The prevalence of obesity is increasing worldwide. Portion size is known to be an important determinant of energy intake. However, to our knowledge, no clinical trials have previously been conducted which examine the efficacy of a food portion control tool to control caloric intake and thereby induce weight loss.
Most cases of type 2 diabetes can be attributed directly to obesity. Dietary caloric restriction has been shown to improve glycemic control by virtue of weight loss, with an additional benefit independent of weight loss.
Comparison: daily use of a food portion control tool plus usual care at a diabetes care center, compared to usual care alone.
