Detecting patterns in the dataset for different ages and genders

I have some data for some participants with age, Gender, Date and meals as below. Part of the data are shown below for 3 participants:

User ID      Age       Gender         Date              Meals           
    1         20           F        04-02-2020            2   
    1         20           F        05-02-2020            3  
    1         20           F        06-02-2020            2 
    1         20           F        07-02-2020            3
    1         20           F        08-02-2020            3
    2         15           M        09-02-2020            2 
    2         15           M        10-02-2020            1
    2         15           M        11-02-2020            3
    2         15           M        12-02-2020            3   
    2         15           M        13-02-2020            1  
    3         29           F        14-02-2020            2 
    3         29           F        15-02-2020            1
    3         29           F        16-02-2020            2
    3         29           F        17-02-2020            2 
    3         29           F        18-02-2020            3
 

The task is to show detect pattern in the sample for different age or/and gender groups.

Any suggestions?

Many thanks, Shosho
