A recent study conducted at the University of Illinois Urbana-Champaign has revealed key factors that contribute to successful weight loss among participants in a self-directed dietary education program. The study, published in Obesity Science and Practice, found that individuals who consumed higher amounts of protein and fiber, while also personalizing their plans and maintaining flexibility, achieved the greatest success at losing weight over a 25-month period.
Participants in the Individualized Diet Improvement Program (iDip) were able to lose an impressive 12.9% of their body weight at the one-year mark, compared to the rest of the study sample who only lost slightly over 2% of their starting weight. This highlights the effectiveness of personalized and flexible programs in supporting long-term weight loss goals.
Led by Professor Manabu T. Nakamura, the iDip program utilizes data visualization tools and intensive dietary education sessions to help participants increase their knowledge of key nutrients and develop a personalized weight-loss plan. Increasing protein and fiber consumption, along with consuming 1,500 calories or less daily, are the pillars of the iDip approach.
The study also emphasized the importance of preserving lean body mass during weight loss, especially when using weight-loss medications. It was found that increasing protein intake helps to prevent muscle and bone loss while losing weight, reducing the risk of side effects associated with certain weight loss drugs.
Overall, the research suggests that sustainable dietary changes, tailored to individual needs, are essential for achieving and maintaining a healthy weight. The findings of this study provide valuable insights into effective strategies for successful weight loss and long-term weight management.
