The objective is to compare the effectiveness of a 1-year digital dietary intervention on body weight reduction and improved diet quality, in adults living with obesity delivered by dietitians in a primary care setting, with a control group.
The chat2 (Connecting Health and Technology 2) study is a 1-year randomized controlled trial (RCT). Consenting participants will be randomly assigned (1:1) to an intervention or minimal intervention control group.

This study is a 2-arm randomized controlled trial with a 3-month follow-up. Participants will complete a questionnaire at baseline, immediately after the intervention, and 3 months after the intervention. Participants will express their interest to participate in the study through a Qualtrics survey. Informed consent will be obtained at the start of this survey. Following this initial survey, dietitians will be randomized in blocks of 4 into either the intervention or a waitlist control condition (1:1).

AMPM is a web-based interface designed for surveillance, typically implemented in-person by a trained interviewer, which adds to the cost of undertaking large-scale surveys. The AMPM provides a structured interview format with specific probes in 5 structured sets or passes: a quick list, forgotten foods pass, time and occasion pass, detail pass, and final review [10]. Portion size estimation is addressed using a food model booklet.

In “Improving Nutrition and Activity Behaviors Using Digital Technology and Tailored Feedback: Protocol for the Tailored Diet and Activity (To DAy) Randomized Controlled Trial” (JMIR Res Protoc 2019;8(2):e12782), corrections have been made to the article title and to three places in the text to reflect that the term “Live Lighter” is a registered trademark.

Design and Development of a Digital Weight Management Intervention (ToDAy): Qualitative Study
The advertisements also direct people to a campaign website where there is an option to enroll on the web to access a meal planner, recipes, and weight-monitoring tools and to receive update emails. The Tailored Diet and Activity (To DAy) study
aims to build a digital intervention that provides individualized tailored feedback on dietary and activity behaviors.

In Australia, young adults (aged 18-24 years) are gaining weight and at a faster rate than any other adult age group [1,2], with 31.5% [3] affected by overweight or obesity. Studies report weight gain of around 0.5 kg to 1 kg (1-2 lbs) per year over a 5- to 10-year period in young adults [4-6]. Becoming overweight or obese at a young age increases the risk of noncommunicable chronic diseases, including metabolic syndrome, type 2 diabetes, cardiovascular disease, and specific cancers [7].

Kornman et al [7] described only a modest level of adolescent engagement with their text messaging and email adjunct to the Loozit program, with adolescents responding to 22.0% of text messages over a 10-month maintenance period. The authors found that text messages asking for a response had more replies and text messages had a more immediate response than the emails. Whether text messaging can be used to maintain engagement of overweight adolescents in a healthy lifestyle program remains unclear.

As a result of these limitations, early investigators concluded that the technology was a barrier to collecting accurate information.
However, with the rapid advancement in the capabilities of mobile devices, researchers are now pursuing image-based methods as a way of addressing the limitations of traditional dietary assessment methods [21-23].
