This is good for losing weight, because you like to eat something while watching TV. Moreover, most people who watch less TV have a more energetic lifestyle, which not only increases their intake but also increases their energy consumption.
Seeing this, did you immediately think: I want to watch less TV, no, the more I think about it, the more I can't help it. What TV do you want to watch? Watch less TV dramas and variety shows without nutrition, and watch more BBC documentaries and English learning programs. ...
You can also start to add some energetic things to do, such as volunteering in the community, dancing square dance with your aunt in the community, and going out for a walk ... There are more dynamic things, so you naturally spend less time watching TV.
