With the introduction of new personal tools like
smartphones, several studies have shown that the
use of apps that help users to self-monitor their diet,
increased the user’s awareness about the food
intake, allowing them to lose more weight than with
other procedures [2,3]. Furthermore, a study from
the George Washington University in collaboration
with the Department of Community and Family
Medicine and Psychology and Neuroscience from
Duke University, assessed 204 apps that help users
lose weight. The apps were qualified according to
13 practices that engaged and help users to lose,
track and control their weight [4]. The study
revealed that less than 15% of the apps contained
more than 5 of the practices, leaving an open door
for interesting improvements in terms of usability
and reliability in diet apps [4]. According to practices
of this study, MFP scored 7 out of 13, placing this
app in the category of most comprehensive [4]. The
practices that MFP contains are: Keeping a food
diary, maintain a calorie balance between in vs. out,
a weight loss goal of 1 to 2 lb. a week, having a
portion control, tracking weight, keeping a physical
activity journal and seeking social support.
Disregarding other practices like suggesting drink
water instead of sodas, or recommending a rich,
balance diet with vegetables and fruits
