Avoid heavy or processed food.
Eat vegetables in every meal and lean meat or fish.
Drink water constantly throughout the day.
Work out everyday for atleast half an hour.
I worked out for three hours a day to lose weight. An hour in the morning and two hours in the evening (it was a killer and I really dunno how the hell I did it!)
Sleep is vital, get atleast 8hours a night.
Have a routine it helps
Give yourself a target and only weigh yourself every 2weeks or at the end of the month it'll be more of a motivation because you'll have lost quite a bit.
Good luck chick! <3
