Daily Calorie Intake

Did You Know?

Keeping a healthy lifestyle consists of adapting our daily food intake with our level of physical activities. The calories we intake (by eating food) has to roughly match the calories we burn throughout the day.

Your Challenge

For this challenge you are going to write a Python program that asks the user for their gender (Male of Female), their lifestyle (Sedentary, Moderately Active, Active) and their age.
The program will then tell them what their daily calorie intake should be.

The program should make use of the following table of data:

Gender	Age (years)	Sedentary	Moderately Active	Active
Female	2 to 3	1000	1200	1400
	4 to 8	1200	1400	1800
	9 to 13	1600	1900	2200
	14 to 18	1800	2100	2400
	19 to 30	2000	2200	2400
	31 to 50	1800	2000	2200
	51+	1600	1900	2200
Male	2 to 3	1000	1200	1400
	4 to 8	1400	1700	2000
	9 to 13	1800	2200	2600
	14 to 18	2200	2700	3200
	19 to 30	2400	2700	3000
	31 to 50	2200	2600	3000
	51+	2000	2400	2800

Learning Objectives

By Completing this learning challenge you will use:

• Nested If Statements,
• Comparison Operators such as ==, !=, <, <=, >, >=,
• Boolean Operators: AND or OR.

Tip:

Complete this task progressively using the following 3 steps:

Step 1:

Start by asking the end-user for their gender.
If their gender is Male display your calorie intake is around 2400 calories for a man, or 2000 for a woman. If you need a reminder on how to use the input, if and print instructions in python check this page.

Step 2:

Add an input at the beginning to ask the user for their age (in years). Convert this input to an integer using the int() function. Use nested if to display the right daily calorie intake based on both the gender and the age. (Use the data from the first column, “sedentary” at this stage.)

Remember when using nested if statements to indent your code accordingly.

Step 3:

You can now use a third question to ask the user if they are “S” – Sedentary, “M” – Moderately Active, “A” Active.
Use a third level of indentation/nesting to complete this challenge using all the data from the given table.

Your Code:

Extension Task:

Ask the user how many calories they have eaten so far (this day) and return the number of calories they can still have till the end of the day to match their recommended daily calorie intake.
