Loosing weight does not need to be hard or become a science, loosing weight should be enjoyable and a happy time. The worst thing you can do is to look in the mirror, this will only get you down. You should also not measure your weight everyday, this will also discourage you because your weight will fluctuate each day. weigh yourself once a week or every other week and reward yourself after each successful weigh in. Have a cheat day for each successful weigh in.
Happy weight loss to everyone trying, I know you can do it!
And Have Fun!
