ABSTRACT

Most people are very concerned about what they eat every day. This is because they

tend to find information about what they eat or what is related to diet. But they do not

know how to take the right foods for the diet. Diet is the amount of food needed by

someone, which is a nutrient intake of foods such as protein, carbohydrates, fat,

vitamins, mineral salts, water and salts in the quantities required by their body.

Nowadays, there are many systems that can help people to managing their diet.

However, the system does not focus on user requirements. Some people need nutrition

and dietary requirements vary by weight, age, height and so on. Therefore, we provide

this system to facilitate food intake according to the type of weight, activity level and

so on because every weight requires a different quantity and manner in terms of

exercise. They need something that will help them with the needs of their respective

bodies. The application to be developed is Food Intake For Diet (FIFD). This

application will help and facilitate affairs for people who want to lose weight correctly.

For example, how to eat foods according to the correct quality, the required water

content, and so on. The production of this project for the moment reminds users what

to do and what to do not do. In this system there is a type of diet where consumers can

choose to use the kind of diet they like. Therefore, this application method is

implemented in the system to generate the correct diet plan and health guidelines.

ABSTRAK

Kebanyakan orang sangat mengambil berat tentang apa yang mereka makan setiap hari.

Hal ini adalah kerana mereka cenderung untuk mencari maklumat tentang apa yang

mereka makan atau apa yang berkaitan dengan diet. Tetapi mereka tidak tahu cara untuk

mengambil makanan yang betul untuk diet. Diet ialah jumlah makanan yang diperlukan

oleh seseorng iaitu pengambilan makanan yang mengandungi nutrient seperti protein,

karbohidrat, lemak, vitamin, garam mineral, air dan pelawas dalam kuantiti yang

diperlukan mengikut tubuh mereka. Pada masa kini, terdapat banyak sistem yang boleh

membantu manusia untuk menguruskan diet mereka. Walau bagaimanapun, sistem

tersebut tidak menumpukan kepada keperluan pengguna. Sesetengah manusia

memerlukan nutrisi dan keperluan diet yang berbeza mengikut berat, umur, ketinggian

dan sebagainya. Oleh itu,kami menyediakan sistem ini bagi memudahkan pengambilan

makanan mengikut jenis berat, tahap aktiviti dan sebagainya kerana setiap berat badan

memerlukan kuantiti dan cara yang berbeza dari segi senaman. Mereka memerlukan

sesuatu yang akan membantu mereka dengan keperluan badan masing-masing.

Applikasi yang akan dibangunkan ialah Food Intake For Diet (FIFD). Applikasi ini akan

membantu dan memudahkan urusan bagi orang yang ingin mengurangkan berat badan

secara betul. Sebagai contoh cara pengambilan makanan mengikut kuntiti yang betul,

kadar air yang diperlukan dan sebagainya. Penghasilan projek ini untuk sentiasan

mengingatkan pengguna apa yang perlu diambil dan apa yang perlu dilakukan. Dalam

sistem ini terdapat jenis diet dimana pengguna boleh memilih untuk menggunakan jenis

diet yang mereka suka. Oleh itu, kaedah applikasi ini dilaksanakan dalam sistem untuk

menjana pelan diet dan garis panduan kesihatan yang betul.

CHAPTER 1

INTRODUCTION

1.0 Introduction

People at this time are very concerned about their health and nutrition. Most of

them are dieting, but are not good at choosing the right nutrition. A healthy diet is

a healthy eating habits. A good diet is a balanced diet that meets all the needs of

the body, such as foods that contain nutrients such as proteins, carbohydrates, fats,

vitamins, mineral salts, water and salts in the quantities required. Malaysia is one

of the countries that have dietary issues because they have a lot of obesity.

Malaysia is the first of ASEAN and sixth in the Asia-Pacific region.

