Fiber-based Ingredient Can Make You Eat Less

Consumers need healthy foods that will help them control their appetite. (Source: University of Liverpool)Scientists from the University of Liverpool have demonstrated the effectiveness of a fiber-based dietary ingredient that makes people feel less hungry and consume less food.
 
Hunger is a major barrier to successful weight control and consumers need healthy foods that will help them control their appetite. Although fibers have the potential to modulate appetite without adding additional calories, they can make foods less appealing. Moreover, most studies employing fibers have failed to demonstrate positive effects on either appetite or food intake, and certainly no effects lasting the full day.
 
Feeling fuller
 
Psychologists from the University’s Institute of Psychology, Health and Society tested whether the new product (Weightain satiety ingredient), consisting of a combination of dietary fiber sources including a viscous hydrocolloid and a whole-grain corn flour rich in resistant starch, made people feel fuller for longer and influenced the amount of food they ate.
 
In the study, 90 normal to overweight participants were given a fruit-based smoothie for breakfast containing a dose of either 20 or 30g of the satiety ingredient, or a non-active control. Their subsequent intake of food at both lunch and dinner on that day was measured and their levels of hunger examined.
 
The study found that food intake at both lunch and dinner times was lower when the satiety ingredient was given at breakfast, compared to the control. Overall, after the 20g dose, 4 percent fewer calories were eaten and after the 30g dose 5 percent less food was eaten at both lunch and dinner combined.
 
At lunchtime, 5 percent less food was consumed after the 20g dose than after the control. At dinner time participants ate 7 percent fewer calories after the 30g dose compared to when they had the smoothie made without the Weightain satiety ingredient.
 
Lower hunger levels after breakfast were recorded for both doses and the 30g dose produced lower hunger levels after lunch.
 
Controlling hunger
 
“This is the first study to examine the short term effect of this particular combination of fibers on appetite and food intake," said Dr. Jo Harrold a psychologist from the University’s Human Ingestive Behavior Laboratory in the Institute of Psychology, Health and Society. “Whilst more research is needed to measure these effects of the product over longer periods of time and in people who are actively trying to lose weight, this study demonstrates high fiber food products which make you feel fuller could provide a potential solution to weight management.”
 
Professor Jason Halford, also a psychologist, added: “What is notable is this product, given with breakfast, produced effects on appetite, which were apparent across the day. This is important when consumers are seeking help controlling they hunger across the day.”
