Impact of food delivery services on healthy- and eating behavior Assignments | Collage Homework Help

My bachelor thesis needs to consist of 15-20 pages. I’m struggling with starting my literature review, so that is why I ask for your help. Maybe if you can give me a push in the right direction, that would be great. My main subject and research question is about the impact of food delivery services on eating behavior and healthy behavior. It is a very new area so there is not much research done. That’s why is was thinking to work with some side topics (7):
(1) Obesogenic environment
Food is more available, cheaper and a drop in the quality
Almost everybody has access to it and a lot of variety
A lot of temptation
Bending machine?
(2) Sedentary life
A trigger to call food delivery
(3) Dieting
Even harder now with all the options, it’s a sort of temptation
(4) Genes vs. environment/nature vs. nurture
The environment is a continuous trigger
(5) Physical activity
(6) Newspapers with data situation COVID-19
Increase in food delivery request?
Sedentary life/physical activity?
(7)Target group
The age group that is most hit by this phenomena
Website food delivery: statistics? Proportion of income? Target group they adres to?

Because you are helping me out with the start of my bachelor thesis, I suggest that you cover the introduction (2-3 pages) and already chose 2 or 3 side topics to do, depending on the information of the side topics ofcourse?
