22 Aug 2024 --- Participants in a dietary education program who lost the most weight in a one-year program consumed higher amounts of protein and fiber, according to a recent study. Within this group, 41% of all 22 participants lost 12.9% of their body weight after a year, while unsuccessful dieters lost slightly over 2%. The researchers say this underscores the importance of personalized, flexible programs to help dieters adhere to their plans.
