If you are having trouble making your diet healthier, start by eating anything you eat slower. A lot of people out there are fast eaters so they shove down plate after plate of fatty foods, tending to overeat before they even realize they are full. This habit leads to more calorie consumption which is a large cause of weight gain.
Sign up with an online community that focuses on weight loss. Not only will you get valuable information, but you will be in a support group that will keep you motivated in your endeavor. This is also a good support system for people who are too self-conscious to join a group in person.
Ignore what your scale says. A lot of people find themselves easily discouraged when their scale does not indicate that they are making immediate progress. If you are exercising and dieting properly, just ignore the scale entirely. Keep up what you are doing. It might take a little while, but eventually you will begin to see results.
