A good way to stay fit is to avoid eating snacks like chips or cookies. These foods might taste good, but they're very poor in nutrition and won't help you reach your fitness goals. Instead, try snacking on a handful of almonds, or even some pretzels.
Do not weigh yourself every day. There will be days when you might show a 2 pound gain, other days, when you show a 2 pound loss. That's to be expected. But you don't want to be discouraged by the "false loss". Pick a certain time of day, and the same day of the week for your weigh-in.
Eating a high-fiber diet can help you lose weight. Foods that are rich in fiber make you feel more full, so you won't be tempted to eat as much. Start your day off with a high-fiber breakfast. A bowl of oatmeal or other whole grain hot cereal is a good choice. Try topping it with some fresh fruit.