2

Diet is an important part of our daily lives. Applying a diet can mean making some

good choices about nutrition (eating more fruits, vegetables, and fiber) or bad

choices (skipping food, eating too little or not eating enough food). Diet is the

amount of food used by a person in a certain amount. Diet often implies the use of

specific nutrition for health or the reason for weight management. A specific diet

can be selected for weight loss or weight gain. Some foods are specifically

recommended or altered for compliance with pertinent dietary requirements. Diet

also has many different types, namely the first Paleo diet. The paleo diet is a diet

with no rice, processed foods, sugars, dairy and cereals. Second, diet atkins is a

diet that only consumes foods containing protein and fat, and avoids foods

containing carbohydrates. Third, a vegetarian diet is a diet that only eat fruits and

vegetables only at the right rate. Fourth, raw food diet ie food and beverages not

processed or cooked ie based on plants and organic matter.

The diet should also follow the proper syllabus because different people will have

different dietary nutrition requirements based on their weight, age, height, gender

and daily activity. For example, having two dieters using atkins diet and weighing

weight, people weighing 60 and weighing 140, the system will set the appropriate

rates and quantities according to their weight. Therefore, we recommend this

system to help those who want to diet in the right way.

3

1.1. Background System

Food Intake For Diet (FIFD) is an application system. It is responsible for

developing a diet plan and dietary health guidelines for people who want to lose

weight using the right method. FIFD has worked together to help people who

want to lose weight reduce the number of obesity in Malaysia.

FIFD is a system that can help users to manage their daily diet or food intake

appropriate for their body needs according to proper syllabus. This system is one

of the effective alternatives to reducing heavy lose and changing lifestyles that

benefit the public in various ways. Diet menu plans are generated based on the

user's health state, which is the level of dietary level, and body mass index (BMI).

Consumers will choose which diet they want to use. For example, using the Atkins

diet method. Therefore, it will help the user to take what kind of food dishes are

appropriate for them and always remind the user. It is easier for users to plan their

daily diet better.

This system is developed using PHP and HTML for web development and

MySQL as a database platform and we use Flash, 2D and 3D to increase

animation. This system is based on rules for producing diet plans and dietary

guidelines for Diet.

4

1.2. Problem Statement

People at this time are very concerned about their health but they are unaware that

good food intake will provide good health. They are less concerned about what

they eat. However, there are some problems, most of whom are less aware of how

to choose and the type of food that is suitable for their body. This is because

different people will have different dietary requirements. For example, some

people like to use the vegetarian diet because he only wants to eat vegetables and

fruits and think because by eating vegetables it can lose weight quickly. The

amount of food intake should be according to the weight and the body needs to

have enough protein for the body. The right way to take food should also look at

the type of age, weight, height, gender and lifestyle first.

In this modern age, people live in a busy and always on the go. So, some of them

do not have time to make details about what they need to eat. They only eat

without knowing what is actually right for their body and most of them use drugs

to help them lose weight quickly without knowing the effects of the future. And

lastly, many people who want to diet but lose their appetite. Some people, can not

withstand the desire but want to be skinny and because there are some who use

skin peels.

Therefore, we build this system to help those who want to lose weight using food

intake in the right way.

5

1.3. Objectives

Food Objective For Diet Applications is:

- To plan a food intake apps for people who want to lose weight correctly

- To develop an apps that can help reduce the number of obesity in Malaysia

- To implement rule-based rules in Food Acquisition for Diet

1.4. Scopes

The main scope for the apps is:

1. Nutritionist / Admin

Admin has the power to manage, update and delete diet menu data and health

guidelines in the apps

2. User

Users can sign up and login to the apps and perform tasks that are set in the

apps. Users can manage profiles, manage the latest information such as weight

loss, manage health conditions with take through of body, and exercise. Users

can access the system anytime and anywhere. And all user can use this apps

it’s general for all user.

6

1.5. Limitation Of Work

Food Diet for Diet (FIFD) provides dietary recommendations and health

guidelines based on dietary phases, body mass index (BMI) and appropriate level

of activity using android user only. It is designed to help them with diet using the

right foods for those who want to lose weight only. Design for the diet is also

suitable for people who follow the diet. Diet planner consists of a recommended

diet based on the type of diet and health guidelines that are suitable for those who

need to lose weight but user that making decision that cannot be determined.

1.6. Expected Result

- Rules based rules can be implemented on the apps

- The relationship between food, activity and carbohydrate intake can be

identified

- An apps that can help and benefit the users in their diet

1.9. Conclusion

The apps is designed to help those who want to lose weight with proper dietary

intake - nutrition - containing foods such as protein, carbohydrates, fats, vitamins,

mineral salts, water and salts in the quantities required. And it's also important to

remind consumers to take the correct dietary content.

