Pilot Trial of "My Meal Mate" (MMM), a Smartphone Application for Weight Loss

December 6, 2012 updated by: Michelle Carter, University of Leeds

Pilot Trial of "My Meal Mate" (MMM), a Smartphone Application Designed to Facilitate Weight Loss.

The aim of this study is to implement an exploratory pilot trial of "My Meal Mate" (MMM), a smartphone application developed to facilitate weight loss, assessing its feasibility and acceptability. Overweight and obese adults will be recruited from large employers within the local area. The trial will aim to recruit a sample size of 135 which is a pragmatic decision based on randomizing 45 people to each arm. Participants will be randomized to one of three groups. The researchers have developed a smartphone application for weight loss called "My Meal Mate" (MMM) which incorporates a large branded food and drink database. MMM was developed using focus group data collected from potential system users and by benchmarking with similar commercially available diet tracking applications. One group will receive a smartphone with the MMM app downloaded on it, one group will receive access to an online food diary and one group will be given a paper food diary. Participants will be asked to set a goal for weight loss and self-monitor their food intake and activity using their allocated study equipment. Participants will be weighed at the beginning of the trial, at 6 weeks and at 6 months. Feasibility and acceptability outcomes will be assessed.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Paper food diary
Behavioral: Paper food diary
The paper food diary is provided by a commerical slimming organisation called "Weight Loss Resources". The diary allows the user to record daily food and drink consumed. It is accompanied by a book which provides a database of the nutritional content of 40,000 food and drinks. The diary also encourages participants to record their physical activity.
Active Comparator: Online food diary
Behavioral: Online food diary
The online food diary is provided by a commerical slimming organisation called "Weight Loss Resources". The electronic diary allows the user to record daily food and drink consumed. System users are also encouraged to record their physical activity.
Experimental: "My Meal Mate" (smartphone application)
A smartphone application called "My Meal Mate" (MMM) designed to facilitate weight loss. The app allows system users to set a goal for weight loss and self monitor diet and activity in an electronic diary. Users can select foods from the large "Weight Loss Resources" food database. Instant nutritional feedback is provided along with weekly feedback by text message.
Behavioral: "My Meal Mate" (smartphone application)
A smartphone application called "My Meal Mate" (MMM) designed to facilitate weight loss. The app allows system users to set a goal for weight loss and self monitor diet and activity in an electronic diary. Users receive instant nutritional feedback and feedback via text message.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Adherence to the trial
Time Frame: 6 months
The number of completers in each group is a feasibility outcome.
6 months
Adherence to the intervention arms
Time Frame: 6 months
The number of days with a plausible record of diet (>500-5000 kcal recorded) in each arm is a feasibility outcome.
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Weight change (kg)
Time Frame: 6 months
Weight (kg) has been objectively measured at baseline and 6 months.
