please help - advice on getting started

nella41

i am 19 years old, 5'5 and 11 and a half stone
my goal is to lost at least 2+ stone this year.

could people help me, i'm not sure how long it would take me to lose this weight? could it be done by june?
i put into the app to lose 1.5 pounds a week but i may possibly want to lose 2?

i have a gym membership and already eat relatively healthy but from now on i'm cutting out all the take aways and junk food especially since the festive period is over.

could someone give me advice on how long it will take me to achieve my goal? will i be toned up by then?
and what sort of exercise should i be doing?

any help would be appreciated, also please feel free too add me on this, could do with any extra motivation!
