Yellow pea fiber, body fat and energy intake in overweight adults

What it found

Taking 15 g of yellow pea fiber daily for 12 weeks led to small losses in body weight and fat in overweight adults.

The fiber group also ate less at a test meal and had lower blood sugar responses.

What they found

Studies in people

Body weight and fat

The pea fiber group lost 0.87 kg of body weight over 12 weeks, mostly from losing 0.74 kg of body fat. The placebo group gained 0.40 kg.

Energy eaten at lunch

At the follow-up buffet lunch, the pea fiber group ate 16% less energy than before. The placebo group did not change how much they ate.

Blood sugar response

During a sugar tolerance test, blood sugar levels were lower in the pea fiber group at the end of the study. Insulin rose in both groups but increased more in the placebo group, by 38% compared to 10% in the fiber group.

Gut bacteria

Researchers found no differences in gut bacteria between the two groups after 12 weeks.

What the authors conclude

  • They suggest that adding 15 g of yellow pea fiber each day may bring small but meaningful metabolic benefits. They say this could help manage obesity even without other lifestyle changes.

How it was done

The authors wanted to see how yellow pea fiber affects body makeup and metabolic markers in overweight or obese adults.

Fifty adults (9 men and 41 women) with an average age of 44 years took part. They ate wafers containing either 15 g of pea fiber or a placebo every day for 12 weeks. Researchers measured body composition, blood sugar responses, food intake at a buffet lunch, and gut bacteria.

What it can’t tell you

  • We summarised it from the abstract only.
  • This trial lasted only 12 weeks, so it cannot show what happens over longer periods. The group included 9 men and 41 women, so results might differ in a more balanced mix of people.
