An overnight change in lifestyle to lose weight and change eating habits is unrealistic. A period of four to six months to reach goals is more realistic, with a plan to make adjustments if needed.

To make healthy lifestyle changes easier, start with small changes. Gradual change is easier to make part of a daily routine and to maintain over time. Eat together as a family, drink milk or water instead of soda, and take a walk together after dinner.

Set realistic goals that allow you to see results for each family member and set family goals. A child's goal might be to eat fruit or raw carrots as an afternoon snack. An adult goal might be to walk or exercise three days each week. As a family, the goal might be to avoid fast-food meals and make eating out a treat.

Reward successes frequently to stay motivated. Praise your child when he or she reaches a goal or asks for a fruit snack instead of cookies. Families can decide as a group on a reward for meeting goals. For instance, the reward may be a special trip or a night at the movies.