In turn, the system is designed to help control obesity rates. The apps is also set

up to balance the intake of food with physical activity and make the physical body

better. And besides it works for a diet, the system also works for the right exercise.

CHAPTER 2

LITERATURE REVIEW

2.0 Introduction

In the literature review we will discuss fulture about Food Intake For Diet mobile

application that contains the definition and previous research of application

problem that comparison of existing system and we will find the solution approach

that apps use.

11

2.1 Application Problem

Application problem in this topic is explain about comparison with another apps

or system that already have and find the weakness to solving the problem while

creating these apps. There are five already existing system information :

1. ‘My Meal Mate’ (MMM)

The purpose of this study was to assess the self-monitoring about dietary and

physical activity.

Strength – The extensive database with generic and branded food items for

people to choose from

Weakness – Must using internet, unattractive design, not understand the button

use

2. Timing of food intake predicts weight loss effectiveness

Timing of food intake influences the success of a weight-loss diet in humans

and to evaluate the role of food timing in weight-loss effectiveness.

Strength – the sample is relative large with numerous exposure variables

including biomarkers and genetic indicators

Weakness - Unattractive design, easily bored, lots of text

12

3. Dietry Self – Monitoring, Improves with use of Smartphone apps

Dietary self-monitoring is linked to improved weight loss success using

smartphone applications (apps) that allow to improved dietary tracking

adherence.

Strength – Smartphones apps, interesting design

Weakness – Graphics, using inappropriate threads

4. Mobile apps Self – Monitoring of physical activity and dietary intake

among overweight adults participating in an Health weight loss program.

Assess the self-monitoring about dietary and physical activity that monitoring

related to changes in self-monitoring frequency, dietary outcomes, energy

expenditure, body mass index (BMI), and body weight.

Strength – Use of validated measures and weekly data collected on both self-

monitoring and adherence to the intervention

Weakness - Lack of information, product quality not top-notch

5. Application of a behavioral Approach to measuring Dietary Change : The

Fat and Fiber – related Diet Behavior Questionnaire

This apps use to provide insight into the process of practicing a healthy diet

with regard to fat and fiber.

Strength - User friendly interface

Weakness - Using lesser colors, lack of information

2.2 Solution Approach

The solution approach describes the general approach that will be taken to create

or acquire the new capabilities required the need. To determine the solution

approach, it is necessary to identify possible approaches, determine the means by

which the solution may be delivered (including the methodology and lifecycle to

be used) and assess whether is capable of implementing and effectively using a

solution. Then the tecnique that we use is Rule-based system (RBS) to remind the

user.

2.2.1 Rule-Based System (RBS)

In computer science, a rule-based system is a set of "if-then" statements that

uses a set of assertions, to which rules on how to act upon those assertions

are created. In software development, rule-based systems can be used to

create software that will provide an answer to a problem in place of a human

expert. These type of system may also be called an expert system. Rule-based

systems are also used in AI (artificial intelligence)programming and systems.

Rule-based system are used to store and manipulate knowledge to interpret

information in a useful way. rule-based system is also known as expert

system and consist of rule base, inference engine, working memory and user

interface as well as a set of if-then statement and rule set containing encoded

knowledge of an expert.

16

Example of coding :

c = Clock ;

Rule 1 :

if (c ”07:30”) {

then “Food Intake For Diet.

Good Morning :) Your Breakfast is waiting … "; }

Rule 2 :

else if (c ”13:00”) {

then “Food Intake For Diet.

Good Evening :) Your Lunch is waiting … "; }

Rule 3 :

else if (c “20:00”) {

then “Food Intake For Diet.

Good Night :) Your Dinner is waiting … "; }

Table 2.2 Show the example coding using Rule-based system for remainder

17

2.3 Conclusion

As the conclusion, there are few research thesis that already been discussed about

system and mobile application that will help more with this project. There are also

application that is more advance but not specific enough for whom are want to loss

weight and diet.

It is easy to apply and fast to read the data. Than we using technique rule-based

system that applied to making this project to popup or remainder to user.

