USA – DuPont Nutrition& Health latest research study demonstrates that incorporating protein in an energy-restricted diet is important in successful weight loss and maintenance.
A clinical study carried out by researchers from the University of Colorado Anschutz Medical Campus in collaboration with DuPont’s nutrition division showed that including high-protein source like soy protein would lead to significant loss of body fat, an ultimate goal in weight loss.
Since losing weight is never easy and keeping the weight off over time has proved quite challenging, consumers are ditching dieting mechanism for health and wellness in their selection of food products.
The study, published in in the June edition of Obesity Science & Practice involved incorporating soy protein in a 4-month, energy restricted weight loss intervention followed by an additional 8-month weight maintenance phase and evaluation of its effectiveness.
The trial utilized food developed by DuPont, contained 20g of lean, high quality soy protein per serving, delivered in form of a dry-blended beverage, a lean, meat-free, sausage-like soy patty and a nutrition bar.
It was found out that soy-protein was effective in weight loss compared to other sources of protein, in adults with overweight and obesity.
Based on the results, both groups subjected to the study lost similar and significant amounts of body weight attributable to loss of fat.
While both groups lost an average of 3-4% body fat or over 6 kg of total fat loss during higher protein energy-restricted weight loss phase, the participants maintained 4 kg fat loss through the end of the yearlong intervention.
With the study, it was concluded that consumption of foods high in soy protein is critical in weight loss strategy as it supports lean mass and fat loss as well as maintaining the losses.
“Protein is an important part of a weight loss diet,” said Ratna Mukherjea, technical fellow with DuPont Nutrition & Health.
“Lean sources of high quality protein, such as soy, support improvements in body composition with greater loss of fat tissue versus lean tissue.”
This is supported by previous studies which have shown soy-protein containing diets can support long-term health, at the same time mitigating risk factors associated with cardiovascular disease.
“A major take home message from this study is that people following a plant-inclusive or plant-based high protein diet can be successful in reducing body weight,” said James O Hill, Ph.D., a leader in weight loss research and the study’s senior author.
“This study was more about long-term wellness associated with weight reduction. A major struggle for dieters is maintaining their new weight and all the health benefits that accompany weight loss over time.”
Soy protein has been shown to having health benefits as a source of lean, cholesterol-free and lactose-free protein.
The new findings are helpful in a world where consumer preferences are changing especially dieters who choose to follow dietary advice to increase consumption of plant sources or a lean towards flexitarian or vegetarian patterns.
