Increasing your fiber intake can help an indivdual lose weight by the simple properties of intact fibers. For example different fibers, like insoluble fibers can help increase the transit time of food through your digestive system and lesson the absorbability of nutrients. In a study done by Adam et al on male mice they concluded that “increasing amounts of the soluble fermentable fibre pectin in the diet proportionately decreased food intake, body weight gain and body fat content” (1). This particular study also looked at the different satiety hormone levels, PPY and GLP-1, that increased as soluble fiber increased, concluding that hormones play a vital role in maintaining our body weight and metabolism. In another study done by Moreno et al they found that individuals in a cohert study had a lower prevalence of metabolic syndrome when their fiber intake increased (2).
Incorporating more fiber into your diet can also make you feel fuller longer so over eating is decreased. Eating a balanced breakfast with whole grains, fruits, nuts, legumes or complex carbohydrates, in comparison to simple carbohydrates like a doughnut can help lengthen your satiety. To maintain a healthy body weight I would recommend eating a variety of foods with dietary fiber as not all fibers are created equal. In an article posted by eatright.org they recommended fiber for weight loss because “foods rich in fiber such as whole fruits, vegetables, beans and whole grains tend to offer plenty of vitamins and minerals without plenty of calories” (3).