CHAPTER 3

METHODOLOGY

3.0 Introduction

In these chapter, we will describe the methodology concept in system

development. We will explain step by step on developing the systems and how to

develop it. For the Food Intake for Diet, it will be following by step that has been

designed from start until finish and we using ADDIE method.

Addie is an acronym for the five stages of a development process that stand from

Analysis, Design, Development, Implementation, and Evaluation. The ADDIE

model relies on each stage being done in the given order but with a focus on

19

reflection and iteration. The model gives a streamlined, focused approach that

provides feedback for continuous improvement.

Figure 3.1 ADDIE method

1. Analysis

Analysis is a detailed examination of anything complex in order to understand

its nature or to determine its essential features from a thorough study. Before start

developing any content or training strategies, we must analyze the current

situation in terms of training, knowledge gaps and etc. First, start with questions

to understand the current situation and to also understand what is the goal.One

very common question is: What is problem statement? find problem that they

have and face. Then develop the apps to solve problems and adds the advantages

of the function to be better and more attractive. Then find Software and hardware

requirement used to develop the apps

20

2. Design

Design is to create, execute, or construct according to plan (designing and

contrive). With training plan, it is need us to design phase – this is where we take

all of the learnings of the previous phase and use it to make practical decisions.

This includes a strategy, delivery methods, structure, duration, assessment, and

feedback. Then it is to do storyboard ideas and create a prototype like process

design and Interface design for user and admin

3. Development

Development is the act, process, or result of developing after designing the

prototype. Each element of the course should be developed to match the design

phase. To develop the apps we must know how to use script ( java script, php,

html) and which script that we use. Then it must have the element of multimedia

like animation and multimedia component like audio, video, picture and etc.The

development process should be iterative. Once you have created a course you

should test it to ensure there are no basic errors – grammar, spelling, syntax etc.

Testing should also look at the mechanics of the course.

4. Implementation

Implementation is an act or instance of implementing something like the process

of making something active or effective. Once you have completed and you are

satisfied that are fully tested, it’s time to deploy prototype apps to the general

public that this apps exist.The decisions made in the design phase will influence

how this is actually carried out.

21

5. Evaluation

Evaluation is the act or result of evaluating. Getting feedback on every aspect

like test functionalities of developing prototype apps is really important so that

can improve and revise the content. A great way to get feedback is to ask

someone to complete surveys at the end of their course. Create questions specific

to the points above but, also encourage people to give feedback in a free text box

so that you are aware of any gaps you may not have thought of.

22

3.1 Problem Identification

Problem identification is to provide the platform for investigating a broad range of

intervention and generating option. Initiative develop in subsequent step of the

Framework should address the problem identified.

3.1.1 Framework

Figure 3.2 Framework

23

According to the framework in Figure 3.2, first nutritionist will login into the

system then nutritionist can manage the Food Intake Apps to insert the

information and generate report. Nutritionist is responsible to update and delete

the information. Second, user need to register first before login into apps to able

to manage their food, informatin and weight when they need tu update. Then all

the information will be store in database.

24

Figure 3.3 show of context diagram in Food Intake For Diet. There are two main

users in this systems which consist of user and nutritionist or admin. This

diagram show the flow for in and out from the data which is used by the user

and nutritionist itself, in the early stage where user can register and login to

access into the system and to used them.

3.2.1.2 Data Flow Diagram (DFD)

In the Data Flow Diagram (DFD), it will explain on how the data is inserted and

sent into the system to be processed and stored. Data flow diagram is also a two-

dimensional diagram that consists of entities, processes and files to show the

flow of the data in this system.

25

3.2.1.2.1 Data Flow Diagram Level 0

Figure 3.4 Data Flow Diagram Level 0 of the application

Based on the Figure 3.4 above, DFD shows the process that has been done

which consist of two entities i.e. user and nutritionist (admin). The proses of

the system are register, login, manage food intake, manage weight, exercise

and generate report.

26

Process 1.0 : Register

In register process, new users are required to register and fill in the

information in order to open a new account and the information will be

stored and to be insert into user files in the systems.

Process 2.0 : Login

In login process, user and nutritionist (admin) are required to log into the

system to access using username and paswword. And then the system will

verify the username and password that given from user and nutritionist file.

