Review: Eating High-Fiber Foods Is One of the Best Ways to Lose Weight
01 Apr 2016 --- New research confirms that eating a steady diet of beans, peas and lentils may help you lose weight – and keep it off.
A new study published in The American Journal of Clinical Nutrition demonstrates how one daily serving (about 3/4 cup, or 130 grams) of beans, peas, chickpeas, or lentils has the potential to keep dieters feeling fuller, longer. Researchers concluded that an enormous 90 percent of weight loss interventions fail, and hunger and food cravings may be partly to blame. That makes the ability to stave off hunger a target to hit for successful dieting.
For the study, researchers examined 21 clinical trials that included a total of 940 adult men and women. Data from each study was pooled and averaged out to figure out how, over the course of six weeks, each participant’s weight changed after they followed a diet which included a daily single serving of beans, peas, chickpeas, or lentils, also known as “pulses.”
Without changing any other aspect of their diet or physical activity routine, the participants were able to lose just an average of 0.34 kg (0.75 pounds) in weight.

The research, conducted by a team from St. Michael’s Hospital in Canada, builds on previous work that found a daily serving of pulses helps people control their weight and significantly reduce ‘bad cholesterol’ levels by five percent - therefore lower the risk of cardiovascular disease.
"Despite their known health benefits, only 13 percent of Canadians eat pulses on any given day and most do not eat the full serving," said Dr. Russell de Souza, lead author and researcher at St. Michael’s Hospital, in a press release. "So there is room for most of us to incorporate dietary pulses in our diet and realize potential weight management benefits. Pulses increased the feeling of fullness by 31 percent, which may indeed result in less food intake."
Both the United Nations and the Food and Agriculture Organization have designated 2016 as the International Year of Pulses.
Pulses have a low glycemic index (GI), which means they break down and convert into energy for the bloodstream slowly, keeping hunger at bay. Foods that break down quickly, such as pineapple or macaroni and cheese, have a high GI and give you a jolt of fleeting energy. Feeling full helps keep the body from giving into impulsive cravings.
According to the Mayo Clinic, eating energy-dense, high-fiber foods can help with weight loss and beans are one of the healthiest choices because they’re also low in both fat and calories.
In another study published in 2015, a team of researchers from the University of Minnesota found that beans were also ideal for those trying to cut down on meat or switch over to a vegetarian diet altogether. The scientists fed participants two different lunches at random — one meatloaf primarily made from beef and a second one made primarily of beans.
While the meat provided 26 grams of protein and 3 grams of fiber, the bean loaf delivered 17 grams of protein but with 12 grams of fiber. Afterwards, researchers found that both groups of participants felt equally full. The fiber helps suppress appetite by slowing down the digestive process, which also aids in controlling blood sugar levels.
De Souza concluded: "Though the weight loss was small, our findings suggest that simply including pulses in your diet may help you lose weight, and we think more importantly, prevent you from gaining it back after you lose it.”
