first thing to know is DONT STARVE YOURSELF if you do that
a.you will get back all the weight you had lost
b.well speaking of difficulties…..you might get quite a lot of them if you starve yourself
i hate to say this but not all diets work for everyone, but good general advice : eats lots of salad, fuit, vegetables ,and try to be active
and lastly tell your parents or a big sister cuz its important for you and your kids
