle fiber and weight loss products tout that dietary fiber can trap or kill fat cells. There is no medical evidence that this is true, but dietary fiber does have lots of health benefits.
Fiber and weight loss may go hand in hand because dietary fiber is filling and may cause you to eat less. However, studies have found that fiber does little more than that. People wanting to lose weight should be wary of fiber and diet products that promise dramatic results.
It Almost all dietary fiber comes from legumes, fruits, green leafy vegetables, whole grains and bran. High fiber foods, especially fresh fruits and vegetables, are low in calories. You can eat more of these foods without adding a lot of calories.
Fiber and weight loss are important together. The fiber found in fruits and vegetables, called soluble, absorbbs water as it moves through your digestive system, making you feel full. Insoluble fiber does not hold water or dissolve. It is associated with "roughage." Insoluble fiber aids digestion and helps promote regularity. Nutrition experts say people trying to improve their diets should include 20 to 30 grams of fiber every day.
Fiber and weight loss are both great for diabetics who are trying to preserve their help and stop the need to be insulin dependent. Some studies have found that fiber may improve blood sugar levels, reduce the need for insulin and allow some diabetics to be better able to control their blood sugar with their diet.
