Slow release, low glycemic carbohydrate supports weight management, says a recent study

January 24, 2020

A study recently published in Nutrients1 shows that isomaltulose, a slow release, low glycemic carbohydrate called Palatinose from Beneo (Mannheim, Germany), supports additional weight loss and fat mass in overweight and obese adults, when replacing sucrose. In the randomized, double-blind, controlled study, 50 healthy overweight and obese adults were given either 40 g of Palatinose or sucrose over four meals per day as part of an energy-reduced diet. Changes in body weight, body composition (fat mass, fat free mass), and energy metabolism were assessed at baseline and every subsequent four weeks.

Results showed that while both the isomaltulose and sucrose groups experienced significant reductions in body weight, the most of which occurred during baseline and week 4, the isomaltulose group showed a significantly faster rate of weight loss, despite a decreased mean rate of weight loss after week 4. Compared to baseline, subjects in the isomaltulose group showed a significantly higher percentage of free fat mass, also known as lean body mass, than the sucrose group. The isomaltulose group also showed a significantly higher reduction of fat mass than the sucrose group.

“This study clearly shows that carbohydrate choice matters when undertaking a weight loss diet. Using Palatinose instead of sucrose supports weight loss and the reduction of body fat in overweight and obese people, because it steers the metabolism towards fat burning,” said Anke Sentko, vice president of regulatory affairs and nutrition communication for Beneo, in a press release. “With 670 million adults worldwide now registered as obese, this is an important step towards looking beyond calorie counting and considering instead what people can eat to help them better achieve their weight loss goals.”
