The best way to approach healthy changes is to focus on new healthy behaviors rather than the current ones you’d benefit from changing. For example, if you spend your energy preparing and packing a healthy lunch and snack bag at home the night before, you won’t need to worry about eating the unhealthy foods in the break room, cafeteria, restaurant or vending machine.
There are clear-cut behaviors that help you reach and maintain your weight and health goals. Many of these involve making a change from pre-surgery behavior.
