Eating one serving of dietary pulses — peas, lentils, and beans — increases fullness, and can lead to better weight loss and management for patients, according to researchers.
“Dietary pulses, defined by the Food and Agriculture Organization as non-oilseed legumes harvested solely for their dry grain, are high in fiber and protein and low in glycemic index — properties which have been shown to reduce appetite and acute food intake,” explained Siying S. Li, of the University of Toronto in Obesity.
In order to access the effect of dietary pulses on acute satiety and second meal intake, the investigators conducted a systematic review and meta-analysis of 126 patients.

Dietary pulses produced a 31% greater satiety incremental area under the curve (RoM=1.31; 95% CI: 1.09-1.58; P=0.004) without effecting second meal intake compared with a control diet, according to the researchers.
“Although this increase in satiety does not manifest in a detectable decrease in second meal food intake, it may nevertheless explain some of the long-term weight loss benefits associated with dietary pulse consumption by supporting adherence to weight loss diets,” concluded the researchers.