Process 3.0 : Manage Food Intake

In manage food intake process, nutritionist will manage including add,

update and delete the meals information from food intake file and it will be

save and stored in database if we change the information. The user can add

and delete the meals if the recommended food cannot be eaten by users, so

that it will remind the users what food they need to take.

Process 4.0 : Manage Weight

In manage weight process, user can manage and update their weight if there

is any changes on their weight and to see whether the diet process is effective

or not. Then the information change by the user will be save and stored in

the database.

27

Process 5.0 : Exercise

In exercise process, user can follow the suggestion provided to do exercise

by following the steps guided in order to speed up the process for losing

body weight. It also provide the guide step on how to do the exercise.

Process 6.0 : Generate Report

In generate report process, nutritionist can generate report from all files for

record and user can generate and get the report with monthly or weekly

report of their success loss weight following the period taken to be success

in losing weight. Then all the information will be obtained from the

database.

28

3.2.1.2.2 Data Flow Diagram Level 1

Data Flow Diagram Level 1 show the processes in DFD Level 0. There are

DFD Level 1 that will be explain is register, manage food intake, manage

weight and manage exercise. From there, it will be divide and described

according to the process.

1. Register

Figure 3.5 DFD Level 1 of Register process

29

In the process of Register as in Figure 3.5, user can register and required

to enter their personal information like (name, age, gender and email),

insert their weight, and insert username and password. Then user can

submit their data and data will be store in database and system will

display the details to user.

30

2. Manage Food

Figure 3.6 DFD Level 1 of Manage Food process

In the process of Manage Food as in Figure 3.6, nutritionist will add the

diet plan into the database and nutritionist can edit and delete the details.

The user also can add their meals and delete back if they won’t eat it. And

all information that change will be update and save in the database and

display in intercafe.

31

3. Manage Weight/ Height

Figure 3.7 DFD Level 1 of Manage Weight/Height process

In the process of Manage Weight as in Figure 3.7, user can manage their

weight by updating or change their weight if they loss weight and submit

the change into database. Than it will display them in user interface.

32

4. Manage Exercise

Figure 3.8 DFD Level 1 of Manage Exercise process

In the process of Manage Exercise as in Figure 3.8, the nutritionist will

add the exercise detail information in database. Then the nutritionist can

edit the detail and also can delete if not needed and submit the detail to

save into database. And lastly all changes will be display in interface.

3.2.1.5 Storyboard

A storyboard is a sequence of drawings, typically with some directions and

dialogue, representing the shots planned for someting like filemn or create the

system or apps. A storyboard is a graphic representation of how your apps will

unfold, step by step and etc.It’s made up of a number of squares with

illustrations or pictures representing each step,and what’s function that have in

the script. Think of it as sort of a comic book version of your script. this is my

storyboard of Food Intake for Diet mobile app.

3.2.1.6 Prototype

A prototype is an early sample, model, or release of a product built to test a

concept or process or to act as a thing to be replicated or learned from. It is a

term used in a variety of contexts, including semantics, design, electronics, and

software programming. This is prototypy from Food Intake for Diet mobile

apps that will develop soon. And we show you step by step to using this apps.

3.2.2 Data Model

3.2.2.1 Entity Relationship Diagram (ERD)

Figure 3.13 Entity Relationship Diagram of application

41

The entity relationship diagram as in the Figure 3.13 are showing the

relationship between each entity that have in the system and each entity have

their attribute that support the entity. Based on the Food Intake For Diet, the

entity that have in diagram is User, Nutritionist (admin), Weight, Exercise and

Food Intake.

In the user entity it contains with user id as primary key, name, weight gender

and email. The user are required to input the information or detail about

themselves and the data will be save in database. The nutritionist entity is

contain with username and password. While in the weight entity contains with

user id as foreign key, weight id as primary key and height. Exercise attribute is

contains with exercise id as primary key, exercise name, and exercise note. And

for food intake attribute is user id as foreign key, food id as primary key, food

name, food group and food note.

3.3 Conclusion

To conclude overall, from this chapter it explained about the modeling and design

of the mobile application. Furthermore it shows that a good designed database

gives us to access the information. This is why at the end of the app;ication it will

meet the database that is importance for applications.
