Can mobile apps help people lose 

weight...and keep it off?

Many of us may be well accustomed to using health and fitness mobile apps that have the sole purpose of counting calories and measuring activity levels, to help us lose weight. With the majority of people now using Androids and iPhones, downloading apps to our mobile phones is easy and hugely popular. As a result, tracking what we consume on a daily basis has never been so simple. 

However, how effective are these calorie counting apps? Can technology really aid us in reaching our ideal weight, or is it just a fad, a fashion accessory that will be forgotten with the next diet fix?  Furthermore, as with all successful weight loss, does it come down to our own behaviour and self motivation to bring about healthy changes to our life?

A recent study from the Northwestern University Feinberg School of Medicine, identified as the first of its kind, sought to examine the relationship between technology and the impact it had on weight. The study will be published in the Archives of Internal Medicine. 

The Study and Findings

The Northwestern technology research incorporated behaviour change techniques, including self monitoring, goal setting, feedback and social support.

The research examined a cohort of sixty nine overweight and obese men who were an average age of fifty eight. All participants were offered health education classes on nutrition, exercise and behaviour change; every two weeks during the first six months and once monthly for the remainder of the year. 

Each participant received personalised weekly calorie and activity goals to help them lose weight and all participants were encouraged to attend nutrition and health classes. The participants were divided into two groups. One half recorded their activity and diet on paper, whilst the other half used the Northwestern technology mobile device, to transmit their data to a behaviour coach, who monitored and provided feedback twice a month. 

From the evidence, it was found that those who used the mobile device and attended eighty percent of the nutrition classes lost fifteen pounds and maintained this for one year. The weight loss for those who used the mobile app but who did not attend any classes lost almost nine pounds. The group who attended classes but did not use the mobile app, did not loose any weight. 

The lead investigator of the study and Professor at the University, Bonnie Spring, found the results to be positive and argued that mobile devises could have a significant role to play in making people more health aware; "The app is important because it helps people regulate their behaviour, which is really hard to do....Most of us have no idea how many calories we consume and how much physical activity we get. The app gives you feedback on this and helps you make smart decisions in the moment." 

However, Spring also emphasised that weight loss only occurred when people attended health education classes and engaged in regular exercise. The app alone would not be effective.

"The 'widget' is critical but it is not magical by itself," Spring added. "People need all the tools at their disposal." 

Should we all be downloading apps?

Diets usually fail because we end up eliminating certain food groups – and in the long term this is not sustainable. The difference between “diet fads” and calorie counting mobile apps, is that the latter can help set achievable and realistic goals, whilst simultaneously tracking our calorie intake and activity levels. 

It is often the case that we do not realise how many calories certain foods contain, and so, we are ignorant to all the hidden fats/sugars.  Thus, these quick and easy food tracking devices empower us to make sensible and more informed decisions that govern our health and weight. 

A frequent user of a calorie counting mobile app, Koorosh Ashrafi, PhD Research Scientist at BTG International group company, says; “I’ve lost 10 kilos over the past 6 months, and you learn balance is the key.  I’ve lived quite a sedentary lifestyle because of the pressure of work and studying, and I was still consuming the same amount of calories as 10 years ago when I was training as a rugby player.  Although I am a firm believer of everything in moderation, having a device at the tip of your fingertips, really does educate you about food and its content”

Nelly Araujo, Development Administrator at RSPH, and previous user of the mobile app says; “The goal setting was a motivational tool for me, but I found doing the mobile exercise with my partner, is what also drove me to make healthy changes – because we could support and encourage each other”

Bringing about behaviour changes in our life is no easy task.  We have to want to do it and it helps if we have the right tools at our disposal along with a good support network.

Spring believes that one of the big challenges in treating obesity is the need to provide behavioural treatment in a healthcare system where professionals don’t often have the time and training to support people with unhealthy diets or mental problems.

The RSPH is a strong advocator of the benefits of making healthier behavioural changes, but acknowledges that for many this can be challenging. The RSPH Level 2 Awards in Understanding Behaviour Change, is a qualification aimed at helping learners, health trainers and anyone working within the community to engage with individuals to develop strategies to undergo behaviour change and to offer brief advice and interventions to support individuals in improving their health and wellbeing.  Please click here for further information on the qualification, or contact Gina Mohajer.
