I don't really want to gain weight now because I should stay at home
can I lose weight if I'm lying in bed with a kcal deficit and just watch Netflix
If you are only in bed, you will definitely gain weight with a normal diet!
Yes, of course. The body consumes calories during the day, called basic requirements, for the maintenance of basic functions
Who says you have to increase it?
Just because you are at home?
Balanced nutrition and sports exercises in the house (and any garden) are possible.
Calories can also be burned in the household.
Have a look at YouTube some fitness experts show exercises that you can also do in bed. For me, the exercises work very well.
