The peer-reviewed article titled, ‘Physical Activity and Quality of Life in Severely Obese Adults during a Two-Year Lifestyle Intervention Programme,' was written by Randi Jepsen, Eivind Aadland, Lesley Robertson, Ronette Kolotkin, John Andersen, and Gerd Natvig. The article was published in 2015 by Hindawi Publication Corporation. The authors argue that it remains unknown how the quality of life is affected by the changes in physical activity during lifestyle interventions among individuals suffering from obesity (Jepsen et al., 2015). This research aims at examining the relation between the adoption of positive life interventions and the alteration that ensues in the quality of life among individuals with obesity over a period of two years.

The research problem in this study builds an effective persuasive argument considering the increasing difficulties and awareness surrounding obesity. The problem statement is easily located at the end of the introduction; it focuses on the relationship between the self-sufficient and reliant variables used in the study.
