It is all about input and output when u wanna lose weight, fat.
Can try survey ur food option, ur daily diet, google about the calorie of all of them and then adjust among them.
And rmbr to made a balance diet since u dont wanna become malnourished rite.
I am impressed by those nutritionist coz they can come out with a diet for those ppl who pregnant at 9 month, but only the belly turn bigger.
