Losing weight depends mainly on the food choices you make. Your meals should consist mainly on wholegrains, lean proteins, vegetables and fruits. Remember to drink as much water as you can! (Usually 8 glasses or more for adults) Be active and exercise frequently.. More than 2.5 hours of exercise a week would be good. Mix up cardiovascular exercises such as running and swimming with weights! Lifting weights is a great way of losing weight :) All the best!

Cally's answer is great! Here is a free website I go to every day that tracks the exercises you do. If you are lazy like me, this site gives you motivation to exercise, because it gives you rewards (points) for each exercise. Like, walking 2 miles is 30 points, for example. You can talk to people who have the same weight loss goals as you do. It's like Facebook for exercising, lol. www.fitocracy.com
