Unhealthy dieting leads to higher weight in teens, study says

1. The study researched how consisted dieting and unhealthy weight control behaviors (smoking cigarettes, vomiting, usage of laxatives, etc.) during teen years ultimately ended in an increase in BMI across the board as opposed to those who did not diet.

2. The University of Minnesota's Institutional Review Board Human Subjects Committee completely approved of the Project EAT (Eating and Activity in Teens and Young Adults) study.

3. The sponsor of this project was interested in knowing whether or not those who dieted would “benefit” by not over eating and keeping down weight, or if dieting and other unhealthy behaviors that were practiced in a casual matter, along with binge eating during certain periods, ended up hurting more than helping.

4. The methodology involved included a study conducted in 3 waves of surveys. The first in ’98-99, then ’03-04 and finally ’08-’09. The study was conducted on residents of metro Minneapolis, 1,902 people (who responded at all three times; 819 males and 1,083 females). The surveys asked questions involving what methods of dieting each individual used, how often did they diet from “Never” to “>10 a year,” took measured the participant’s BMI in the first wave and the majority self-reported their BMI during the final wave.

5. The results are shown in a clear manner. Those who dieted more and conducted in unhealthy weight control behaviors ended up gaining a higher BMI over the 10 year time span as opposed to those who didn’t diet or opted out for healthier lifestyle changes.

6. The graphs are broken down in a very clear and concise manner. Everything is explained and there are footnotes that go with all the graphs.
