About Intermittent Fasting(IF) 

Intermittent fasting (IF) is currently one of the world’s most popular health and fitness trends. People are using it to lose weight, improve their health and simplify their lifestyles. (IF) is an eating pattern that cycles between periods of fasting and eating. It doesn’t specify which foods you should eat but rather when you should eat them. In this respect, it’s not a diet in the conventional sense but more accurately described as an eating pattern.

What is"MyFastingBud"? 

the purpose of this whole exercise was to develop a mobile app concept for helping people who do intermittent fasting. Usually, compliance with any food regiment is the hardest part for people who wanna lose weight. However, the IF community is different from the regular diet industry because there are people within the community who adopted fasting for other reasons such as spirituality and mental health even after they achieved their desired weight . Some of these folks might not be overweight anymore but they continue IF  and they usually like to share their experience and help others who are at the beginning of their fasting journey for weight loss purposes and find it hard to conform with  IF.  If there is an app to connect these groups together, the former can be acted as a powerful support system for the latter.

  • Problem Scenario

1.0 Brainstorm Personas 

In this stage the intent was brainstorming as many personas as I could who are related to the area of interest in the following format: a descriptive name: [Made up Name] the [Job title or role]. After brainstorming, I sorted the personas in order of priority. This stage was to clarify if we could only pitch the idea to one persona, which would it be? Finally, a quick note was added on why the persona was prioritized.

1.1 Make the Persona Testable & Actionable with a Screener 

A good persona is vivid and testable. An effective way to make sure you’re there is to have a screener. This is (ideally) one or two questions with discrete answers where with a simple response so we can qualify or disqualify a subject (individual) as representative of our persona (or not).  For the top persona selected in the table above (Mike), I created a screener. The intent was not trying to sell them anything or convince them of anything- the screener was for research purposes and just a way to assess whether they’re representative of my selected persona.

With this particular persona, we want to make sure the individual has substantive experience with intermittent fasting that led to great weight loss results. Also, we need to screen out, for example, health enthusiasts that are well-familiar with fasting and do an occasional fasting method.

2.0 Positioning Statement  

For [people trying to manage their weight and health by adopting Intermittent Fasting (IF) into their daily life] who [often find it hard to comply with a consistent fasting schedule and need support to stay motivated],  [MyFastingBud] is a [mobile app] that [provides an interactive platform helping users follow a collective fasting schedule and stay motivated]. Unlike [other IF management apps such as ZERO], our product [focuses on the social exchange through collective efforts, experience sharing, and healthy competition to achieve weight loss].

3.0 Develop Problem Scenario, Alternatives, Proposition Trios  

This stage started by thinking about what’s actually important to my personas, how they’re doing that now, and how you might improve it. For my top persona picked in the list above, I thought about the top problem scenarios/jobs-to-be-done, along with their current alternatives and more importantly the value proposition that “MyFastingBud” can offer.
